Offer description

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.

• 5+ years of hands-on experience building scalable services in Java and/or Go.
• Practical experience with AWS (EKS, EC2) and Kubernetes.
• Good understanding of CPU architectures (x86 vs. ARM) and performance tuning for cloud-native applications.
• Working knowledge of Terraform, Docker, and CI/CD automation.
• Openness to occasional pre-scheduled evening calls (between 17:00–21:00 CET) to sync with US-based stakeholders.
• Refactor, optimize, and migrate core Java and Go services to run efficiently on ARM CPU architectures (AWS Graviton / Azure Cobalt).
• Analyze performance bottlenecks and hardware-level instruction behavior during x86 to ARM migration.
• Work with Kubernetes (EKS) to deploy, monitor, and scale migrated workloads in enterprise environments.
• Ensure seamless CI/CD delivery pipelines and infrastructure automation using Terraform and AWS services.
• Collaborate closely with cloud architecture and platform security teams across global time zones.
