What The Giger Team Does

The Giger team builds and maintains one of Deel’s most powerful internal platforms: a sandbox system that enables engineers to develop, test, and deploy faster than ever. Giger allows product teams to spin up fully functional, production-like environments in minutes, complete with real databases, services, queues, and storage. Each sandbox is completely isolated, empowering teams to experiment freely, test infrastructure changes, and validate code safely at scale.

What You’ll Do

• Design, build, and maintain the control plane that powers hundreds of dynamic developer sandboxes.
• Develop backend tooling and services that automate sandbox creation, orchestration, and lifecycle management.
• Productize and provide infra as a platform including DBs, caches, object storage and queueing systems.
• Scale & tune the cluster to provide capacity for volatile workloads. You’ll become hands on with Karpenter/VPA/KEDA policies, right-sizing, pod density, bin-packing, and scheduling strategies for diverse, bursty workloads.
• Constantly track and optimize costs to be efficient. At our k8s scale all tiny decisions matter, from compute to storage and data transfer.
• Own the networking setup to mimic what we have in Production but pair it with greater DevEx at scale of hundreds of sandboxes - traffic routing and interception, ingress tuning, serving assets.
• Implement and evolve observability within sandboxes.
• Partner with Sandboxes SRE team to ensure uptime and reliability of hundreds of sandboxes daily.
• Work with Deel engineering to improve their DevEx and productize day to day needs into self-service platform.
