Job teaser

What you can expect

• Lead a team of engineers designing, developing and operating our employee communication platform (backed by PostgreSQL and RabbitMQ), including specifically our structured, chat-driven workflows.

• At least 70 percent of your time is hands-on engineering work, the remainder is spent on technical leadership tasks.

• Our Flows subsystem is mostly written in Go with some PHP / Symfony, other parts of the system are built on a JVM-based (Kotlin, Micronaut) stack.

• We work remote within international (mostly European), cross-functional agile teams.

• We develop software following modern software engineering practices (API first, code reviews, automated tests, MR environments for exploratory testing before a merge, and some tasteful experimental AI augmentation).

• We deploy (Kubernetes, Helm) and monitor (Grafana, Sentry, Mixpanel) our services within the teams, with the support of a separate team of SREs for on-call duty.

• Join customer calls together with your product manager to understand their specific problems and empower your team to build solutions that cover a majority of customer contexts.

• Take charge on technical topics that are important to you, driving significant decisions, and seeking alignment across teams within our backend guild.
