Hadrian Automation • Los Angeles, CA

1d

About The Position

Hadrian is building autonomous factories to help aerospace and defense companies manufacture rockets, satellites, jets, and ships up to 10x faster and up to 2x cheaper by combining advanced software, robotics, and full-stack manufacturing. They are expanding rapidly with a new 290,000-square-foot facility in Mesa, Arizona, creating 350 new jobs, launching Hadrian Maritime, and introducing a Factory-as-a-Service model. The company is backed by leading investors and aims to reindustrialize American manufacturing. The Staff Software Engineer, Identity and Access Management, will be responsible for building the security foundation for Hadrian's API Platform, which connects external partners, internal services, and factory floor systems. This role involves owning authentication, authorization, and credential management across complex multi-cloud and physically distributed environments, working closely with the API Platform PM to ensure IAM capabilities are integrated as first-class developer experiences. This is a product pillar role, requiring ownership of the technical layer end-to-end, setting scaling direction, and defining secure-by-default practices across Hadrian's builds.

Requirements

• 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: you understand threat modeling, risk assessment, and least-privilege principles, and you embed 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 — you can divide technical and product ownership clearly and collaborate effectively
• Bachelor's degree in Computer Science or related field, or equivalent experience

Nice To Haves

• Experience building IAM systems that serve external developer ecosystems — not just internal users
• Experience building identity systems for non-human entities: service accounts, workload identity, machine certificates, Kubernetes service accounts
• Familiarity with policy-as-code frameworks (OPA, Casbin, or similar)
• Experience with zero-trust network architecture
• Hands-on experience with secrets management platforms (Vault or equivalent) at scale
• Prior experience in aerospace, defense, or manufacturing environments with ITAR or export control considerations
• Experience working alongside a PM on a developer-facing platform product

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

Benefits

• Medical, dental, vision, and life insurance plans for employees
• 401k
• Relocation support may be provided for certain situations, based on business need.
• Flexible vacation policy
