  • Automate provisioning, configuration, deployment, upgrades, rollback, backup, recovery, and operational workflows through version-controlled repeatable pipelines.
  • Operate Kubernetes-based containerized application services and own platform capabilities in production.
  • Create documented self-service identity and authorization workflows that reduce manual intervention for product engineering teams.
  • Implement and support permission models, tenant isolation, authentication flows, token lifecycle management, federation, SSO, and external identity-provider integrations.
  • Diagnose production failures and improve reliability through observability, performance testing, safe rollouts, and automation.
  • Provide technical leadership through architecture and design decisions, code reviews, engineering standards, and support for other engineers.

Requirements

  • Substantial hands-on experience building and operating platforms or shared infrastructure for software engineering teams.
  • Strong coding and scripting skills applied to infrastructure, automation, deployment tooling, or integrations, with experience maintaining code, reviewing changes, and using automated tests.

  • Practical experience with a major public cloud platform, Infrastructure as Code, CI/CD, and GitOps.
  • Experience building reusable platform capabilities or self-service workflows that reduce manual engineering work.
  • Sound understanding of APIs, networking, data stores, and distributed-system behavior, with the ability to troubleshoot production issues.
  • Practical experience implementing authentication and access control in software applications, APIs, or shared platform services.
  • Working knowledge of OAuth 2.0, OpenID Connect, token-based authentication, secure validation, permission models, least privilege, and tenant isolation.
  • Ability to translate security requirements into working software, automated tests, and maintainable platform capabilities.
  • Evidence of technical leadership through design decisions, code reviews, engineering standards, and support for other engineers.
  • Experience with Curity, Keycloak, SpiceDB or comparable authorization engines, enterprise federation, SAML, policy-as-code, Go, PostgreSQL, Kafka, or RedPanda is preferred but not required.
  • Candidates should have demonstrable hands-on experience designing, building, and shipping production AI applications; experience limited to AI-assisted development tools is insufficient.

Benefits

  • Flexible hybrid work opportunities and flexibility to support diverse needs and lifestyles.
  • Inclusive workplace experiences and opportunities to collaborate with colleagues in a global environment.
