Essential Job Duties Our ideal Staff Software Engineer, Permissions will be the technical authority for BambooHR's next-generation permission service — designing and building the system that securely controls what every user, token, and agent can do across our platform. You'll own the architecture of a greenfield permissions service from the ground up, define AuthN/AuthZ patterns for 180+ product domains, and be the connective tissue between the Token Titans team and the engineering organization that depends on the work you ship. If you get energy from solving hard identity and access problems at scale— and doing it in a way that other engineers actually want to build on — this role is for you. You will: Drive the delivery of the architecture and delivery of a new permission service — from first design doc to production, including data model, policy evaluation engine, enforcement APIs, and token contract Refine and Define BambooHR's AuthN/AuthZ standards — the patterns for authentication flows, token issuance, scoped authorization, and role/attribute-based access control that product teams rely on Design the API contract for the permission service: how callers request access decisions, how policies are defined, and how enforcement is decoupled from individual product domains Drive token strategy — JWT issuance, rotation, scoping, revocation, and the relationship between tokens and permissions across both human and machine (API/agent) callers Partner with product and platform teams to translate domain-specific access control requirements into reusable permission primitives that scale across the organization Lead architectural reviews for features with AuthN/AuthZ implications; catch design debt before it ships Collaborate with Security and Compliance to ensure the permission service meets audit, least-privilege, and zero-trust requirements Set the technical bar for the Token Titans team: mentor engineers, lead RFCs, and ensure implementation quality matches architectural intent What You Need to Get the Job Done 10+ years of software engineering experience, with at least 3 years operating at Staff or Principal level Deep expertise in identity and access management — authentication protocols (OAuth 2.0, OIDC, SAML), authorization models (RBAC, ABAC, ReBAC), and token lifecycle management (JWTs, opaque tokens, refresh/rotation strategies) Demonstrated experience designing and building AuthN/AuthZ systems at scale — not just integrating with them, but owning the architecture that others build on Strong instincts for policy-as-code, permission modeling, and how to express complex access rules as a clean, evolvable data model Experience designing or reviewing OpenAPI specifications, event-driven architectures, and cross-service communication patterns in a service-oriented or microservice environment Strong backend engineering fundamentals; comfort working in a PHP monolith with modern architectural patterns Proven ability to drive org-wide architectural decisions — writing RFCs, leading reviews, building consensus across teams with competing priorities Excellent communication skills: precise written specs, verbal presentations to engineering leadership, and the ability to explain tradeoffs in identity and security without losing the room What Will Make Us REALLY Love You Hands‑on experience building a permission service or authorization framework from scratch (e.g., Zanzibar-style, OPA-based, or custom policy engine) Familiarity with Okta, Auth0, or similar identity platforms — and a clear sense of what to build vs. what to buy Experience with fine‑grained authorization patterns (relationship‑based access control, contextual policies, delegated permissions) Background in multi‑tenant SaaS — understanding how permission models must account for org hierarchy, role inheritance, and tenant isolation Prior work on API token systems — scoped tokens, machine-to-machine auth, token introspection, or access token exchange (OAuth token exchange RFC 8693) Experience with secrets management, certificate rotation, or secure credential storage in production environments Familiarity with zero‑trust architecture principles and how they apply to internal service-to-service authorization What You'll Love About Us Great Company Culture that has been recognized by multiple organizations like Inc, and Salt Lake Tribune Comprehensive health, life, and disability insurance Generous leave policies that include 4 weeks of vacation, 12 company holidays, parental leave, and volunteer time off so you can enjoy quality of life 401k plans with up to 6% company match $2000 Paid Vacation bonus EAP through Headspace Check out all our benefits that benefit you About Us At BambooHR, we're building something different: we're building a people intelligence platform that transforms HR and sets people free to do great work!
