While our core engineering team scales what works, we need someone to figure out what's next. If you love building prototypes that become products, pushing the boundaries of what AI agents can do, and shipping experiments that change the roadmap, we should talk.\n\nBackground\n\nBefore you can move money or open an account, someone has to make sure you're not a criminal. That's compliance, and it's broken.\n\nSphinx builds AI analysts that work inside browsers, APIs, and internal systems just like humans – automating AML, KYC, KYB, and transaction monitoring end-to-end.\n\nOur agents already handle millions of compliance decisions across banking, fintech, and crypto. But what they can do today is a fraction of what's possible. We need someone whose entire job is to explore that gap – building new agent capabilities, prototyping new product surfaces, and turning \"what if\" into \"ship it.\"\n\nWhy Join Sphinx\n\nYou'll build the features that define the product: Every product has a backlog of \"we should build that.\" Your job is to pick the best ones, prototype them, and turn them into features customers love. The ideas are everywhere – from customer conversations, from the team, from you.\n\nWe have never lost a deal to a competitor: Yes you heard that right, we've won every RFP we've been in. The product works – your job is to make it do things nobody's seen before.\n\nYour prototypes become products: This isn't a research lab where things die in a notebook. When your experiments work, they ship to real banks handling real money. The feedback loop is weeks, not years.\n\nHard tech: We're going from zero to one; our tech is our moat.\n\nSmall team, big surface area: Our co-founders previously sold an AI company & have built ML systems that scaled to millions of users and closed deals with major banks. The rest of our team in SF includes PhDs, industry experts, and competitive coders.\n\nZero startup bullshit: We're not chasing investors, we're chasing customers. We're trusted by leading banks and fintechs across the U.S., Canada, Europe, and LatAm. They've seen 90% less manual work, 4× lower costs.\n\nWhat You'll Work On\n\nBuild new product features from scratch. We have a long list of ideas that could become core products – from customer requests, from the team, and from watching how compliance actually works. You'll pick the highest-leverage ones, prototype them fast, and turn them into features that expand what Sphinx can do.\n\nOwn the full stack. You'll design, build, and ship end-to-end: frontend interfaces, backend systems, AI integrations, and everything in between. You're not handing off a spec - you're handing off a working product.\n\nMove between product and engineering fluidly. You'll talk to customers to understand their pain, prototype solutions, test with real users, and iterate until it's right. You think like a PM and build like an engineer.\n\nFeed the roadmap. Your experiments will shape what Sphinx builds next. You'll work closely with the CEO and core engineering team to decide which bets to double down on and which to shelve.\n\nWhat We Look For\n\nYou're deeply technical: You have strong fundamentals in software engineering and a working knowledge of ML/AI systems. You're comfortable building end-to-end (backend, frontend, model integration, infra) whatever the experiment requires.\n\nYou build fast and learn faster: You can go from idea to working prototype in days, not weeks. You're comfortable throwing things away when they don't work and doubling down when they do.\n\nYou have product instincts: You don't just build what's technically interesting – you build what's useful. You think about the user, the workflow, and the problem before writing a line of code.\n\nYou're creative and opinionated: You have strong ideas about what AI agents should be able to do and how people should interact with them. You bring new ideas to the table, not just execute on existing ones.\n\nYou ship and iterate: You'd rather put something imperfect in front of users than spend weeks perfecting it in isolation. You learn from real feedback, not assumptions.\n\nYou communicate with clarity: We move fast with minimal process. You need to articulate what you're building, why it matters, and what you've learned – to engineers, to the CEO, and to customers.\n\nYou're energized by impact: Our customers protect the financial system from criminals. Your experiments will become the tools that make that possible at scale.\n\nAbout the Interview\n\nIntro call\n\nDeep-dive technical interview (no live coding)\n\nFit & motivation\n\nShort paid in-person trial\n\nOffer\n\nCompensation & Benefits\n\nLunch, dinner and snacks at the office\n\nComprehensive healthcare\n\nUnlimited PTO\n\nAnnual offsite (last one in Mexico!)\n\nPaid relocation & one-month temporary housing\n\nLatest tech and as many monitors as you can fit on a desk\n\nCompensation Range: $120K - $220K","company":"Sphinx","rawCompany":"sphinx","city":"Millbrae","state":"CA","isRemote":false,"isActive":false,"createdAt":"2026-04-09T13:28:48.575Z","occupations":[{"code":"15-1252.00","title":"Software Developers","slug":"software-developers"},{"code":"15-1254.00","title":"Web Developers","slug":"web-developers"},{"code":"17-2112.02","title":"Validation Engineers","slug":"validation-engineers"}],"industries":[{"code":"541511","title":"Custom Computer Programming Services","slug":"custom-computer-programming-services"},{"code":"513210","title":"Software Publishers","slug":"software-publishers"},{"code":"541512","title":"Computer Systems Design Services","slug":"computer-systems-design-services"}],"jobPosting":{"@context":"https://schema.org","@type":"JobPosting","title":"Product Engineer","description":"tl;dr: We're automating compliance for banks and fintechs with AI agents that work like human analysts – on a browser.
