About the company

Our client is a fast-growing fintech company.

The role

Raydar is recruiting for this role on behalf of our client. Build and own features across the full stack, from interface to services to deployment, on new products in a small, early engineering group. The work leans toward backend systems that handle heavy transaction traffic, and the role carries wide influence over architecture and engineering practice.

What you'll do

- Deliver complete features across the user interface, server logic and deployment.

- Design and scale backend services for lending, payments, payouts and ledger workloads that must handle very high volume.

- Build workflow tools for small businesses covering payroll, point of sale and inventory tracking, connected to a regulated banking partner.

- Adopt AI-assisted development practices and help shape how the team builds software.

- Work closely with product, design and engineering colleagues to ship quickly in a greenfield setting.


Requirements

What we're looking for

- Stronger on server-side work than interface work, with experience across the whole stack.

- Experience owning a production system at large scale, with an example of a difficult technical problem solved there.

- Comfort in fast-paced, young companies that are scaling quickly.

- Experience building both front-end and back-end systems.

- Four to eight or more years of software engineering experience.

Bonus points

- Background working with databases and message queuing systems.

- Experience in payments engineering, such as payouts, ledgers or cross-border transactions.

- Experience at a large technology company followed by a move to a startup, or on a high-performing large-company team.

- A computer science degree from a top-ranked U.S. university.
