Cosuno

• You own the marketplace dynamics between General contractors and Subcontractors on our platform. • You ensure a healthy balance between supply and demand, and build mechanisms that keep liquidity strong on both sides. • You own search, matching and recommendation mechanisms that bring Subcontractors and projects together in a way that increases relevance and bid rate. • You analyze marketplace metrics and translate them into hypotheses and priorities. • You identify AI use cases for matching and recommendations and implement them together with our designers and engineers.

• You independently own product responsibility for central areas of the general contractor product. • You identify new opportunities in the GC workflow: new user groups within the GC organization that we don't yet serve, or new steps in the tendering process that we can cover with our product. • You build complex B2B SaaS functionality end-to-end — from strategy and discovery to requirements definition and go-live — together with design and engineering. • You analyze user behavior, market trends, and product metrics to identify growth opportunities and translate them into strategic initiatives. • You develop hypotheses, validate them with prototypes and experiments, and scale successful approaches together with design and engineering. • Together with marketing and customer success, you ensure a successful go-to-market for new features.

• Take ownership of our dbt pipeline, improving our data models so they're reliable, well-tested, and easy to build on. • Maintain and extend our Looker setup, and ship new dashboards and reports that customers and other stakeholders depend on. • Strengthen our data pipeline from Postgres to BigQuery, and build custom Python scripts to automate the flows that keep our warehouse fresh. • Integrate our data warehouse with external tools like Salesforce or ActiveCampaign, so the right data reaches the teams that need it.

• Take ownership of our integrations product area — the REST API and our existing connectors to third-party systems such as RIB iTWO — and define where they go next. • Travel to customers across Germany to support them hands-on with implementing and setting up connectors, and to understand their systems, data flows, and constraints in the real world. • Sit down with customers to elicit integration requirements, then prioritize them against impact, effort, and our platform strategy. • Translate those requirements into clear, well-scoped tickets that our engineers can pick up and build — with the technical context they need to move fast. • Work through our API documentation and test endpoints yourself to validate what's possible, spot gaps, and represent the developer experience from the outside in. • Partner with Engineering, Customer Success, and Sales to make sure customers can connect their systems to Cosuno with as little friction as possible.

Role Description As our AI Automation Engineer, you will be the driving force behind scaling efficiency at Cosuno. As the expert for Cosuno’s automation stack, you will partner with teams across the company to identify, design, and implement AI-driven workflows that transform their work. Rather than building or training proprietary models from scratch, you will leverage state-of-the-art existing models and reasoning chains to solve business problems. As part of the product team, you will collaborate closely with the CEO & CTO to ensure all solutions are technically sound and aligned with our core infrastructure. This is an execution-heavy role where success is measured by the speed and reliability of the modular automation platform you build. Key Responsibilities - Discovery & Prioritization: Partner with Finance, Sales, Ops & Product to identify high-ROI automation opportunities & evaluate them based on business impact versus technical effort. - Workflow Engineering: Design, prototype, and deploy end-to-end AI workflows by building our orchestration stack (e.g., n8n, Vector Databases) and connecting various endpoints via APIs to build a universal memory for Cosuno. - Scaling & Modularity: Build solutions that are modular and reusable across different departments to avoid "reinventing the wheel" for every new request. - Enablement & Governance: Establish AI guardrails, while enabling AI champions in other departments to work with the automations themselves. - Monitoring & Optimization: Define and track success metrics (ROI, time saved, reliability) to ensure automations deliver continuous value. Qualifications - The "Product" Mindset: You treat internal tools like products. You prioritize ruthlessly and focus on business value over "perfect code” or "beautiful UI”. - Technical Fluency: You are proficient in Python, n8n, and API architecture. You have hands-on experience with RAG and connecting LLMs to proprietary data sources. - Applied AI Focus: You prefer building “Reasoning Chains” and integrating existing tools over training custom models. - Systems Thinker: You see the company as a series of interconnected data flows. You naturally see patterns and build modular solutions that scale across teams. - Change Agent: You have experience driving organizational change and can explain complex technical concepts to non-technical stakeholders with ease. - Pragmatic Innovator: You would rather ship a working automation in two weeks than a perfect one in six months, and you have the commercial sense to block non-feasible requests. Benefits - Applied AI, Not R&D: You won’t spend months training models that never go live. You’ll leverage the modern stack (LLMs, Vector DBs, n8n) to ship high-impact automations that solve real business problems immediately. - Uncapped Leverage: Construction is one of the last undigitized global industries. We aren't optimizing ad-clicks; we are building the digital nervous system for the physical world. Your efficiency gains here have a massive multiplier effect. - Strategic Ownership: You aren’t hidden in a silo. Collaborating directly with the CEO & CTO, you have the autonomy to identify bottlenecks and build the infrastructure that allows Cosuno to scale.
