Staff Software Engineer, Secure Execution Platform

Harvey; San Francisco (CA); On-site; USD 231,000 - 346,000; Full time

Job summary

Harvey is hiring a Staff Software Engineer for the Security Engineering team in the SF area. You will found the security foundations enabling AI agents to work securely, building execution environments, orchestration, and controls across product and internal platforms.

You’ll shape architecture, ship production code, and establish reusable security capabilities that scale with the company’s growth. This is a founding team role with ownership from design through rollout.

Qualifications

• 10+ years developing and running production software.
• Strong software engineering skills in Go, Rust, Python, or C++, with Linux systems, networking, and containerized infrastructure.
• Deep expertise in one or more areas of execution security, such as sandboxing, OS isolation, container security, or trusted execution environments.
• Experience building shared platforms, services, or libraries and helping teams adopt them via clear interfaces and migrations.
• Experience with cloud infrastructure and distributed systems, including observability, failure handling, capacity management, and dependable production operation.
• Fluency with AI-assisted engineering and agentic workflows: you use models to accelerate development, validate output, and assess risks when agents use tools, execute code, or access data.
• Strong communication and technical judgment, with a track record of consensus on complex problems.

Responsibilities

• Set the technical direction for secure agent execution, coordinating across Security, Infrastructure, and Product Engineering to translate capabilities and risks into a roadmap.
• Design, build, and operate a platform for security agents to discover and validate vulnerabilities within authorized targets and execution boundaries, producing reproducible evidence for engineers.
• Build reusable controls for agent tool use, code execution, network and filesystem access, resource consumption, and workload lifecycle; integrate with identity and secrets platforms to limit data access.
• Partner with Harvey’s product sandbox and internal agent platform owners to make architectural decisions, implement protections, and share security capabilities.
• Enable internal use of open-source models alongside infrastructure teams with protections around model serving, agent execution, and sensitive data handling.
• Develop adversarial tests, evaluations, and telemetry to verify containment and expose failures; build mechanisms to scope, observe, interrupt, and safely terminate agent activity.
• Lead delivery and adoption across teams, mentor engineers, and stay hands-on through implementation and production operation, balancing security, reliability, latency, and cost.
