Chief Technology Officer jobs in Germany

This is not a salaried position. We are looking for a Partner.

WiNGBELS is an IT & Digital Innovation House evolving from its roots as a Marketing & Advertising agency in Prague into a forward-looking technology startup based in Germany. We combine technology, design, and sustainability to build SaaS products with real-world impact.

We are currently developing multiple platforms, including an HR & Enterprise SaaS solution, supported by Microsoft Azure Sponsorship and partnerships with AI xpress Innovation Center and Softwarezentrum e.V.

An MVP is already in progress, with solid front-end and back-end codebase, and we are preparing for accelerators and funding rounds. So you will play a very important role of ensuring a high quality code to move the product from DEV/Test phase to PROD.

We are looking for a CTO / Co-Founder who wants to co-build, not just advise. You will own the technical vision, architecture, and execution, and grow with the company from MVP to scale.

This role is ideal for someone who:

• Is a highly motivated, entrepreneurial engineering leader and a genuine builder at heart
• Enjoys turning early-stage chaos into structured, scalable systems
• Wants real ownership and long-term impact, not a 9–5 job
• Does the job with Confidence and openness.

What you’ll do:

• Define and own the technical vision and architecture
• Lead the transition from DEV/TEST → production
• Make key decisions around scalability, security, and cloud cost efficiency
• Act as hands‑on architect & lead engineer while mentoring a small team
• Shape the product roadmap with the founder
• Establish DevOps, CI/CD, monitoring, and deployment standards
• Ensure security, GDPR compliance, and best practices
• Identify and resolve technical challenges and issues as they arise during development and deployment.
• Maintain comprehensive documentation for code, architecture, and deployment processes.
• Support fundraising and partnerships by translating tech into business value

Qualifications:

• Strong expertise in software engineering and system architecture
• Ability to translate ideas into working full‑stack solutions
• Strong expertise with modern stacks, for example: Databases (PostgreSQL, MongoDB), Java / Spring Boot, React (TypeScript), Python/FastAPI, REST/GraphQL, Azure services, OpenAI, Keycloak
• Practical DevOps expertise (Docker, CI/CD, Kubernetes or GitHub Actions)
• Strong security awareness (OWASP, GDPR, SOC2, modern authentication systems)
• Startup mindset: ownership, pragmatism, resilience
• Familiarity with GitHub, Jira, and Confluence

You do not need to know every tool listed. What matters most is architectural thinking, execution ability, and engineering judgment, not over‑reliance on AI tools.

Education & Experience:

• MSc/PhD degree in Computer Science, AI/ML, Engineering, or equivalent with hands‑on experience in building and scaling software systems.
• Graduated students are welcome to apply.

Languages:

• English (strong)
• German is a plus, not a blocker

Strong pluses

• Experience with RFID, NFC, QR codes, or IoT technologies
• Prior founder or early‑stage startup experience
• French language skills

No fixed salary at the start — instead:

• Recognition as a Chief Technology Officer (Co‑Founder), with influence on strategy and direction.
• Equity participation (starting range 3–8%), with a clear path to grow based on performance, impact, and long term commitment.
• Profit sharing / bonuses tied to product success
• Competitive salary once funding is secured
• Microsoft Azure Sponsorship + strong innovation ecosystem backing
• A rare chance to shape technology, culture, and strategy from day one.
• Opportunities for professional development and continuous learning.

We are an equal‑opportunity employer and value diversity. We consider all applications equally regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, or gender identity.
