Job summary

You’ll define the security function from the ground up, partner with Platform and product teams, and scale the team as we grow. This role blends hands-on technical ownership with architectural leadership in a fast-paced startup environment.

Qualifications

• 8+ years across infrastructure engineering, platform engineering, SRE, DevOps, cloud security, or security engineering.
• 4+ years with meaningful ownership of security architecture or security programs for a production SaaS platform.
• Deep hands-on experience with AWS, Kubernetes/EKS, Terraform or equivalent infrastructure as code, CI/CD, observability, and production incident response.

• Demonstrated ownership of SOC 2 or a comparable compliance program in a fast-moving environment.
• Proficiency in a programming or automation language such as Python, Go, or TypeScript, plus experience in an early-stage or high-growth company where systems had to be built, not inherited.

Responsibilities

• Own production cloud foundation across AWS, Kubernetes/EKS, networking, compute, storage, data services, environment isolation, and production access.
• Build reusable Terraform modules, CI/CD pipelines, deployment automation, configuration standards, and self-service paths that make environments repeatable and safe.
• Improve reliability and operability through observability, alerting, SLOs, capacity and cost management, backup and recovery, disaster recovery, and production-readiness standards.
• Participate in the engineering on-call model, lead infrastructure incidents when needed, and convert incidents and operational toil into durable platform improvements.
• Partner with Platform and product engineering teams on architecture and rollout patterns, reducing manual work and broad privileges through automation and secure defaults.
• Lead threat modeling and secure design reviews, build a secure SDLC, and own identity, secrets, key management, encryption, and data isolation controls.
