We are a stealth-stage startup operating in the mobility sector.

We have our first customers, early traction, and are currently raising our pre-seed round.

The company is led by a repeat founder. We are looking for a technical co-founder to own everything engineering — from AI and data architecture to the product itself.

Tasks

Design and own the end-to-end data architecture: ingestion, storage, transformation, and serving layers
Build AI-powered systems including matching algorithms, dynamic pricing, demand forecasting, and route optimisation
Lead full-stack development of the platform, maintaining solid engineering standards across the codebase
Drive the ML/AI roadmap from early experimentation through to production at scale
Architect backend systems for reliability and scalability as transaction volume grows
Oversee API design and third-party integrations (logistics, telematics, payments)
Hire and build an engineering team as the company grows
Partner with the CEO on fundraising, due diligence, and investor conversations

Requirements

Must-Haves

3+ years in an engineering leadership or senior tech lead role, ideally at a fast-moving startup or scale-up
Strong background in data architecture and engineering: pipelines, warehousing, real-time streaming
Hands-on experience with ML/AI systems in production — not just prototypes
Solid full-stack fundamentals, comfortable going deep on backend and across the stack when needed
Fluent in English (written and verbal)
Based in Germany

Nice-to-Haves

Experience with logistics, marketplace, or two-sided platform products
Cloud-native architecture experience (AWS, GCP, or Azure)
Additional European languages (German especially welcome)

Mindset

You think in systems but you ship things
Hands-on and execution-focused — comfortable doing before delegating
High ownership, low ego
Energised by the early stage and what comes with it

Benefits

What You'll Get

Co-founder title and a meaningful equity stake
Competitive salary structured to reflect the stage
Full ownership of the technical direction from day one
High learning curve and fast execution cycles
The opportunity to shape a significant market from the ground up
