About the project
 

US-founded media company operating email newsletters at scale – millions of subscribers across finance, health, and business verticals. Small engineering team, flat structure, direct ownership, fast iteration. No layers of approval, no large org to navigate.

You'll own the AI layer of the automation platform alongside a counterpart engineer who handles integration and infrastructure.
 

What you'll work on

• AI-driven content generation and management workflows at production scale
• Agent systems coordinating multi-step operational tasks: content, QA, validation, reporting
• RAG pipelines over internal knowledge bases and operational data
• Prompt architectures designed for reliability, cost control, and measurable output quality
• Evaluation and regression testing for LLM systems — "it looked fine when I tested it" isn't good enough
   

Real production systems, not demos. The work removes hours of manual operational work daily and needs to be reliable enough that people actually trust it.
 

Requirements

• 6+ years of development experience
• 4+ years of production Python
• 2+ years shipping production systems with LLMs and agents
• Solid understanding of what happens underneath the frameworks: tokenization, context windows, function calling, when RAG helps and when it doesn't
• Hands-on with agent orchestration: LangChain, LangGraph, MCP, or equivalent
• Clean, maintainable Python – frameworks support your thinking, not replace it
   

Tech stack

Python · FastAPI · PostgreSQL · LLM APIs (OpenAI, Anthropic) · LangChain / LangGraph / MCP · vector databases · Playwright · Docker · proxy infrastructure
 

Conditions

• B2B contract, full-time
• Warsaw office (onsite preferred, remote considered)
• Direct collaboration with technical PM and small senior team
• Fast-moving environment: ambiguity, shifting priorities, growing scope

About WOWCube

At WOWCube®, we’re redefining play with a one-of-a-kind cube-shaped gaming console that merges the physical and digital worlds. 

The WOWCube Entertainment System combines modular hardware, immersive software, and creative game design to create a brand-new category of interactive entertainment.

About the Role

We are looking for a hands-on Game Designer to shape core mechanics, design levels, and turn ideas into playable experiences alongside the team.

You will design puzzles, systems, and progression at every stage, from first sketch through documentation to shipped feature, working in tight cooperation with developers, artists, and animators.

We expect a designer who thinks in systems and player experience, communicates through clear documentation, and drives decisions backed by playtests and data.

What You’ll Do

• Design, document, and refine core gameplay mechanics, progression systems, and game economy.
• Drive rapid prototyping in close collaboration with developers: shaping interactions, validating mechanics, and iterating on playable builds.
• Create and iterate on levels, puzzles, and gameplay challenges that are fun, logical, and intuitive.
• Prepare clear, concise design documentation for the core loop and meta systems.
• Define an MVP scope for each new idea so it can be prototyped and validated fast, before the team commits to full production.
• Build configuration systems that give you full control over game feel and keep the design coherent and easy to tune as the project grows.
• Define clear asset requirements for artists and animators, making sure assets are exported correctly and ready for integration into builds.

Requirements

• Minimum 3 years of professional experience as a Game Designer.
• 1–3 shipped products (mobile titles at least in soft launch, or released PC games).
• Strong command of technical game design documentation, game balancing, and day-to-day work in Jira and Confluence.
• Comfortable in a highly iterative R&D environment, working in close cooperation with developers.
• Hands-on experience with Figma, including active collaboration with artists and other designers inside the tool.
• Experience working with AI pipelines (e.g., generating concepts via image/video generation).
• Examples of original levels or puzzles with a clear explanation of the design intent and why they work.
• Ability to produce short, structured, and clear design specs.
• Openness to iteration and user testing.

Nice-to-Haves

• Experience in casual or puzzle game development.
• Experience designing onboarding, tutorials, and dynamic difficulty.
• Basic 2D/3D art skills (greyboxing, concept sketches, simple sprites or models).
• Ability to prototype full gameplay mechanics with AI assistance, not just visually.
• UI/UX design experience with visual prototyping in Figma.

What We’d Like to See in Your Application

• 1–2 game design documents from your portfolio of shipped games.
• 2–3 links to shipped games (videos of those games are also welcome).
