We build the infrastructure, tools, and model access that teams need to move from idea to production, and do it at scale without compromise. For developers and enterprises, fal is the foundation that makes generative media not just possible, but practical: a unified platform where high-performance inference, orchestration, and observability come together to unlock new categories of AI-native products.\nAs generative media reshapes industries across a market projected to grow by hundreds of billions over the next decade, fal is becoming the ecosystem that ambitious teams build on.\nAbout this role\nThis is a founding role on the small team that owns fal's core product systems - the connected tissue the whole business runs on: usage, billing, pricing, accounts, access, API keys, and model discovery. You'll join early, own these systems end-to-end (from data model through rollout to operational health), and design the APIs and product surfaces other teams and customers depend on. These are backend systems where correctness underpins real revenue and customer trust.\nYou will inherit systems that are functional, but you'll own their evolution over time to meet our growing customer needs and scale. Your first priority will be billing, fraud, and pricing. These are our highest-impact business initiatives, directly affecting both customer experience and revenue. From there, you'll expand your ownership across accounts, access and identity, API keys, and model discovery.\nIf you enjoy building and evolving high-impact platform systems that directly influence both our customers' experience and the effectiveness of our internal teams, this is the place to be.\nWhat you'll do\nOwn billing and pricing first - metering, usage roll-ups, pricing logic, and the customer/admin surfaces that make cost understandable and trustworthy.\n\nDesign APIs, data models, and product contracts other teams safely build on.\n\nGrow into the broader portfolio - accounts, access/identity, API keys, and model discovery - and the surfaces that expose usage, cost, and access.\n\nEngineer for correctness and resilience: source of truth, idempotency, auditability, permissions, observability, graceful failure.\n\nOwn operational health, including on-call for the systems you build.\n\nPartner across product, infra, finance, revenue, security, and customer-facing teams - turning messy, manual workflows into durable systems.\n\nQualifications/Nice to have:\n5+ years building reliable, production backend systems (Python and/or TypeScript).\n\nStrong PostgreSQL - schema design, queries, migrations, performance.\n\nAPI & data-model design for complex product or business domains.\n\nCan ship product and internal surfaces in React / Next.js / TypeScript.\n\nStrong systems judgment (source of truth, idempotency, auditability, permissions, observability) and product judgment (workflows, edge cases, customer trust).\n\nThrives in ambiguous, cross-functional work where product, business logic, and infra overlap; ships a pragmatic v1 that can evolve. Priorities move fast - you're comfortable with that.\n\nUsage-based billing / metering / pricing - Stripe, Orb, Metronome, or similar.\n\nIdentity & access - permissions, SSO, API keys, org/account hierarchy.\n\nDeveloper platforms, model registries, or usage/observability dashboards.\n\nGenerative AI / inference APIs or other developer-facing AI products.\n\nWe use Python (primary backend) · TypeScript + React/Next.js (product surfaces) · PostgreSQL / SQL · with some migration to Rust underway.\n\nWhat fal offers\nInteresting and challenging work\n\nA lot of learning and growth opportunities\n\nWe offer visa sponsorship and will help you relocate to San Francisco.\n\nHealth, dental, and vision insurance (US)\n\nRegular team events and offsites\n\nCompensation\n$180,000 - $250,000 + equity + comprehensive benefits package\n\nU.S. EQUAL EMPLOYMENT OPPORTUNITY INFORMATION:\nfal provides equal employment opportunities to applicants and employees without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, protected veteran status, disability, or any other classification protected by applicable law.","description_format":"text","description_chars":4232,"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":["Equity","Growth opportunities","Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Generative Image","Generative Video","AI Compute & Inference"],"lifecycle":[{"event":"open","at":"2026-07-06T20:38:53Z"}],"visa":[],"liveness":{"score":27,"band":"fade","label":"Fading","p_open":1,"p_active":0.744,"p_room":0.36,"age_days":104,"expected_fill_days":65,"reasons":["conf:3","velocity","win:tail","crowd:"],"computed_at":"2026-10-19T05:45:15Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":false},"html_url":"https://alion.io/job/fal-seniorstaff-software-engineer-core-product-systems","json_url":"https://alion.io/job/fal-seniorstaff-software-engineer-core-product-systems.json","meta":{"generated_at":"2026-10-19T22:43:25Z","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":1625,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-20T00:00:00Z"}},"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":44380},"rest":"https://alion.io/mcp/rest/get_company?id=44380"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffal-seniorstaff-software-engineer-core-product-systems"},{"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%2Ffal-seniorstaff-software-engineer-core-product-systems"},{"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%2Ffal-seniorstaff-software-engineer-core-product-systems"},{"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/fal-seniorstaff-software-engineer-core-product-systems\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffal-seniorstaff-software-engineer-core-product-systems"}]}
