Responsibilities

  • Design, build, and evolve the citizen-developer platform and tools for creating and operating automations and applications.
  • Establish secure software development lifecycle guardrails so compliance and security are built into citizen-developer applications by default.
  • Build self-serve development and operations tooling that reduces dependence on central platform engineers.
  • Design, build, and maintain Temporal-based workflow infrastructure supporting multi-tenancy, high availability, and cost effectiveness.
  • Contribute to the Kubernetes and GitOps foundation using ArgoCD, Helm, and Terraform.
  • Participate in code reviews and technical design discussions.
  • Join the on-call rotation for workflow-related services, lead incident response, and drive long-term fixes.
  • Document standards, best practices, and reference architectures for teams building on the platform.

Requirements

  • 6+ years of experience in software or platform engineering, building and operating backend or platform services in production.
  • Hands-on experience with at least one strongly typed backend language such as Golang or Java, plus familiarity with Python or Bash for tooling and automation.
  • Experience designing and building internal platforms or developer tooling used by multiple teams, with a strong focus on developer experience.
  • Experience with Kubernetes and GitOps tooling, ideally ArgoCD and Terraform.
  • Experience supporting non-product engineering users or low-code, no-code, or citizen-developer environments is a strong plus.
  • Experience with Temporal or similar workflow and orchestration systems such as Cadence, Step Functions, or Airflow is a huge plus.
  • Experience with large-scale stateful workloads such as Redis clusters, Cassandra, or HBase is a huge plus.
  • Ability to work collaboratively across teams and translate platform constraints into clear APIs, contracts, and paved paths.
  • Proactive problem-solving skills and the ability to navigate ambiguity and drive complex technical problems to completion.

Benefits

  • The position includes an on-call rotation for workflow-related services.
