QA Engineer San Francisco & Paris
Tryarcade, Mission, KS, United States
QA Engineer — Engine Reliability & Bug Fixing
Paris & San Francisco (Remote / Hybrid)
Contract: 2-Month Freelance Mission (Path to Full-time Founding Engineer)
The Mission
Your role is simple: find every bug, understand it deeply, and fix it fast.
If this mission is a success, the goal is to convert this into a full-time Founding Engineer role.
What you'll do
Break the system relentlessly: Design and execute aggressive testing strategies to uncover edge cases, inconsistencies, and failures across the entire pipeline (LLMs → DSL → 3D engine).
Own bug fixing end-to-end: Identify, reproduce, debug, and fix issues directly in the codebase — not just report them.
Build testing infrastructure: Create automated test suites, validation pipelines, and regression systems to ensure stability as we iterate fast.
Test AI-driven systems: Validate outputs from LLMs (Claude, Gemini), ensuring consistency, determinism, and correctness when translated into game logic and 3D environments.
Stress test agentic workflows: Push multi-agent systems to their limits, identify failure modes, and harden the system against unpredictable behaviors.
Collaborate tightly with engineers: Work side-by-side with AI and 3D engineers to quickly diagnose issues and ship fixes in real time.
Improve product quality at speed: Ensure we can ship fast without breaking everything.
You might be a fit if...
You have a strong track record in QA or engineering roles where you owned product reliability and stability.
You are obsessed with edge cases, weird bugs, and breaking systems.
You have experience testing complex systems (APIs, AI systems, game engines, or distributed systems).
You are comfortable working with AI outputs and understand their non-deterministic nature.
You know how to build automated tests (unit, integration, end-to-end).
You move fast, think clearly under pressure, and prioritize impact over perfection.
Your personal workflow is highly technical and AI-augmented.
Language: You are perfectly fluent in English (written and spoken).
What we offer
The Mission Setup: A highly competitive freelance rate for the initial 2-month contract.
The Path to Founding Engineer: If we\'re a great match, you\'ll transition to a full-time role with Founding team equity — build and own a piece of what you create.
Impact: A defining role in building a system that could change how games are created worldwide.
Extreme Ownership: You don\'t just test — you ensure the system works.
Talent & Culture: Work with A-players in an AI-native team that ships fast, breaks things, fixes them, and keeps going.
