Software Security Architect/Engineer (m/f/d)
Shape the digital future with us as a Software Security Architect/Engineer!
We develop tailored enterprise solutions for our customers using modern technologies and AI—from the initial idea through to operations. Your contribution directly impacts the success of our projects.
We are the S&N Group —a team of IT professionals passionate about developing software, shaping projects, and driving innovation. Whether consulting or development, AI, Java, or SAP—we bring technology, team spirit, and ideas together. We advise and support our customers in banking and public administration throughout every phase of digital transformation.
And we are looking for you as a Software Security Architect/Engineer (m/f/d).

What I like about S&N: being able to work autonomously, the open-door policy, and direct contact with the customer.

Your responsibilities
- As a Software Security Architect/Engineer, you embed security in the architecture: you derive security requirements from business objectives, establish Security-by-Design principles, and document and represent architectural decisions.
- Methodical threat modeling: systematically identify threats, abuse paths, and risks; derive and prioritize risk treatment.
- Secure Software Development (SSDLC): integrate security throughout the development lifecycle—from requirements, design, and implementation through testing to operations (shift-left, automated checks, Definition of Done/Ready).
- Cryptography & post-quantum readiness: assess cryptographic decisions, ensure crypto agility, and prepare roadmaps for post-quantum migration (e.g., hybrid approaches, key/certificate lifecycle).
- Architecture reviews & guidance: conduct design and code reviews with a security focus, curate patterns & anti-patterns, and develop reference architectures and guardrails.
- Business context & governance: translate security requirements into business value (risk/cost-benefit trade-offs), define security KPIs/OKRs, and align with compliance/data protection.
- Enablement & leadership: provide technical leadership in cross-functional teams, coach engineers/architects, and prepare knowledge for the company’s projects.
