About Us
Submission Technology was first established in 2002, when we launched the UK’s first-ever cashback website,
cashback.co.uk
. Since then, we’ve evolved into a modern performance marketing company, building member-focused platforms including
Custard
and its companion
Gift Card App
, as well as several other internal products and tools.
About the Role
As a
Junior Front-End Developer
, your primary responsibility will be to take design files and turn them into high-quality, responsive front-end code.
You’ll work closely with our
Lead Front-End Engineer
and senior developers, taking on smaller tasks, UI/UX improvements, and incremental feature work. This is a great role for someone who wants to grow into a mid-level front-end engineer and a great opportunity to get into the affiliate marketing industry outside of London.
The Day-To-Day
From the beginning:
Build responsive web pages using
HTML, CSS, and JavaScript.
Convert Figma design files
into clean and maintainable front-end code.
Pick up development tickets to iterate on and improve existing user interfaces.
Collaborate with developers to grow your technical knowledge and problem-solving skills.
Participate in code reviews, ensuring adherence to best practices and coding standards.
What progression looks like:
Contributing to our mobile app (
React Native / Expo
)
Working with backend developers and learning how
Python
drives data to the front end
Getting involved in the design process and having meaningful input
Opportunity to learn more advanced topics (API interactions, component libraries, version control, security, and much more)
Skill Set
Required:
Solid understanding of
HTML, CSS \& JavaScript
Ability to accurately replicate designs into responsive web interfaces
Strong communication and teamwork skills
Curious mindset with a passion for staying up-to-date with the latest industry trends and technologies.
Good time management and ability to work within a structured ticketing workflow
Nice to have (but not essential):
Experience interacting with
APIs
Understanding of core UI/UX principles
Exposure to modern frameworks (React or React Native)
Version control experience (Git
)
Familiarity with cloud platforms such as
AWS
Company Tech Stack
While you may not be directly involved with all these technologies, you may be interested in what else we make use of:
HTML, CSS, Sass, React, React Native / Expo, JavaScript, Python (Flask), PostgresSQL, AWS, Linux
What We’re Looking For
Someone who is eager to learn, motivated by solving problems, enjoys working as part of a collaborative team and takes ownership of their work, and isn’t afraid to ask questions.
If you’re passionate about front-end development and want to grow your skills while working on real products that millions of users engage with daily, this is the place for you.

Interview Process

A quick, friendly chat with our Lead Front-End Engineer.
Technical Interview + Mini Coding Exercise (30–60 mins) -
A relaxed conversation with our developers where we look at how you think, not whether you memorised syntax.
