Section 01
What a Full Stack Developer Does
A full stack developer builds across the whole application, from the storefront customers interact with to the servers, APIs and databases that power it. In eCommerce that means shipping features end to end: a new checkout flow, a product feed, a headless build on a modern JavaScript stack, or an integration with a payment or logistics platform. Because they cover both ends, full stack developers give lean online teams the flexibility to move fast without waiting on separate specialists.
The role is commercial as well as technical: performance, uptime and release speed all affect revenue. These are the core areas across most full stack developer jobs London teams hire for.

FAQ
Frequently Asked Questions
01How much do full stack developer jobs London pay?
Full stack developer jobs London pay an average of around £65,000 to £72,000. Junior developers start at £32,000 to £45,000, mid-level developers earn £52,000 to £70,000, senior developers £75,000 to £100,000, and leads £95,000 to £125,000 and above. Modern JavaScript and headless specialists command a premium.
02Do full stack developers out-earn front end developers?
Often, yes. Because full stack developers cover both the front and back end, they tend to earn slightly above single-discipline front end developers at the same level. The gap is not huge, and a specialist front end or React developer with scarce skills can match or beat a generalist full stack salary. Versatility is what pushes full stack pay up as you get more senior.
03Which stack pays the most for full stack developers in London?
Modern JavaScript stacks pay best in eCommerce. Next.js and headless commerce skills top the range at £70,000 to £105,000 in London, followed by MERN or Node and React. .NET and Python suit enterprise and data-heavy builds, while PHP and Laravel remain common and well paid where Magento or bespoke platforms are involved.
04What skills do you need for full stack developer jobs?
Employers want strong JavaScript and a modern framework such as React or Next.js on the front end, a back end language such as Node, PHP, .NET or Python, and solid database skills across SQL and NoSQL. Add cloud, Git, CI/CD, testing and API design, plus a focus on performance and security. In eCommerce, commercial awareness and the ability to ship features end to end matter as much as the code itself.
05How do I get a full stack developer job in London?
Ship real projects front to back with public code and a live demo, go deep on a modern JavaScript stack with cloud and CI/CD experience, and be ready to talk architecture and commercial impact at interview. Apply for junior, mid or senior roles depending on experience, and work with a specialist recruiter, as versatile full stack talent is in short supply and many roles are filled through networks first.
06Are full stack developer jobs remote or hybrid?
Development is one of the most remote-friendly fields, and many full stack developer jobs are fully remote or hybrid, typically two to three days in the office. Plenty of London-based roles are open to strong candidates across the UK, though the capital still offers the deepest market and the highest pay.
