Who are we looking for?

Pinwheel is looking for a combination Backend / Platform Engineer who thrives at the intersection of backend engineering, infrastructure, and developer enablement. This role owns the systems our engineering team depends on to build, deploy, and scale products; everything from Kubernetes and CI/CD pipelines to observability and infrastructure-as-code (IaC).

You’ll work closely with product and engineering teams to enable fast, reliable delivery while designing systems that are secure, scalable, and built for the future.

• Provision, monitor, and optimize cloud infrastructure for reliability, scalability, and performance
• Support new product initiatives by deploying and managing microservices in Kubernetes environments
• Design and manage infrastructure-as-code and deployment workflows using Terraform, Helm, and GitOps tools (e.g., Flux, ArgoCD)
• Improve CI/CD pipelines and developer workflows using tools like CircleCI and GitHub Actions
• Implement observability solutions (metrics, logging, alerting) to improve system visibility and operational response
• Architect secure, cloud-native solutions across AWS, Azure, and/or GCP
• Partner with engineering teams to deliver production-ready, compliant platform capabilities

What qualifications are necessary?

• 3–5+ years of backend software engineering experience
• 2+ years of platform, infrastructure, or DevOps experience
• Strong experience with Python and/or Go
• Hands‑on experience with cloud infrastructure and cloud‑native architectures
• Experience running containerized workloads, especially in Kubernetes
• Familiarity with infrastructure‑as‑code tools like Terraform and Helm
• Experience with CI/CD systems and modern delivery practices (GitOps, CircleCI, GitHub Actions)
• Experience with observability tools such as Datadog, Prometheus, or Grafana
• Strong understanding of building reliable, scalable, high‑performance systems
• Ability to quickly learn new technologies and work independently in unfamiliar systems
• A curious, self‑directed mindset with strong problem‑solving skills

Nice to Have

• Experience with PKI, encryption, mTLS, or security‑focused infrastructure
• Familiarity with GitOps tools like Flux or ArgoCD
• Experience integrating AI tooling (e.g., MCP servers) into production environments
• Exposure to compliance‑focused systems (PCI, SOC 2, ISO, etc.)
