We are building open frontier AI: open-source models trained end to end for long-horizon tasks like autonomous research, and the full-stack platform our own research team uses to build them. The next generation of AI companies, enterprises, and research teams do not just need more GPUs. They need the ability to turn their own workflows, tools, data, and feedback loops into superintelligence they own.\nPrime Intellect has raised $150M in total funding from Founders Fund, Radical Ventures, NVIDIA, and exceptional AI, infrastructure, and enterprise operators - including Andrej Karpathy, Dwarkesh Patel, and leaders and founders from Ramp, Perplexity, Harvey, Mercor, Zapier, Datadog, Cognition, OpenAI, Thinking Machines, Together AI, SemiAnalysis, LangChain, Browserbase, Cloudflare, Sierra, Databricks, Airbnb, OpenRouter, Standard Intelligence, Fleet, Core Auto, and more. We are looking for people who want to build at the intersection of frontier research, real infrastructure, and go-to-market for a category that does not fully exist yet.\nRole Impact\nThis is a generalist software engineering role focused on building the product surface of Prime Intellect - the developer-facing platform, APIs, and services that researchers and engineers around the world use to train and deploy frontier models. You'll own features end-to-end, from design through deployment and monitoring, and ship at the pace of an early-stage company tackling one of the most important problems in AI.\nCore Responsibilities\nBuild intuitive web interfaces for AI workload management and monitoring\n\nDevelop REST APIs and backend services in Python\n\nOwn features end-to-end, from design through deployment and operation\n\nCreate real-time monitoring and debugging tools for users of the platform\n\nImplement user-facing features for resource management and job control\n\nDeploy and operate services on cloud infrastructure\n\nContribute to internal tooling, automation, and developer experience improvements\n\nTechnical Requirements\nStrong Python backend development (FastAPI, async)\n\nModern frontend development (TypeScript, React/Next.js, Tailwind)\n\nExperience building developer tools, dashboards, or platform products\n\nRESTful API design and implementation\n\nComfortable working with cloud platforms (GCP a plus) and containerized deployments\n\nA bias toward shipping, ownership of production code, and pragmatic engineering judgment\n\nInfrastructure automation experience (Ansible, Terraform, Kubernetes)\n\nNice to Have\nInterest in or exposure to ML/AI workloads\n\nWebSocket / real-time systems experience\n\nOpen-source contributions\n\nObservability tooling (Prometheus, Grafana)\n\nPrior experience at an early-stage startup\n\nWhat We Offer\nCash compensation range of $150-300k with significant equity incentives\n\nFlexible work arrangement (remote or San Francisco office)\n\nFull visa sponsorship and relocation support\n\nProfessional development budget for courses and conferences\n\nRegular team off-sites and conference attendance\n\nOpportunity to shape the future of open AI development\n\nGrowth Opportunity\nYou'll join a team of experienced engineers and researchers working on cutting-edge problems in AI infrastructure. We believe in open development and encourage team members to contribute to the broader AI community through research and open-source contributions.\nWe value potential over perfection - if you're a strong generalist engineer who is passionate about democratizing AI development, we want to talk to you.\nReady to help shape the future of AI? Apply now and join us in our mission to make powerful AI models accessible to everyone.","description_format":"text","description_chars":4080,"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":["Equity","Flexible schedule","Professional development"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Reinforcement Learning","Foundation Models","AI Compute & Inference","AI Development Tools"],"lifecycle":[{"event":"open","at":"2026-07-08T18:45:08Z"},{"event":"close","at":"2026-10-21T12:02:28Z"}],"visa":[],"liveness":null,"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/primeintellect-member-of-technical-staff-full-stack-software-engineer","json_url":"https://alion.io/job/primeintellect-member-of-technical-staff-full-stack-software-engineer.json","meta":{"generated_at":"2026-10-22T23:24:14Z","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":9152,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-23T00:00:00Z"}},"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":5907},"rest":"https://alion.io/mcp/rest/get_company?id=5907"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fprimeintellect-member-of-technical-staff-full-stack-software-engineer"},{"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%2Fprimeintellect-member-of-technical-staff-full-stack-software-engineer"},{"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%2Fprimeintellect-member-of-technical-staff-full-stack-software-engineer"},{"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/primeintellect-member-of-technical-staff-full-stack-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fprimeintellect-member-of-technical-staff-full-stack-software-engineer"}]}
