Full Job Description

📋 Description

• As our Staff Application Security Engineer, you'll be the specialist behind application and product security for a platform of autonomous agents that plan, decide, and act on behalf of enterprise customers.
• This is a new threat surface, and the established AppSec playbook still applies to our product, our APIs, and our production environment but stops well short of the harder questions.
• Enterprises won't hand real work to agents they can't trust, making security a reason customers choose our product, and we invest in it accordingly.
• You'll migrate access control to the new model, close any gaps, and secure the product surface: authn/authz, API security, input and output handling, supply-chain risk.
• You'll build the guardrails that let agents act safely: permissions, attribution, sandboxing, tool-use limits, prompt-injection defence.
• You'll establish least-privilege access across production and make the secure path the fast path.
• Longer term, you'll take us towards an autonomous security team: agents that continuously scan the platform and the code we ship, and help remediate what they find.

🎯 Requirements

• A view on agentic security: you've thought about what security means when agents do the work, not humans.
• AppSec depth on a production platform: authn/authz, API security, secure design and review, supply-chain risk.
• Hands-on ownership: you'd rather fix it, than assign it.
• Systems thinking: you can talk through how an end-to-end autonomous system should be designed, and where it breaks.
• The basics for our stack: TypeScript, AWS, MCP, and AI engineering fundamentals - tool use, context, evals.
• Comfortable building with agents: it's how the whole team works.
