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
