Principal Software Engineer (Safeguards)

Were an early-stage company building innovative software solutions with a commitment to shipping rock-solid, reliable, safe software. We’re searching for someone who loves to ensure that software does exactly what it’s supposed to do every time – and when it doesn’t, we know immediately.
You love ensuring properties of distributed systems are satisfied in simple ways that enable developers to ship relentlessly with high confidence that code will not impact customers in unexpected ways. Fundamentally, safeguards dont just protect - they empower speed by creating confidence to move faster.
Responsibilities

Build systems that enable graduated availability of new code and content - build dev, test, pre‑prod, and prod systems that gradually make new code or content available to wider sets of environments to increase safety, decrease risk, and increase predictability
Build systems that enable reproducibility of outcomes - examples of this include automated methods to learn when operating system vendors or cloud service providers change - potentially impacting the runtime activity we observe
Build simple, easy to use frameworks that enable developers to quickly write new unit and integration tests for new capabilities that enable the graduated availability system and reproducibility system
Build systems that enable content developers to quickly write and deploy content using the graduated availability system and reproducibility system
Top candidates for this role will have:

Experience designing and shipping commercially available software products at scale that customers love

At least 12 years of experience
Ability to thrive in a fully remote organization
