• Have excellent written and verbal communication skills

Why you should join Engineering at Euc

• We have a high performance culture
  • We have a high bar for talent, so you’ll get to learn from some of the best engineers in the industry

  • We optimise for velocity and deploy to production hundreds of times a month. Once you merge your code, it’s in prod in minutes
• You’ll get to work with a modern tech stack that we’re always improving. If something isn’t working for us, we’ll iterate until we get it right and everyone on the team is encouraged to help refine it.
  • Frontend: React, React Native + Expo, TypeScript, Apollo, Tailwind
  • Backend: Node (TypeScript) and Go microservices, Federated GraphQL, gRPC, Protobufs, Pub/Sub and Postgres, hosted on GCP Kubernetes Engine (GKE)

  • Euc has a large appetite for product development, so we have a roadmap of innovative, greenfield features to work on

  • We strive for efficiency and invest heavily in internal tooling to improve developer experience
• We’ll invest in your growth, development and career
  • When we introduced Go microservices we invested in upskilling the whole team in a new language
