Position: Head of New Business Sales & GTM — U.S. Market

We’re looking for an experienced, hands-on Sales & GTM leader who can build and scale new revenue streams for CTC Stack.

This is not a role for someone who only manages an existing sales team or waits for a finished sales playbook. We need someone who can identify commercial opportunities, build pipeline, personally close B2B deals, manage a sales team, and turn successful sales approaches into repeatable growth systems.

Key Responsibilities:

• Build and scale new B2B revenue streams in the U.S. market.
• Develop and manage a qualified sales pipeline across CTC Stack products, services, and new verticals.
• Personally lead discovery calls, proposals, negotiations, and closing of strategic B2B deals.

• Identify new partnerships and business development opportunities.
• Analyze lost deals, objections, market feedback, and conversion data to improve the sales process.
• Build structured forecasting and maintain strong CRM and pipeline discipline.
• Help turn successful commercial experiments into scalable revenue systems.

Key Qualifications:

• 3+ years of experience in B2B Sales, Business Development, GTM, or Revenue Growth.
• Strong experience selling to the U.S. market.
• Proven track record of personally closing B2B deals, not only generating meetings.
• Full-cycle sales experience: prospecting → discovery → proposal → negotiation → close.
• Experience managing and developing SDR / BDR / Sales teams.
• Proven experience growing revenue and building sales pipelines.
• Experience selling to business owners, founders, CEOs, or senior decision-makers.
• Strong consultative and solution-based sales skills.
• Ability to build sales processes in an environment where not everything is already structured.
• Strong commercial thinking and ability to identify new revenue opportunities.
• Fluent English.

Would be a Plus:

• Experience selling AI, automation, SaaS, CRM / RevOps, MarTech, or technology solutions.
• Experience with performance marketing, lead generation, high-ticket agency services.
• Experience selling custom software or business process automation.
• Experience launching new products or entering new verticals.
• Experience in logistics, healthcare, dental, or other U.S. service industries.

Who We’re Looking For:

We’re looking for someone who wants to build, not simply maintain.

You should be comfortable working with evolving products, testing new approaches, challenging offers when the market is not responding, and taking real ownership of commercial results.

You should be equally comfortable leading a team and personally closing important deals.

Success in this role will be measured by new revenue, qualified pipeline, closed clients, sales team performance, and the ability to build repeatable GTM and sales systems.

Please apply with your CV, examples of B2B deals you closed, measurable revenue or pipeline results, and your expected compensation!

Hi, I'm Vadim, CTO of Lexidesk. 

We make AI agents that answer the phone for law firms in the US and UK. When someone calls a lawyer at 2 a.m. after a car accident, our agent picks up, asks the right questions and books the consultation.
 

Every firm gets its own agent, and a person has to teach it: how the firm talks, which cases it takes, what to ask each caller. You do that in plain English by writing the agent's instructions (the prompt). We have more new firms than people to set them up. That is the job.
 

A job that didn't exist three years ago
 

There is no degree for this and no textbook. The technology changes every month, and nobody will hand you a manual. You'll learn by reading, trying things and working them out yourself. If that sounds like freedom rather than stress, keep reading.

I think this is a job of the future. You'll be the one building the AI, not the one being replaced by it.
 

What you can earn
 

$700/month from day one, $1,000–1,500 after promotion. You can earn serious money here if you put in the work. $1,500 a month is not the limit: we are ready to pay up to $3,000 to anyone who becomes a real pro at writing prompts and supporting our law firm customers.
 

Why we train from scratch
 

Real prompt engineers are hard to find. Plenty of people use the title, but very few can do the work. So we built our own training program and teach people from zero. To start, all you need is strong English, some charisma and a lot of perseverance.
 

Working hours
 

Most of our customers are American, so we work in the second half of the day: 13:00–21:00 Kyiv time, or 13:00–22:00 if you want a one-hour break.
 

What you'll do
 

• Set up the agent for each new law firm: write its instructions, choose its settings, then call it yourself to hear how it performs
• Listen to real calls and read transcripts, find where the agent went wrong and work out why
• Rewrite the instructions and test again until it's right
• Talk to law firms by email, chat and video call about what they want changed
   

What you need
 

• C1 English. You'll write instructions that an AI follows word for word, and you'll speak with American and British lawyers
• A quick mind. You can learn a new tool in a day and you enjoy working out why something went wrong
• Real curiosity about AI. You already use ChatGPT or Claude a lot and want to see how it works from the inside
• The habit of teaching yourself. When you don't know something, you go and find out
   

What you don't need
 

• Experience. None at all
• Programming. This is not a developer job. A prompt is a kind of program, but you write it in plain English
• Legal knowledge. We'll show you our product and how law firms work. The rest you'll learn by doing
   

Be honest with yourself
 

This is a full-time job that needs your whole working day, so it won't fit around university classes. It is also a full day at a computer: reading, listening, writing, testing, then doing it all again. Some people find that draining. The people we want enjoy exactly this kind of focused work.
 

The first three months
 

For the first three months you will compete with the other trainees, and if you learn more slowly than they do, you won't stay long. If you think of yourself as a slow learner, your chances are low. It will be a real competition and it's not for the faint-hearted. But it will be real, and I think real is rare these days.

You will learn by doing the most practical work possible, with the best documentation and training program we can give you. If you get through all of this and build real skill, you will be promoted. That is guaranteed.

Professional skills:

• Experience in advanced Linux/Unix command line interface and utilities (CentOS, Debian, Ubuntu). Will be a plus to have knowledge in FreeBSD, pfsense, Mikrotik CHR
• Experience as advanced user in Windows 2012, Windows 2016, Windows 2019, Windows 10

• Good knowledge of HW RAID (MegaRAID, 3ware), SW RAID (mdraid), ssh, ping, iptables, mtr, tcpdump, telnet, rsync, curl/wget, dig, scp, cron, nslookup, whois, smartctl, git. Will be a plus to have knowledge of ansible, ebtables, Network equipment (Juniper EX4200)
• Will be a plus of knowledge Virtualization system SolusVM, Docker, ESXi, Proxmox
• Knowledge of bash scripting. Will be a plus to have knowledge of PHP (understanding code, simple scripting)
• Knowledge of IPMI/iDRAC/iLO.
• Will be a plus to knowledge of HestiaCP, VestaCP, ISPmanager, CloudFlare, GitLab, cPanel, Virtualmin, DCImanager, DirectAdmin
• Manage and monitor systems, troubleshooting
• Understanding of TCP/IP network stack
• Be able to work in shifts

General skills:

• Pre-Intermediate English (reading/writing), Ukrainian (reading/writing), Russian (reading/writing)
• Experience in support
• Experience in administrating (troubleshooting, logs parsing, scripting etc)
• Quick understanding and learning abilities
• Ability to work on several tasks in parallel

We offer:

• Work in a friendly team;

Here, your growth matters. We prioritize your development through ongoing learning and career advancement opportunities, helping you reach new milestones. Join Seeking Alpha to be part of a company that values your unique journey, supports your success, and champions both your personal well-being and professional goals.

What We're Looking For

Role Overview: You will take ownership of the search infrastructure for Ask Seeking Alpha — a financial intelligence platform powered by LLMs. Your main goal is to ensure our AI agents can find the exact financial data they need (articles, transcripts, news) in milliseconds. You will work on the Retrieval layer of our RAG architecture, combining traditional text search with modern vector search techniques.

Tech Stack: Elasticsearch (v8+), Python (FastAPI, Asyncio), OpenAI Embeddings, LangChain, LangSmith.

The Senior Search Engineer will be engaged with the company as a contractor (Private Entrepreneur).

What You'll Do

• Search Engine Development: Design and implement Hybrid Search strategies. You will figure out how to best combine "keyword matching" (finding specific tickers like 'AAPL') with "semantic search" (finding concepts like 'revenue growth').
• Relevance Tuning: You are responsible for the quality of search results. You will build systems to measure and improve how well the search engine answers user queries (using tools like LangSmith).
• Vector Search & RAG: Manage the integration of OpenAI embeddings into Elasticsearch. You will solve challenges related to indexing long documents (e.g., earnings transcripts) so the AI retrieves only the most relevant parts.
• Performance Optimization: Optimize Elasticsearch queries and index settings to ensure low latency, even for complex queries with many filters.
• Python Backend: Develop and maintain the Python services that build queries and process results. We use FastAPI and Asyncio heavily.

Requirements

• Elasticsearch Expert: 5+ years of experience working with Search Engines in production. You understand how indices, analyzers, and mappings work "under the hood."
• Search Theory: You understand the difference between Lexical Search (keywords) and Vector Search (meaning), and know when to use which.
• Python Proficiency: Strong experience with Python 3.10+. You are comfortable writing asynchronous code (async/await) and building APIs.
• Data Engineering: Experience designing data schemas for search (how to structure JSON documents for efficient retrieval).

Nice to Have

• Experience building RAG (Retrieval-Augmented Generation) pipelines.
• Familiarity with LangChain or similar LLM frameworks.
• Experience with Evaluation tools (like LangSmith) to test search quality automatically.
• Background in Finance (understanding tickers, earnings calls, etc.).

At the same time, we’re also dedicated to creating a workplace where our team thrives. We’re passionate about fostering a flexible, balanced environment with remote work options and an array of perks that make a real difference.

What We're Looking For

Do you look at websites and think about how they might be personalized? Do you use websites and apps and think about how their features have been designed to be best for a lot of different users? Do you read articles with statistics and think about how they may be misinterpreting the data to get their results? If these things describe you, and if you’re great at SQL and have experience analyzing website data, you’re someone we want to talk to.

We’re looking for a Senior Data Analyst with experience analyzing website data. Our data analyst team analyzes everything on our website, not only for their immediate use but also for how they connect to high-level company KPIs. Our Analysts analyze raw data, not only pre-aggregated data, to extract just the right information and diagnose what is happening on our site.

The role requires understanding web development and how data is gathered, analysis of site usage and a/b tests, data visualization, and how different kinds of data can be presented most clearly, and business KPIs and how they are measured.

But more than that, we’re looking for experienced analysts who can bring us new ideas about how to analyze and extract insights from website data. Our ideal candidates have measured KPIs that we haven’t measured or used new ways to explain user retention, or analyzed features of users' data that we haven’t analyzed.

The best thing about our work is that we’re part of an incredibly data-driven company. Everyone from the CEO down uses data every day. The data teams are involved in every single thing the company does.

What You'll Do

• Analyzing the behavior of users on our site and apps:

-Build and maintain dashboards that visualize the usage of single or multiple features and how that usage drives company KPIs.

-Answer questions about site usage or user behavior based on deeper analyses.

• Analyze and track high-level KPIs such as conversion, retention, churn, recurring revenue, engagement, cross-device usage, e-mail and notification usage, and more.
• Communicate with business stakeholders on analysis results, how they relate to business, and what business suggestions result from the analysis.
• Run the whole data flow for site and app features, from defining KPIs, specifying data collection for development team implementation, and building and maintaining iterative versions of dashboards with both low-level and high-level views of collected data.
• Split tests of product features:

-Design a test with clear success criteria

-Monitor test integrity

-Analyze results and give recommendations

-Use segmentation and clear cohort analysis to validate significant conclusions

-Conduct exploratory analysis to identify trends and opportunities

Requirements

• A minimum of 5 years in a B2C website-related Data Analyst position
• Strong SQL skills with experience writing complex and efficient analytical queries
• Demonstrated experience with working in English directly with business stakeholders, understanding their needs, and explaining results
• Understanding of website development and operations and how they connect to data gathered.
• Experience with data visualization tools (Looker/Tableau/PowerBI, etc.)
• Experience with report writing and technical requirements analysis, business process modeling/mapping, methodology development, and data modeling

We are currently looking for a Senior Full Stack PHP Developer to join a professional German-based product company team that designs innovative eHealth solutions for hospitals.

You will work on a stable healthcare product, contributing to backend architecture and supporting frontend functionality where needed.

Qualifications:

•  5+ years of professional PHP, with real depth in Symfony (DI, console, event handling, Doctrine). We run PHP 8.4 / Symfony 7.4 and stay current.
• Proven external systems integration experience: you have built and operated interfaces for systems you did not control.
• Experience with writing unit and integration tests.
• SOLID, design patterns, and clean architecture.
• Solid MariaDB/MySQL knowledge.
• RESTful APIs.
• Docker and Bash.
• Strong debugging discipline with log correlation.
• Proactiveness: you raise risks, gaps, and bad assumptions early instead of waiting to be assigned the next ticket.
• Ability to decompose an ambiguous requirement into steps that ship independently. Integration work rarely arrives fully specified.
• Clear written and spoken English.

Nice to have:

• HL7 v2, FHIR, DICOM, or hands-on work with an HIS.
• PHPStan and Psalm.
• Fluency with the failure modes of distributed integration: partial delivery, duplicates, ordering, silent schema drift.
• Experience working with JIRA and in an Agile/Scrum environment.
• Regulated-environment experience: medical devices, finance, or comparable.
• Productive use of AI coding assistants (Claude Code, Codex, or similar): you know where they genuinely accelerate work and where their output needs to be treated as a first draft, not a merge candidate.

Your tasks:

• Develop top-notch and maintainable software solutions, implementing modern engineering practices to ensure high product quality
• Engage in technical discussions to identify the best solutions and proactively propose innovative ideas
• Collaborate effectively with team members and management

What you can expect from us:

• Flexible working hours and a healthy work-life balance
• 24 paid vacation days per year + 11 public holidays + paid sick leave
• Fully remote cooperation (Ukraine or any EU country)
• PE accounting support (Cooperation is possible via Ukrainian PE (FOP) only)
• Modern equipment and a powerful laptop
• Flat structure with short decision-making cycles
• Direct collaboration with a German product company

Performa is an international HR agency specializing in connecting top talent with leading companies across the iGaming, IT, and Marketing industries. 

Our client is an iGaming company launching a new online crypto casino project as a spin-off from a large international casino brand. The project is currently at an early stage, with a core team already in place and active preparation for launch.

We are looking for a Head of Financial Operations to join the team and take ownership of the company’s financial operations across payments, treasury, crypto liquidity, custody, withdrawals, settlements, reconciliation, chargebacks, and transaction-level financial controls.

The Project

We are building a new online crypto casino project, launched as a spin-off from a large international online casino brand. This is an early-stage opportunity to join an ambitious, fast-moving and execution-driven team with real ownership and direct impact on the business. The position is based on-site in Dubai.

Compensation and the overall package are discussed individually; relocation support can be provided where required.

The Role

The Head of Financial Operations (FinOps) owns the company’s payment infrastructure and controlled movement of money across fiat and crypto rails. The role combines Head of Payments, Treasury and Reconciliation responsibilities: payment orchestration, PSP and banking relationships, liquidity, custody, withdrawals execution, settlements, chargebacks, reconciliation, payment economics and transaction-level financial controls. FinOps executes authorized financial actions and maintains the financial evidence trail.

Responsibilities

Payments and Provider Management

1. Own the payment operating model across fiat and crypto methods, including routing, cascading, failover and GEO-specific cashier configurations in cooperation with IT Department.
2. Lead the selection, commercial negotiation, onboarding and launch of PSPs, acquirers, banks, gateways, crypto processors and other payment partners within delegated authority.
3. Monitor payment conversion, technical success, payout execution, provider availability, fees, reserves, settlement terms and counterparty exposure; drive corrective action and escalation.

4. Maintain a resilient provider portfolio with appropriate concentration limits, fallback capacity and replacement pipelines.

    

Treasury, Custody and Crypto Liquidity

1. Own daily liquidity across PSPs, banks, wallets, custodians and exchanges to fund authorised withdrawals and business obligations.
2. Design and operate the hot/warm/cold wallet model, rebalancing thresholds, signing workflows and transaction-approval controls with the CFO and Risk.
3. Execute approved treasury, conversion and hedging strategies and maintain sufficient fiat/crypto on- and off-ramp capacity.

4. Monitor and mitigate FX, crypto-price, counterparty, settlement, network-fee and liquidity exposures, escalating limit recommendations to the CFO.

    

Withdrawals, Disputes and Controlled Execution

1. Execute withdrawals and other financial actions only after required system, Risk and Compliance approvals, preserving maker-checker, custody and transaction-limit controls.
2. Own payout routing, transaction submission, provider/wallet execution, status monitoring and resolution of failed or stuck transactions.
3. Administer chargebacks, refunds and payment disputes on the financial and provider side, including evidence submission, reversals, reserves and ledger impact.

4. Maintain auditable evidence for holds, releases, rejects, refunds, reversals, disputes and manual interventions; never override a Risk or Compliance restriction.

    

Reconciliation, Settlement and Financial Control

1. Own daily end-to-end reconciliation across gaming, payment, banking, wallet, custody, exchange and accounting systems, with controlled investigation and closure of exceptions.
2. Validate settlements, balances, fees, exchange rates, reserves and segregation of player-related and corporate funds.
3. Own transaction-level controls and operational subledgers, providing reconciled data and evidence for month-end close, audits and regulatory reviews (Accounting retains ownership of statutory books and financial statements).

4. Provide transaction, wallet and settlement evidence to investigations and regulatory reporting without assuming ownership of AML or fraud decisions.

    

Reporting, Process and Team Leadership

1. Own payment and treasury reporting and P&L, covering performance, liquidity, provider exposure, fees, FX/crypto costs, chargebacks, reserves, incidents and control exceptions.
2. Build and lead the FinOps team across payments, treasury and reconciliation, including 24/7 coverage where required.
3. Maintain SOPs, approval matrices, business-continuity procedures and cross-functional SLAs, and drive appropriate automation.

4. Represent FinOps in launches and strategic planning, signing off payment readiness, liquidity, reconciliation and financial controls.

    

Requirements

1. 7+ years of experience in payments, treasury or financial operations, including leadership experience; online casino, sportsbook, PSP, fintech or crypto-exchange experience is strongly preferred.
2. Hands-on knowledge of cards, bank transfers, e-wallets, acquiring, payment orchestration, refunds, chargebacks, settlements and provider reserves.
3. Strong crypto operations experience, including custody, hot/cold wallet controls, exchanges, OTC, on/off-ramps, stablecoins and multi-chain liquidity.
4. Proven ownership of high-volume reconciliation and transaction-level financial controls.
5. Strong commercial experience with PSPs, banks, custodians, exchanges or comparable payment partners.
6. Strong data skills; advanced spreadsheet capability and confidence working with APIs, SQL, dashboards or large transaction datasets.
7. Working knowledge of AML/KYC, sanctions and fraud controls sufficient to execute decisions and preserve evidence while respecting independent control ownership.

8. Fluent English, written and spoken.

    

Preferred Qualifications

1. Prior experience as Head of Payments, Head of Treasury, Head of FinOps or an equivalent role in iGaming.
2. Practical knowledge of crypto custody platforms and wallet infrastructure, including Fireblocks, Copper or BitGo, covering transaction workflows, signing and approval schemes, hot/warm/cold wallet structures, wallet rebalancing, access controls and crypto liquidity management.
3. Working knowledge of blockchain analytics and wallet-screening tools such as Chainalysis or Elliptic, sufficient to interpret screening results, identify transactions requiring escalation and execute authorised holds or releases in accordance with approved Risk and Compliance decisions.
4. Experience across multiple gaming jurisdictions and high-risk merchant banking environments.
5. Experience designing automated reconciliation, payment-monitoring and treasury-control tooling.

6. Strong mathematical, finance or quantitative background.

    

We Offer

1. A senior leadership role building the FinOps function from the ground up, with real ownership of payment infrastructure, treasury and financial controls.
2. Relocation support where needed.
3. Competitive compensation package discussed individually with each candidate.
