Job description

About interface.ai

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, 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.

The Role

As a Senior Software Engineer, you’re not just writing code you’re setting the technical direction for the systems you own. You’ll work directly with our VP of Engineering, CTO and Co-Founder Bruce Kim, and CEO Srinivas Njay in a collaborative, in-person environment where the best ideas win and shipping is the scoreboard.

Areas You Could Work On

• Lead the design and implementation of platform services scalable, observable, and maintainable systems that power our AI products
• Own technical decisions end-to-end: architecture, APIs, data models, performance, and security
• Build and extend backend systems in TypeScript and Python; shape frontend experiences in JavaScript
• Drive the integration of LLM-based and agentic AI capabilities into production systems this is applied AI engineering, not research
• Define and enforce engineering standards: code review, testing strategies, deployment practices, and incident response
• Embed AI-native tooling (Claude Code, Cursor) into your daily workflow and help the team get better at it
• Work side-by-side with product, design, and data in the office, in real time, every day

What We’re Looking For

• 5+ years of software engineering experience with a track record of shipping impactful, production-grade systems
• A portfolio of work you led, not just contributed to you can walk through design decisions, trade-offs, and outcomes
• Deep proficiency in TypeScript and/or Python; solid JavaScript for frontend contributions
• Strong platform engineering instincts: distributed systems, API design, cloud architecture (AWS/GCP), observability
• Fluent in AI/ML engineering: you’ve built on top of LLMs, understand prompt engineering, and know where AI adds value and where it doesn’t
• Experience designing systems under real constraints latency, reliability, cost, and scale
• BS/BA in Computer Science; graduate degree a plus (we take fundamentals seriously)
• Self-directed and decisive: you identify problems before they’re assigned, propose solutions before they’re requested, and close loops without reminders
• In SF, committed to 5 days/week the collaboration is real and intentional

Bonus Points

• Production experience with conversational AI, dialogue systems, NLP pipelines, or agentic architectures
• Background in fintech, banking infrastructure, or regulated financial environments
• Experience being an early engineer at a startup that shipped successfully

Benefits

• 100% paid health, dental & vision care
• 401(k) & financial wellness perks
• Discretionary PTO + paid parental leave
• Mental health, wellness & family benefits
• A mission-driven team shaping the future of banking

You’ll work directly with Bruce Kim (CTO / Co-Founder), who sets the technical bar and goes deep on the hardest problems, and Srinivas Njay (CEO), who is hands-on daily across product and engineering. Founding-team-tier equity, top-of-market base, comprehensive benefits, and a modern San Francisco office worth showing up to. The team is small enough that your judgment shapes everything, and the market is large enough that what you build will matter for a long time.
