Full-Stack Product Engineer — TypeScript, AI, Telemetry

🏁 Take a Seat on the Pit Wall

At RACEMAKE, we aren't just building another AI analytics dashboard. We are revolutionizing how sim racers and real-world drivers spend their off-track time. Our mission is clear: Turn data into on-track speed.

We are looking for an engineer who isn't afraid to look "under the hood." Our stack runs on modern TypeScript — from a Next.js web app to a Bun/Hono API powering AI coaching — with telemetry flowing in from simulators like Le Mans Ultimate, iRacing, and Assetto Corsa Competizione.

Our small team designed the core architecture — the data pipeline, the native agent, the telemetry stack. We need someone to take the architecture and build on it. Fast.

🎯 Your Mission

Your job won't be changing button colors in React. Your playground is telemetry pipelines, AI coaching prompts, and full-stack features that make drivers faster.

• Feature Development: You ship across the entire stack — lap analysis UI in React, new API endpoints in Bun/Hono, coaching logic powered by LLMs.
• AI Coaching: You tune system prompts and tool-use patterns so PitGPT gives better corner-by-corner advice for GT3 and LMdh cars.
• Sim Integration: When a game update changes telemetry formats overnight, you trace the issue and ship the fix before anyone notices.
• Debugging: Something breaks in production — you check logs, find the cause, fix it. Not a thread about it.

🛠️ Tech Stack & Skills

We are looking for a mid-level or senior engineer who can ship on our existing stack from day one.

• TypeScript / React / Next.js: You build UI and API without switching gears. You're fast.
• Bun, Hono, ClickHouse, Protobuf, Zod: Our backend isn't Express + Postgres. You're comfortable picking up unfamiliar tools.
• Passive Rust: You don't need to write our Tauri agent from scratch, but you can read our CTO's code and extend it with AI assistance.
• AI-Native: Cursor, Claude, Copilot — you use AI to move fast, but you catch it when it hallucinates. The fundamentals matter.

🚀 What We Offer

We are not a bank or a corporation. We are a startup with the ambition to move from virtual tracks to real ones. We are demanding, we push for results and communication, and we want drive and ownership from you. In return, we offer:

• Maximum Freedom: No micromanagement. We care about working, optimized code, not hours logged.
• Access to Motorsport: Opportunities to participate in tests and real-world races. • Equity: Available for top candidates — milestone-based, earned through impact.
• Contract or Full-Time: Up to €60/hr. We pay for speed and autonomy.
• Remote-First: Work from your home office or our office in Prague.
