This superlearning capability - the ability to endlessly discover knowledge and skills, without relying on human data - will be driven by the world’s most powerful reinforcement learning algorithms.\nThe superlearner is expected to rediscover and then transcend the greatest inventions in human history, such as language, science, mathematics and technology. If successful, this will represent a scientific breakthrough of comparable magnitude to Darwin: where his law explained all life, our law will explain and build all intelligence.\nRole brief\nIntelligence cannot emerge in a void. It needs a place to grow and flourish. As a Simulated Universes Engineer, you’ll help us craft, shape and maintain the worlds in which superlearners can emerge and thrive. That means making those worlds accurate, reliable and intricate, and scaling them to unprecedented highs in terms of both parallelism and speed. It’s a challenging quest and one that’s critical to our mission. In this role, you will:\nBuild the engineering foundations of our new environments; designing, implementing and maintaining them as they grow\n\nPartner closely with the team creating the blueprints for the worlds we need to build\n\nClose the loop between blueprint and build, enabling fast, iterative research cycles\n\nScale the environments up, while utilising state-of-the-art hardware\n\nAbout you\nYou’re an engineer with a passion for creating artificial worlds, and you know what it takes to make them emerge at scale. You may be a good fit if you:\nBring industry experience with large-scale simulations, whether in demanding scientific domains or in the games industry\n\nKnow how to build systems like huge distributed MMOs that rely on world parallelism, large-scale physics engines, or logic that preserves consistency despite decentralised computation\n\nTurn ambitious research visions into reality by designing, building and maintaining codebases that support fast research iteration and efficient execution\n\nEnjoy working closely with researchers and/or \"designers\", taking their blueprints and turning them into worlds that agents can explore and learn\n\nOn the pure engineering side, you’ll likely have experience with the following:\nPhysics engines\n\nGPU-accelerated physics and simulation frameworks, such as NVIDIA Warp\n\nLower level languages such as Rust, C or C++\n\nImplementation of distributed server-client architectures\n\nWriting efficient GPU code\n\nWe move fast, give people real ownership and trust engineers to make good judgment calls. We are a team that cares as much about doing this well as doing it fast.\nIf you're interested in joining Ineffable and think your skills would be better suited to a different position please explore the careers page for other opportunities.","description_format":"text","description_chars":2981,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Research Labs"],"lifecycle":[{"event":"open","at":"2026-09-24T08:08:34Z"}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.858,"p_room":1,"age_days":7,"expected_fill_days":36,"reasons":["conf:7","win:early"],"computed_at":"2026-10-01T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/ineffable-intelligence-software-engineer-simulated-universes","json_url":"https://alion.io/job/ineffable-intelligence-software-engineer-simulated-universes.json","meta":{"generated_at":"2026-10-01T11:19:28Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":2906,"day_limit":5000,"remaining_today":2094,"minute_limit":60,"resets_at":"2026-10-02T00:00:00Z"}}}
