We are looking for an experienced Senior Web Developer based in our London studio to support our development practice across the company.
Alchemy Digital is an award-winning digital agency based in Borough Market, London. We partner with an enviable portfolio of national and international clients to deliver exceptionally crafted digital experiences.
We are seeking an experienced Senior Web Developer to join our London studio and play a key role in shaping our development practice across the company.
You’ll work across our entire client portfolio, building websites, mobile apps, web applications, and innovative digital products for some of the most recognised organisations. This is a leadership role: you’ll take ownership of projects, mentor junior developers, and help drive technical excellence in everything we deliver.
While we’re looking for a senior developer, we value ambition and potential—if you’re an experienced intermediate ready to step up, we’d love to hear from you.
What we’re looking for
6+ years’ commercial experience, ideally within a digital agency environment.
Currently operating at a senior level, or ready to make the leap.
Proven ability to architect robust, scalable digital solutions.
Experience with headless React builds and frameworks such as Next.js (essential for modern, API-driven projects).
Strong CMS experience, including WordPress, and ability to develop eCommerce platforms using Shopify, Magento, WooCommerce.
Advanced PHP skills, including building custom WordPress themes from scratch; experience with ACF (Advanced Custom Fields) preferred.
Proficiency in modern web standards: HTML5, SASS, JavaScript (ES6+), and jQuery.
Familiarity with cloud hosting (e.g., WPEngine, AWS) and deployment processes.
Knowledge of build tools (Grunt) and version control (Git).
Comfortable managing DNS updates and running deployments.
Ability to work autonomously or collaboratively, including direct client interaction.
Experience scoping and quoting development work, with confidence discussing costs.
Appreciation for design and UX/UI principles; ability to contribute to polished user experiences.
QA and browser testing expertise, with meticulous attention to detail.
Enjoys mentoring junior team members and leading projects with clear communication and accurate planning.
Strong interpersonal skills and a genuine passion for digital innovation.
This role is London-based, and applicants must be located in London or within reasonable commuting distance to attend client meetings, team socials, and occasional in-office days.
Nice to have
Experience with API integrations and modern workflows.
Familiarity with performance optimisation and accessibility best practices.
Exposure to tools like Framer & Webflow is a plus, helping bridge the gap between design and development, enabling faster iteration on front-end experiences, and supporting more advanced use cases such as API integrations and custom code components.
What we offer
Opportunity to work with a talented, passionate team.
A diverse and exciting range of projects.
Monthly Socials.
A collaborative, creative studio environment (and a good sense of humour is essential).
Ongoing training and career development.
To apply please supply an up-to-date CV, your portfolio and a short message telling us why you think you'd be a good fit. Bonus points if you can start tomorrow.
