Lemongrass is a SAP focused consultancy support customers as they look to keep up with SAP's "migration to the cloud".
We not so infrequently run into Frankenstein solutions built by our customers that need to be understood, cleaned up, and then potentially right sized or retired. If you enjoy and/or have experience rolling up your sleeves, diving into a poorly documented Kafka deployments, and coming out the other side the hero with crisp documentation in hand and a plan for longer term re-architecture activity, I've got the role for you.

Tired of trying to beat kube into shape? Does writing YAML to ship code fill you with utter dread? Dream of a future where deploying software is simple, and you don't need an army of infrastructure engineers to build that perfect janky bash script™ to make life easy?
We're Railway, and we think infrastructure can be better. So far we've built out a platform loved by hundreds of thousands of users who simply tell us "Give me Postgres", "Deploy this repo", and we make it happen
Fair warning! The problems are complex: home-rolled hypervisors, cut-above container orchestration, over/under/whateverlay networks, virtio device drivers, edge proxies, IAM that doesn't suck, kitchen sinks - we need to build it and we're looking for likeminded individuals who think this stuff is fun.
Three open roles (apply below!):
