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.

Experience designing mobile or puzzle games is highly valued, as is a background in games for handheld consoles and other portable gaming devices.

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).

Reports to: Embedded Systems Engineering Manager 
Level: Senior (a strong middle+ with the right depth is welcome)

About WOWCube

WOWCube is a gaming console shaped as a puzzle cube: eight modules with 24 screens that act as one device. We build the hardware, our own operating system (OctaviOS), the system apps and the dock station. The current cube is shipping, the next generation is in bring-up. 

About the role

You will join the embedded team and own whole subsystems of OctaviOS - from design to a release proven on real devices. AI coding agents are part of our everyday toolset and write a large share of the code; the engineer owns the design, keeps the codebase free of technical debt and is responsible for the solution working completely. That means deliberate development with full control over what the agents produce. We are looking for an engineer who turns this way of working into a multiple of a conventional developer's output and works well with the team.

Main responsibilities

• Design, implement and debug C firmware for an ARM Cortex-M / RTOS platform: drivers, system modules, connectivity, power management etc.
• Own features and fixes end-to-end: requirements, design, implementation, tests, verification on devices, release.
• Bring up new board revisions and build the diagnostics for hardware testing.
• Find root causes of crashes, memory corruption, timing and radio issues; prove fixes on hardware.
• Use AI coding agents daily and keep them under control: prepare the context (architecture, hardware constraints, coding rules), review every change for correctness, reuse and size, improve the shared agent setup.

• Review colleagues' work, keep design notes and tests current.

   

Requirements

• 5+ years of firmware development; at least one shipped consumer device.
• Strong C (working C++) on ARM Cortex-M with an RTOS; comfortable with schematics, datasheets, a debugger and a logic analyzer.
• Solid low-level knowledge: memory layout, DMA and caches, interrupts and timing, power management, a radio stack (BLE or similar), serial protocols.
• Experience bringing up a new board and validating firmware on physical devices.
• Systems thinking and a disciplined approach to debugging: reproduce, measure, prove - and the judgment to know when that rigour is needed and when a quick fix is right.
• Daily use of AI coding agents (Claude Code or similar) in real projects, with the judgment to tell good generated code from plausible-looking bad code and the discipline to keep generated changes small, reusable and debt-free.

• A team player: argues with evidence, accepts decisions once made, communicates clearly in writing, flags risks early.

   

Nice-to-Have

• Python for tooling and test automation.
• Vendor SDK bring-up on a less-documented SoC; RTOS internals.
• 2D graphics or game-engine work on constrained hardware.
• Hardware-in-the-loop or factory test rigs; EVT/DVT/PVT experience.

• Rust, MQTT, battery chargers and gauges.

   

How we work

• Small PRs, host tests and CI on every push; a short design note for every mechanism; zero technical debt.
• A bench (cube and dock) at your desk; tooling to flash, install and read telemetry remotely.
• English for code and documentation; remote, async-friendly, EU hours.
