Software Engineer, Security Infrastructure

At SIFT, we’re redefining how modern machines are built, tested, and operated. Our platform provides engineers with real-time observability over high-frequency telemetry, eliminating bottlenecks and enabling faster, more reliable development.

SIFT was born from our work at SpaceX on Dragon, Falcon, Starlink, and Starship—where scaling telemetry, debugging flight systems, and ensuring mission reliability demanded new infrastructure. Founded by a team from SpaceX, Google, and Palantir, Sift is built for mission-critical systems where precision and scalability are non-negotiable.

About the Role

As a Software Engineer, Security Infrastructure, you will not just maintain a security checklist; you will define the posture, architecture, and practices that keep our products and infrastructure secure in the most demanding environments.

You will be both hands-on and strategic, building controls, automating compliance, and owning SIFT’s security posture end-to-end, with technical security engineering as the primary focus. You will set the standard for how we protect our systems and data, ensuring resilience against modern threats while partnering with external compliance specialists to meet the requirements of aerospace, defense, and enterprise sectors.

In This Role, You’ll:

- Build and maintain tooling, scripts, services, and automation that assess, enforce, and monitor security and compliance controls across our AWS cloud environments, Kubernetes clusters, and CI/CD pipelines.

- Develop lightweight internal solutions (e.g., policy-as-code, custom scanners, CI/CD integrations) that make security and compliance automatic, auditable, and invisible to the rest of engineering.

- Embed security guardrails directly into infrastructure-as-code (Terraform), container orchestration, and deployment workflows so that secure-by-default becomes the path of least resistance.

- Partner closely with the infrastructure and platform engineering teams to harden cloud-native sys...
