• Strong Python skills (FastAPI, async, Pydantic) 
• Experience with SQL (PostgreSQL), Pandas, and data pipelines 
• Solid understanding of HTML/CSS/JavaScript
• Hands-on experience with Docker, Kubernetes, Azure, Kafka 
• Experience with CI/CD and Git-based workflows

Why Join Us 

• Remote-first culture – work from anywhere

• No bureaucracy or micromanagement – transparent and fast decision-making 
• Direct product impact – your work ships quickly and is visible in production 
• Real ownership – influence architecture and technical direction 
• Unlimited paid vacation and paid sick leave 
• Company-provided equipment 
• Premium AI tools subscription (ChatGPT, Copilot, Claude) 
• Professional growth – opportunity to own a technical domain or lead a module as the company scales

We’re looking for a Chief Executive Officer (CEO) to take full ownership of one of AIBY’s core product groups — up to $70M ARR consumer subscription business — and scale it into its next phase of profitable growth.

Your mission – maximize the Net Profit and Long-Term Value (LTV) of your multi-platform portfolio of apps across iOS, Android, and web by aligning product innovation with data-driven performance marketing.

Unlike a solo founder, you aren’t starting from zero. As a Business Unit CEO, you have:

• immediate access to AIBY’s historical data from 70+ apps to see what works
• centralized Legal, Finance, and HR so you can focus 100% on the product and the users
• significant UA budgets and infrastructure already in place

What you will do:

• P&L Ownership: you’re 100% accountable for the revenue, marketing spend, and operational costs of your unit
• Strategic Roadmap: define the “Why” and the “When”. You decide which features to build based on their projected impact on retention and monetization
• Growth & Monetization: work hand-in-hand with your UA Lead to optimize ROAS (Return on Ad Spend) and Payback Periods. You’ll oversee the subscription funnel, A/B testing, and paywall optimizations
• Cross-Functional Leadership: build, structure, and scale a high-performing team across Product, Growth, Marketing, Engineering, and Design
• Resource/ Capital Allocation Strategy: you have the autonomy to decide where to “bet” your resources. If a specific app in your unit is scaling, you pivot the team’s focus there immediately
• Partnership with the Board and Founders: you’re involved in strategic decision-making at the C-level, with direct impact on business metrics, financial results, and the product ecosystem

What you should have:

• 7+ years of experience in product-based B2C businesses (subscription, mobile/web)
• 3+ years in leadership roles with direct P&L ownership (CPO, CMO, GM, CEO, Product Director, Head of Product, Head of Marketing, etc.)
• Product-Marketing Hybrid expertise: you can speak “Engineering” to the devs and “ROAS” to the marketers. You understand how a product change affects ad performance and vice versa
• Proven 0→1 and scale-stage experience: launching new units, restructuring businesses, scaling early-stage products to meaningful revenue, or founding a startup
• Strong financial acumen: you live in the dashboards. You understand the nuances of cohorts, LTV/CAC ratios, and churn rates in a subscription-based model
• Mentality: ownership, clarity, decisiveness, speed, and persistence
• Entrepreneurial mindset

What we offer:

• Full strategic and operational ownership of a multi-million ARR business unit
• Competitive fixed compensation + performance-based bonus + long-term incentive structure
• The opportunity to scale a category-leading product portfolio into a global market-defining player
• Results-oriented colleagues committed to scaling impactful products. Your team will help you achieve the most ambitious goals
• Remote-friendly work environment with high autonomy and minimal bureaucracy

Location

AIBY is a team of strong international top talents. This role allows for either hybrid (combining in-office and remote work), fully remote or in-office work.

With over 70 products and 3 billion installs worldwide, AIBY is at the forefront of mobile-first product development with a focus on AI technology. Innovation and team spirit are the backbones of our company, and thanks to them, we’re proud of titles like ChatOn, iScanner, ARTA, Forma, OnSkin, Plantum, and many others. At AIBY, you can enjoy the work you do while helping millions of people.

This is a build-and-own role, not a maintain-and-report one. As Head of Marketing, you’ll decide where the budget goes, which channels win, and how fast we scale web acquisition across a multi-product Business Unit. You set the strategy—nobody hands it to you.

Your portfolio: 6+ cross-platform apps across web, iOS, and Android. ChatOn, an AI chatbot assistant with 100M+ downloads, is your anchor product—one of AIBY’s flagship apps by both revenue and downloads—and you’ll keep scaling it while picking up earlier-stage products and turning them into the next ChatOn.

From day one, you’ll lead a team of up to 10 direct reports, including User Acquisition and ASO Managers, and build the performance marketing function that drives real, measurable growth for the Business Unit. You’ll report directly to the Business Unit CEO.

What you will do:

• Own Performance Marketing for the Business Unit end to end: strategy, budget, priorities, results
• Make web acquisition the main growth priority while mobile keeps growing at pace
• Decide how budget gets allocated across products, channels and geographies, and back those decisions with numbers
• Own unit economics: plan it, forecast it, hit it
• Run ASO as part of one acquisition engine, not a side function
• Hire, coach and raise the bar for your Marketing team
• Squeeze more out of every channel, audience, creative and funnel—testing never stops
• Make Creative and UA work as one team, not two
• Partner with Product and Growth on what actually moves acquisition, activation and monetization

• Build the reporting and processes that let everything scale without you in every meeting

   

What you should have:

• 5+ years in Performance Marketing, with hands-on ownership of User Acquisition for subscription-based products, both mobile and web
• 3+ years in a leadership role with direct accountability for growth metrics— revenue, CAC, ROMI
• Confirmed cases of scaling web acquisition—numbers you can talk through, not just channels you’ve touched
• Channel mastery: Google, Meta, TikTok, Applovin and beyond. You can walk into any ad account, read what’s wrong, and tell the team exactly how to fix it
• Deep understanding of unit economics, attribution, forecasting, and marketing analytics
• Experience owning significant marketing budgets, from allocation to defending the numbers behind it
• Leadership experience with direct reports—you’ve hired, mentored, and made hard calls when needed. You know what a high bar looks like, and you hold it

What we offer:

• A real slice of AIBY’s entire portfolio in your hands—6+ cross-platform apps out of 70+ across the company, anchored by the flagship app by both revenue and downloads. Mature product, proven demand, real budget. We move at scale
• Beyond that, you’ll get earlier-stage products with no fixed growth strategy yet—real space to build the approach from scratch, not just optimize someone else’s
• Competitive fixed compensation + generous performance-based bonus
• A full creative machine in-house: motion designers, graphic designers, brand, PR, influencer marketing. You orchestrate—they execute. No agency dependency
• Results-oriented colleagues committed to scaling impactful products. Your team will help you achieve the most ambitious goals
• Remote-friendly work environment with high autonomy and minimal bureaucracy

Pine Software Technology Ltd is a software company specializing in trading technology solutions for regulated brokers and trading firms. We build SaaS products that support electronic trading, brokerage operations, risk management, and financial data analysis. We are looking for an experienced and hands-on Technical Lead Trading Platform to own and lead our core trading infrastructure. In this role, you will act as the technical and operational lead for the Trading Platform direction, overseeing 4 engineering teams. You will bridge strong technical authority with people leadership, driving core re-architecture programs while growing engineering leads and ensuring high-delivery standards.

Responsibilities:

— Own the target architecture of the Trading Platform direction: Market Data, OMS/EMS, WPF trading terminal and news streaming — within the company-wide architectural principles, including design reviews, the ADR register and final say on architectural decisions local to the direction.
— Lead the two ongoing full re-architecture programmes of Market Data and OMS/EMS, including migration staging, dual-run and reconciliation strategy, transition criteria, rollback planning and delivery without interruption of the trading session.
— Lead and develop four Engineering Leads, including one-on-ones, goal setting, performance management, development plans, calibration of their teams’ performance reviews, compensation proposals, hiring and separation.
— Own delivery predictability across four teams, including planning, capacity management, delivery and quality metrics, and regular reporting to the Head of Engineering.
— Own the engineering bar of the direction, including coding standards, code review practices, definition of done, and technical debt management across the teams.
— Oversee production operations of the direction, including release management, SLA compliance, incident response, and post-mortem follow-through; coordinate the work of the development teams with L2 support.
— Act as the primary technical point of contact for business, product, design, QA and SRE within the Trading Platform direction: architecture, technical solutions, feasibility and implementation approach — how things will be built. Scope and priorities remain with the product vertical.
— Own the direction budget and technical roadmap, including headcount planning, vendor and infrastructure decisions within approved limits, and quarterly and annual goal setting.
 

Requirements:

— Production experience with low-latency, high-throughput systems — market data and/or order routing and execution — at a scale comparable to billions of messages per trading session and thousands of messages per second.
— Deep distributed systems expertise: consistency trade-offs, fault tolerance and failover, backpressure, state replication and recovery, determinism and replay, latency tail diagnostics.
— Proven experience leading a large migration or re-write of a system in production without business interruption, including dual-run, reconciliation and rollback strategies.
— С# or python or C++ at a level sufficient to read code, run design reviews and argue technical decisions on the merits with senior engineers. Writing production code is not part of the role.
— At least 2 years of managing managers — one or more team leads with their own teams as direct reports. Managing a single team of engineers does not meet this requirement.
— Demonstrated experience growing an engineer into a team lead, and handling a team lead who was not performing.
— Experience in an environment with L2 on-call, SLA commitments and formal incident management, including building a blameless post-mortem culture.
— People management practices: performance management, development of managers, hiring, capacity planning and prioritization.

Deal Baker is a practice, not a dev shop — we don't sell hours and we don't staff projects. Our CTO gets on a call with the owner of a business, diagnoses the build while he's still on that call, prices it there, and then holds a weekly call with that client for as long as they're a client. Five production systems in five unrelated industries. Paying clients since 2023. Revenue that renews monthly. Delivery runs on agents rather than headcount, so there's no bench to feed, no ramp, and no three-week silence while somebody gets staffed.

We win the calls we get. We just don't get many. Every client we have came by referral. There's no list, no playbook, no outbound, no channel — nobody here has ever gone looking for a client. That's the seat.

Who we want. A senior BD out of software outsourcing who already knows the right people. Employed, independent, or between things — we don't mind which. You know this buyer, you know the objections, you know what a build actually costs and why the estimate is always wrong. You won't be closing — our CTO does that on the call. Your job is getting the right owner onto his calendar, and knowing which owners are worth his sixty minutes.

This is a second thing, not your next job. Commission only, so it can't be what covers your rent. If you're employed, read your contract first — we won't be the reason you breach one. Your employer's clients are theirs. Your own relationships are yours.

Money. No base. Bonus €5k per client.

Time. Fully flexible, work your own hours.

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.).

What We're Looking For

Role Overview: We are developing Ask Seeking Alpha — a high-load financial analysis system based on Large Language Models. The architecture is built on complex multi-agent orchestration using LangGraph, FastAPI, and Elasticsearch.

We are looking for a Senior Backend Engineer specialized in Generative AI to design agent workflows, optimize interactions with models (OpenAI, AWS Bedrock), and ensure the reliability of non-deterministic systems in production.

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

Tech Stack: Python (Asyncio), FastAPI, LangChain, LangGraph, Pydantic, Elasticsearch, AWS Bedrock / OpenAI API, LangSmith.

What You'll Do

• Agent Architecture: Design and implement complex agent orchestration logic using LangGraph. You will define state management, conditional routing, and error handling within the agent graph.
• Tool Engineering: Build and optimize the tool layer (function calling) that allows LLMs to interact with internal financial APIs and databases accurately.
• Performance Optimization:

-Reduce end-to-end latency through asynchronous processing and streaming (SSE).

-Implement semantic caching strategies to minimize API costs and response time.

-Optimize token usage without sacrificing answer quality.

• Observability & Evaluation: Implement automated evaluation pipelines using LangSmith. You will be responsible for setting up regression testing for prompts and agents to measure quality (correctness, faithfulness) before deployment.
• Advanced RAG: Refine retrieval strategies. Work on hybrid search implementation (Keyword + Vector), re-ranking, and query expansion to feed the most relevant context to the model.

Requirements

• Python Expert: Strong proficiency in modern Python. Deep understanding of asynchronous programming (asyncio) patterns is mandatory, as our entire I/O pipeline (Network, DB, LLM) is non-blocking. Experience with FastAPI and Pydantic (v2).
• Agentic Frameworks: Production experience with LangChain. Hands-on experience or deep conceptual understanding of LangGraph (or similar state-machine-based agent frameworks).

Deep LLM Expertise (What we mean by "Deep"):

• Non-determinism Management: Strategies for handling LLM hallucinations and ensuring reliable outputs (e.g., self-correction loops, specific prompting techniques like CoT/ReAct).
• Structured Outputs: Experience forcing LLMs to adhere to strict schemas (Pydantic/JSON mode) for reliable downstream processing.
• Context Optimization: Advanced strategies for managing limited context windows (summarization chains, sliding windows, selective context injection) beyond simple truncation.
• Inference Economics: Understanding the trade-offs between model size, latency, and cost (e.g., when to route to GPT-4 vs. a smaller/faster model).

Nice to Have

• Experience with Elasticsearch (DSL queries, analyzers).
• Knowledge of vector databases and embedding models.
• Background in FinTech or familiarity with financial data structures.

Responsibilities

• Product Strategy: Define and execute product roadmaps aligned with business objectives, user needs, and company vision.
• Proactive Initiative Management: Proactively explore new opportunities to expand the product offering within the live-streaming ecosystem, driving innovation in a constantly evolving space.

• Data-Driven Decisions: Use data insights, user feedback, and industry trends to inform product decisions and enhance the user journey.
• Performance Monitoring: Define success metrics, track results, and iterate to continuously optimize product performance.
• Stakeholder Collaboration: Act as the central point of communication between business and technical teams, ensuring alignment and clear communication of priorities and goals.
• Production-Focused Execution: Adopt a "ship-to-production" mindset, prioritizing speed, impact, and quality in every release.

Requirements

• At least 5 years of experience in product management, ideally in fast-paced tech or consumer app environments.
• Proven track record of launching and scaling successful products that drove measurable business results.
• Strong analytical and strategic mindset, with the ability to make clear, data-informed decisions.
• Excellent communication, collaboration, and stakeholder management skills across disciplines.
• Full professional proficiency in English, both written and verbal.
• Hands-on experience with product analytics tools (e.g., Amplitude, Mixpanel, Looker).
• A plus: Experience in the gaming, social, or monetization industries, managing in-app purchases and virtual economies.
