We are looking for a Senior Full-Stack Developer with a strong frontend focus to take ownership of the development of our new platform, GrantBite. This is an expert-level individual contributor position – you will be the go-to technical expert for our frontend and the connecting layer to our backend systems.

You will currently work as a hands-on expert without direct reports. However, as GrantBite grows, there is a clear path toward taking on leadership responsibility as the team expands – making this an ideal position for someone who wants to build something from the ground up and grow with it.

You will shape the frontend vision and execution of a modern, dynamic, high-performance platform that transforms how organizations discover and manage non-dilutive funding.

GrantBite is building the infrastructure that connects funding capital with the projects it is meant to enable – turning fragmented funding programs into a structured, repeatable financial strategy.

We are an international team of top performers from multiple industries – combining funding expertise, product thinking, software engineering, and design & motion experience. Together, we are building a system that moves funding from discovery to execution in one structured workflow. Our ambition is to create a world where capital flows efficiently to innovation – without unnecessary complexity or friction.

You will define how GrantBite feels. We want a frontend experience on the level of modern AI-native platforms such as n8n, Wispr Flow, or Airops. This means building:

•      High-performance interfaces with fast load times and seamless responsiveness

•      Motion-driven UX with fluid transitions, micro-interactions, and visual storytelling

•      Visual depth through light, shadow, and spatial layering

•      Robust payment and subscription systems powered by Stripe

You will work closely with our UI/UX designer who handles all design work – your job is to know which technologies and animation frameworks are currently state-of-the-art and to translate those designs into production-ready, performant code.

•      Own the frontend architecture of GrantBite and take responsibility for scalable, performance-first UI systems

•      Implement dynamic, interactive user interfaces and translate motion/animation concepts into real UX

•      Work hand-in-hand with our designer to bring animation, lighting, and depth to life in the browser

•      Ensure fast loading times and seamless responsiveness using modern rendering strategies (SSR, ISR, edge rendering)

You understand the current landscape of motion and animation libraries and can make informed decisions about which tools to use for which purpose. We expect hands-on experience with several of the following:

•      Motion (formerly Framer Motion): The most widely used React animation library – declarative API, gesture handlers, layout animations, AnimatePresence for mount/unmount transitions

•      GSAP (GreenSock): Timeline-driven, high-fidelity animation control – ideal for complex, sequenced animations and scroll-driven effects

•      React Spring: Physics-based animation for fluid, natural-feeling motion – great for drag gestures, elastic transitions, and interactive UI

•      Three.js / React Three Fiber: 3D rendering and WebGL-powered visual effects where needed for spatial depth and immersive elements

•      Lottie: For integrating designer-created After Effects animations as lightweight, scalable JSON assets

•      Animated UI Libraries: Familiarity with modern component libraries like Aceternity UI, Magic UI, or shadcn/ui that combine Tailwind CSS with Framer Motion for production-ready animated components

You don’t need to master every single library – but you need to understand the ecosystem, know when to use what, and be able to implement motion-rich interfaces that feel polished and performant.

While your primary focus is frontend, you are comfortable navigating the backend when needed:

•      Connect to and consume REST APIs and GraphQL endpoints

•      Understand database concepts and be able to write basic queries

•      Implement and debug API routes in Next.js (App Router, Server Actions)

•      Handle authentication flows (e.g., NextAuth / Auth.js)

•      Troubleshoot and resolve backend issues when they arise – you don’t need to be a backend specialist, but you shouldn’t be blocked by backend tasks

•      Next.js (App Router) with React + TypeScript

•      Tailwind CSS / modern styling systems

•      Motion (Framer Motion), GSAP, React Spring for animations

•      Three.js / React Three Fiber for 3D/WebGL where applicable

•      Stripe (Subscriptions, Credits, Webhooks, Customer Portal)

•      Server Components, Server Actions, and Edge Rendering

We are a Germany-based company operating in Central European Time (CET). We offer significant flexibility in how you structure your workday:

•      Core hours: At least 4 hours of overlap between 9:00 AM – 6:00 PM CET (for meetings, collaboration, and real-time communication)

•      Flexible hours: The remaining 4 hours can be scheduled at your discretion

•      Full-time & dedicated: This is a full-time position (approx. 40h/week). We expect you to be fully dedicated to GrantBite with no other freelance or employment engagements

This structure allows us to collaborate effectively while respecting your autonomy over your schedule.

We are early stage – which means high impact, high ownership, and high growth potential. You won’t just build features. You will build the experience layer of a platform designed to make funding strategic, structured, and scalable.

As the founding developer on the frontend, you will have a direct path to a leadership role as the team grows.
