Build like a founder. Ship like Spartan.
Our customers are scaling fast — and so are we. That’s why we’re looking for a Site Reliability Engineer to join our world-class team.
At Spartan, we don’t act like vendors. We embed with startups backed by YC, Pear VC, a16z, Techstars, and more — partnering with founders and engineers from Stanford, MIT, Yale, Google, Amazon, Uber, and beyond. Together, we help launch MVPs in 30 days and scale systems that power millions of users.
This isn’t “just another DevOps role.” It’s a chance to architect Kubernetes infrastructure that’s scalable, secure, and self-healing — ensuring that startups we work with can scale like unicorns from day one.
You’ll also be working at the frontier of AI: 70% of our portfolio today is LLM-powered. Our SREs design the container orchestration, observability, and cost-efficient infra that makes it all possible.
What You’ll Do
- Design and manage multi-cluster, multi-cloud Kubernetes environments (AWS EKS, GCP GKE, Azure AKS, on-prem).
- Build high-availability, disaster-resilient, auto-scalable K8s infrastructure for production workloads.
- Implement GitOps-driven CI/CD pipelines with tools like ArgoCD or FluxCD.
- Lead the deployment, scaling, and lifecycle management of Kubernetes workloads.
- Optimize performance, reliability, and cost efficiency across clusters and regions.
- Secure workloads with RBAC, Network Policies, OPA/Gatekeeper, and vulnerability scanning.
- Collaborate with development teams to containerize and modernize applications.
- Mentor engineers on Kubernetes best practices and SRE workflows.
What We’re Looking For
- Fluent in English — you’ll work directly with US startup founders.
- 3+ years in Kubernetes production environments, 8+ years in DevOps, SRE, or cloud infra roles.
- Proven experience running enterprise-scale clusters in multi-region or hybrid setups.
- Deep knowledge of Docker/OCI runtimes, Linux systems, networking, troubleshooting.
- Strong skills in Infrastructure as Code: Terraform, Helm, Ansible, CloudFormation.
- Proficient with monitoring/observability stacks: DataDog, Prometheus, Grafana, ELK, Jaeger.
- Solid understanding of Kubernetes internals (API server, scheduler, kubelet, controller manager).
Nice-to-Have
- Certifications: CKA, CKAD, CKS.
- Experience with service mesh (Istio, Linkerd, Consul).
- Contributions to open-source K8s or CNCF ecosystem.
- Proficiency in cloud cost optimization for Kubernetes.
- Experience applying SRE best practices and advanced automation tooling.
