Job description

About the team + role

We are building an elite team, applying frontier technologies to the world's biggest financial problems. We're looking for bold builders and sharp problem-solvers who are wired to deliver great outcomes. Robinhood isn't a place for complacency, it's where ambitious people do the best work of their careers. The DevX team's mission is to build and operate the core developer infrastructure at Robinhood. Our team owns and scales the systems that thousands of engineers rely on daily, partnering with software developers across the company to make development fast, reliable, and cost-efficient!

As a Senior Software Developer, you will focus on building and scaling our developer infrastructure. You will manage and optimize monorepo builds with Bazel and own the remote build execution cluster that powers them, and you will scale CI pipelines to be fast, safe, and reliable across thousands of daily builds. You will also improve the developer onboarding experience and provide remote development environments to accelerate development  workflows. In this role, you will ensure developers can code, test, and deploy with minimal friction. This is an incredible opportunity to make a massive difference for the entire engineering organization!

This role is based in our Toronto, ON office, with in-person attendance expected at least 3 days per week.     

At Robinhood, we believe in the power of in-person work to accelerate progress, spark innovation, and strengthen community. Our office experience is intentional, energizing, and designed to fully support high-performing teams.

What you'll do
  • Manage and optimize monorepo builds using Bazel and own the remote build execution cluster, ensuring fast, stable builds and short feedback loops for our engineering teams.
  • Scale CI pipelines to support thousands of daily builds, focusing on speed, safety, and reliability, while managing GitHub repository configurations, pre-merge checks, and test executions.
  • Improve the developer onboarding experience, reducing time-to-first-commit and making it easy for new engineers to get productive.
  • Provide and maintain remote development environments to accelerate local workflows and ensure developers can code, test, and deploy with minimal friction.
What you bring
  • Experience building and maintaining developer infrastructure, CI/CD pipelines, or large-scale build systems (such as Bazel).
  • Proficiency in writing clean, maintainable code in Go or Python.
  • Experience with distributed or remote build execution systems, and a solid understanding of containerization and orchestration using Kubernetes.
  • Strong problem-solving skills and a focus on improving developer productivity, onboarding, and engineering workflows.
What we offer
  • Challenging, high-impact work to grow your career
  • Performance driven compensation with multipliers for outsized impact, bonus programs, and equity ownership
  • Top tier benefits to fuel your work, including supplemental health insurance, ancillary insurance, and mental health support programs
  • Lifestyle wallet - a highly flexible employer-paid benefits spending account expenses beyond traditional benefits such as wellness, childcare, learning, and more.
  • Time off to recharge including company holidays, paid time off, sick time, paid volunteer time off, parental leave, and more!
  • Exceptional office experience with catered meals, events, and comfortable workspaces. 
  • Monthly commuter stipend to help offset in-office commuting costs
