As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack - from electrons to tokens - to power the world's most ambitious AI workloads. When you join Crusoe, you join a team that is building the future, faster.\nWe're in the midst of the greatest industrial revolution of our time. The demand for AI compute is boundless, and power is a bottleneck. We're solving that - with an energy-first approach that makes AI infrastructure better for the world and faster for the people innovating with AI.\nWe're looking for problem-solving, opportunity-finding teammates with a sense of urgency, who believe in the scale of our ambition and thrive on a path not fully paved - people who want to grow their careers alongside a team of experts across energy, manufacturing, data center construction, and cloud services.\nIf you want to do the most meaningful work of your career, help our customers and partners advance their AI strategies, and be part of a high-performing team that believes in each other, come build with us at Crusoe.\nAbout the Role:\nCrusoe is building the world's favorite AI-first cloud, and the Identity & Access Management (IAM) team is the security bedrock our customers trust to run their most demanding AI and GPU workloads. IAM sits on the hot path for every request in the cloud, authorizing millions of requests at single-digit-millisecond latency, so reliability and performance are non-negotiable. We are seeking seasoned Senior Software Engineers to design, build, and scale this platform: the fine-grained authorization model for Crusoe Cloud resources, enterprise SSO and identity federation, multi-tenant organization hierarchies, identity for the agentic-AI era, and credential and secrets management. As a Senior Engineer, you'll own the design and delivery of significant IAM services end-to-end, partner across teams, and help raise the technical bar through mentorship and code review.\nWhat You'll Be Working On:\nDesign and Deliver IAM Services - Own the end-to-end design, development, and operation of core IAM services - fine-grained authorization, authentication, identity federation, and identity lifecycle - that secure every request in Crusoe's AI cloud.\n\nSolve Complex AuthN/AuthZ Problems - Design and build solutions to complex authentication and authorization scenarios at the platform level, including the fine-grained authorization model for accessing Crusoe Cloud resources.\n\nEngineer for the Hot Path - Deliver low-latency, fault-tolerant services that remain highly available under load, since IAM is on the critical path for every API call.\n\nHarden Security Posture - Apply security best practices such as OAuth2/OIDC, RBAC/ABAC, and session and credential management across the services you own.\n\nContribute to Architecture - Contribute to architectural decisions that support security, reliability, and maintainability across the company.\n\nCollaborate Across Teams - Work with product, design, security, and SRE to evaluate tools, frameworks, and customer needs, aligning priorities to ship customer-first solutions.\n\nMentor and Elevate - Mentor engineers, enhance hiring and onboarding practices, perform code reviews, and contribute to a strong, inclusive engineering culture.\n\nWhat You'll Bring to the Team:\nEducation & Experience - Bachelor's degree in Computer Science or a related field (or equivalent practical experience) and 5+ years of software development experience, primarily in Go and gRPC (or an equivalent compiled language).\n\nDistributed Systems Expertise - Proven ability to design and scale fault-tolerant distributed systems and develop managed cloud services.\n\nSecurity & Identity Expertise - Hands-on experience building authentication and authorization into production services - OAuth2/OIDC, RBAC/ABAC, and session, credential, and secrets management - along with strong security fundamentals such as encryption and TLS.\n\nProduction Ownership - Experience operating the services you build: on-call, observability (metrics, logging, and alerting), and keeping latency-sensitive systems reliable.\n\nAPI & Data Modeling - Strong API design (gRPC and REST) and experience modeling multi-tenant identity hierarchies - users, organizations, projects, and resource boundaries.\n\nCollaboration Skills - Ability to work with cross-functional teams to align priorities and deliver customer-first solutions.\n\nMentorship Abilities - Experience mentoring engineers and giving thoughtful, constructive code reviews.\n\nCommunication Skills - Exceptional ability to articulate complex ideas and align technical solutions with customer and business needs.\n\nBonus Points\nHands-on experience with IAM / authorization frameworks such as Ory, SpiceDB, or OpenFGA.\n\nFamiliarity with additional identity standards and protocols: SAML, JWT, identity federation, SCIM, and WebAuthn.\n\nExperience with cloud-native tooling such as Kubernetes, Docker, Terraform, and CI/CD systems.\n\nExperience with multi-tenant isolation, audit, or compliance (e.g., SOC 2) for security-critical platforms.\n\nExperience with identity for AI agents and agentic workloads, or with GPU / AI cloud infrastructure.\n\nContributions to open-source security, identity, or distributed-systems projects.\n\nYou don't need to check every box. If you bring strong fundamentals and are excited about this work, we encourage you to apply, even if you aren't a 100% skill or experience match.\nBenefits:\nCompetitive compensation and equity packages\n\nRestricted Stock Units\n\nPaid time off, paid holidays & leave of absence programs\n\nComprehensive health, dental & vision insurance\n\nEmployer contributions to HSA account\n\nPaid parental leave\n\nPaid life insurance, short-term and long-term disability\n\nProfessional development & tuition reimbursement\n\nMental health & wellness support\n\nCommuter benefits (parking & transit)\n\nCell phone stipend\n\n401(k) Retirement plan with company match up to 4% of salary\n\nVolunteer time off\n\nGlobal travel insurance & emergency assistance\n\nDaily meals allowance\n\nAdditional perks & programs specific to location\n\nCompensation Range\nCompensation will be paid in the range of up to $170,000 -$205,000 + Bonus.
