AI Agents Engineer (Hybrid)

## About the role Granter is building an AI agent that handles grants end-to end. The AI Grant Consultant helps companies discover funding opportunities, draft stronger proposals faster, and manage funded projects after approval. Our mission is to enable businesses of all sizes to leverage incentives to grow and innovate. We are deeply involved in the Portuguese startup ecosystem and were the winners of the Web Summit Pitch Competition 2025. We are now looking for an AI Agent Engineer. Not a backend engineer working on deterministic, predictable systems. Not a research engineer focused on advancing models. You should have already shipped something agentic, not just integrated an LLM. ## What This Role Involves - Be part of the tech team, working closely with engineering, product, and leadership and building features end-to end - Take ownership of problems and move them forward without waiting for perfect specs - Take decisions, not just implement. You will help define how things are built - This is not a "just ship tickets" role. We expect engineers to stay close to the problems and product outcomes, not just code - Build AI agents in practice and integrate them into real product flows - Use AI as part of your development workflow. We welcome it as a tool to move faster, not a replacement for engineering judgment ## What We Are Looking For We care more about evidence than years, but some fundamentals matter. You should have strong software engineering fundamentals and real hands-on experience building with LLM-based systems. ### Experience - 3+ years in software development - 1+ year specifically building AI agents ### Additional Plus - Experience using AI-assisted development tools effectively (e.g. GitHub Copilot, Claude Code, Cursor) is a plus - Degree in Computer Science, Software Engineering, or a related field is a plus - Experience working in a startup environment ### Core Skills - Strong Python skills, including async/await, and solid backend fundamentals - Hands-on experience building *AI agentic systems* (RAG, tool calling, memory, orchestration, etc) - Hands-on experience with LangChain and LangGraph including LLM providers, model trade-offs, prompt tuning, tools, chains, and structured outputs - Good engineering hygiene, including Git, CI/CD, and testing practices ### Nice to have - AG-UI or similar - Django - Celery - Docker - Azure ### Communication - Clear and direct communicator - Fluent in English and Portuguese - Able to explain technical decisions and tradeoffs - Can write good prompts (yes, this goes as a communication skill) ### Mindset - Strong ownership and ability to move problems forward without waiting for perfect specs - Comfortable working with non-deterministic systems and iterating until the solution works in practice - Motivated by building in a startup environment and being close to product and real-world impact ## How We Like to Work We aim to build a team of high-agency builders - people who take initiative, move problems forward, and don't wait for permission to improve things. You'll likely do well here if you: - Take ownership - Focus on outcomes, not just outputs - Move ideas forward quickly through testing and iteration - Communicate clearly and give direct, no-B.S. feedback - Collaborate effectively across disciplines - Stay comfortable operating in ambiguity - Are curious about AI and how technology reshapes work Granter is still early in its journey, and we are serious about creating an environment where things get built. People here tend to befriend each other and often stay engaged with the team beyond the strict boundaries of work. We regularly spend time together through team activities and startup ecosystem events. If that excites you, we'd love to hear from you. If it scares you, this may not be the right place, and that's okay. ## Location Requirement This role requires physical presence in Lisbon.
