About the role

Key responsibilities & impact

Extend agent capabilities by adding investigation tools and integrations with security data sources
Improve how agents manage context, recall evidence, and balance cost against latency
Build evaluations to determine whether agents produce correct, well-sourced findings
Use evaluation results to guide model, prompt, and tool changes
Evolve service boundaries and failure handling as capabilities expand
Raise engineering standards for API governance, testing, and observability
Work with product management to turn case needs into technical specifications
Design and build hands-on as the platform grows
Provide technical leadership through design reviews, code reviews, and architectural decisions

Requirements

What you’ll need

Typically gained experience in a Staff, Principal, or Lead role
Taken AI agents from prototype to production across multiple model providers
Built tool-calling agent loops
Built evaluation harnesses that catch regressions before release
Built guardrails against hallucination
Use coding agents daily and review and verify their output
Deep expertise in Go or Python and strong proficiency in the other, including runtime, concurrency models, and memory management
Experience with relational systems of record, columnar analytical stores, and vector search
Experience with zero-downtime schema migrations
Designed schema-first, contract-driven APIs with generated clients and built-in validation
Built streaming APIs for live updates
Built long-running workflows using durable execution and event streaming
Treat idempotency, retries, and recovery from partial failure as design requirements
Experience building event-driven ingestion pipelines moving large volumes of structured data from object storage into analytical systems
Nice to have: experience with a major cloud provider, infrastructure as code, and container orchestration
Nice to have: designs that isolate each customer's or case's data
Nice to have: experience building security products or familiarity with digital forensics, incident response, or security telemetry
