Senior AI Engineer
Cosuno
• Join our AI team and build the intelligent systems at the core of Cosuno's platform. • AI Agent Development: Build and improve our agentic system that orchestrates multi-step reasoning to navigate the complex, often messy tendering workflow. • Ship end-to-end into the product: Own features from model/agent through API to the TypeScript front-end — backend service, API, and the integration into the web app. • Ranking, Search & Retrieval: Iterate on the ranking and retrieval systems that power subcontractor matching and marketplace search. • Price Prediction: Improve models that estimate fair pricing for construction work, helping users evaluate bids and make better procurement decisions. • Experimentation & Evaluation: Design offline evals, run online A/B tests, and drive metrics-led iteration. • 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.
Job Requirements
- Strong Python: You have 5+ years writing production-grade Python. You write clean, well-structured code.
- TypeScript, React, Node: Non-negotiable. You're comfortable shipping into our web app end-to-end — front-end, backend service, API.
- End-to-end product delivery: You've shipped features (not just models) into a production web app and owned the integration from research code to real users.
- LLM application depth: You have deep hands-on experience building and deploying LLM/agent systems — RAG, tool use, multi-step reasoning, evals.
- Backend engineering skills: You design APIs, data pipelines, and services.
- 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: Comfort with 'classical' ML foundations
- Bonus: Experience building search/ranking/recommendation or price prediction systems
Benefits
- Fully remote team and work culture
- Freedom in your working hours. It's the results that count.
- Company off-sites and regular team events (offline and online)
- Flexible working conditions with the possibility to do workations
- Competitive compensation, a permanent contract, and modern work equipment
- Open feedback culture with regular 1-on-1s

Role Description We're looking for an Applied AI Engineer to drive AI implementation across our portfolio companies. This is a new role, and frankly, a new function. You won't find a playbook for this job because it doesn't exist yet. Your mandate: make sure our portfolio companies are actually using AI. Not talking about it, not "exploring" it, but deploying it in ways that move the needle. That means customer service automation, developer productivity tools, sales and marketing workflows, back-office operations, and whatever else makes sense. You'll work closely with the Managing Partner to identify opportunities, evaluate tools, and get things live. Then you'll train portco teams to own what you've built. Rinse, repeat, across every company in the portfolio. This is 80% hands-on implementation, 20% evaluation and planning. There's no playbook for this yet, at Emberline or anywhere else. The partners will be genuine thought partners as you build the function. The expectation is not that you arrive with everything figured out; it's that you're willing to figure it out alongside us. This is a high agency, high opportunity seat with the ceiling set by you. Key Responsibilities - AI Implementation - Operational Audits: Assess each portfolio company's workflows across customer service, sales, marketing, finance, and operations, then identify where AI can reduce friction, cut costs, or improve quality. - Tool Deployment: Configure and deploy AI tools (chatbots, copilots, automation platforms, etc.) across portco functions. - Workflow Integration: Connect AI tools to existing systems like CRMs, helpdesks, marketing platforms, and codebases. - Rapid Prototyping: Test new AI applications quickly. Prove value in days or weeks, not months. - Vendor & Tool Evaluation - Landscape Monitoring: Stay current on AI tooling: what's shipping, what's vaporware, what's actually production-ready. - Vendor Screening: Evaluate vendors, run trials, negotiate pricing. - Build vs. Buy Decisions: Know when to use off-the-shelf tools, when to customize, and when to build something custom. - Enablement & Knowledge Transfer - Team Training: Train portfolio company teams to use and maintain the tools you deploy. - Documentation: Build simple, usable guides for each implementation. - Cross-Portfolio Learning: What works at one portfolio company should benefit the others. - Partner Support - Weekly Syncs: Work closely with the Managing Partner to prioritize, troubleshoot, and align on roadmap. - Experimentation Partner: Test new tools and approaches alongside the Partner. Qualifications - Experience in Product Management, Solutions Engineering, Technical Operations, or similar roles. - Hands-on experience with AI/ML tools in a professional context. - Strong understanding of APIs, integrations, and how systems connect. - Excellent communication skills. - Comfort with ambiguity. - This is a remote role but on-site engagements, rapport building and investigations are a key requirement, which will require travel. First 90 Days - Audit the portfolio. - Get something live. - Build handoff documentation. - Establish a vendor shortlist. - Establish the working rhythm.
