Key Skills for This Role
Full Job Posting
Key Responsibilities:
Build and own deeply technical security improvements across our Cloud Infrastructure(s) and associated territory (AWS/GCP, Kubernetes, CI/CD), including shipping production changes yourself when needed.
Design, implement, and iterate on detection and response capabilities (SIEM, EDR/MDR, cloud-native detections, CNAPP) with an engineer’s bias for automation, reliability, and measurable outcomes.
Hunt, investigate, and respond to security alerts and suspicious activity end-to-end (triage → containment → eradication → recovery → learnings), including writing tooling and detection logic to prevent recurrence.
Build internal security tooling and automations (IaC, scripts, integrations) that reduce toil and raise the security bar by default.
Experience & Qualifications:
You’re a deeply technical security engineer with a builder/hacker mindset, able to go from idea → prototype → production and comfortable making changes directly in Cloud Infra / DevOps systems.
You have 5+ years of hands-on security engineering experience, ideally in a cloud-first SaaS environment.
Have worked in a fast-growing startup, scale-up and/or SaaS company
We would expect you to have experience in:
Cloud security engineering in AWS and/or GCP, with the ability to implement improvements hands-on (IAM, networking, compute, storage, logging).
Kubernetes security (cluster hardening, workload isolation, runtime security, policy controls) and container ecosystems.
DevOps fundamentals: CI/CD security, secrets management, artifact integrity, and secure-by-default platform patterns.
Incident response and investigation, including creating repeatable playbooks and automating response where appropriate.
Strong programming/scripting ability (Python or similar) plus comfort with infrastructure-as-code (e.g., Terraform) and automation.
Serious agent coding - ideally you’re on the bleeding edge in the space.
Endpoint security tooling, such as CrowdStrike
Bonus points for:
Hands on experience with any/all of: Hunters, Wiz, Falcon, Tracebit, Torii, Okta, Google Workspace, StrongDM, Github, StepSecurity, Dope Security
Any relevant Information Security certification, e.g AWS Certified Security, GIAC GWEB, OSCP, or CSSLP.
