The Role in a Nutshell

We're looking for a Senior Security Engineer to engineer and secure our multi-cloud environment, the same cloud infrastructure that powers our product. This is a cloud-native, AI-obsessed company, and our cloud is the platform our product runs on. How we design, harden, and evolve it directly shapes what we can build and how fast we can build it safely. As open source software increasingly feeds AI agents as well as human engineers, securing that supply chain end-to-end is core to our mission.

You'll report to the Director of Cyber Resiliency and partner closely with our Developer Platform and IAM teams to make sure every cloud environment we operate is resilient, well-architected, and built to accelerate secure innovation rather than slow it down. We're a late-stage startup, which means priorities, tooling, and scope can shift quickly.

What You'll Do

• Architect and maintain cloud environments built to be secure, resilient, and optimized for performance.
• Partner hands-on with internal engineering teams to embed security into the architecture and tooling developers use every day.
• Work closely with our IAM counterparts to design and enforce identity and access strategies across all cloud environments.
• Harden cloud platforms against emerging threats while keeping them resilient and highly available.
• Bring a DevOps mindset by building automation, pipelines, and guardrails using Terraform/IaC and Kubernetes.
• Help secure the infrastructure behind AI-driven pipelines and agentic workflows as they become a growing consumer of the software supply chain.
• Act as a trusted advisor and collaborator across engineering, translating security requirements into practical, adoptable designs that other teams actually want to use.
• Adapt architecture and priorities as the company scales, reworking plans as needs, tooling, or team structure shift.
• Assist during relevant incident response investigations.

What We're Looking For

• Strong, hands-on GCP administrative experience (AWS and/or Azure experience is a plus).
• Solid DevOps background: comfortable using Terraform/IaC, Kubernetes (GKE), and CI/CD pipelines.
• Familiarity with software supply chain security concepts, particularly SLSA, is a strong plus.
• Experience securing or architecting AI/ML infrastructure or agentic workflows.
• Outstanding interpersonal and communication skills: ability to plan, coordinate, and build consensus across engineering and IAM stakeholders.
• Proven experience architecting and securing complex, multi-cloud environments.
• Comfort with ambiguity and rapid change; prior experience at a fast-moving or late-stage startup is a strong plus.
• A track record of designing systems that are secure, resilient, and built to accelerate engineering velocity.

Salary & Benefits

Base Salary Range: $130,000 — $160,000 USD

• Flexible & Remote-First Culture: Work remotely with team meetup opportunities, bi-annual destination summits, and a monthly stipend for coworking spaces, phone, and internet costs.
• Equity: Stock options upon hire and promotion, secondary offerings participation, and a 10-year exercise window.
• 100% Covered Health Insurance: 100% coverage for health, vision, and dental insurance premiums for you and your dependents.
• Unlimited PTO: Flexible time off to recharge and reset.
• 18 Weeks Paid Parental Leave: 18 weeks for birthing parents and 12 weeks for non-birthing parents.
