Job description

Location: Maidstone (Hybrid — 2 days WFH)

Employment type: Full-time / Permanent

Salary: £28,000 – 33,000 (based on experience)

Hours: Monday–Friday (37.5 hours a week)

Reports to : Lead Front-End Engineer

Why apply?

You’ll be working on real products used by millions of people, not stuck fixing CSS on internal dashboards. You’ll gain hands‑on experience in production web code, component libraries, mobile app development, and cross‑team collaboration.

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.

Perks of the Job

• 20 days holiday + bank holidays, increasing by 1 day per year of service
• Extra day off on your birthday
• Hybrid and flexible working (2 days WFH)
• Macbook Pro
• Pension Scheme
• Employee Assistance Programme with 24/7 wellbeing support
• Cycle‑to‑work scheme
• Free parking and a dangerously well‑stocked snack & refreshment bar
• Casual, friendly office environment with regular team activities in an amazing woodland/garden setting.

How to Apply

Apply via the Jobs page on our website; you can upload your CV and cover letter there.

Interview Process

1. Initial Call (10 mins) – A quick, friendly chat with our Lead Front-End Engineer.
2. 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.

If you’re looking for a role where you can grow, learn, and contribute to real customer‑facing products rather than being another ticket‑churner, we’d love to hear from you.
