• Set technical standards for code quality, design systems, testing, and developer workflows

Why This Matters:

The software you build will be used by professionals managing critical, safety-sensitive infrastructure. Your work directly impacts efficiency, reliability, and safety, helping them execute workflows faster, with confidence, and at scale.

This is a high-impact, ownership-first role at a startup where your decisions shape both the product and the engineering culture.
