As our first Software Assurance Engineer, you are the hands-on architect of our 'Secure Quality' program. This is a mission-critical, technical role to design, build, and operate our software assurance framework from the ground up. We believe that security and quality are not separate functions but are two sides of the same coin. Your mission is to architect and implement the automated tools (SAST, SCA, QA) and processes that empower our engineers to write secure, high-quality code from day one. This is a unique opportunity to be the founding 'builder-architect' who will embed a culture of mission assurance into our most critical products.

Job Responsibility

  • Build the Quality Framework: Architect, build, and maintain the frameworks for automated functional and regression testing
  • Manage Software Vulnerabilities: Lead the technical vulnerability management process for all in-house and third-party code
  • Drive Secure Coding Practices: Serve as the 'Security Champion' within engineering, providing expert consultation, training, and documentation
  • Support Product Security Compliance (CRA): Act as the technical lead for our compliance with the EU Cyber Resilience Act (CRA)

Requirements

  • 5+ years of hands-on experience in a technical role that blends Software Development, Quality Assurance, or Application/Product Security
  • Proven track record of building and implementing a secure SDLC
  • Hands-on experience selecting, deploying, and integrating AppSec tools (SAST, DAST, SCA) into a modern CI/CD pipeline (e.g., GitLab CI, Jenkins)
  • Demonstrable experience in designing, building, and managing automated QA testing frameworks (e.g., Selenium, Playwright, pytest, Robot Framework)
  • Proficiency in at least one programming language (like Python, Go, C++, or C#) and extensive scripting experience
  • Fluent and professional communication skills in English are mandatory
  • Proficiency in German is a significant plus

Nice to have

  • Experience in aerospace, defense, high-tech manufacturing, or OT/ICS environments
  • Familiarity with high-reliability or safety-critical software standards (e.g., DO-178C, MISRA C)
  • Experience securing containerized (Docker/Kubernetes) and cloud-native application environments
  • Professional certifications such as CSSLP, GWEB, or advanced QA certifications (e.g., CTFL)
  • Pragmatism and Drive
  • A Mission-Critical Mindset

What we offer

  • Employee Participation Program: Share in our success through our virtual company share program
  • 30 days of vacation
  • Company pension plan: Secure your future with our company pension plan, featuring a 20% employer contribution after the probation period
  • Subsidised lunch: Stay energised with delicious, subsidised lunches every day
  • Public transport ticket: Commute with ease using a fully financed Deutschlandticket
  • Sport Clubs membership: Stay fit with our sponsored sports club memberships (EGYM Wellpass)
  • Individual learning allowance: Grow your skills with an individual learning budget granted after the probation period
