Full Stack Developer in London

Blackbridge is looking for a technically versatile full stack web developer who can move confidently between front-end build, back-end development, and infrastructure. You’ll help deliver fast, secure, accessible websites and digital experiences, working closely with our design and digital teams to turn ideas into polished, reliable outputs.

Location: Spitalfields, London (3 days in the office, 2 from home)

Reports to: Director, Digital Operations

Salary: TBC

A bit about Blackbridge: As one of the largest independent people communications agencies in the UK, Blackbridge Communications helps household name brands to attract and engage talent. Located in Spitalfields, London, we do that by developing and delivering creative campaigns and strategies across all channels, from digital and social through to outdoor and experiential. One of the reasons why we’re so dedicated to delivering exceptional work for our broad range of clients, including organisations such as Aviva, Amazon, Microsoft and Vodafone, is the fact that we’re an employee-owned business. It means we all have a real stake in our success. Join our 35-strong team of Creatives, Strategists, Client Partners and Delivery specialists, and you’ll have that stake too.

About the role: This role balances four core areas:

• Web development: Building performant, interactive websites using HTML, CSS, JavaScript/TypeScript, and modern frameworks, with strong attention to accessibility and technical SEO, coupled with PHP and Node.js back-end services.
• UI/UX integration: Bringing creative concepts to life in the browser, collaborating closely with design tools and design-thinking to create intuitive experiences across devices.
• Communication: Explaining technical concepts clearly to both technical and non-technical stakeholders, and working collaboratively across the team.
• Infrastructure & server management: Provisioning and maintaining hosting environments, applying security hardening, and keeping services reliable.

Practically, you’ll be hands-on across new builds and ongoing improvements to existing solutions, owning pieces of work end-to-end: design interpretation, build, integration, deployment, and maintenance.

Key responsibilities:

• Web development: Build modern, accessible front-ends using HTML, CSS, JS/TS.
• Create interactivity and animations, optimise performance, and apply accessibility best practice.
• Work with frameworks (e.g. React/Preact/Solid/Vue) and modern build tooling (e.g. Vite/webpack/Rollup).
• Develop back-end functionality in PHP and Node.js.
• Build and maintain CMS-driven sites (WordPress, Payload, etc.), including theme/plugin development for WordPress.
• Design and integrate APIs (PHP/Node.js) and connect third-party services.
• Use git/GitHub effectively and contribute to CI/CD (e.g. GitHub Actions).
• Keep security front of mind (OWASP awareness, browser security principles like CSP/HSTS and XSS prevention).
• Show curiosity about AI and how it can support site build and functionality.
• Experience in managing hosting/infrastructure.

UI/UX and design integration:

• Translate design concepts into engaging, user-centred experiences across mobile and desktop.
• Contribute to prototyping, wireframing, and motion/interaction design.
• Work confidently with Figma and Adobe Creative Suite.
• Have a curiosity and drive to identify new and emerging trends and functionality to elevate the candidate experience as part of the build.

Requirements:

We’re looking for someone who enjoys working across the full stack and feels comfortable moving between different kinds of challenges in a typical week. You’ll be a clear, confident communicator who can work well with fellow specialists, but who can also explain technical decisions in a way that makes sense to people who don’t have a technical background. You’ll probably thrive in this role if you like practical problem-solving and you’ve built up experience across web development and infrastructure. You’ll be happy writing solid code, getting prototypes together when needed, and troubleshooting issues with a calm, hands-on approach. Just as importantly, you’ll care about doing things properly, treating performance, security, and accessibility as part of the job, not add-ons, and you’ll enjoy working closely with designers, developers, and stakeholders to deliver thoughtful, high-quality digital experiences.

Benefits:

Our benefits are competitive and intended to help make your life a little easier:

• Unlike most agencies, we're employee-owned - which is exactly as it sounds. After 12 months, you'll become a Partner of Blackbridge and receive your fair share of our profits.
• Being employee-owned, we have a colleague appointed representative (Partner Councillor) who gives us the chance to voice our opinions on various elements of the business in an open and productive manner.
• A work-life balance is important to who we are, that's why we have a hybrid work policy, with 3 days in the office and 2 days working from home.
• We have regular socials and events to give us the chance to make genuine friendships and connections outside of the workday. Activities we've had in the past include quiz nights, karaoke, drinks at various Central London pubs/bars and The Cube.
• 25 days' holiday with 1.5 days gifted over Christmas.
• Our Employee Assistance Programme is available to you 24/7, which offers mental health support through courses and counselling sessions.
• Health Cash Plan – claim back costs for everyday healthcare (dental, optical, prescriptions, physiotherapy, etc.), plus access to a wide range of discounts.
• Enhanced parental pay and leave, so you can settle your family in, enjoy the early days and maintain your sense of financial security.
• You’ll have access to our company pension scheme, helping you save towards your long-term financial wellbeing.
