Senior Software Engineer (Golang)

We are expanding our Tech team with a Senior Software Engineer based onsite in our office in Barcelona!

As a Senior Software Engineer, you will design, build, and operate the backend systems that power Fast Track’s platform. Our infrastructure runs on AWS, orchestrated with Kubernetes (EKS) and Docker, and leverages services such as, and Cloudflare for edge delivery and serverless workloads. Data is managed across MySQL, Amazon RDS Aurora, ClickHouse for analytics, and in-memory stores, including Amazon ElastiCache and MemoryDB. Observability is driven by Prometheus and Grafana, with OpenTelemetry being assessed as a future standard.

To be successful in the role, you will need a strong product mindset and enjoy working closely with real customers, and care deeply about building systems that last.
