Full Job Description

Flex is building the AI-native private bank for business owners.

We’re re-architecting the entire financial system for entrepreneurs—from the first dollar a business earns to how that value compounds, moves, and is ultimately spent in real life. Banking, credit, payments, personal finance, and financial operations—rebuilt from the ground up as a single, intelligent system. Flex is the full financial home for ambitious owners.

Since launching publicly in September 2023, Flex has scaled from zero to nine-figure annualized revenue, with a clear path to profitability by late 2026. We move fast, ship relentlessly, and operate with extreme ownership.

Our customers are affluent business owners ($3–$200M in revenue)—the backbone of the economy and one of the most underserved segments in finance. They’re stuck with outdated banks and fragmented tools. We’re replacing all of it. The opportunity is massive: a ~$1T+ revenue market hiding in plain sight. Our ambition is to build a $100B+ company by delivering a product that is fundamentally better—not incrementally improved.

Flex has raised $100M+ in equity and $300M+ in debt.

Mission-critical problems: We build software that directly controls how money moves at scale.
High bar, low ego: Small teams, exceptional people, real ownership.
Speed over comfort: We prioritize execution, quality, clarity, and results.
Enduring impact: What we’re building will define how a generation of owners runs their businesses.

Team & Locations

We hire exceptional people who want to build hard things and see their work matter immediately. Roles are available in: San Francisco, Miami, New York, and fully remote.

Flex Fuels Ambition.

About the Role

We're looking for a Software Engineer II to help build product features that power financial services. You'll work on systems that handle payments, credit, and other core products that our customers rely on daily to drive business operations.

✅ What You’ll Do

Own the full lifecycle of medium-sized features and tasks across our product stack
Build user-facing features, internal tools, APIs, and backend services
Write clear, maintainable, and tested code that you'll be responsible for long-term
Participate in code reviews and provide timely feedback to teammates
Build features with the end product and user in mind, not just the code
Reason carefully about how your work extends in service of larger product needs
Build upon systems and features that others depend on
Balance speed with reliability and compliance in a regulated environment
Collaborate with other engineers and product team members to deliver high-impact work
️What Makes You a Great Fit

Have strong fundamentals in software development and ability to work effectively within established systems
Product sense—you think about the user impact and business value of your work
Ability to take responsibility for the maintenance and quality of what you build
Experience with financial services, regulated industries, or handling sensitive data is a plus but not required
Ability to research and proactively solve problems, bring solutions to the table
English proficiency
A strong work ethic

Technical environment: We primarily use Typescript, PostgreSQL, and GCP. We are building in a monorepo with a lean towards rapid value creation through trunk based development. Deploying to production 3-5 times a week is the average velocity of a team member.

What matters to us: We value ownership, product sense, and clear communication. You should be someone who thinks beyond just shipping code to understanding the impact on users and the business. We're a small team, so everyone wears multiple hats and jumps in where needed.

Why Join Us

Build something generational — Capture the full lifecycle of money for ambitious business owners.

Work on real money, real risk — Payments, credit, and banking at serious scale.

Solve hard problems — AI, underwriting, compliance, and global finance from first principles.

True ownership — Small teams, high trust, real accountability.

Founder-level exposure — Direct access to leadership, customers, and investors.

High bar, high taste — Move fast without cutting corners.

Elite peers — People here are builders, not tourists.

Real upside — Meaningful equity if you help build something big.
