About The Role

As a Security Response Engineer, you’ll lead our detection engineering efforts and the infrastructure that powers it, while contributing to Threat Management’s shared operational duties (preventing, detecting, and mitigating security incidents; building and triaging detections). You should have familiarity with a variety of detection engineering related projects. You would be working on designing logging and alerting pipelines to collect/filter/enrich logs in a scalable manner, building and deploying security-related tooling to gather new types of telemetry, setting standards for infrastructure use across the team, and collaborating with Eng/Infra teams to improve visibility and achieve shared security-related goals.

Your Impact

• Own detection engineering as a product: set the roadmap and drive measurable outcomes

• Build and run telemetry pipelines

• Establish team-wide standards: lead the standardization of internal security tooling, infrastructure deployment strategy, and access methods

• Proactively identify and implement areas of improvement and modernization

• Shape our EDR/SIEM strategy: act as a key stakeholder in evaluations, migrations, and architecture decisions

• Join the team's on-call rotation to assist in writing, tuning, and triaging detections, as well as coordinating the response to security incidents

Requirements

• Experience leading detection engineering efforts (logging pipelines, enrichment/automation, quality monitoring): owned the roadmap and delivered measurable outcomes.

• Hands‑on experience managing and deploying security infrastructure and tooling (IaC, containerization, remote access).

• Track record of authoring and tuning detections across endpoint, cloud, identity, and/or network telemetry.

• Operational rigor: served in a security on‑call rotation and acted as incident coordinator for high‑severity events with multiple external stakeholders

• Led a cross-functional initiative to ship a security-related capability.

• Previous coding experience (Python, Go, Rust, or similar).

Preferred Requirements

• Prior success in remote-first environments.

• Experience with detections‑as‑code (Sigma) development and workflows.

• Domain experience with blockchain/Web3 threats.

• Open-source contributions to security related projects.
