About the Role

We're looking for a Senior Recruiter who lives and breathes the marketing world. Most of our open roles sit at the intersection of creative, performance marketing, and affiliate/media — and we hire only A-players. That means our recruiter needs to know this market deeply: who the strong players are, where they work, what motivates them, and what separates a good candidate from a truly exceptional one.

You'll work closely with hiring managers and leadership to close some of the most competitive roles in the market — often the kind of profiles others would call "unicorns."

What You'll Do

• Own the full recruitment cycle for marketing, creative, and adjacent roles — from intake to offer accepted: Affiliate Managers, Publishers, Broadcast & Monetisation Managers, ESP / Compliance specialists, Creative PMs, Designers, CQ/QA, and more.
• Lead role intake calls with hiring managers — ask the right questions, surface the real "must-haves" vs. "nice-to-haves," and translate fuzzy requirements into a sharp ideal candidate profile.
• Source proactively — LinkedIn, niche communities, competitor mapping, talent pools, referrals. We expect outbound, not job-board-and-pray.
• Pre-screen with strong judgment — assess not just skills and experience, but culture fit and A-player signals (ownership, drive, taste, communication, ambition).
• Manage agency partners (Oxygen, EPC, and others) — brief them well, hold them accountable on quality, and supplement their pipelines with your own sourcing.
• Run a clean process — keep our ATS (People Force) up to date, communicate proactively with candidates, and deliver a great candidate experience even when the answer is no.
• Calibrate continuously — debrief after interviews, share what's working, refine the profile, and help hiring managers sharpen their own evaluation lens.
• Partner with the internal recruitment team to share market insights, balance workload across roles, and cover for each other on domain stretch areas.

What We're Looking For

Must-have

• 3+ years of in-house or agency recruitment experience with a clear focus on marketing, creative, affiliate, or performance/media roles.
• Demonstrated ability to close hard-to-fill positions — you can point to specific senior or "unicorn" hires you've personally sourced and closed.
• Strong market map of the marketing/creative talent landscape — you know the relevant companies, the strong teams, the typical career paths, and where to fish for each profile.
• Excellent ability to read people — to spot the difference between someone who looks great on paper and someone who will actually deliver and fit the culture.
• Confident stakeholder management — you push back when a brief is unrealistic, ask sharp questions, and bring data and market reality into the conversation.
• High-velocity sourcing output without sacrificing quality — you present a tight shortlist, not a flood.
• Fluent written and spoken English — for candidate outreach, interviews, and internal collaboration.

Nice-to-have

• Background recruiting in adjacent domains (broadcast, monetisation, affiliate networks, ESP/email marketing, compliance, digital media).
• Experience working alongside external recruitment agencies and getting strong results out of them.
• Familiarity with People Force or similar ATS platforms.
• Exposure to international hiring across multiple time zones.

Who You Are

• You genuinely enjoy hunting for talent — sourcing isn't a chore, it's the part you actually like.
• You have strong taste and high standards — you instinctively raise the bar rather than lower it under pressure to close.
• You're proactive and self-driven — once you understand the role, you go.
• You're a great listener — to hiring managers, candidates, and feedback.
• You care about the long game: building a pipeline, maintaining relationships with strong candidates even when there's no role for them yet.
• You're comfortable working in a fast-moving environment where priorities shift weekly.

What We Offer

• Direct collaboration with founders / leadership and hiring managers who care about hiring well.
• Multinational and intercultural experience
• Corporate library
• Growth opportunities
• Cutting-edge frameworks and technologies
• Competitive salary
• Common team activities (football, basketball, tennis, board games, and more)
• 21 paid vacation days & 14 paid sick leaves
• Work-life balance
• Cozy office in Warsaw available for you whenever you need it
• Coffee, tea, sweets, fruits, and more snacks

If you've personally closed senior marketing and creative roles in competitive markets — and you know the difference between "good" and "A-player" when you see it — we'd love to talk.

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.

This role is for an experienced Product Analyst with a strong background in product analytics, experimentation, and data-driven decision-making. You will be responsible for defining product success metrics, analyzing user behavior and A/B test results, uncovering actionable insights, and collaborating cross-functionally to optimize acquisition, retention, and trading experiences while supporting business growth.

• Experience using Python or R (Pandas, SciPy, Jupyter) for deeper statistical analysis, cohort modeling, or predictive analytics
• Proven ability to design and govern product event tracking architecture from scratch

Will be a plus

• Domain knowledge in CFD trading, Crypto exchanges, or traditional brokerage businesses
• Experience with Data Engineering concepts and tools (dbt, Airflow) to build your own data pipelines
• Familiarity with mobile attribution platforms (AppsFlyer, Adjust) and deep-linking analytics
