AITIGRITY covers the full product security lifecycle, from threat analysis and risk assessment (TARA) through security requirements, secure coding checks and testing to vulnerability monitoring. It runs on our customers' own infrastructure and works with interchangeable language models. As a Senior Software Engineer you design and build features across the platform, from the user interface to the APIs, data model and AI-supported analysis, and you help shape its architecture as we grow.

• Design, build and maintain full-stack features of the AITIGRITY platform, from user interface to back end and APIs.
• Integrate language models into security workflows such as threat analysis, requirements generation and test case creation.
• Make the platform robust for installation on customer infrastructure, including updates and data protection.
• Write clean, tested and secure code, and review code with the team.
• Work closely with our security consultants to turn real customer projects into product features.

• Several years of professional experience in full-stack development of web applications or SaaS products.
• Solid knowledge of front end, back end, APIs and databases, and experience with automated testing and CI/CD.
• A security mindset: you know common web vulnerabilities and how to avoid them.
• Experience integrating language models or other AI services is a strong plus.
• Knowledge of ISO/SAE 21434, IEC 62443 or the Cyber Resilience Act is a plus, but not required.
• Good English; German is a plus.

• Work on a product and on consulting projects, and see both worlds of cybersecurity.
• Real ownership in a small team, with direct influence on product and company direction.
• Continuous learning, with certifications and training.
• Flexible, remote-friendly work, based in Frankfurt am Main.
