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 They're stuck with outdated banks and fragmented tools.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.

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.

  • Lead by example and mentor engineers in all aspects of planning, development and testing.
  • Be a catalyst for driving best-in-class technology frameworks and tooling while staying engaged with the latest technology trends.
  • Be on call, with the expectation to ability to solve problems and find solutions for the servicing team

What You Need
  • Proficiency in NodeJS+Typescript and server design principles.
  • An understanding and interest in architectural patterns for highly available, scalable, low-latency, asynchronous systems
  • Ability to hold yourself and the team to high standards.
  • Strong communication (written and verbal) and interpersonal skills.
  • Ability to provide in-depth evaluation of multiple technical directions and determine tradeoffs of each.
  • Strong propensity to make data-driven decisions on technical architecture and project prioritization.
  • Exposure to modular monoliths and micro-services along with the benefits and challenges they bring.
  • Experience with any cloud based provider like Google Cloud, AWS, or Azure.
  • Four or more years of relevant industry experience with a track record of shipping high-quality products and features at scale.
  • A strong work ethic and are ready to grind
  • Have built and shipped a working project or product, ideally something complex
