Software Engineer II

About interface.ai http://interface.ai interface.ai http://interface.ai is the agentic AI platform for financial services — bringing conversational and agentic AI to the credit unions and community banks that serve everyday Americans. We're not a lab, we're not a demo company, and we're not burning runway on hypotheticals. We are in production, generating real revenue, and on a mission that matters: making intelligent financial services available to the millions of people who've never had a private banker. More than 100 banks and credit unions run on interface.ai http://interface.ai, reaching over 10 million people. Many products are live today; the biggest bets — an AI-first contact center and an AI-native consumer banking experience — are what comes next. Backed by $30M in Series A funding and already cash-flow positive, we're at the inflection point: a proven product, paying customers, and a profitable business rebuilding itself as an AI-native company to lead a world where agents, not software, do the work.   Role Overview We're rebuilding interface.ai http://interface.ai as an AI-native company — and the engineering that powers millions of live banking conversations has to be built by people who own what they ship. As a Software Engineer II, you own modules end-to-end: the design, the build, the evals, and the quality in production. This is not a maintain-someone-else's-code job. The product works, more than 100 financial institutions run on it, and the business is cash-flow positive. The job is to carry real scope inside a deliberately lean engineering org — one that serves millions of conversations precisely because every engineer on it ships like it's theirs. Agents take the routine work; you spend your time on the design decisions and the evaluation harnesses that prove what shipped is correct. We build in person, from San Francisco. At our stage speed is the whole game, and the fastest path between a problem and a decision is two engineers at the same desk. Scope, title, and pay track what you've put into production — tenure doesn't enter the math.   What You'll Own - Your modules. End-to-end ownership — design, build, eval, ship, iterate. You make the design calls within your module and answer for its quality in production. - The ship cadence. Weekly releases to live financial institutions — real customers, real money, real consequences. No demos, no staging purgatory. - The AI leverage. Build with LLMs daily. Steer agents through the routine work so your time goes to the decisions that matter. - The proof. The evaluation harnesses that verify model output. In a regulated industry, "it looks right" isn't a standard — evals are how you know what shipped is correct.   What We're Looking For - You've designed, built, and shipped production software end-to-end — and owned its quality after launch, not just at launch. - You've built real product with LLMs, and you're rigorous about verifying model output.
