It delivers up to 7x faster output token speed, up to 90% lower inference costs, and 99.99% uptime across the most demanding agent workloads - long-context inference, real-time streaming, and accurate tool calling.\nWe are a small, fast-moving team doing work that matters at one of the most exciting moments in the history of technology. With our world-class inference stack, we are building the platform teams can actually rely on.\nAbout the Role\nWe're seeking a Full-Stack Software Engineer to design, build, and scale our web platform, which serves as the core interface for deploying multimodal models, observing workloads, and building agent workflows. You'll own how customers experience the platform end-to-end- signing up, authenticating, managing access across an organization, and understanding what they're being billed for - from the services and data models through to the interface. In this role, you'll work closely with product, infrastructure, and design teams to create high-performance, developer-friendly, and enterprise-ready tools.\nWe are looking for a hands-on engineer who is eager to work across the surfaces of our application - authentication and access control, billing and usage, and the model deployment and inference features customers use every day. The ideal candidate has built backend systems where correctness matters, is comfortable carrying a feature all the way to the UI, cares deeply about developer workflows, and is excited to help define the future of AI adoption.\nKey Responsibilities\nDesign, build, and maintain web applications and tools for AI model deployment, monitoring, and performance optimization\n\nOwn authentication, organization management, and billing end-to-end.\n\nDevelop clean, scalable, and robust APIs powering AI agents, workflows, and user-facing systems\n\nCollaborate with infrastructure engineers to integrate backend systems with deployment and orchestration pipelines\n\nDrive code quality through automated testing, CI/CD, and code reviews\n\nContribute to architecture and design decisions that shape our platform's long-term direction\n\nIdentify and resolve technical debt and improve system reliability in production systems\n\nQualifications\n4+ years of industry experience in backend or full-stack engineering, with meaningful time spent on backend systems\n\nBachelor's or Master's degree in Computer Science, Computer Engineering, or equivalent\n\nProduction experience with authentication and authorization - SSO/OAuth2/OIDC, RBAC, API keys, and multi-tenant isolation\n\nExperience building billing or usage-metering systems: usage-based or subscription pricing, entitlements, quotas, or payment integration\n\nFluent in Python and TypeScript; proficient with React/Next.js\n\nStrong backend experience with FastAPI or similar Python frameworks\n\nProficiency in designing data models, writing SQL, and working with PostgreSQL; familiarity with OLAP systems such as ClickHouse\n\nStrong API design experience across gRPC/REST/GraphQL in production systems\n\nSolid foundation in cloud-native development\n\nFamiliarity with OpenTelemetry tracing, metrics, and structured logging\n\nPreferred Experience\nExperience with payment processors (e.g., Stripe) and usage-based or subscription SaaS billing\n\nFamiliarity with enterprise identity requirements - SAML, SCIM provisioning, or providers like Auth0/WorkOS\n\nFamiliarity with LLM-based workflows, tool invocation, or agentic systems\n\nFamiliarity with Kubernetes for container orchestration, including deploying, scaling, and managing containerized applications in production environments\n\nHave worked in a startup or fast-paced environment with ownership\n\nBuilt developer-facing SDKs/CLIs\n\nPassion for developer experience and enabling AI adoption\n\nBenefits\nFlexible working hours\n\nDaily lunch and dinner provided; unlimited snacks and beverages\n\nSupportive and highly collaborative work environment\n\nHealth check-up support and top-tier equipment/hardware support\n\nA front-row seat to the generative AI infrastructure revolution\n\nCompetitive compensation, startup equity, health insurance, and other benefits.","description_format":"text","description_chars":4244,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity","Flexible schedule","Health insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","LLM & Generative AI","AI Agents"],"lifecycle":[{"event":"open","at":"2026-09-10T23:15:26Z"}],"visa":[],"liveness":{"score":9,"band":"cold","label":"Long shot","p_open":1,"p_active":0.333,"p_room":0.28,"age_days":73,"expected_fill_days":30,"reasons":["conf:2","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/friendli-software-engineer-full-stack","json_url":"https://alion.io/job/friendli-software-engineer-full-stack.json","meta":{"generated_at":"2026-10-31T08:12:52Z","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":12192,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":673295},"rest":"https://alion.io/mcp/rest/get_company?id=673295"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffriendli-software-engineer-full-stack"},{"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%2Ffriendli-software-engineer-full-stack"},{"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%2Ffriendli-software-engineer-full-stack"},{"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/friendli-software-engineer-full-stack\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffriendli-software-engineer-full-stack"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":678887}},{"tool":"search_jobs","arguments":{"company":"friendli.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":678887},"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);
