OnHires

Senior Full-Stack Engineer

OnHires Brussels

Stellenbeschreibung:

Remote | Globally Distributed Team

Data Platform / DevTools Product

Full-time | Long-term | Stock Options Included

Why This Role Stands Out

Join a product-driven startup backed by the investors in Zoom, LinkedIn, 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 mission-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

You’ll join the Applications team to build features end-to-end — from data processing and APIs to frontend components like browser extensions and IDE plugins.

The focus is backend-heavy, but solid frontend skills are required for delivering user-facing developer tools.

  • Build and own features across backend, APIs, and frontend
  • Develop internal and public APIs
  • Integrate with the company’s data platform
  • Contribute to browser/IDE plugins and dev-facing tools
  • Support CI/CD pipelines and cloud-based delivery
  • Collaborate with the infrastructure team (Kubernetes, GCP)
  • Write well-tested, maintainable code
  • Participate in code reviews and mentor other engineers

Tech Stack

Primary Backend: Go, Kotlin, Java, or Scala — language flexibility is welcome; JVM experience is especially valued
Frontend: TypeScript + any modern JS framework (React, Vue, Angular, Svelte — all accepted)
Infrastructure: Kubernetes, Terraform, Docker, GCP
Data Layer: PostgreSQL
DevOps: CI/CD pipelines, GitHub Actions, CircleCI

You Might Be a Great Fit If You Have

8+ years of experience in software engineering
Strong backend expertise (Go, Kotlin, Java, or Scala)
Hands-on experience with RESTful APIs and data-heavy applications
Familiarity with cloud infrastructure and Kubernetes
Solid frontend skills (TypeScript, integration-level — no need for deep UI work)
Ability to deliver production-ready features end-to-end
Comfortable working across the stack and switching layers as needed
Experience with developer tools or data platforms is a plus
English: Upper-Intermediate or higher

What’s In It for You

Stock options in a fast-growing, VC-backed startup
100% remote team with async-friendly culture
Collaborate with world-class engineers from NASA, Meta, MIT, AWS
Work on a high-impact devtools product used by engineering and security teams
Unlimited PTO and flexible hours
High ownership, zero micromanagement, no legacy
