Role Overview:
As a Software Engineer on the Security Platform team, you’ll build the identity, credentials, and audit capabilities that secure Spacetime. The team owns security for Aalyria products, and we build each capability once so it works the same in every environment Spacetime ships into. A system built this way produces its own compliance evidence. You’ll work with senior engineers on the team and with product engineers across Aalyria.
Spacetime runs in commercial cloud, government cloud, and classified or disconnected environments, and that last category shapes the work. Trust decisions must be verifiable offline, at sites we cannot reach, with no upstream to call. Most identity platforms assume a connected world. Ours cannot. Our security platform is evolving, with capabilities that grew up alongside Spacetime being consolidated into one coherent layer with identity at its center, and the engineers we hire now will help build it. The people who thrive here are curious about how security systems fail, care about getting the details right, and take ownership of what they ship.
Key Responsibilities:
•
Build authentication and authorization capabilities for Spacetime, including token validation, trust anchors, and the permission model operators configure
•
Implement authorization that holds up under delegation, multi tenancy, and machine to machine access
•
Build and maintain PKI components: certificate issuance, rotation, and revocation
•
Build workload identity and the libraries services use to present it
•
Build and maintain the auth SDKs that Aalyria engineering teams and customers use to reach Spacetime APIs
•
Build the access controls for secrets and keys, and the client libraries teams use to reach them
•
Implement audit and structured logging that makes authorization decisions reconstructable after the fact, including in regulated, classified, and disconnected environments
•
Contribute to threat models and build mitigations that fix root causes rather than single findings
•
Run what you build in production: availability, upgrades, security maintenance, on call, and incident response
•
Work with product, infrastructure, and developer platform engineers to turn their requirements into capabilities they adopt on their own, and apply the platform’s security standards for hardened images, supply chain, and pipeline gates
