Lead Security Engineer (m/w/d)

What to expect as our Lead Security Engineer (m/w/d):

You'll be our first dedicated security engineer: a senior IC with no team at the start. You join as Deputy CISO, report to our Director of Technology (currently acting CISO), and build security engineering from scratch. The baseline is already in place – ISO 27001, C5 Type II, regular penetration tests, and encryption in the product. AI is adding new surfaces: voice documentation, document generation, and agentic workflows. You build and own the security program, the tooling, and the security story we tell customers.

• Vulnerability management – scanners and dependency updates across repos, plus the process that gets findings closed.
• Partner to Platform – review security-sensitive infrastructure decisions and explore options like customer-managed keys or HSMs. Platform still owns architecture.
• Certifications, technical side – control design and assessments for our ISO 27001 and C5 setup, the security case for a potential upcoming Class IIa medical device (MDR), and pentest scoping and follow-up, with regulation like the EU Cyber Resilience Act on the horizon. This is roughly a quarter to a third of the role, and we say it openly: for the right person in healthcare security, it's a draw, not a chore.
• Customer security – reusable docs, evidence, and AI-assisted questionnaires, so the tenth enterprise deal costs a fraction of the first. You join the call when a hospital CISO asks something new about our AI architecture.
• Incident response – process, runbooks, and escalation, and you lead when it's real. We're too small for a SOC, so you design on-call that fits a company our size. Product incidents and platform bugs have their own owners in engineering.
• Company-wide security – watch the threat landscape, turn this week's supply-chain mess into concrete actions, and set the baselines IT applies to devices and accounts.

How we work:

• You're a hands-on security engineer with 6+ years across software and security engineering, and you can point to a security program (or a big part of one) you've owned.
• You've been the technical counterpart through at least one ISO 27001, C5, or SOC 2 certification cycle: you've designed controls, faced an auditor, and written the technical side of a Statement of Applicability. This is a hard requirement.
• You've run vulnerability management somewhere real: scanners, dependency bots, triage, and the follow-through that gets things fixed.
• You follow the security scene closely (podcasts, advisories, incident write-ups) and usually have an opinion on this week's incident before it reaches the news.
• You're genuinely curious about AI security – both securing AI systems (agents, sandboxing, data flows) and using AI tooling to work at leverage.
• You can talk to engineers, auditors, and hospital security teams in English without a slide deck translating for you.

Nice to have:

• German language skills, since our customers and the C5 world are German-speaking.
• Experience in healthcare or another regulated domain.
• Offensive security experience.
• Security certifications such as OSCP, CISSP, or similar.
