Your mission

Join our ranking team and build the intelligent systems at the core of Cosuno's platform.

• Ranking & Recommendation: Own and improve the systems that match the right subcontractors to the right tenders.

• 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.

• 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.

• Own the problem: Work directly with Product and Data to decide what to build, then build it.
