Senior Infrastructure Engineer

At Docker, we make app development easier so developers can focus on what matters. Our remote-first team spans the globe, united by a passion for innovation and great developer experiences. With over 20 million monthly users and 20 billion image pulls, Docker is the #1 tool for building, sharing, and running apps—trusted by startups and Fortune 100s alike. We’re growing fast and just getting started. Come join us for a whale of a ride!

Our Infrastructure Engineering team is the backbone of Docker’s cloud-native platform — powering products like Docker Hub, Docker Build Cloud, Docker Scout etc., for millions of developers worldwide. We don’t just keep the lights on — we design, build, and operate the infrastructure services and platforms that make Docker fast, reliable, and secure at global scale.

We own and operate the core building blocks of Docker’s application platform:

• Compute – Multi-tenant EKS clusters, autoscaling, and capacity management.

• Edge & Internal Networking – Ingress, rate limiting, VPN, and secure inter-cluster connectivity.

• Observability – End-to-end metrics, logs, tracing, probes, and alerting.

• Deployment – GitOps workflows powered by Argo CD.

• Security – IAM for services and humans, plus robust secret management.

• Cloud Infra Provisioning & FinOps – Automated cloud resource provisioning and cost transparency.

As a Senior Infrastructure Engineer you will:

• Architect and run globally distributed platform services that hundreds of engineers rely on every day.

• Continuously evolve our compute, edge, observability and deployment layers for maximum resilience, performance, and cost-efficiency at a global scale.

• Lead with automation, Infrastructure as Code, and SLO-driven operations to deliver reliability through software, not toil.

If you thrive on high-impact engineering, love solving complex distributed systems challenges, and want to shape the foundation of one of the most widely used developer platforms on the planet — this is your stage.

This is how we work:

• Code first: we tackle infra problems with software, design docs, and rigorous code review.

• Async & remote‑first: decisions are documented in RFCs; incident reviews are blameless and written.

• Cross‑functional: platform, product, and security engineers collaborate daily to unblock each other.

• Continuous improvement: we ship small, measure impact, and iterate quickly.

• Ship & Operate Cloud Services

  • Design, develop, and ship internal platform services (e.g. provisioning, cost insights, rate‑limiting) in Go or C++.

  • Partner with product and engineering teams to provide paved‑road patterns for deployment, observability, and security.

• Infrastructure as Code & Reliability

  • Codify infrastructure with Terraform and Go; champion GitOps best practices.

  • Define and own SLOs, lead on‑call rotations, conduct blameless post‑mortems, and implement remediations.

  • Advance observability by operating metrics, logs, tracing, probes, and alerting pipelines at cloud scale

• Evolve Compute & Networking foundations

  • Evolve Docker’s ingress stack—Envoy Gateway, ALB/NLB, AWS VPC CNI—to deliver secure, reliable, and cost‑efficient request routing.

  • Operate and scale multi‑tenant EKS clusters; guide the evaluation and adoption of new infrastructure technologies.

• Optimize Cloud Provisioning and Cost

  • Build and operate self-serve cloud resource provisioning platforms at scale.

  • Deliver real-time cost visibility and lead company-wide cost-efficiency initiatives.

• Core Engineering Skills (must‑have)

  • Strong software development skills in Go, C++, Java or similar (design, testing, and code review).

  • Significant experience shipping and operating cloud infrastructure and distributed systems at scale in production (typically 5+ years of relevant work).

  • Solid foundation in Linux, Networking, and Cloud Security.

  • Excellent cross-collaboration, written and verbal communication in a remote environment.

• Depth in one or more of the following (nice‑to‑have)

  • Kubernetes ecosystem and Containerization (EKS, ingress, CNI, service mesh).

  • Observability tooling (OpenTelemetry, Prometheus, Grafana).

  • CI/CD & release automation (GitHub Actions, Argo CD).

  • Cost optimization at scale (FinOps, capacity modelling).

Demonstrated expertise in at least one of these areas is welcome; we don’t expect candidates to be experts in all.

• Complete onboarding and build relationships across Engineering, Security, and Product.

• Ship your first Terraform or internal service change and shadow on-call.

• Gain a deep understanding of our platform architecture, SLOs, and current reliability initiatives.

• Take ownership of a critical service or infrastructure component

• Lead a medium-complexity project from design to production.

• Rotate fully into the on‑call schedule, leading incident response when needed, with confidence.

• Lead a high-impact project from design to production.

• Contribute to refining our platform roadmap and champion initiatives that reduce toil and accelerate delivery.

• Lead the design and launch of a major, company-wide infrastructure initiative.

• Become a recognized subject matter expert in Docker’s cloud infrastructure.

• Mentor newer engineers and influence engineering culture through technical leadership and continuous improvement.
