ABOUT US

Expertise is the bottleneck in technical field service. We are building the AI that makes it scale – and learns from every visit, from every job.

- Stealth-mode AI venture building a copilot that guides technicians at every job like an experienced master craftsman – before, during and after every job

- Built in the field, not behind closed doors: our product is developed with direct access to thousands of technicians with a leading European real estate industry partner – every feature is tested on real jobs, with results in days instead of months

- Backed by Founders Factory; founding team in Berlin, MVP built and tested with technicians, now heading towards spin-out and first funding

- Vision: Europe’s leading field service intelligence layer.

THE ROLE

We have built and tested our MVP. Now we are looking for a hand-on Co-Founder & CTO who builds the technology and product that grows and scales the company.

WHAT YOU WILL DO

- Own the technology end to end: architecture, roadmap, build-vs-buy decisions, reliability and security

- Take the tested MVP to a production-grade product used daily by technicians in the field

- Build reliable AI workflows and repeatable integrations into customer systems such as work orders and asset data

- Continuously improve the Machine Learning core: retrieval over manufacturer and expert knowledge, multimodal input (photo, voice) and diagnostic reasoning

- Design and build the learning engine that makes the product smarter with every visit: capturing, reviewing, evaluating and reusing confirmed outcomes – the core of our knowledge moat

- Set up evaluation, safety and monitoring: expert-reviewed benchmark cases, grounding, escalation and regression testing

- Build a state-of-the-art UX/UI that technicians want to use every day

- Spend time with technicians in the field and turn their feedback into product within days

- Recruit and lead the engineering team as we scale

- Shape the company as a co-founder: strategy, culture and investor conversations alongside the founding team

WHAT YOU BRING

- Master’s degree in Computer Science, Machine Learning/AI, Data Science, Mathematics, Physics, Electrical Engineering or a related quantitative field

- Machine Learning experience, ideally 3+ years applying it in production products (e.g. LLMs, retrieval/RAG, NLP, computer vision, model evaluation)

- Entrepreneurial mindset: you want to build a company, not just a product – full ownership, bias for action and comfort with ambiguity

- Experience leading the technical build of a product from zero to one, e.g. as tech lead or founding engineer

- Strong hands-on software engineering across backend, APIs, data pipelines and cloud – you still build and ship yourself

- Sound technical judgement: you know the limits of LLMs, how to test them and when not to use them

- Product empathy: you enjoy learning from users in the field and making complex work simple

- Fluent German and English – German is needed for working with technicians and technical source material

NICE TO HAVE

- PhD in Machine Learning, NLP, Computer Vision, Information Retrieval or a related field

- Previous founder or early-stage startup experience

- Experience with Microsoft Azure and enterprise B2B requirements (security, GDPR, multi-tenant SaaS)

- Background in field service, industrial, maintenance or proptech software

- Experience with multimodal AI, voice interfaces or decision-support systems

- Experience hiring and leading engineering teams

WHAT WE OFFER

- Competitive compensation package, including a meaningful co-founder equity stake

- A true co-founder role with ownership of the technology and a real say in the direction of the company

- An unfair head start: a cooperating partner with thousands of technicians and real repair data from day one – the fuel for a system that learns from every job

- A tested MVP and a clear path to spin-out and funding

- Support from Founders Factory’s network across tech, design and growth

- A mission with real-world impact: helping close the skilled-trades gap in Europe

LOCATION & START

- Berlin / hybrid, flexible

- Full-time; start as soon as possible

HOW TO APPLY

- Send your CV or LinkedIn profile with a short note on why you want to build this company with us and an example of Machine Learning work you have shipped
