This is a fantastic opportunity to build and lead the security program at a mission-driven company focused on health technology. You'll have a high level of autonomy in establishing security frameworks and achieving certifications, with the chance to make a real impact.
Job description
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
About us
Relu is a Leuven-based AI start-up automating the 3D design of dental appliances - freeing up time, cutting costs, and improving global access to dental care.
We’re a team of 25 engineers, business and dental people who:
Learn fast
Own what we do
Get stuff done
We are actively growing our team and our technology evokes more interest every day, expect your role to evolve over the years!
