Job Overview by Ladders

Qualifications

  • 5+ years in detection engineering or threat hunting experience in security operations organizations within cloud-native infrastructure, SaaS, or fintech.
  • Strong hands-on expertise with SIEM and EDR tools such as Splunk, Elastic, or CrowdStrike, including advanced query and pipeline tuning skills.
  • Proven ability to create detection logic linked to MITRE ATT&CK that has successfully caught real adversary actions.
  • Strong scripting and automation abilities, particularly in Python or SQL, with a focus on detection-as-code workflows including unit tests and rollbacks.
  • Ability to distinguish between ineffective alert rules and genuine issues, actively improving the quality of alerts.
  • Capability to operate independently and build processes as required in an evolving environment.
  • Excellent written communication skills, suitable for creating effective runbooks and incident reports.

Responsibilities

  • Lead the end-to-end detection engineering program, including threat modeling and detection design.
  • Develop detection-as-code pipelines with version control and robust testing.
  • Conduct threat hunting based on authentic adversary behavior and develop repeatable detection methods.
  • Manage the health of SIEM and EDR pipelines, ensuring quality alerts.
  • Oversee triage and response for alerts generated, documenting incidents comprehensively.
  • Automate processes to minimize manual workloads for incident response.

Benefits

  • Comprehensive health, dental, and vision insurance.
  • Generous paid time off and flexible work arrangements.
  • Opportunities for professional development and training.
  • Collaborative work environment promoting innovation and teamwork.
Full Job Description
The Security & Corp IT Team

The Security & Corp IT team protects the infrastructure behind the largest AI compute buildout in history, from corporate endpoints to the environments running frontier AI workloads.

Examples of key problems the team is working on:
  • Build detection and response coverage across corporate, cloud, and data center environments that are growing faster than any off-the-shelf playbook assumes.
  • Secure the systems and networks that frontier AI labs depend on, where downtime and compromise both carry real cost.
  • Stand up security tooling, identity, and endpoint management for a company that adds people, sites, and vendors every month.
  • Turn incident learnings and threat intel into durable detection logic instead of one-off fixes.
Role Scope
  • Own the detection engineering program end to end: threat modeling, detection design, deployment, tuning, and retirement, with coverage mapped to MITRE ATT&CK and gaps documented rather than assumed away.
  • Build detection-as-code pipelines so every rule is version-controlled, tested, and peer-reviewed before it ships, and false-positive rates are measured, not guessed.
  • Run threat hunts against real adversary behavior in our cloud, SaaS, and data center environments, and convert findings into repeatable detections.
  • Drive SIEM and EDR pipeline health: log source onboarding, normalization, and alert quality good enough that on-call responders trust what pages them.
  • Lead triage and response for the alerts you build, and close out incidents with root-cause writeups that change the detection stack, not just the ticket queue.
  • Build automation that removes manual triage steps, so the team's alert load scales slower than the company does.
What We're Looking For

The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
  • 5+ years in detection engineering or threat hunting inside a mature security operations org (cloud-native infrastructure, SaaS, or fintech).
  • Deep hands-on experience with SIEM and EDR tooling: Splunk, Elastic, CrowdStrike, or equivalent, including query languages and pipeline tuning, not just console use.
  • You've written and maintained detection logic mapped to MITRE ATT&CK against real adversary behavior, and you can point to detections that caught something.
  • Strong scripting and automation skills (Python, SQL, or similar) and a detection-as-code workflow you'd defend: tests, review, and rollback included.
  • You know the difference between a noisy rule and a broken one, and you tune or kill detections before responders learn to ignore them.
  • You operate well with minimal process: you can scope your own work, ship without a mature SOC around you, and build the process you need as you go.
  • You write clearly enough that your runbooks and incident reports work when you're asleep.
  • Bonus: experience securing physical infrastructure or OT/data center environments, purple team experience, or contributions to open-source detection content (Sigma, detection rule repos).


We are committed to pay equity and transparency.
