About the role

Hands-on (Senior) Security Engineer to strengthen the security of Langdock’s product, infrastructure, and internal systems, with a focus on application and infrastructure security, internal IT security, and customer/compliance support.

Responsibilities

  • Coordinate penetration tests end to end. Define scope with engineering and external testing partners, support testing, assess findings, and follow remediation through to verification.
  • Own vulnerability intake and triage. Monitor our security inbox and responsible disclosure program, assess reported issues, and work with engineering to prioritize and resolve them.
  • Help engineering build securely. Review security-sensitive designs and changes, identify weaknesses in areas such as authentication, authorization, and data isolation, and recommend practical improvements.
  • Assess and improve our security posture. Work with engineering to evaluate how our production infrastructure and internal systems are protected, identify gaps, and drive improvements.
  • Strengthen network and access controls. Review network separation, service exposure, privileged access, and permissions so systems and data are accessible only where needed.
  • Verify that controls work in practice. Look beyond configuration checklists to understand how systems could be compromised and whether our protections would prevent or detect it.
  • Own identity and device security. Ensure we have effective MFA, appropriate access policies, and properly managed, encrypted, and patched devices.
  • Automate the employee lifecycle. Build dependable processes for account provisioning, access changes, offboarding, and access reviews across Entra ID and our internal tools.
  • Keep recurring work manageable. Use scripts, integrations, and AI tooling to automate security operations and surface issues that need attention.
  • Support customer security assessments. Help answer questionnaires and join customer conversations that require a clear, technically credible explanation of our security controls.
  • Contribute to our compliance programs. Support our ISO 27001 and SOC 2 Type II work through effective controls, current evidence, and technical input into audits and risk assessments.

Qualifications

  • Hands-on application and infrastructure security experience.
  • Technical depth and sound judgment to investigate vulnerabilities and discuss remediation with engineers.
  • Experience taking findings through to resolution with penetration testers or vulnerability disclosure programs.
  • Confidence with identity and endpoint security, including configuring identity providers, MFA, access policies, and device management, plus automation.
  • Automation mindset with ability to build scripts, workflows, and integrations; thoughtful use of AI tooling.
  • Clear communication to explain technical risks and controls to engineers, colleagues, and customers; German is a plus but not required.
  • Pragmatism in prioritizing meaningful risk reduction and feasible controls.
