Hi there! If you’re seeking a high-impact role within an ambitious and fast-growing software house, you might have just found your perfect match!

Our client is a global leader in Intelligent Observability platforms that unify telemetry data with business outcomes to optimize tech spend and protect revenue in real time.

We are looking for a Senior Backend Engineer to join a high-impact initiative focused on migrating core backend services (Java, Go) from Intel architecture to ARM-based processors (AWS Graviton / Azure Cobalt). Roughly 50–60% of the services are already migrated, and you will own the end-to-end transition and performance optimization of the remaining infrastructure.
