Founding Engineer for Security Tech Startup

We are Sebastian Seifert , Andreas Veller , and Achim Bönsch – all graduates of the WHU Bachelor Class of 2011. After 13 successful years building the fintech company viafintech and ultimately selling it in one of Germany’s largest fintech exits for a nine-figure amount, we are now pursuing new challenges:

We found new ventures and invest in startups and venture capital funds.

For one of our portfolio companies, the SecureTech startup Novosafe, we are now looking for a Founding Engineer who is excited to shape the technical foundation from day one and take on a key long-term role in the company.

About Novosafe

Novosafe is a security technology startup tackling one of the last large B2B/B2C markets still surprisingly underserved. We’re building a modern, SaaS-style solution in a space with:

• High demand and low competition
• 10+ year customer retention
• Strong monthly recurring revenue potential
• A massive playground for technological innovation

Positioned at the intersection of strong unit economics and exceptional technical execution, we are creating a product that is both indispensable and designed for long-term market adoption.

Tasks

We’re looking for a Founding Engineer who’s excited about shaping a company from the ground up—not just writing code, but defining the technical foundation of our product and business.

You will:

• Lead technical decision-making and choose our tech stack
• Design and build our backend infrastructure and APIs
• Create initial product interfaces to connect with diverse hardware (e.g., a Novosafe API that integrates multiple supplier APIs)
• Lead app-development inhouse or with external partners
• Lay the foundation for a scalable platform that can handle growth for years to come
• Work closely with the founders to define the product roadmap and align engineering with business strategy
• Potentially grow into the CTO role as the company scales

Requirements

We’re looking for someone who:

• Has deep experience with backend systems , infrastructure, and API design
• Thrives in early-stage environments where speed and adaptability are key
• Enjoys solving complex technical challenges with an eye toward scalability and maintainability
• Is comfortable working in-person with the founding team in Berlin (not full-time remote)
• Wants to take ownership —both in equity and in decision-making

Benefits

• Early equity in a venture-backed pre-seed startup with paying customers
• Direct path to a CTO position
• Founders and investors with proven track records in building and scaling companies
• A rare opportunity to build the tech and the company at the same time
• Big, undersaturated market with room for innovation

Compensation: €50–60k salary + equity (pre-seed); substantial salary increase after next funding round (planned Q1/Q2 2026)

Location: Berlin, Germany (on-site preferred, with flexibility)

Start date: ASAP

MVP timeline: 3–6 months
