We're looking for a hands-on Software Developer who brings a hacker mindset to the table: always probing, questioning, and breaking systems to learn how to build them back stronger. You'll work deeply with Chromium-based browser internals, vanilla JavaScript, , and TypeScript, and you'll own full-lifecycle development in a GCP-powered, containerized environment.

What you'll do:

  • Architect, deploy, and manage infrastructure on GCP using Terraform and Docker.
  • Design and implement CI/CD pipelines that support rapid, reliable releases.
  • Perform code reviews, write automated tests, and champion secure coding practices.
  • Research emerging attack techniques and integrate learnings into product features.

Requirements:

  • 2+ years of professional software development experience working directly with Chromium.
  • Expert-level proficiency in vanilla JavaScript, , and TypeScript.
  • Deep understanding of how web browsers work behind the scenes (rendering engine, DOM, event loop).
  • Strong knowledge of iframes, Web APIs, and client-side interactions.
  • Solid grasp of HTTP(S) fundamentals: request/response lifecycle, methods, headers, and status codes.
  • Demonstrated "hacker mindset": creative problem solving, relentless curiosity, and a proactive approach to uncovering and mitigating weaknesses.
  • Strong communication skills and a collaborative spirit.

Bonus points for:

  • Prior experience in web-app security or browser security.
  • Exposure to CI/CD and DevOps workflows.
  • A portfolio of open-source contributions or personal security research/projects.
  • Deep familiarity with GCP services and best practices.
  • Hands-on experience with Docker for containerization and Terraform for IaC.

What We Offer:

  • The chance to build cutting-edge web-security defenses from the ground up.
  • A tight-knit team culture that values innovation and ownership.
  • Clear career pathways and professional development support.
