About the role

Hadrian is seeking a Staff Software Engineer, Identity and Access Management to design and own authentication, authorization, and credential automation across cloud infrastructure, Kubernetes workloads, and factory floor systems as part of the API Platform security foundation.

Responsibilities

  • Design and implement scalable authentication and authorization systems covering both human operators and machine identities across cloud and factory floor environments — serving as the security foundation for the API Platform
  • Own Hadrian's authentication stack: SSO, MFA, OIDC/SAML integrations, and service-to-service auth across AWS, GCP, and future cloud environments
  • Build fine-grained access control systems (RBAC/ABAC/ReBAC) that scale across internal engineering teams, factory systems, and external API partners
  • Develop frameworks, APIs, and CLI tools that automate credential provisioning, rotation, and policy enforcement for both internal teams and external API consumers
  • Build identity and access models for machine-to-machine communication across factory floor systems, Kubernetes workloads, and cloud services
  • Partner with Security to ensure IAM systems meet compliance and audit requirements; troubleshoot complex identity and access issues across distributed systems
  • Work with the API Platform PM to define how IAM capabilities are surfaced as developer-friendly product experiences — for internal engineers and external partners alike
  • Build tooling, SDKs, and documentation that make it easy to integrate with IAM correctly and hard to do so incorrectly
  • Set IAM standards across the engineering org and act as the domain expert on access-sensitive architecture decisions

Qualifications

  • 8–12+ years in software engineering, with 3+ years of focused experience in identity, authentication, or authorization systems at scale
  • Deep, hands-on expertise in modern auth protocols: OAuth 2.0, OpenID Connect (OIDC), SAML, and SCIM
  • Strong understanding of access control models — RBAC, ABAC, and ReBAC — and the ability to make sound architectural tradeoffs between them
  • Experience designing IAM systems across multi-cloud environments (AWS, GCP, Azure)
  • Security-first mindset: threat modeling, risk assessment, and least-privilege principles, and embedding security throughout the SDLC
  • Proficiency in Go, Python, or similar; track record of writing high-quality, maintainable code
  • Ability to set technical direction independently, write clear design docs, and drive alignment across teams
  • Comfort working alongside a PM counterpart — ability to divide technical and product ownership clearly and collaborate effectively
  • Bachelor's degree in Computer Science or related field, or equivalent experience
