Why This Role Exists: We build and operate the platform that our engineers and our customers rely on. The platform isn't a product that's ever "finished." It's something we improve continuously. Every deployment, outage, bug, and annoying manual task is an opportunity to make the system better. An L3 Platform Engineer is a fully contributing member of that effort. This isn't a ticket factory. We expect engineers to think critically, collaborate closely, and continuously improve both the platform and the way we build it.

How We Work: Our engineering culture is built on Extreme Programming and Continuous Delivery.

That means:

• Pair programming is our default way of developing software.

• We work in small batches.

• We integrate continuously.

• We automate repetitive work.

• We test first whenever practical.

• We optimize for learning and feedback instead of individual velocity.

• The team owns the outcome.

If you're looking for a role where you're handed tickets, disappear for a week, and come back with a pull request, this isn't it.

What You'll Do: • Build and improve the platform that deploys and operates customer environments.

• Develop infrastructure as code using Ansible, Terraform, Helm, Zarf, Big Bang, Packer, and related tooling.

• Improve Kubernetes platforms and the systems around them.

• Build deployment automation that reduces risk and removes manual work.

• Pair with other engineers to design, implement, and troubleshoot platform capabilities.

• Write automated tests for infrastructure and deployment workflows.

• Improve observability, reliability, security, and recoverability.

• Write documentation that explains why something exists—not just how to type commands.

• Leave every part of the system better than you found it.

What We Expect: You Build for Change

Software is never finished.

Your goal isn't simply to make today's feature work.

Your goal is to leave the code, infrastructure, and deployment process easier to change tomorrow.

You Prefer Automation

If humans perform the same task repeatedly, the system probably needs improvement.

Manual processes are temporary.

Automation is the destination.

You Think in Small Batches

Large changes hide mistakes.

Small changes expose them.

We value engineers who can decompose large problems into safe, incremental improvements.

You Work as Part of the Team

Platform engineering is a collaborative discipline.

You bring potential solutions to the team, clearly explain your reasoning and tradeoffs, and help the team build a shared understanding of the code or design not merely produce it. You are responsible for understanding, validating, and clearly communicating the work you contribute.

You Improve the System

When something goes wrong, we don't stop at fixing it.

We ask:

• Why did this happen?

• Why wasn't it detected sooner?

• How do we make this impossible or at least unlikely next time?

Incidents should improve the platform.

Technical Expectations: You should be comfortable working across most of these areas:

• Kubernetes

• Linux

• Networking fundamentals

• Git and trunk-based development

• GitLab CI

• Infrastructure as Code

• Ansible

• Terraform

• Helm

• Zarf

• Containers

• PKI and certificate management

• Secrets management

• Observability

• Infrastructure testing

• Troubleshooting distributed systems

No one is expected to know everything.

We do expect you to learn quickly and become productive in unfamiliar systems.

How Success Is Measured: Successful L3 engineers consistently help the team:

• Deploy more frequently.

• Deploy more safely.

• Recover from failures faster.

• Remove manual work.

• Reduce operational complexity.

• Improve documentation.

• Increase confidence through testing.

• Deliver changes in small, reversible increments.

• Make the platform easier to operate and easier to evolve.

What We Value: • Simplicity over cleverness.

• Evidence over opinion.

• Learning over ego.

• Automation over repetition.

• Continuous improvement over perfection.

• Team outcomes over individual heroics.

What Doesn't Fit Here: • Building knowledge silos.

• Defending "the way we've always done it."

• Optimizing for personal productivity instead of team throughput.

• Big-bang rewrites when incremental change will work.

• Manual work that should be automated.

• Complexity without a clear operational benefit.
