Senior Full-Stack Software Engineer
Join a dynamic AI start-up revolutionising grants and help shape the future of funding.
About Grantify
At Grantify, we’re transforming how businesses secure government funding. From our humble beginnings as a 2-person team, we’ve grown into a thriving 60+ strong organisation with operations across the UK and US empowering start-ups to access millions in non-dilutive funding through our AI-enabled platform.
Having already helped clients secure over $200M in funding, we’re now entering our next phase of product innovation, building scalable tools that make the funding process faster, smarter, and more intuitive.
The Role
We’re looking for Senior Full-Stack Engineers to join our growing Engineering & Product team.
You’ll play a key role in shaping the next generation of Grantify’s products, developing full-stack solutions. From designing beautiful, performant interfaces to building scalable APIs and cloud integrations, you’ll work end-to-end on projects that directly impact how founders access funding.
If you’re passionate about clean, well-structured code and love seeing your work go live fast in a lean, collaborative team - this is the place for you.
Why You’ll Love Working Here
🧠 Build from Scratch – Work on greenfield projects and new product features from the ground up, not endless refactors.
⚡ Impact & Autonomy – Join a small, nimble team where your ideas directly shape what ships.
🤝 Collaborative Culture – Work cross-functionally with Product teams that value experimentation and shared learning.
🌍 Startup Energy, Real Growth – Move fast, avoid bureaucracy, and make visible impact in a high-growth business.
🧩 End-to-End Ownership – Take responsibility for the full lifecycle, from concept to deployment and beyond.
💡 Innovation Friendly – While ML experience isn’t required, there’s room to explore how AI can enhance our platform if that excites you.
