Lead Backend Engineer (Flow) (m/f/d)

Empowering every employee.

Our mission is to be the world's most used AI employee experience platform by changing the way frontline employees work.

At Flip, we have a clear goal: to revolutionize the world for frontline workers and give them a voice. Become a Flip Game Changer and work with an unbeatable team to ensure that all employees, no matter where they work, have access to their company's internal information. If you’re ready to make an impact and shape the work lives of millions of people, then you’ve come to the right place!

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.

What you bring to the table

We’re seeking a skilled, experienced engineer ready to step up and own complex challenges.

What we offer you

The exact balance will be discussed during your interview.
