About the role

  • Cybersecurity generates more signal than any human team can process.
  • The AI Engineer's job is to change that.

Responsibilities

  • DAG Design & Pipeline Orchestration
  • Design and implement the DAG-based pipeline architecture. Decompose complex cybersecurity workflows into well-scoped pipeline stages and define data contracts between them.
  • Build the retrieval and enrichment systems that feed agents the context they need: structured lookups, vector search, tool calls, API integrations, or database queries.
  • Design routing logic that directs incoming data to the appropriate pipeline entry point or agent branch.
  • Design and build individual agents with well-scoped, production-ready prompts tailored to specific cybersecurity tasks (e.g., alert classification, entity extraction, severity scoring, false positive filtering).
  • Monitor pipeline performance end-to-end in production - latency, accuracy, cost, failure modes, and per-stage quality - and drive continuous improvement across all layers.
  • Build and curate labeled datasets from production telemetry for evaluation, regression testing, and fine-tuning purposes.

Requirements

  • 5 years of experience building and deploying production services end-to-end.
  • Hands-on experience with LLM APIs (e.g., OpenAI, Anthropic, Gemini) and prompt engineering techniques.
  • Experience designing and implementing DAG-based workflows or pipeline orchestration systems.
  • Familiarity with data retrieval patterns: vector search, structured queries, API integrations, and context assembly for LLM consumption.
  • Ability to work with unstructured or semi-structured data in a security or operational context.

Nice to have

  • Background in cybersecurity, SOC operations, or threat intelligence.
  • Experience with evaluation frameworks (e.g., RAGAS, LangSmith, custom harnesses).
  • Familiarity with fine-tuning, RLHF, or model distillation workflows.
  • Exposure to agentic frameworks (e.g., LangGraph, CrewAI, AutoGen, or custom implementations).
  • We're a startup and we make decisions quickly.
