Why you can actually get this job
The posting explicitly states 'Fully remote team and work culture' with 'Freedom in your working hours' and no geographic restrictions beyond the Berlin-listed HQ. The source-provided metadata indicates worldwide scope with no country exclusions. While the company is Berlin-based, the posting makes clear this is a fully remote role with no physical presence requirement, and no work authorization, language, or timezone constraints are stated.
“Fully remote team and work culture”
Physical presence — Explicitly affirms no physical office requirement; 'fully remote' contradicts any hybrid/in-office implication.
“Freedom in your working hours. It's the results that count.”
Physical presence — No timezone or synchronous overlap requirement is imposed; results-based, asynchronous culture.
“Flexible working conditions with the possibility to do workations”
Work authorization — Reinforces geographic flexibility; workations imply no residency or location lock-in.
“Source-provided allowed countries: (none — worldwide)”
Geographic scope — No country restrictions stated in source metadata; worldwide hiring scope by default.
Your mission
- Join our AI team and build the intelligent systems at the core of Cosuno's platform.
- AI for Construction: Take new models and AI capabilities from idea to production — design, train, evaluate, deploy, iterate — and own them end to end.
- Price Prediction: Improve the models that help users evaluate bids and make better procurement decisions, trained on millions of price data points.
- Ranking, Search & Retrieval: Iterate on the systems that match the right subcontractors to the right tenders.
- Experimentation & Evaluation: Design offline evals, run online A/B tests, and drive metrics-led iteration.
- AI Agent Development: Build and improve our agentic system that orchestrates multi-step reasoning to navigate the complex, often messy tendering workflow.
- Ship into the product: Take your work all the way to real users — model, backend service, API, and the integration into our TypeScript web app.
- Collaborate across teams: Work with Product, Engineering, and Data to translate business problems into shipped ML/AI features.
- Maintain production ML & AI: Monitoring, alerting, and continuous improvement of everything we deploy.
Your profile
Strong ML & deep learning background: You have 5+ years building, training, and shipping machine learning models — classical ML and deep learning — in production. You're fluent in a modern deep learning framework, ideally PyTorch.
- Strong Python: You have 5+ years writing production-grade Python. You write clean, well-structured code.
- LLM application depth: You have deep hands-on experience building and deploying LLM/agent systems — RAG, tool use, multi-step reasoning, evals.
- Experimentation rigor: You know how to evaluate models properly — offline metrics, online A/B tests — and let the data decide.
- TypeScript, React, Node: You're comfortable shipping your work into our web app — backend service, API, and front-end integration.
- End-to-end product delivery: You've shipped features (not just models) into a production system and owned the path from research code to real users.
- Product mindset: You're comfortable with ambiguity and can judge when something is good enough to ship.
- Sharp problem solver: You look at a complex system, quickly identify what matters, and decide what to do next.
- Bias for action: When you're unsure something will work, your instinct is to find out with data rather than keep wondering.
Bonus
- Experience building search/ranking/recommendation systems or pricing models
- Experience with embedding models, fine-tuning, or model training at scale
- Domain exposure to construction, procurement, or marketplaces
