As an Intermediate Backend Engineer on our Verify:
Runner Core group within the Verify:
Runner organization, you’ll help build and evolve Git Lab Runner, the interface between Git Lab and our customers’ CI infrastructure. Whether jobs run on Kubernetes clusters, cloud VMs, or on‑premises hardware, Git Lab Runner makes it happen. Each week, Runners process millions of jobs for , and our container images are downloaded hundreds of millions of times.

You’ll collaborate on technical initiatives and contribute to design and implementation, taking on work that matches your experience while growing your impact over time. You’ll learn from how customers use our CI/CD capabilities and use that insight to help the team solve real‑world scaling and reliability challenges. This input can come from bug reports, customer escalations, or feedback on executor behavior and performance.

Git Lab Runner users often have demanding CI/CD requirements, and many rely on the infrastructure you help build as a mission‑critical part of their software delivery workflows.

Here’s a glimpse of some of the things we’re working on and where we’re headed:

• Job Routing :
  Transforming Git Lab Runner’s job scheduling from HTTP polling to intelligent, server‑mediated routing that enables runner prioritization, admission control, and distributed autoscaling coordination.
• We’ve already kicked this off with Admission Control, and you could contribute to its iteration.
• Externalizing CI :
  Transforming Git Lab CI from static YAML configuration to dynamic, programmable pipelines where jobs can create other jobs at runtime.
• Job Volume Mounts :
  Enabling CI jobs to mount Git Lab repositories and artifacts as file system volumes, providing instant, lightweight access to multi‑repository content without full git clones.

• Design and develop features and improvements for Git Lab Runner that are secure, well‑tested, and high‑performance, with a focus on strong architecture in Go services, appropriate for an intermediate‑level engineer.
• Partner with the Product Manager and other Senior Engineers to assess the technical feasibility and scope of Runner‑related feature requests, contributing your perspective and asking clarifying questions.
• Contribute to architectural decisions that modernize Runner’s technology stack, favoring solutions that address root causes over fixes that treat symptoms.
• Take end‑to‑end ownership of your features from design through implementation, code review, deployment, monitoring, and iterative refinement.
• Collaborate closely with other engineers on the team and within the Runner Organization through code reviews, pairing, and knowledge sharing, both learning from others and helping raise the overall technical bar.
• Work with cross‑functional partners, including Support and Product, to help diagnose, troubleshoot, and resolve customer issues related to Git Lab Runner and CI Functions, and feed those learnings back into the product.
