The ideal candidate has a deep, technical background in hands-on incident response and a keen eye for where automation can improve and scale our capabilities. You are a natural problem-solver who remains composed under pressure, a senior team member who enjoys mentoring others in the craft of incident response, and a builder who can create the playbooks, scripts, and processes needed to protect our company and our customers. Between incidents, you'll build the tooling and workflows that make the next one faster and easier to handle.

SKILLS YOU BRING - 5+ years of experience in the Cybersecurity domain. - 3+ years experience being an Incident Manager, taking ownership of investigations. - Ability to lead a team during high-stress situations, providing direction and support to team members. - Understand how to turn noise into signals using a SIEM. - Proficiency with AI coding (Claude Code, Cursor, ChatGPT etc). We invest in tooling (automation, Slack bots, AI agents) so responders spend their energy on the decisions that matter. - Thinks in workflows: can look at a messy, recurring problem and break it into steps that tooling or AI can take on. - Knowledge of and familiarity with cloud infrastructure. - Believes that honesty, transparency, and inclusivity are important when communicating with both internal and external stakeholders. - Demonstrates good judgment under pressure both in terms of technical problem solving and collaborating cross functionally. - Eager to learn from the team and others.
