We're working with a premium Shopify agency that specialises in the projects most agencies wouldn't.
We're looking for a Lead/Senior Full Stack Software Engineer who wants to solve genuinely complex engineering problems, rather than simply build another Shopify store.
You'll work on projects involving complex integrations, custom systems and highly personalised customer journeys, helping architect solutions that push Shopify well beyond its standard capabilities.
This is an engineering role in the truest sense.
You'll be involved in:
- Architecting and building scalable, maintainable solutions
- Turning complex requirements into clear technical approaches
- Making key technical and architectural decisions
- Helping shape engineering standards and development processes
- Working closely with PM, Design and Data teams
- Using AI effectively within your development workflow and helping identify where emerging technologies can improve how we build and deliver
What we're looking for:
- Strong commercial Shopify experience
- 5+ years of JavaScript
- Strong Node.js and Vanilla JavaScript (ES6+)
- Good working knowledge of AI tools and how to use them effectively within software engineering
- Experience with serverless / cloud functions
- A genuine engineering mindset, with experience owning technical solutions rather than simply picking up tickets
- Strong communication skills and the ability to explain technical decisions clearly
Experience with AWS / GCP / Azure or enterprise CMS platforms would be a bonus.
The team is based in Leeds, with a flexible working approach. There's no fixed requirement to be in the office, but ideally you'll be able to get into Leeds around once a week/once every two weeks.
If you're a Senior Shopify Developer who has moved towards architecture, engineering and technical ownership, this could be an interesting one.
