**Description & Requirements**
Our team builds the platform that Bloomberg engineering teams use to deploy and run production services. BPaaS (Bloomberg Platform as a Service) is a multi-tenant system built on Kubernetes. We extend K8s with custom controllers and operators that manage the full lifecycle of workloads across Bloomberg’s infrastructure. Today that spans a large fleet of clusters, thousands of nodes, tens of thousands of deployments, and more than a hundred thousand pods, scale where your controllers’ correctness and efficiency genuinely matter.
You’ll be joining BPaaS Scalability, the team focused on automating fleet-wide operations across nearly a hundred clusters. Managing that many clusters by hand doesn’t work. The solution isn’t scripts and runbooks, it’s software that handles it reliably. You’ll design Custom Resource Definitions, implement controllers that reconcile desired state across the fleet, and write the Go and Python that makes it work. This is a software engineering role, not a DevOps role.
We’re a small, collaborative team where everyone has input on technical direction. The problems we’re solving don’t have obvious answers, so we figure them out together. We embrace open source first and contribute back where we can.
**We’ll trust you to:**
– Design and implement Kubernetes operators and custom controllers that manage workloads across a large multi-tenant platform
– Write production code (Go, Python) that interacts with the Kubernetes API (client-go, controller-runtime)
– Own features end-to-end, from CRD design through implementation to rollout
– Reason about distributed systems concerns: consistency, failure modes, leader election, and graceful degradation
– Collaborate with other platform and infrastructure teams to integrate with Bloomberg-wide systems
– Improve the reliability and operability of the platform through better abstractions
– Bring ideas and challenge existing approaches. We’d rather hear a better way than defend the current one
**You’ll need to have:**
– Strong programming ability in Go and/or Python
– Experience with Kubernetes internals, not just deploying to K8s, but extending it (e.g. operators, controllers, CRDs, admission webhooks)
– Understanding of distributed systems fundamentals (consistency, reconciliation, failure handling)
– Curiosity about how things work under the hood and willingness to dig into unfamiliar systems
– A degree in Computer Science, Engineering, or equivalent experience
**We’d love to see:**
– Contributions to open-source Kubernetes ecosystem projects (controller-runtime, kubebuilder, operator-sdk, etc.)
– Experience building multi-tenant platforms or control planes
– Familiarity with TypeScript/JavaScript for CLI or UI tooling
– Experience designing APIs (REST or gRPC) for developer-facing platforms
**If this sounds like you:**
