Responsibilities
- Design, build, and operate production Kubernetes clusters with networking, workload isolation, resource management, scheduling, and multi-region topologies.
- Build and extend Crossplane infrastructure orchestration using Kubernetes custom resources, controllers, operators, compositions, providers, managed resources, and reconciliation patterns.
- Develop reusable self-service platform capabilities, services, middleware, and infrastructure abstractions consumed by multiple engineering teams.
- Write and maintain production services, Kubernetes controllers, operators, and platform tooling in Go, Python, or Java, with Go preferred.
- Build HTTP, REST, and gRPC interfaces and maintain meaningful unit and integration tests.
- Implement service mesh capabilities including mTLS, workload identity, authentication, authorization, and traffic management.
- Design and maintain reusable Terraform modules and Crossplane provisioning workflows, including GitOps and CI/CD delivery workflows.
- Lead incident response, investigate root causes, troubleshoot Kubernetes and distributed systems, and implement durable reliability fixes.
- Define SLOs and build metrics, dashboards, alerting policies, distributed tracing, and diagnostic instrumentation.
- Optimize containerized workloads for performance, cost, resource efficiency, and blast-radius reduction.
- Support cloud migration initiatives across providers or environments while maintaining reliability and minimizing downtime.
- Partner with data engineering, product, security, and infrastructure teams; contribute to architecture direction, design reviews, mentoring, and technical decisions.
Requirements
- At least 7 years of professional experience in software, platform, infrastructure, or site reliability engineering, including significant production distributed-systems experience.
- Degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
- Demonstrated experience building and operating production Kubernetes platforms rather than only deploying applications to them.
- Production software development experience in Go, Python, or Java, with strong preference for Go.
- Experience building infrastructure or internal developer platforms used by multiple engineering teams.
- Experience designing and maintaining reusable Terraform modules or equivalent infrastructure abstractions.
- Strong knowledge of Kubernetes internals, networking, CNI, NetworkPolicy, resource management, scheduling, cluster lifecycle, and behavior under load.
- Hands-on experience with Kubernetes APIs, custom resources, controllers, operators, and reconciliation patterns.
- Experience with Crossplane or declarative infrastructure orchestration and provisioning; Crossplane expertise is highly preferred.
- Strong GitOps knowledge, preferably with Argo CD, and experience with service meshes such as Istio, Envoy, or Linkerd, including mTLS and workload identity.
- Solid Linux fundamentals, including cgroups, networking, and resource management.
- Production experience with GCP, AWS, or Azure; multi-cloud experience is preferred.
- Experience with Prometheus, Grafana, OpenTelemetry, and query languages such as PromQL.
- Production experience with relational databases, including PostgreSQL or managed Postgres-compatible services, replication, and failover.
- Experience with Docker and container tooling, debugging, performance profiling, resilient distributed systems, high availability, and disaster recovery.
- Preferred experience includes CNCF or Kubernetes ecosystem contributions; Crossplane, KEDA, Argo CD, Strimzi, or Envoy; large-scale data platforms using Apache Kafka, Apache Flink, or Apache Spark; Alibaba Cloud; Ginkgo and Gomega; identity and access management; Bazel; compliance frameworks; and Kubernetes certifications such as CKA, CKAD, or KCNA.
- Ability to read Java, work in a monorepo, communicate technical trade-offs clearly, and independently drive complex infrastructure initiatives from design through production.
Benefits
- Remote role based in Brazil with coverage during Pacific Hours, 8:00 AM–5:00 PM PST.
