Release Engineer

Release Engineer

EngFlow does more than make builds faster. It improves the operating performance of the whole engineering organization.

The best teams can assemble powerful build and test infrastructure; the hard part is operating it reliably, with visibility and cost control, as demand grows. That is Build Management at AI Scale: operating build and test as production infrastructure, including execution, observability, reliability, and cost control, so teams can build, test, diagnose, and release even as they write code at AI speed. Engineering organizations, including BMW, Databricks, Snap, Canva, Lyft, and Asana, run on EngFlow. The result is high performance at scale. EngFlow was founded by the engineers who created and maintain Bazel, and is backed by Andreessen Horowitz and Tiger Global.

Companies like Canva, Databricks, and MongoDB rely on EngFlow to keep their builds fast and their engineers unblocked. As a Release Engineer, you're the person who makes sure our platform gets to them — reliably, on cadence, every week.

You'll own the full release lifecycle for EngFlow's remote execution platform: from cutting the release and managing phased rollouts across dozens of production clusters worldwide, to triaging regressions, keeping CI green, and driving the operational discipline that lets the rest of the engineering team move fast. You'll work directly with a wide range of engineers, including EngFlow product engineers and Bazel contributors.

If you're interested in high-ownership work, care deeply about reliability, and want to understand a complex distributed system end-to-end, this is a role where you'll matter from day one.

Key Responsibilities

• Own the release cycle: Drive the weekly releases from branch cut to full production rollout. Manage phased deployment across rc, preview, general, and cautious tracks using Terraform and internal tooling — balancing speed with the stability our customers depend on.
• Keep production healthy: Deploy configuration changes to a global fleet of clusters, resolve Terraform drift, and ensure every cluster stays within its maintenance and certificate windows.
• Run the rotation: Each week one engineer shields the team from operational noise — that's you, on rotation. Triage the Linear queue daily, route issues to the right team, investigate customer-reported cluster problems, and facilitate the weekly Production Ops meeting.
• Own CI health: Keep the master branch green across all EngFlow-managed repositories. Hunt down flaky tests, fix what you can, and leave good context for what you can't.
• Be the connective tissue during incidents: Coordinate between engineers when production issues escalate. Deploy hotfixes and configuration changes within agreed maintenance windows, without dropping the ball on the rest of the week.
• Make the next release easier than the last: Improve runbooks, sharpen the handover process, and reduce toil — not just for yourself, but for every engineer who comes after you on rotation.

Requirements

• Release & deployment experience: You've owned production deployments for a distributed or cloud-hosted service — you know what a bad rollout looks like and how to catch it early.
• Infrastructure as code: Hands-on Terraform experience in AWS, GCP, and other cloud providers. You're comfortable reading a plan, spotting drift, and making a call on whether to apply or revert.
• Build system familiarity: You can read a Bazel, Gradle, Maven, or CMake build and understand what's happening. You don't need to be a compiler engineer, but build failures shouldn't be a black box.
• CI/CD operations: Experience keeping a CI system healthy — investigating failures, managing flaky tests, and understanding the difference between a systemic problem and a one-off.
• Linux & shell: The shell is your natural habitat for log analysis, scripting, and debugging production issues.
• Async communication: Strong written English — you write clear updates, handover summaries, and runbooks that people actually read.
• Ownership of outcomes: Comfortable being the person the team leans on for a week at a time, and escalating when you need help.

Nice to have

• Direct experience with Bazel or the Remote Execution API (REAPI)
• Programming proficiency in Java, Go, Python, or TypeScript for automation and internal tooling
• Experience with PagerDuty and Linear (or equivalent incident and issue-tracking workflows)
• Background in platform or DevOps engineering at a product-led company
• Familiarity with Kubernetes or container orchestration in production
