Our goals:

• Break into the global top 5 product companies.

• Make Ukraine a country where unicorns are born.

We’re looking for bold, driven people who are passionate about building real products and dream of launching and scaling great startups. You bring the ambition — we provide the environment to make it happen.
 

What you’ll do:

• Design and develop an AI-powered productivity analytics platform — from data pipeline architecture to the final analytical product that helps teams make data-driven decisions.
• Build scalable LLM pipelines (Claude, GPT): develop data chunking strategies, implement MapReduce approaches for parallel processing of large datasets, and synthesize results into structured reports and insights.
• Create a meta-workflow system where LLMs generate, test, and deploy automation scripts in an isolated environment — with automatic self-correction loops and production deployment without manual intervention.
• Develop system-level prompt engineering: build and maintain a library of prompt templates for various analytical scenarios — from summaries and profiles to deep performance analysis.
• Build an evaluation framework for AI output quality control: hallucination detection, consistency scoring, regression tests — ensuring the product delivers reliable and reproducible results.
• Scale the platform to new domains and analysis types without linear growth in manual effort — through an architecture that allows adding new modules via configuration, not code.
• Document AI architecture, define automation specs, and present product insights to stakeholders and clients.
   

It’s a match if you have:

• Strong Python skills (async, dataclasses, type hints, API integrations) and a commitment to writing clean, testable, and maintainable code.
• Understanding of MapReduce patterns for LLM processing: ability to choose chunking strategies, organize parallel processing, and aggregate results into a cohesive analytical product.
• Experience building agentic systems: tool use, self-correcting loops, multi-agent workflows — and the judgment to know when an agent works better than a rigid pipeline.
• Proficiency in SQL and experience working with analytical databases.
• English at C1 level — comfortable reading documentation, writing technical specs, and communicating asynchronously.
• Ownership mentality: you take tasks end-to-end, debug production issues independently, and iterate to deliver results without micromanagement.
   

Nice to have:

• Experience with orchestration/automation platforms (Windmill, Dagster, Prefect) — understanding how to build reliable automated workflows.
• Knowledge of RAG architectures, vector databases, and embedding pipelines — ability to build systems that work with large volumes of unstructured data.
• Experience building evaluation systems for LLMs (LangSmith, PromptFoo, or custom solutions) — understanding how to measure and improve AI product quality.
• Familiarity with Databricks / Delta Lake or Snowflake — experience working with modern data platforms.
• Experience working at product-driven tech companies or AI startups where you needed to build and iterate quickly.
• Understanding of product team metrics (DAU, retention, unit economics) and the ability to connect technical decisions to product impact.
   

Preferred tech stack:

Core:

• Languages: Python (primary), SQL
• LLM APIs: Claude API (Anthropic), OpenAI API

For a candidate who consistently exceeds goals, scales their approach, and takes ownership, there is a possibility of having a fast career track to Creative Marketing Director within the first year.
 

What will you do:

• Research the performance advertising market and dig deep into audience pain points, triggers, and motivations

• Use AI tools for analysis, ideation, and visual generation
• Write clear, actionable briefs for designers and elevate production quality
• Work directly with the UA Manager and iterate on creatives quickly

About you:

• You have 1+ years of experience as a Creative Marketing Manager in a B2C digital product

• You have strong skills in writing, converting scripts, and scroll-stopping hooks
• You understand visual storytelling and composition
• You can write clear technical briefs for designers and production teams
• You know how to craft ideas and messages that stop the scroll and generate high product interest
• You want to grow into leadership and take ownership of results
• English - B2+ level
   

Would be a plus if you:

• Have experience growing subscription-based products (not just installs or purchases).
• Worked on funnel conversion and product-side CRO together with the product marketing manager.
• Understand ad tracking systems like Pixel and CAPI, and how events flow into your analytics stack.
• Are comfortable testing from scratch — without perfect data, CRM, or ready-made landing pages.
   

What we offer:

• Real impact: minimum bureaucracy, maximum freedom to test hypotheses
• Fast growth: path to Creative Marketing Director within the first year
• Office & Remote: Offices in Kyiv and Warsaw — hybrid format (3 days/week in office). Remote work is also welcome.
