materialsecurity - Senior Software Engineer, Cloud Office Security

• Strong Backend & Systems Skills: Strong software engineering fundamentals and the ability to ship high-quality backend code. You're comfortable designing and operating systems that integrate with third-party APIs at scale — rate limits, retries, idempotency, and messy data are familiar territory. • Full-Stack Comfort: You can work across the stack and are comfortable contributing to the frontend (TypeScript/React) when features require it. Deep frontend specialization isn't required, but you should be effective shipping end-to-end. • Product Sense: You care about the user experience and can make reasonable UX trade-offs with design partners. • Curiosity About Agentic Systems: Experience or strong interest in building LLM-powered agents in production, including prompt design, tool use, and evaluation. • Technical Maturity & Ownership: You write high-quality code without much oversight, understand which risks to take and which to avoid, and stay engaged through production rollout and beyond. • Attitude & Ambition: Smart, hard-working, humble, and not afraid to fail. Team-first but willing to take the lead with minimal guidance. • Material Security is a remote-first workplace with an office in San Francisco, California. • By clicking "Apply for this Job", you acknowledge that you have read the California Candidate Privacy Notice Regarding Use of Personal Information https://material.security/ccpa and hereby agree to its terms.
