Job description

Tewkesbury (UK) - Hybrid Remote (in-office on Tuesdays) - UK Applicants Only

Posted 6/9/2025

mmtm (pronounced momentum ) is a UK-based digital agency that designs and builds bespoke web apps for clients across industries. We’re a small (but growing), remote-first team that cares about clean design, smart strategy, and code that actually gets used.

As long-term partners to our clients, we play a critical role in their growth through the products we build and manage. Right now, we’re also growing our own in-house product suite - so it’s an exciting time to get on board.

The Role

We’re looking for a full-stack Ruby on Rails developer to join our friendly, fast-moving team. You’ll be working closely alongside our lead developers to deliver high-quality digital solutions for our clients and their customers. You'll be learning on the job and our aim will be for you to progress quickly in a wide range of technical areas. We want to provide you with well rounded full-stack knowledge that you can apply to great success.

You’ll be joining a close-knit squad of developers and PMs, helping shape and ship features from start to finish - working with Ruby on Rails and Stimulus , as well as some interaction with React , Typescript , NestJS , and much more.

We’re collaborative, not siloed - so even if you’re focused on one client, you’ll always be part of the wider mmtm team.

What We're Looking For

• Foundation in Ruby on Rails , with an eagerness to learn more.
• Solid grasp of HTML5, CSS3, and SASS .
• Some experience or interest in learning React , NestJS , NodeJS and/or TypeScript .
• UK-based and happy to join us in our Tewkesbury office on Tuesdays.
• A collaborative, positive mindset - someone who thrives in an agile team.
• Enthusiasm for clean code, learning new tools, and a focus on practical solutions.
• Friendly, upbeat attitude, and an ability to keep up with our terrible puns and GIFs.
• Previous agency experience or professional experience as a developer.
• Familiarity with Agile and Sprint methodologies.
• Understanding of Git version control and code reviewing practices.

What You'll Get

• £23k-£30k salary , based on experience, with regular reviews.
• Remote-first culture with hybrid working (just one in-office day per week).
• Shorter 35-hour week , generous holiday allowance (24 days + bank holidays), plus your birthday off as an extra free day
• Annual learning budget for courses, books, or conferences.
• Latest MacBook and any gear you need.
• Career development support: regular check-ins, annual reviews, and space to grow.

How We Hire

We keep things friendly, fast, and human:

• Apply: Send us your CV.
• Intro Chat: 30-minute video call with our founders.
• Tech Interview: A live coding session and technical conversation.
• Offer: If it's a fit on both sides, we'll make an offer right away.

We're open to either full-time employment or an initial 6-12 month contract - just let us know what works best for you.
