Cybersecurity Engineer

Your mission Are you passionate about technology with a purpose? Want to make a meaningful impact on people's health? At Relu, we're growing
- and we're looking for someone like you. We're looking for a Cybersecurity Engineer to own our Platform / Software security. You will:
• Build our ISMS from the ground up — scope, risk assessment, Statement of Applicability, and core policies — and lead us through ISO 27001 Stage 1 audit
• Get Vanta green across every system, with a live Trust Center that takes manual security questionnaires off sales' plate for good
• Run a penetration test and close every critical and high finding before it becomes someone else's problem
• Stand up vulnerability management across code, dependencies, containers, and Terraform — with a triaged backlog and fix deadlines that actually get met
• Harden our AWS and Kubernetes baseline with least-privilege access, network segmentation, and threat-detection piped straight to on-call
• Write and tabletop-test our incident response playbook, GDPR 72-hour breach notification included, and align it with our MDR technical documentation so we run one evidence set — not two

Your profile
What you should bring to the team:
• 2–5 years of hands-on cybersecurity engineering experience, including vulnerability assessment, threat modeling, and incident response
• Solid command of AWS security — IAM policies, network segmentation, secrets management
• Proficiency with security tooling: SIEM platforms, IDS/IPS, and penetration testing frameworks like Burp Suite or Metasploit
• Experience securing software development pipelines (SAST, DAST, dependency scanning) and working within a DevSecOps culture
• Working knowledge of compliance frameworks such as ISO 27001, SOC 2, or GDPR — ideally in a SaaS or healthtech context
• Ability to write and maintain security policies, runbooks, and incident response playbooks that people actually use The 'Nice-to-haves':
• Experience in a regulated industry — healthcare, medtech, or dental — with exposure to HIPAA or MDR requirements
• Familiarity with zero-trust architecture and modern identity solutions like Auth0
• Hands-on experience with container security (Docker, Kubernetes) and IaC scanning tools like Checkov
• Relevant certifications: CEH, OSCP, CISSP, or AWS Security Specialty How you work:
• You take ownership and bring a builder mindset — you're comfortable defining security practices from scratch in a fast-moving environment, not just maintaining what already exists
• You balance thoroughness with pragmatism — you know when to move fast and when the moment calls for slowing down and doing it right Why us?
• A mission that matters: we're improving dental care and making higher-quality dentistry accessible to everyone, globally
• A fast-growing company where your growth goes hand-in-hand with ours — real impact, real ownership, and skills in the technologies of the future
• A driven and collaborative team
• Fun team culture: after-works, bi-weekly sports, hackathons, retreats
