Platform Engineer
Builds the internal platform (tooling, environments, golden paths) that lets product teams ship fast and well, autonomously.
Why this hire matters.
Past 20-30 engineers, each person's productivity depends less on their talent than on the quality of the platform they work on. The Platform Engineer treats developers as customers: providing golden paths to create a service, deploy and monitor — without tickets or waiting. The stakes are mathematical: removing 10% friction across 40 engineers equals 4 hires saved. Without a platform, every team reinvents its infrastructure, standards diverge and onboarding drags on. The opposite risk exists too: a platform built without listening to its users becomes a constraint teams route around. Hire for product sense as much as technical depth.
Key missions.
- Design the internal developer platform (IDP) and its golden paths
