Our flagship product, Genesis World, is a unified multi-physics simulation engine paired with Nyx, our in-house GPU-accelerated, path-traced photorealistic renderer. Together they provide a platform for training robotics and embodied AI at scale; letting teams simulate complex physical worlds with high fidelity and speed, from a laptop to datacenter-grade GPUs, and close the gap between simulation and the real world.\nAbout the Role\nWe're hiring a Senior QA Engineer to own quality across Nyx and the Genesis World engines. You'll split your time evenly between hands-on exploratory testing and enhancing our automated test infrastructure. Because both systems run on GPUs and underpin robotics training and scientific workloads, correctness goes beyond \"does it run\": it's about visual fidelity, numerical accuracy, determinism, and reproducibility across hardware.\nWe're especially looking for someone with strong knowledge of 3D environments, assets, and rendering, who can reason about what \"visually and physically correct\" actually means.\nWhat You'll Do\nMaintain and evolve our automated test suites for the Nyx renderer and the Genesis World physics engine.\n\nDevelop image-comparison / perceptual-diff tooling to catch rendering regressions, and validation harnesses to catch simulation drift.\n\nValidate numerical correctness, determinism, and reproducibility across GPUs, drivers, and CUDA versions.\n\nPerform exploratory and manual testing on 3D scenes, assets, and complex multi-physics scenarios that are hard to automate.\n\nSet up quality gates in CI for prebuilt wheels across platforms (Linux, Windows, Python 3.10-3.13).\n\nTriage, reproduce, and clearly document defects; partner with engineers on root cause.\n\nWhat We're Looking For\n5+ years in software QA, with strong experience in both test automation and exploratory testing.\n\nSolid 3D environment and asset knowledge, with familiarity with rendering and simulation/physics.\n\nStrong Python and C++ skills; comfortable reading performance-sensitive code.\n\nUnderstanding of testing challenges in GPU and floating-point systems; non-determinism, tolerance-based assertions, hardware/driver variance.\n\nExperience building test infrastructure in CI/CD and managing cross-platform builds.\n\nExcellent debugging instincts and clear, reproducible bug reports.\n\nNice to Have\nExperience with GPU programming, or ray/path tracing concepts.\n\nBackground in computer graphics (PBR, color management, perceptual image metrics).\n\nFamiliarity with physics or scientific simulation.\n\nRobotics or sim-to-real experience.","description_format":"text","description_chars":2687,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"France","iso":"FR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-26T03:16:02Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.256,"p_room":0.28,"age_days":134,"expected_fill_days":35,"reasons":["conf:2","stale_co","win:tail","crowd:"],"computed_at":"2026-10-29T05:49:05Z"},"pay":null,"html_url":"https://alion.io/job/genesis-ai-qa-engineer-nyx-renderer-genesis-world","json_url":"https://alion.io/job/genesis-ai-qa-engineer-nyx-renderer-genesis-world.json","meta":{"generated_at":"2026-10-29T06:53:21Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":10409,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":1908459},"rest":"https://alion.io/mcp/rest/get_company?id=1908459"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fgenesis-ai-qa-engineer-nyx-renderer-genesis-world"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fgenesis-ai-qa-engineer-nyx-renderer-genesis-world"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fgenesis-ai-qa-engineer-nyx-renderer-genesis-world"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/genesis-ai-qa-engineer-nyx-renderer-genesis-world\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fgenesis-ai-qa-engineer-nyx-renderer-genesis-world"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3258742}},{"tool":"search_jobs","arguments":{"company":"genesis.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3258742},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people);
