• A stable full-time role in a growing international business

The role

We're looking for a part-time strategy analyst to support live client engagements. You'll work with our technical team that builds an AI platform for strategic simulations and scenario modeling.
 

Right now the focus is on Ukrainian clients. That's your entry point. We work with companies in energy, oil and gas, commodities, chemicals, manufacturing and retail. Over time we'll connect you to global projects: corporate development, M&A, strategic planning for international clients.
 

Your job is to validate AI simulation outputs, build financial models, analyze what data is available on the client side and in the market, and turn raw platform results into materials that executives use to make decisions.
 

Part-time, 10-20 hours per week. Flexible schedule. Hours can scale up as we take on more clients.
 

What you'll do

1/ Validate AI simulation results against real market data and financials. You're the reality check between the AI and the client
2/ Build financial models that connect to the simulation platform. Scenario analysis, stress-testing, forecasting
3/ Audit available data on the client side. What exists, what's missing, what's reliable, what needs additional verification
4/ Market sizing, competitive analysis, industry benchmarking for active engagements
5/ Source and structure Ukrainian market data (harder to find than US/EU, which is exactly why we need you)
6/ QA models and deliverables for accuracy and industry relevance before they go to the client
7/ Prepare client-facing materials: presentations, analytical memos, executive summaries
 

Requirements

• Domain experience in energy, oil and gas, commodities, chemicals, manufacturing or retail. You've worked in one or more of these industries and understand their specifics, key metrics and how data is structured
• 2+ years at a Big Four firm (Deloitte, PwC, EY, KPMG) in consulting, audit or transaction advisory, a strategy consultancy or in an analytical/financial role at a corporation. Audit experience with Ukrainian corporates is a strong plus -- you already know what data actually exists and what doesn't.
• Financial modeling skills. You can build models from scratch in Excel/Google Sheets, not just fill in templates
• Experience structuring and presenting data for senior executives
• Comfortable working with large, unstructured datasets and extracting signal from noise
• Can work independently. We give you the project context and you run with it
• Ukrainian -- fluent
• English -- B2+. Team communication and internal deliverables are in English
   

Big plus

• Experience with M&A due diligence, transaction advisory or corporate development
• Market sizing, competitive benchmarking, industry landscape analysis
• Familiarity with AI tools (Claude, ChatGPT, Cursor or similar) for research and analysis acceleration
• Experience with scenario planning, simulations or wargaming
• Worked at a startup or fast-moving team where you covered multiple roles at once
• Accounting, audit or financial reporting background

Not for you if

• You need a detailed brief before you start working. We move fast and fill in gaps as we go
• You only know how to execute within pre-built frameworks. We need people who build the framework
• You've only done advisory and never built the models yourself
• You're looking for a strict 9-to-5
   

Compensation

• Hourly rate, discussed individually based on experience
• Part-time contract, 10-20 hours per week
• Potential to scale hours or convert to ongoing retainer as engagements grow
   

We review every application and reply only to candidates who are a strong fit. If you don't hear back within two weeks, the role wasn't the right match this time.

• Systems depth: C++/Rust/Scala/Java, performance/infra optimization, distributed systems.
• Exposure to RL / bandits / agentic systems (not required, but a strong signal).
   

Not a fit if

• You’re primarily a prompt engineer without strong ML/engineering foundations.
• You’re a research-only / academic-only profile with little or no shipping/production ownership.
• You’ve only built in notebooks or rely heavily on managed AutoML tools.
  
   

Working Conditions
