Project

Build migration & Open Source Transition

Project Scope

We are managing a large-scale CI/CD infrastructure for a project that is currently transitioning its build system to an Open Source model. The existing environment is hosted on Azure and utilizes CircleCI. Our goal is to migrate this entire ecosystem to GitHub Actions, merging private repositories into public ones to foster community collaboration.

This is a high-stakes environment supporting over 40 developers where “every minute counts.” The CI pipeline is big – a single test run can utilize up to 30 machines – meaning performance and reliability are important.

Challenges

• Strategic Migration: You will be responsible for architecting and executing the move from CircleCI to GitHub Actions 

• Scalability at Scale: Managing a complex CI that handles 30-machine parallel test runs and optimizing it for speed.

• Repository Consolidation: Merging codebases into public Open Source repositories.

• Ownership: You won’t just be executing tasks; you will be coming up with the plan, testing it, and adjusting the strategy to ensure the final success of the migration.

Tech stack

CircleCI, GitHub Actions, Bash, Scala, sbt, Azure

What we expect in general:

• Autonomy: A self-starter mindset with the ability to take full ownership of the migration strategy from planning to execution.

• Communication: Strong ability to collaborate with developers and stakeholders to ensure the build system meets the needs of the 40+ person engineering team.

• Scripting Proficiency: Advanced skills in Bash and/or Scala for automation and tooling.

• Tooling Knowledge: Experience with CircleCI or GitHub Actions. Familiarity with sbt is a significant plus.

• Pragmatic Problem Solving: The ability to adjust plans on the fly based on trial and error to achieve the final result.
