Principal Platform Engineer (Architecture & Enablement)

What You Will Do Daily :

• Build the "Glue" : You won't just design on whiteboards; you will write the high-leverage code—whether it’s a custom Backstage plugin, a specific GitHub Action, or a CLI in Go / Python—that bridges the gap between our raw infrastructure and the developer experience.
• Experiment & Prototype : You will create "Tracer Bullet" implementations for new architectural standards, proving they work in code before advocating for their adoption across the fleet.
• Engage as an Embedded Expert : You will partner directly with Product Squads, not as an auditor, but as a co-pilot—helping them adopt the Golden Paths and gathering direct feedback to iterate on the platform product.
• Mentorship & Technical Leadership : You will elevate the technical bar of the Platform Engineering division, mentoring other engineers on modern software design, automation strategies, and "Platform as a Product" thinking.
