About The Position

Due to increased demand, we’re looking to hire a Cloud Infrastructure / Platform Engineer to join our team supporting our internal developer platform built on AWS. This is a hands-on role for someone with a few years of relevant experience who wants to grow in platform engineering, cloud operations, observability, and developer experience. This role is a good fit for someone who wants to grow beyond day-to-day platform support and into a broader platform engineering career. You’ll have exposure to both infrastructure and developer workflows, with a chance to make a real impact on cloud cost, platform reliability, and developer productivity. You’ll partner closely with Infrastructure, Security, IT, and Spire’s software development teams to improve how our platform runs, how our developers ship software, and how efficiently we spend it on AWS.
