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
