Full-Stack Engineer

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 a Full-Stack Engineer. A versatile builder who enjoys taking a problem and turning it into a working product, end-to-end.

What This Role Involves

• Be part of the tech team, working closely with engineering, product, and leadership

• You will start by learning the full system, then move into a cross-functional squad with full ownership of a specific domain

• 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

• We aim to be at the frontier of vertical AI agents, and you are expected to help push that forward.

• 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

This role is for someone versatile, ambitious, and willing to learn fast. Someone who enjoys figuring things out, taking ownership, and building across different parts of the system. We are looking for a builder. We care more about evidence than years, but below is the minimum baseline we believe you need to be effective:

Experience

• 2+ years of software development experience

• Hands-on experience with Python

• Experience with at least one JavaScript framework

  
  

Additional Plus

• Experience working in a startup environment

• Exposure to AI product interfaces or AI-assisted workflows

• Degree in Computer Science, Software Engineering, or a related field is a plus

• Experience using AI-assisted development tools effectively (e.g. GitHub Copilot, Claude, Cursor) is a plus

  
  

Core Skills

• Strong Python skills

• Frontend fundamentals, including HTML, CSS, and JavaScript

• Familiarity with APIs, application structure, and backend fundamentals

• Experience with Tailwind CSS

• Good engineering hygiene, including Git and basic testing practices

• Nice to have: Django, LangChain, Vue.js, Celery, Docker, Azure

  
  

Communication

• Clear and direct communicator

• Able to explain technical decisions and tradeoffs

• Fluent in English and Portuguese

  
  

Mindset

• Strong ownership and ability to move problems forward without waiting for perfect specs

• 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.
