Join an early-stage startup.
Accelerate economic opportunity.

Join us as a Backend Engineer to build and scale the infrastructure that powers financial access for millions of underserved Americans. This role is for you if you want to own critical systems end-to-end and care deeply about performance, reliability, and scalability. You'll be expected to aggressively leverage AI-assisted development tools to dramatically accelerate your output and maximize impact, all while maintaining strong code quality and system reliability.

• Kovo is expanding access to financial tools for people historically excluded from the traditional credit system. We believe everyone deserves the opportunity for economic independence, and we’re building products that help people establish financial identity and unlock opportunity.

• Over the past three years, Kovo has grown revenue 20x while maintaining exceptional capital efficiency. We rank above the 99th percentile in revenue-per-employee benchmarks, reflecting the leverage of a small, high-performing team.
