We believe AI is a new medium that allows us to express ourselves through various formats - text, images, video, sound, and even 3D. We're building better, smarter, and more controllable tools to harness this medium. We recently took this a step forward with the launch of Krea 2, our first foundation model, built completely from scratch for aesthetic diversity and stylistic control.\nWe've raised over $83M and are backed by world-class investors such as a16z, Bain Capital, and Abstract. We work full-time and in-person at our waterfront office in San Francisco. We care about creativity: our team includes musicians, designers, visual artists, and engineers.\nWhat you'll do\nYou'll work across the whole backend: the SvelteKit app and its Postgres, Redis, and ClickHouse data layer, the Python services that run our ML inference, and the Kubernetes clusters that tie it together across multiple cloud and GPU providers. You'll own these systems end-to-end, from design through to running them in production.\nA sample of what we're working on right now:\nDurable execution for long-running workflows. Building the state machines, idempotency, and retry semantics that keep multi-step inference jobs correct when they take minutes to finish and anything can fail mid-flight\n\nImproving our public API. Designing a clean, well-documented API surface with OpenAPI docs auto-generated from our Zod schemas\n\nEnterprise product features. ACLs, audit logs, entitlements, and all the \"boring\" features that organizations with a thousand users expect\n\nWhat we're looking for\nWe care more about first-principles engineering than which languages or tools you happen to know\nYou've owned real production systems end-to-end: design, monitoring, metrics, incidents. Ideally you have 4-8 years of experience, but we care about scope and judgment over the number on your resume\n\nYou're comfortable across the stack and unfazed by unfamiliar code, and you have opinions about how to architect things that scale\n\nYou write and talk clearly, and you're happy working without a lot of PM hand-holding\n\nBonus if you: have GPU or infra experience, have run Kubernetes in production, or come from a creative background. A lot of us do, and it helps when you're building tools for creatives (but it's genuinely not a requirement).\nOur stack\nSvelteKit, TypeScript, Python, Postgres (AWS Aurora), Redis, ClickHouse, Docker, Kubernetes, FluxCD.\n\nWhat we offer\nTeam: Work alongside a world-class team building the future of AI creative tooling\n\nImpact: Significant scope and company-wide impact\n\nCompetitive compensation: generous salary & equity packages\n\nHealth & wellness: 100% health & 99% dental/vision insurance premiums covered for employees, health FSA accounts, & long-term disability coverage\n\nTime off: Flexible PTO policy\n\nFinancial planning: 401k with a 4% company-sponsored match\n\nMeals in the office: breakfast, lunch, dinner - you name it, we'll cover it\n\nTransit: Ubers covered to & from the office\n\nSponsorship: We're open to sponsoring international visas where we can (e.g., STEM OPT, OPT, H-1B, O-1, E-3).\n\nAnd more!\n\nPlease note the above benefits & perks are for full-time employees","description_format":"text","description_chars":3397,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["401k plan","Equity","Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Generative Image"],"lifecycle":[{"event":"open","at":"2026-08-04T22:54:59Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 1","filings_12m":1,"filings_prev_12m":4,"green_card_filings_12m":0,"median_offered_wage_usd":107500,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.177,"p_room":0.28,"age_days":72,"expected_fill_days":23,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/krea-software-engineer-backend","json_url":"https://alion.io/job/krea-software-engineer-backend.json","meta":{"generated_at":"2026-10-16T15:56:11Z","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":291,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":48104},"rest":"https://alion.io/mcp/rest/get_company?id=48104"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fkrea-software-engineer-backend"},{"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%2Fkrea-software-engineer-backend"},{"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%2Fkrea-software-engineer-backend"},{"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/krea-software-engineer-backend\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fkrea-software-engineer-backend"}]}
