DevOps/Platform Engineer

Overview:

• Build and run a reliable platform for services and data workflows across Kubernetes and Prefect.
• Own CI/CD, observability, security, and developer experience for Python/Go/Rust services.

Responsibilities:

• Design, provision, and operate Kubernetes workloads (deployments, networking, autoscaling, storage).
• Build and maintain GitLab CI/CD pipelines for Python, Go, and Rust services (build, test, scan, release).
• Operate Prefect (agents, work queues, deployments, concurrency limits, task execution environments).
• Implement environment strategy and promotion flow (dev/staging/prod) with clear release gates.
• Create golden paths and templates for FastAPI microservices and Prefect flows.
• Manage secrets, configuration, and access (e.g., GitLab variables, K8s secrets).
• Establish observability: logging, metrics, traces, alerting, runbooks, and SLOs.
• Operate data stores (MySQL, PostgreSQL, Redis): provisioning, backups, migration execution, monitoring, and capacity planning.
• Optimise build and runtime costs (container images, caching, autoscaling, resource requests/limits).
• Lead incident response, postmortems, and reliability improvements.

You have:

• 4+ years in DevOps/SRE/Platform roles with production Kubernetes.
• Strong GitLab CI/CD experience (pipelines, runners, caching, artifact management).
• Proficiency with containers and image optimization; comfortable with Linux internals and networking.
• Hands-on with Prefect in production (deployments, flow orchestration, storage, results).
• Familiar with operating MySQL/PostgreSQL/Redis in production (availability, performance, backups).
• Scripting/automation with Python or Go; ability to read Rust build pipelines.
• Solid understanding of security fundamentals (least privilege, image scanning, SBOM, secret hygiene).
• Experience instrumenting systems and creating actionable alerts.

Nice to have:

• Helm/Kustomize, policy-as-code (OPA), and basic gRPC.
• Performance tuning for high‑throughput data or API services.
• Experience in multi‑tenant or multi‑cluster environments.
