Senior Security Engineer

Senior Security Engineer - US

Exploitation prevention is only as strong as the intelligence driving those efforts, and most of the industry is still running on intelligence that lacks exploit context. Vuln Check, The Exploit Intelligence Company, delivers structured exploit intelligence on what is actively weaponized in the wild, purpose-built for the data lakes, ETL pipelines, automation, and AI and LLM workflows your infrastructure already runs on, raising the capability of everything it powers.

We're hiring a Senior Security Engineer to work side-by-side with our engineering team, embedding security into how we build and ship — not bolting it on after the fact. You'll partner with engineers on design reviews, help harden the platform as it grows, and build the tooling and automation that lets security scale without slowing anyone down. You'll report to our VP of Information Security and have real autonomy to identify problems and build the solutions yourself and in collaboration with engineering.

This is a builder's role. In addition to use of vendor tools, you'll be writing code and infrastructure that turns security and compliance work into repeatable, self-service processes for the business helping to automate and improve what's manual today, closing gaps in how we detect and respond to issues, and giving engineering the guardrails and feedback loops they need to move fast safely.

• Work directly with engineering on design and architecture reviews, threat modeling, and secure-by-default patterns for new services
• Review and harden IaC across our cloud environments (EKS, Aurora, Open Search, S3, IAM)
• Lead least-privilege IAM decomposition and drive adoption of stronger identity patterns across the platform
• Support disaster recovery testing and resilience exercises alongside the infrastructure team

• Design and build automation that turns detection, response, and compliance work into repeatable processes rather than manual effort
• Improve and extend onboarding/offboarding automation, alert triage pipelines, and identity/access anomaly detection
• Build internal tools that give engineering fast, self-service ways to check their own security posture

• 5+ years in security engineering, with real depth in AWS security and Infrastructure-as-Code (Terraform/Terragrunt strongly preferred)
• Firm working knowledge of Kubernetes/EKS security — RBAC, network policies, pod security standards, image scanning, and cluster hardening
• Strong written communication — you'll document your own work, since we're a small, high-trust team
• A track record of building tools or automation that solved a security problem at scale, not just running existing tools
• Previous use of tools like Crowdstrike, Wiz, Security Hub
• Experience with golang
• Comfortable working directly with software engineers — in code reviews, design discussions, and incident response
• Incident investigation and RCA tracking
• Experience supporting a SOC 2 (or similar framework) program from the technical/evidence side
• Experience with Google Workspace as an identity/IdP source of truth
• Self-directed: you'll often be the only engineer working a problem end to end

• Exposure to offensive security or red/purple teaming
• Familiarity with Aurora or managed Open Search specifically

We believe people do their best work when they feel supported, trusted, and valued. Vuln Check offers benefits designed to meet a wide range of needs and lifestyles, tailored to your country of employment:
