Junior Backend Engineer

About Elbe Systems:

Customers who call us usually reach someone who wrote the code they are asking about. Two developers, a designer and a support lead make up most of the company, so everyone touches the product. We keep recurring meetings to Tuesdays and Thursdays where we can.

• Containerize services with Docker and deploy them to Kubernetes or ECS.
• Tune slow queries, add indexes and read query plans.

• Understanding of concurrency, transactions, idempotency and retries.
• Hands-on experience with AWS, GCP or Azure services.
• Strong SQL and relational data modelling skills.
