Security Engineer

At Scale, our Security Architecture team builds the foundations that allow engineers to ship fast without compromising security. From securing modern Type Script services and cloud infrastructure to enabling safe adoption of AI-driven systems, our work shapes how products are designed, deployed, and operated across the company.

• Design and build secure application and infrastructure foundations that engineering teams use by default.
• Partner with product and engineering teams across the full SDLC, from RFC and architecture reviews through implementation, launch, and long-term maintenance.
• Conduct deep architecture, design, and code reviews, identifying systemic risks beyond individual vulnerabilities.
• Build and maintain secure cloud and CI/CD foundations using Infrastructure as Code.
• Act as a technical advisor to engineering teams, helping them ship secure, maintainable, production-grade systems.
• Serve as a technical point of contact during high-impact security events, contributing engineering and operational leadership.
• Influence security strategy and technical direction through tooling, standards, and clear technical guidance.
• Mentor engineers and help raise the overall security and engineering maturity of the organization.

• Staff-level experience in 3+ of the areas below (Senior at a minimum):
• Deep, production-level expertise in Type Script and the Node.js ecosystem, including frameworks such as Next.js and modern tooling.
• A strong track record of shipping and owning production software, including experience with testing, deployment, and on-call operations.
• Experience conducting security, architecture, and design reviews, not just code-level audits.
• Deep familiarity with AWS cloud primitives, including IAM, and experience designing systems for multiple environments.
• Hands‑on experience with Infrastructure as Code (Terraform, CDK, or similar), treating infrastructure as software.
• Strong ability to structure ambiguous problems, diagnose root causes independently, and propose pragmatic solutions.
• Excellent communication skills, with the ability to explain complex security and architectural tradeoffs to technical and non‑technical stakeholders.
• A proven ability to influence cross‑functional teams and drive adoption of secure patterns without blocking velocity.

• Experience with Kubernetes and container security, including network policies and workload isolation.
• Background in Platform Engineering or Developer Productivity, such as building shared tooling, CLIs, frameworks, or base images.
• Proficiency in Python, particularly in environments supporting AI/ML workloads.
• Familiarity with AI / LLM systems, agentic workflows, and emerging AI security concerns.
• Experience working in large‑scale monorepos or with modern build systems (e.g., Bazel).
• Exposure to data security, data pipelines, or compliance‑driven systems (e.g., GDPR).
• Willingness to learn and build automation around compliance environments (e.g., FedRAMP, Gov Cloud).
• Interest in emerging infrastructure challenges such as GPU or HPC cluster security.

Base salary range: $264,000 – $330,000 USD (San Francisco, New York, Seattle). The position also includes equity, comprehensive health, dental, and vision coverage, retirement benefits, a learning and development stipend, generous PTO, and may be eligible for additional benefits such as a commuter stipend.

At Scale, our mission is to develop reliable AI systems for the world’s most important decisions.
