What are the key skills and qualifications needed to thrive as a union software engineer, and why are they important?

A Union Software Engineer excels with strong programming fundamentals, software development methodologies, and typically holds a degree in computer science or a related field. Familiarity with tools such as Git, continuous integration pipelines, and knowledge of union contracts or labor management software may be required. Outstanding teamwork, effective communication, and adaptability are crucial soft skills for bridging technical and union-specific requirements. These abilities are essential for ensuring software solutions meet organizational standards while supporting fair labor practices and productive collaboration.

How does being a union software engineer differ from a non-union software engineer in terms of work environment and responsibilities?

As a Union Software Engineer, you'll often benefit from defined workplace protections, clearer work hours, and collective bargaining agreements that set standards for pay and benefits. Your responsibilities will still center around software development, but you may also participate in union activities—such as attending meetings, voting on contracts, or collaborating on work-related policies. Daily tasks involve coding, collaborating with cross-functional teams, and ensuring software aligns with both organizational and union requirements. This supportive structure can lead to enhanced job security and a strong sense of community among colleagues.

What is a union software engineer?

A Union Software Engineer is a software developer who is part of a labor union that advocates for fair wages, job security, and better working conditions. They perform the same technical tasks as other software engineers, such as coding, debugging, and system design, but with added protections and benefits negotiated by their union. These unions help ensure transparent employment policies, collective bargaining power, and support for workplace issues. Unionized software engineers may work in various industries, including tech companies, government agencies, and nonprofits.

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.
Role Overview
We're rebuilding interface.ai as an AI-native company - and we want engineers who learn to work this way from day one, not after unlearning somewhere else's habits. As an early-career Software Engineer, you ship production features from your first weeks - real users, real money, real stakes - and take on larger scope as fast as you can carry it.
This is not a rotational program, and you won't be one of a cohort. We hire early-career engineers in ones and twos. Our product and engineering org is deliberately lean relative to the millions of conversations it serves - new engineers get real scope because there's no one else queued up for it. Agents take the routine work; you spend your time on decisions and on 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 - the expected path is owning bounded pieces of the product end-to-end within your first year.
What You'll Own
  • Real features, fast. Production code in your first weeks, shipped to live financial institutions. No sandbox, no staging purgatory.
  • The proof. You own the evals for what you build. In a regulated industry, "it looks right" isn't a standard - evals are how you know what shipped is correct.
  • Your trajectory. Larger scope as fast as you can carry it. Bounded end-to-end ownership within year one is the expected path, not the exception.
  • The AI leverage. Build with LLMs daily - steering agents through the routine work so your time goes where judgment matters.

What We're Looking For
  • You build things nobody asked you to build - a side project with actual users, hackathon wins, merged open-source PRs, or internship work that shipped. Any one of these matters more to us than GPA.
  • You've built with LLMs and you verify their output instead of trusting it. Vibes don't pass review; evals do.
  • A degree in CS or a related field (engineering, math, physics, statistics) - or show us what you've built instead. Self-taught builders are welcome.
  • High agency - you'd rather be handed a problem than a ticket, and you close loops without reminders.
  • Graduating 2024 - December 2026, or up to ~2 years of experience.
  • On-site in downtown San Francisco office 5 days a week - we provide commuter benefits if in the general Bay Area, and relocation support if you're not.

Bonus
  • Competitive programming (Codeforces, ICPC, USACO) - a plus, not a requirement
  • Experience in fintech or banking infrastructure

Benefits
100% paid health, dental & vision care
401(k) & financial wellness perks
Daily meals on us
Commuter benefit
Monthly wellness stipend
Claude Enterprise + frontier AI tools for every employee - build with the best
Brand-new 21st-floor SF office at 44 Montgomery - floor-to-ceiling views, worth showing up to
Discretionary PTO + paid parental leave
Mental health, wellness & family benefits
A mission-driven team shaping the future of banking
Why interface.ai
Series A • $30M raised • Cash-flow positive - we're not burning cash hoping the product works. It works. Customers are live, revenue is real, and the mission is one you can explain to your family without a slide deck.
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.
interface.ai is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees
