Senior Full-Stack Engineer, Autonomous Defense

This is a fully remote position, open to applicants in United States.

📋 Description

• Develop and maintain the agent execution runtime featuring durable, resumable, long-term workflows, checkpointing, idempotent steps, cancellation, and timeouts.

• Design and implement the agent tool layer incorporating registry versioning, schema validation, per-tenant enablement, and server-side authorization.

• Create the connector framework for third-party security control planes, including EDR, firewall, identity, SIEM, and cloud IAM.

• Execute the safe-change pipeline with dry runs, simulations, blast-radius classification, approval gates, staged rollouts, rollbacks, and immutable per-tenant audit trails.

• Develop the operator-facing front end using React and TypeScript.

• Construct client-side data and streaming layers utilizing WebSockets instead of polling.

• Enhance tenant isolation for write-capable agents, which includes execution boundaries, egress control, quotas, and prevention of cross-tenant leakage.

• Create ETL and GraphQL product features for effective data processing and retrieval.

• Develop ETL pipelines that transform pentest and remediation outcomes into training and evaluation datasets.

• Instrument systems with distributed tracing, per-tenant cost and token accounting, along with tools to clarify agent decisions.

• Collaborate with AI researchers, attack engineers, and product teams to transition capabilities from prototype to production.
