Our values are reflected in our product and in our team. Department Platform Engineering Who You Are You are a tooling‑focused engineer who obsesses over developer productivity. You’ve built and maintained CI/CD pipelines, developer tooling, and automation that makes engineering teams faster. You understand that the best developer tools disappear into the background – they just work. You’re equally comfortable debugging a flaky GitHub Actions workflow and designing a new internal CLI. You care deeply about reducing friction and cognitive load for your fellow engineers. This is a foundational role. You’ll be one of the first dedicated engineers on a platform organization supporting 300+ engineers. You’ll shape not just the technical foundations but the culture and practices of the team.

In this role, your foundational knowledge, skills, abilities, and personal attributes are anchored in the following: Good judgment – the exercise of critical thinking, analyzing and assessing problems and implications, identifying patterns, making connections of underlying issues, understanding risks and developing mitigation strategies, and taking ownership of the outcome. Resourcefulness – a can‑do approach, even in the face of obstacles and constraints by assessing what’s in front of you and effectively and efficiently optimizing what you have, whether it’s working on something new or thinking about how to do something better. Teamwork and communication – putting our collective best together through documentation, collaboration, relationship‑building, listening, empathy, recruiting, and evangelism. Influence and leadership – fostering a community of knowledge‑sharing, collaboration, mentorship, and forward‑thinking. Skills and knowledge – the capacity to actively learn and apply specific domain knowledge, know‑how, and best practices to continually enhance and improve.
