United States Remote (Global) Full-time

Datum is hiring a Senior Engineer - Auth

About the Role

Join a team focused on redefining how identity and access are managed in distributed cloud environments. You'll design and operate the foundational authentication and authorization systems that securely connect thousands of cloud instances, enabling seamless interoperability across hybrid and multi-cloud infrastructures.

What You’ll Do

  • Architect and maintain the core identity platform, ensuring secure, scalable access for both human and machine actors
  • Develop customer-facing identity solutions that empower alternative cloud providers to integrate and grow
  • Scale system observability, monitoring, and usage metering across complex, distributed environments
  • Collaborate with technical leadership on strategic initiatives involving key partners, suppliers, and enterprise clients
  • Design distributed systems that support usage patterns ranging from startup deployments to hyperscale operations
  • Implement intelligent routing, load balancing, and failover mechanisms to ensure resilience
  • Build deep observability into networking layers, supporting diagnostics in highly dynamic environments
  • Optimize control plane performance for AI and high-throughput applications in coordination with networking teams
  • Contribute to open-source networking projects and help shape technical direction through community engagement
  • Review and guide contributions from external developers on critical networking components
  • Enforce rigorous standards for code quality, API documentation, and system reliability
  • Represent the organization at technical forums, conferences, and open-source working groups
  • Design Kubernetes-native networking solutions aligned with modern AI deployment patterns
  • Develop security policies and network controls for multi-tenant cloud platforms
  • Integrate service mesh technologies and optimize internal traffic flows
  • Ensure interoperability with major public cloud networking services including AWS, GCP, and Azure

What We’re Looking For

  • Proven experience implementing OAuth in production environments with multiple identity providers, including commercial and social IdPs
  • Deep understanding of authorization models such as ABAC, RBAC, and PBAC, and experience with systems like Zanzibar, SpiceDB, OpenFGA, or Cedar
  • Hands-on work with Workload Identity Federation, SPIFFE, or related identity standards
  • At least five years managing large-scale Kubernetes environments with security as a core design principle
  • Solid background in distributed systems, including consensus, fault tolerance, and asynchronous reconciliation
  • Familiarity with Kubernetes APIs, custom resources, and admission controllers
  • Experience using infrastructure-as-code tools like Flux, Terraform, or Pulumi for provisioning and management

Nice to Have

  • Knowledge of SRv6, edge computing, or modern routing protocols
  • Contributions to open-source networking projects
  • Experience mentoring engineers and guiding technical strategy
  • Understanding of open-source governance and community development practices
  • A passion for building developer-first tools that are intuitive, reliable, and well-documented

Technology Environment

Go, Rust, PostgreSQL, GraphQL, Elasticsearch, Meilisearch, Kubernetes, Flux, Pulumi, Zitadel, Cloudflare, AWS, GCP, Azure, multi-cloud networking, Prometheus, Grafana, OpenTelemetry, network flow analysis, GitHub, CI/CD pipelines, automated testing, and network simulation frameworks.

Why This Work Matters

You’ll play a central role in shaping how trust is established across decentralized systems. Our work emphasizes openness, transparency, and collaboration by default. You’ll contribute directly to public repositories, engage with developers through RFCs and issue discussions, publish technical insights, and help build tools that make secure networking accessible and reliable. We believe secure, operable systems are built through visibility and shared ownership — and your work will directly advance that mission.
