About Gendo
Gendo is a revolutionary, browser-based AI platform designed to empower architects and designers to generate accurate, high-quality visual representations of their designs in seconds, not days - a huge improvement on existing workflows.
Within 18 months of founding we built an alpha product, beta product and, in summer of this year, launched our early-access product publicly. Today this product has thousands of users across many organisations, generating tens of thousands of images.
We pride ourselves on being a lean, focussed and efficient team formed of highly talented individuals. This, and our product driven mantra, led to us securing both substantial pre-seed-stage and seed-stage funding from renowned investors within the space, enabling us to expand our team and deliver on our ambitious vision.
What we value
At Gendo, design is at the core of our mission— both in the design of our products and also through its power to elevate creative expression, pushing the boundaries of architectural possibilities.
Driven by the power of collaboration, we have refined our technology in partnership with renowned firms such as Zaha Hadid Architects, Benoy, KPF, and David Chipperfield Architects, and of course within the Gendo team itself.
We take an exploratory approach to work, continuously innovating and seeking new ways to enhance the design process for our users.
Our ambition is big, we’re building a passionate, dedicated, world class team to transform the future of architecture and design, making cutting-edge tools accessible and enabling users to bring their boldest ideas to life with speed and precision.
Role Overview
As our Senior Frontend Engineer, you will take ownership of the frontend development for a highly interactive, sophisticated web application built in React (Next.js). Unlike many standard SaaS applications, this project is complex, involving real-time state management, 2D and 3D rendering, and advanced UI/UX features that are integral to our AI rendering product. The experience we’re building is akin to platforms like Miro or Figma, with a rich canvas-based UI powered by WebGL and real-time collaboration supported through WebSockets.
Given our small team, we value frontend developers with a strong eye for design and a knack for product thinking. The ideal candidate can comfortably fill in gaps when wireframes or detailed designs aren’t available, using our design system to maintain a cohesive visual language. If you’re excited about tackling frontend challenges and creating an intuitive, high-performance experience, we’d love to hear from you.
Key Responsibilities
-
Leading the development and architecture of a highly interactive React (Next.js) application, working closely with product and backend teams.
-
Managing complex application state and ensuring smooth UX in a real-time, collaborative environment using WebSockets for live updates and async generation results.
-
Implementing 2D and 3D elements within a canvas-based UI using three.js (react-three-fiber), supporting features like image resizing and future 3D model manipulation.
-
Optimising the frontend for performance and scalability, ensuring a seamless, responsive experience for users.
-
Applying product design sensibility to fill in design gaps when needed, leveraging our design system to ensure visual and functional consistency.
-
Collaborating closely with product and design colleagues to bring complex interactions to life and ensure consistency in visual and functional elements.
-
Championing best practices in frontend development, reviewing code, and mentoring junior developers.
Requirements
-
Extensive experience in building and deploying complex, production-level React applications.
-
Strong proficiency in Next.js, React state management (e.g., Redux, Zustand), and component-based architecture.
-
Experience with real-time data handling, ideally using WebSockets or similar technologies.
-
Understanding of three.js (or WebGL in general), or a strong interest in learning and applying these technologies.
-
Experience with full-stack development, particularly API design and development.
-
Solid understanding of frontend performance optimisation techniques and best practices.
-
Experience in designing and developing software products with l10n/i18n requirements.
It would be a bonus for you to have:
-
Product design experience or a strong eye for user-centric design.
-
Previous advanced experience with three.js or similar WebGL libraries.
-
(Extra bonus!) Experience or familiarity with CAD or 3D modelling software (e.g. Blender, 3DS Max) or computer graphics in general.
