• The operational environment must be stable: you will ensure our computing environments are fast and available, in the face of exponential growth and extremely spiky workloads during benefit reload windows. • The software must flow: our pipeline and automated testing give us the confidence to release to production 4x daily, fully automated on a cron during work hours. You will make this process ever faster and smoother. • The software must be secure: you will own the automated security tooling with our dev pipeline and provide visibility to it so that risks can be assessed. • The operational environment must be secure too: here’s where we talk about vulnerability management, network architecture, pen testing, intrusion detection and prevention, lateral movement impediments, application isolation, and so on. You’ll route all the juicy events to our SIEM. • Making this a career highlight for all engineers. Guardrails help you drive fast; no engineer wants to introduce a bug; no one wants to get paged at 3am. You balance kindness and empathy with a burning desire to do things right; you create an environment which is inherently safe and fast, and you give colleagues the ability to thrive within it.
