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.
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.
When something goes wrong, we don’t stop at fixing it.
•
Why wasn’t it detected sooner?
•
How do we make this impossible or at least unlikely next time?
Incidents should improve the platform.
You should be comfortable working across most of these areas:
•
Git and trunk-based development
•
PKI and certificate management
•
Troubleshooting distributed systems
No one is expected to know everything.
We do expect you to learn quickly and become productive in unfamiliar systems.
Successful L3 engineers consistently help the team:
•
Recover from failures faster.
•
Reduce operational complexity.
•
Increase confidence through testing.
•
Deliver changes in small, reversible increments.
•
Make the platform easier to operate and easier to evolve.
