Software Engineer, Security Platform

Quick Facts

• Role: Software Engineer, Security Platform
• Focus: Identity, credentials, and audit capabilities for securing Spacetime across connected and disconnected environments

Description

You will build authentication and authorization capabilities, PKI components, workload identity, and supporting SDKs for a security platform used in commercial cloud, government cloud, and classified or disconnected settings. The platform must make trust decisions verifiably offline where upstream services are unavailable. You will implement reconstructable audit and structured logging, contribute to threat models and mitigations, and run the services you build in production.

Responsibilities

• Build authentication and authorization: token validation, trust anchors, and permission model operators configure
• Implement authorization for delegation, multi-tenancy, and machine-to-machine access
• Build and maintain PKI: certificate issuance, rotation, and revocation
• Build workload identity and libraries that present it
• Build and maintain auth SDKs used to access Spacetime APIs
• Implement access controls for secrets and keys and client libraries for access
• Implement audit and structured logging to make authorization decisions reconstructable offline in regulated/classified/disconnected environments
• Contribute to threat models and build root-cause mitigations
• Operate services: availability, upgrades, security maintenance, on-call, and incident response
• Work with product and infrastructure teams to translate requirements into platform capabilities

Requirements

• 5+ years of backend software engineering on production services
• Go experience (or readiness to work in Go daily)
• Hands-on experience with authentication/authorization, identity provider integration, certificate authority, or secrets/key management
• Understanding of token-based authentication failure modes and prevention
• Working knowledge of Kubernetes and cloud infrastructure
• Comfort owning production components including on-call and incident response
• Clear written and verbal communication
• Eligibility for ITAR/EAR requirements to access export-controlled information

Benefits

• Innovative environment working on aerospace communications
• Direct impact on critical national security programs
• Growth opportunities for professional development
• Inclusive culture
• Flexible hybrid remote/in-office work
• Competitive salary (USD 155,000–175,000) plus comprehensive benefits, paid time off, and equity options
