Remote friendly (Tewkesbury, England, United Kingdom)
United Kingdom
Full-Stack Developer
Tewkesbury (UK) – Hybrid Remote (Tuesdays in-office) – UK Applicants Only
mmtm (pronounced momentum) is a UK-based digital agency designing and building custom web apps for a range of industries. We’re a small (but growing) remote-first team that cares about clean design, thoughtful strategy, and code that people actually use.
We work as long-term partners to our clients, playing 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 a great time to get on board.
The Role
We’re looking for a Ruby on Rails developer with full-stack experience to join our friendly, fast-moving team. You’ll be supporting one of our key client projects - an industry-leading fibre telecoms platform - as well as occasionally contributing to other projects across our client base.
You’ll be joining a close-knit squad of developers and PMs, helping shape and ship features from start to finish - working heavily with React and TypeScript, as well as some interaction with NodeJS and NestJS too.
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
* A minimum of 1–2 years of professional experience as a developer.
* Strong foundation in Ruby on Rails, building production-ready features.
* Comfortable across the stack, with working knowledge of React and TypeScript.
* Some experience (or interest in learning) NestJS or other NodeJS frameworks.
* Good grasp of HTML5, CSS3, and SASS.
* UK-based and happy to join us in our Tewkesbury office on Tuesdays.
* Collaborative, positive mindset – someone who thrives in an agile team.
* Passion for clean code, curiosity about 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.
What You’ll Get
* £30k–£40k salary depending on experience, with regular reviews.
* Remote-first culture with hybrid working (just one in-office day a week).
* Shorter 35-hour work week plus 24 days’ holiday + bank holidays + your birthday off
* Annual learning budget for books, courses 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 the process simple, supportive, and human:
* Apply – Send us your CV.
* Intro Chat – 30-minute video call with our founders.
* Tech Interview – 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 both full-time employment or an initial 6–12 month contract – just let us know what suits you best.
