Senior Software Engineer

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.

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.

This role is for the engineer who has seen what "going fast" actually costs, knows how to build systems that hold up, and still gets things out the door.

• 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 Type Script and Python; shape frontend experiences in Java Script
• 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

• 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 Type Script 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 —…
