About the Team

Security Automation & Integration Engineering (SecAIE) transforms cybersecurity operations by architecting intelligent automation that turns manual processes into scalable decision-accelerating systems. Were the engineering excellence partner within Cybersecurity and Trust - building the unified data foundation intelligent automation and decision support tools that enable security teams to make precise data-driven decisions at machine speed.

We partner closely with Security Leadership Operational Teams Engineering Teams and Governance/Risk Teams to deliver platforms that multiply their effectiveness. Our current charter contributes directly to Workdays Active Defense pivot - building the reliable data and platform substrate that lets security teams execute at machine speed and out-adapt AI-driven threats.

Were a small high-impact team that values curiosity pragmatism and collaboration. We believe working solutions beat perfect designs unified context beats massive datasets and partner success is our success. Leveraging AI to augment how we do security engineering is an active opportunity for the team and one we expect this role to help lean into.

About the Role

Were looking for a Cybersecurity Engineer to join SecAIE and take primary ownership of the agent eval and application work that Workdays Active Defense charter runs on. Youll spend most of your time engineering the layer partners actually use - eval harnesses agent scaffolds schemas and application UIs on top of security data - so detection response and threat-intel teams can move from a vague ask to a working system. This role is ideal for someone who loves turning messy operational problems into clean reusable software who can walk into an ambiguous ask and come back with a proposal and who treats AI tooling as a force multiplier rather than a novelty.

You will bring working knowledge of cybersecurity concepts and best practices from day one - enough to reason about identity and access secrets handling and the shape of common security data (vulnerabilities incidents identity threat intel detections). You will not be expected to be the deepest security specialist in the room; you will partner with domain experts across our security organization and build the agents eval and applications that make their work faster more reliable and more measurable.

Responsibilities:

- Own agent-adjacent application work: eval harnesses agent scaffolds and the UIs that security partners use to inspect and act on results
- Design build and evolve schemas and data contracts so agents and humans share the same objects rather than one-off payloads
- Take partner requests from vague to shipped: scope the problem propose approaches choose one and drive it through design review rollout and operational readiness (eval tracing runbooks)
- Build and maintain integrations across security tools and enterprise platforms - SOAR SIEM vulnerability scanners ticketing - when the application or agent needs them
- Raise the teams AI-augmented engineering floor: shared skills reusable scaffolds a review discipline for AI-generated code and eval that catches drift
- Iterate quickly: prototype test ship learn improve - and bring the team with you

About You

Youre a curious engineer who owns problems rather than tickets. Youre drawn to ambiguous messy asks and you enjoy learning a domain deeply enough to propose the right solution not just implement one that was handed to you. You bring high agency: you can move a partners rough problem statement to a shipped operational answer without waiting to be told each next step. Youre comfortable turning a partners Slack thread into a written proposal and comfortable when the answer to whose ticket is this is nobodys yet - Ill draft one. You know when to escalate and when to just close the loop yourself. You default to reusable components over copy-paste eval over vibes and reliable defaults over one-off heroics. You use AI tooling deliberately and can articulate where it accelerates you and where it does not. You communicate clearly ask good questions and genuinely enjoy collaborating across teams to solve hard problems.

Basic Qualifications:

  • Strong Python skills with hands-on experience shipping production software (APIs services batch jobs or application backends) including code review testing and operational follow-through
  • Hands-on experience building or evaluating LLM / agent systems (harnesses eval tracing or agentic pipelines) or strong software-engineering fundamentals plus demonstrated AI-augmented development (Copilot coding agents) with a point of view on where they help
  • Comfort designing or evolving schemas / data contracts and application UIs that sit on real data - not mock-only prototypes
  • Working knowledge of core cybersecurity practices - identity and access secrets handling secure-by-default configuration and reasoning over common security data (vulnerabilities incidents identity threat intel) - so you can build for security outcomes.
  • Comfortable owning what you ship (runbooks basic observability eval that still runs after you merge)

Other Qualifications:

  • Agent / eval - LangChain LangGraph LangSmith or similar; LLM-as-judge or offline eval; tracing and observability for agent runs
  • Application / UI - frontend (React or similar) for internal tools; watchlist / dashboard / workflow UIs on security data
  • Security domain - hands-on with security tools or data for triage and investigation (SIEM vulnerability scanners identity systems orchestration platforms such as Tines); curiosity about detection-engineering workflows
  • Data / schema - comfort reasoning about shared schemas or data contracts that span team boundaries treating what / who / state as a first-class artifact
  • Cloud / platform familiarity - working AWS fluency (enough to ship and operate); IaC (Terraform/Docker) is useful but not the daily job
  • Comfort operating in ambiguous problem spaces where you help define the solution not just implement it
