About the Product:

We are developing a no-code automation platform designed for enterprise IT and support teams. The product integrates with multiple third-party systems—such as cloud providers, identity services, and ITSM tools—to automate routine tasks and improve operational efficiency. Built as a microservices architecture using FastAPI and AsyncIO, the platform manages high volumes of data through Postgres and Redis, and relies on HTTP/REST APIs and OAuth for secure communication.

You will collaborate directly with stakeholders and a cross-border engineering team. While your primary focus will be on server-side components—including database interactions, task orchestration, and third-party integrations—you will also provide backup support for minor front-end tasks using TypeScript and ReactJS. You will take full ownership of your modules, identify root causes of production issues, propose architecture improvements, and contribute to our AI automation initiatives. This role offers autonomy, direct impact on product direction, and opportunities to shape a next-generation platform for enterprise IT automation.

Key Responsibilities:

• Design, implement, and maintain Python-based REST APIs and backend services using FastAPI and AsyncIO.

• Collaborate on microservices architecture, contributing to code reviews and design discussions.
• Perform root-cause analysis and debugging of production issues to maintain high service availability.
• Support some front-end tasks in ReactJS and TypeScript
• Work with DevOps and infrastructure teams on cloud-based deployments and system design.
• Leverage AI-assisted development tools to improve code quality and productivity.

Required Competence and Skills:

• 6+ years of professional experience in software development, with a focus on Python.
• Strong understanding of computer science fundamentals, algorithms, and data structures.
• Proficiency with Postgres and Redis for data storage and caching.
• Experience deploying and operating services on Azure or another major cloud platform.
• Practical skills in TypeScript and ReactJS for front-end maintenance tasks.
• In-depth knowledge of HTTP, REST API design, and OAuth protocols.
• Product-oriented mindset with experience collaborating directly with designers and stakeholders.
• Experience using AI-powered development tools (e.g., Copilot, Cursor) in daily workflow.

Nice to Have:

• Familiarity with Next.js for server-rendered React applications.
• Experience with Temporal or similar orchestration/workflow systems.
• Knowledge of message queue systems (Kafka, RabbitMQ) and event-driven architectures.

Why Us:

We provide 20 days of vacation leave per calendar year (plus official national holidays of a country you are based in).

We provide full accounting and legal support in all countries we operate.

We utilize a fully remote work model with a powerful workstation and co-working space in case you need it.

We offer a highly competitive package with yearly performance and compensation reviews.

Format: Full-time
Compensation: Fixed salary + % per closed deal
Work format: Remote

Responsibilities:

• Working with the automated lead generation system Convertix.io or similar
• Leading sales conversations with clients (chat-first)
• Qualifying leads and identifying real buying intent
• Negotiating pricing, scope, and timelines
• Deal closing

Requirements:

• Proven experience with Convertix.io or similar AI automation tools
• Strong hands-on experience with Upwork sales (not theory)
• Clear understanding of the sales funnel: proposal → reply → negotiation → deal
• Confident written English (B2+ / C1 preferred)
• Strong negotiation and closing skills
• Ability to push deals forward and drive clients to a decision

You will focus on deep discovery, understanding client business needs, structured communication, and presale collaboration, helping clients navigate complex solutions and make informed decisions.

If you are curious, quick-thinking, comfortable in calls, and genuinely interested in understanding how businesses work - you will feel at home with us.

About the company

GroupBWT is a consulting firm specializing in data management, web scraping, and custom data platforms.
We work with technically complex solutions: large-scale data scraping, anti-bot challenges, ERP integrations, and tailored data systems designed around specific business needs.

Our projects are not off-the-shelf products - they require thinking, context, and close collaboration between Sales, Presale, Delivery, and technical teams.

We are also an AWS Accredited Partner, confirming the high technical and architectural standards of our solutions.

Requirements:

• 2–3+ years of experience in IT Sales / Business Development / Presale within IT outsourcing (mandatory).
• Strong ability to understand business needs, ask meaningful questions, and think in terms of solutions, not just services.
• Experience participating in discovery calls, presale discussions, or negotiations.
• Basic understanding of software development processes and technical terminology (enough to confidently talk to clients).
• Confidence in client calls and meetings; ability to communicate clearly and think on your feet.

• Strong analytical mindset, curiosity, and the ability to “connect the dots” between business problems and technical solutions.

   

Will be a Plus:

• Experience with data-related projects (web scraping, data platforms, data engineering, analytics).

• Exposure to complex or custom IT solutions rather than simple, boxed services.

   

Key Responsibilities:

• Participate in discovery calls and client meetings, helping uncover real business needs, challenges, and decision criteria.
• Act as a business-oriented sales partner during client conversations - asking the right questions, structuring dialogue, and guiding discussions.
• Work closely with Presale / Delivery / PM teams to translate client needs into clear solution concepts.
• Explain technical ideas in a clear, business-friendly way, involving technical experts when deeper detail is required.
• Support negotiations, clarify scope and value, and help move deals forward through the decision-making process.

• Corporate training and development – access to internal educational programs, training sessions, and workshops to enhance professional skills.
• Corporate discounts and partner benefits – special offers and discounts for employees and their relatives at one of the largest gym networks in Ukraine, as well as from other partner companies.
• Support for the Armed Forces of Ukraine – the company contributes to donations and initiatives supporting the Ukrainian Armed Forces.
• Corporate events – regular team-building activities, celebrations, and internal events to strengthen team spirit
• Educational support – reimbursement or partial coverage of expenses for courses, training, and certifications for professional development
• 21 paid vacation calendar days, 15 paid sick leaves and additional days off – enjoy a well-balanced work-life schedule with paid vacation, sick leave, and extra days off when needed.

We are looking for a Head of Performance Marketing & Growth who will own the full growth engine - and drive it to scale.

This is not a "manage the metrics" kind of role. You're coming in at an active growth stage where the foundation exists - but the system needs a strong hand to scale.
Your mission: build a systematic Paid Social-first growth engine, close the loop between creative, acquisition, onboarding, and paywall - and make unit economics actually work on iOS subscription products (weekly/annual plans, trials, paywall optimization, LTV-driven economics).

You'll operate with high ownership, speed, and direct access to the CEO. This role is ideal for a UA leader whose core is mobile acquisition - and who is ready to go beyond the channel: own business outcomes, drive product and creative teams, and think in systems, not campaigns.

What You'll Own

• Full growth cycle: acquisition → ASO → onboarding → paywall
• Paid Social-first strategy with focus on Meta scaling and TikTok as a growth lever
• Creative performance as a key growth lever - strategic ownership of the creative pipeline: angles, formats, win rate, iteration velocity
• ROAS, unit economics, and P&L accountability - you're responsible for the number, not just the channel
• Building and leading a team across UA, growth, and creative coordination
• Cross-functional sync with Product, Analytics, Monetization, ASO, and Creative teams
• Defining and evolving the monetization strategy together with Product: paywalls, pricing, trial mechanics
• Direct partnership with the CEO - strategy alignment, fast decisions, no bureaucracy

Your First 3–6 Months

• Full audit: traffic sources, unit economics, creative performance, funnel conversion
• Define and launch a Paid Social growth strategy - from hypothesis to execution
• Strengthen the analytics and attribution setup - ensure the team can make confident scaling decisions based on data
• Rebuild the creative testing system if needed: win rate, velocity, feedback loop with the creative team
• Build a roadmap to traffic profitability within 6–8 months
• Set up a structured marketing - product interaction process
• Assess, structure, and stabilize the team - identify gaps, close them

What Success Looks Like

• Systematic growth appears in Meta and TikTok - not one-off wins that can't be repeated
• The creative → acquisition → onboarding → paywall loop starts working as one connected system
• Analytics delivers the numbers you need to make decisions - not the other way around
• The team has a clear leader who sets direction, removes blockers, and raises the bar

What We're Looking For

Hard requirements:

• 5+ years in B2C Mobile User Acquisition or Performance Marketing
• 2+ years in a leadership role with direct ownership over results - not just managing people, but owning numbers
• Proven track record scaling Paid Social on iOS subscription apps with significant budgets
• Deep understanding of unit economics and P&L management
• Strong command of the subscription funnel: install → trial → paid → retention levers
• Ability to connect creatives, funnels, and analytics into one coherent growth system
• Experience building and managing teams, including hiring and letting go

The kind of person who fits:

• You don't run campaigns yourself anymore - but you could. And your team knows it
• You think in systems, not tasks. You don't just solve problems - you build the structure that prevents them
• You own results. Not the process, not the effort - the outcome
• When something is unclear, you don't wait for direction. You define it
• You're equally comfortable building from zero and scaling what works - sometimes at the same time
• You push things forward. Across teams, through blockers, past excuses.

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.

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.
