Role Overview Apollo is looking for a startup-minded Engineering Manager to lead our Security Detection & Response team. You'll build and scale a team that ships detection systems, automations, and investigation tools at startup velocity—moving from concept to production in weeks, not months. This is a hands-on leadership role for someone who can coach engineers, make fast decisions with incomplete information, and stay close to the technical details while balancing speed with rigor. This role operates in a fully remote environment and requires excellent asynchronous communication, comfort with ambiguity, and the ability to ship fast and learn from what sticks. Key Responsibilities Team Leadership & Engineering Culture Build, lead, and retain a high-performing remote Security Detection & Response team with clear expectations, strong onboarding, documentation, and knowledge-sharing practices. Coach engineers to grow in technical depth, operational ownership, and leadership capability while prioritizing shipping velocity and iteration over perfection. Define team culture around experimentation: ship detection rules quickly, measure effectiveness, iterate based on signal. Partner closely with Engineering, Infrastructure, IT, Fraud, Legal, People, Support, and Product—translating security risk into business decisions and communicating impact clearly to both technical and non-technical stakeholders. Shipping Detection Systems & Content at Startup Velocity Define and evolve the Security Detection & Response strategy: what to build, when, and why. Prioritize ruthlessly; not every threat gets a detection. Lead the team in shipping detection rules, MITRE ATT&CK-aligned use cases, investigation playbooks, and response automations with measurement and validation loops—but ship first, perfect later. Oversee Panther detections and AI-assisted workflows for triage, enrichment, and response. Continuously measure coverage, precision, latency, and tuning effectiveness through safe rollout and
