Job Description:

Remote | Globally Distributed Team
Data Platform / Dev
Tools Product

Why This Role Stands Out

Join a product-driven startup backed by the investors in Zoom, Linked
In, Uber, and Twitter — a rare opportunity to shape a technically ambitious platform from the ground up.
You’ll work alongside engineers from NASA, AWS, Meta, MIT, and Stanford on a
- critical devtools product used by engineering and security teams to optimize how software is built and delivered.

As an early team member, you’ll receive a significant equity stake - not just symbolic stock options, but real ownership in a company solving deep technical challenges. It’s a chance to build something meaningful and benefit directly from its success.

What You’ll Work On

Build and own features across backend, APIs, and frontend

Develop internal and public APIs

Integrate with the company’s data platform

Support CI/CD pipelines and
- based delivery

Collaborate with the infrastructure team (Kubernetes, GCP)

Write
- tested, maintainable code

Participate in code reviews and mentor other engineers

Primary Backend: Go, Kotlin, Java, or Scala — language flexibility is welcome; JVM experience is especially valued

Frontend: Type
Script + any modern JS framework (React, Vue, Angular, Svelte — all accepted)

Dev
Ops: CI/CD pipelines, Git
Hub Actions, Circle
CI

8+ years of experience in software engineering

Strong backend expertise (Go, Kotlin, Java, or Scala)

Hands-on experience with RESTful APIs and
