As a Senior Security Engineer at Capmo, you will get to:

• own product and cloud security end to end — threat modeling, security reviews, secure-by-default patterns, and the tooling in our CI/CD pipelines (SAST, dependency and container scanning, secret detection) that keeps findings from piling up.

• harden our AWS infrastructure: IAM architecture, network segmentation, encryption, logging, workload security — and encode the baselines as policy-as-code instead of a wiki page nobody reads.

• build our detection and response capability from the ground up, and be the technical lead when something actually happens — from detection through containment to the post-incident review.

• own our vulnerability disclosure and pentest programs, and drive remediation with the product teams rather than filing tickets and hoping.

• back our compliance work (ISO 27001, SOC 2, GDPR) with real technical controls and evidence, and support customer security reviews together with Sales.

• shape the direction of security at Capmo as a hands-on senior IC — building guardrails that engineers adopt because they're good, not because they're mandated.

• Become a shareholder: Take part in our success with our employee stock option program (VSOP).
• Grow fast: Benefit from an annual development budget of €1,000 and two Development Days to invest in your personal and professional growth.
• Fitness, food or mobility budget? With EGYM Wellpass, you get unlimited access to 90+ gyms and swimming pools in Germany – or choose a lunch subsidy or a mobility budget as your preferred benefit. 
• Think ahead: We contribute 20% to your company pension plan. (only applicable in Germany)
• Hybrid work model: We work in a hybrid setup — 3 days together in the office and 2 days wherever you work best.
• Exceptional Team: Join a talented and diverse team with limitless growth opportunities.
• Culture Day Off: Take a day off for essential occasions.

• 7+ years of hands-on security engineering, including several years owning application and cloud security for a production SaaS platform end to end.

• A track record of building security programs — SDLC, vulnerability management, detection and response — not just operating tools someone else set up.

• Expert-level understanding of vulnerability classes and attack techniques well beyond the OWASP Top 10: you can threat-model a new feature, spot the subtle authz flaw in review, and explain the exploit path to the engineer who wrote it.

• Deep experience hardening cloud infrastructure at scale (AWS ideally, GCP or Azure fine): IAM, network segmentation, container security, security-as-code — designed by you, not inherited.

• Strong software engineering skills — you write production-quality code, build automation from scratch, and hold your own in architecture discussions with senior engineers.

• Proven incident response leadership: you've been the technical lead when things went wrong.

• The judgment to make risk-based calls under ambiguity, and the influence to get teams to act on them without formal authority.

• Excellent English; German is a plus. Willingness to be on-site 3 days per week in Munich or Berlin.

Nice to have: building up a security function in a scale-up, detection engineering, ISO 27001 / SOC 2 certification experience, certs like OSCP or CISSP (valued, but hands-on skills matter more).
