About Format
Format is rebuilding how digital design assets get made.
Every existing tool makes you work on a bitmapped canvas, dragging and dropping shapes and text.
Format doesn't. Every Format is a webpage: developers build a template using CSS and JSX, then configure a form builder that exposes specific fields - text, images, JSON data, even live data feeds - to end users. The result is a tool where anyone, regardless of design skill, can produce on-brand, error-free assets in seconds.
We’ve launched in market, with sports, media, agencies and events clients (including Wisden, Major League Rugby, Sofar, Platform Media) and expanding more, pulling in real-time data from providers like CricViz and Oval Insights and content libraries from Getty, Air and so on to auto-populate graphics that get distributed on a schedule via Slack and email.
Role Overview
As a Developer joining Format, you'd be working at the intersection of web development and design tooling - building the underlying rendering engine that lets non-technical users manipulate live, code-driven templates without ever touching code themselves.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
This role sits at the intersection of front-end engineering and visual design. The day-to-day work is building images with JSX inside our internal tooling - writing components and using data (loops, conditionals, arrays, objects) to control what those components render.
Strong JavaScript fundamentals matter more here than deep design experience, though an eye for visual design remains a genuine advantage.
It's a small, fast-moving team, so you'll have real ownership over how the product evolves, not just a slice of it.
Key Responsibilities
- Build Format templates using our internal JSX-based tooling
- Translate client designs into high-quality, responsive JSX/CSS Format templates which include a wide range of inputs
- Collaborate with designers, marketing and the wider product team to build intuitive, engaging experiences within Format
- Ensure the technical feasibility of UI/UX designs
Secondary Responsibilities
- Contribute to the feature roadmap and ongoing development of the Format product
- Test, troubleshoot and debug issues related to design templates and the Format platform
- Add to the team’s culture as we look to scale and grow
