About Executive Channel Network Executive Channel Network (ECN) is a Digital Out-of-Home (DOOH) advertising company operating across the UK, France and Germany. Our premium screen network reaches business audiences in the workplace environments they spend most of their day in. We are a lean, commercially focused organisation, and our technology stack directly underpins the commercial, operational and creative engine of the business. The Role We are hiring a Senior Full-Stack Developer to be the technical backbone of our London operation. You will work directly with the CTO on a defined set of priority projects, but day-to-day you will run your own schedule, make your own technical decisions, and drive projects to completion largely autonomously. This is a hands-on, high-ownership role. It will suit a commercially minded engineer who is equally comfortable refactoring legacy PHP, upgrading Linux servers, cutting responsive HTML5 and CSS from a designer's mockup, and scripting automations that remove friction for Finance, Marketing and Operations. You will also be encouraged and expected to use AI coding tools such as Claude Code to meaningfully accelerate your output - we treat AI-assisted development as a core productivity lever, not a novelty. Key Projects You Will Own 1. SuiteCRM Platform Ownership and Major Version Upgrade Our SuiteCRM instance is central to ECN's sales and operational workflow. You will own it end-to-end: • Ongoing development, customisation and bug fixing of the current SuiteCRM deployment., • Planning and executing an upgrade to the latest SuiteCRM version, including the underlying server infrastructure., • Rewriting and modernising ECN's custom SuiteCRM plugins and bespoke code so they are compatible with the target version., • Establishing a sensible approach to environments, deployment, backups and future upgrade paths so we are never this far behind again. 2. Dynamic HTML5 / CSS Creative Template Stack Our screen network runs off a library of dynamic creative templates. On this stream you will work directly with ECN's Australia-based Content Director, who owns the creative direction and template roadmap, and with our in-house designers on individual builds: • Upgrading our existing dynamic HTML5 and CSS templates to a modern, maintainable baseline, against priorities set by the Content Director., • Building new templates from designer specifications where commercial or creative needs demand it., • Ensuring templates render reliably across the playback environments used on our network., • Comfortable collaborating across time zones — the Content Director is based in Australia, so expect asynchronous working with occasional scheduled calls. 3. Business Automation across Finance, Marketing and Operations ECN's internal teams have real, repeatable processes that are currently manual. You will work with Finance, Marketing and Operations to identify, design and build automations that remove this overhead — from integrations between existing SaaS tools through to bespoke internal utilities. You will be expected to scope, prioritise and ship these in conversation with the CTO and the relevant business owner. How You Will Work • Autonomy first. You will receive direction and feedback from the CTO, but you will be trusted to plan, estimate and deliver under your own steam. If you need a hand-holding environment, this is not the role., • Small, focused team. You will work alongside our Global IT and UK Tech lead in London and a programmatic / content specialist in ANZ. The CTO is actively involved but not a bottleneck., • Pragmatic engineering. We value shipping, maintainability and commercial awareness over architectural purity. We want you to leave the codebase and the infrastructure in better shape than you found them., • AI-assisted development. You will use Claude Code or equivalent tooling as a core part of your workflow. We expect you to have opinions on where it helps, where it doesn't, and how to use it safely on production code. What You Bring Essential • 5+ years of professional software development experience, with meaningful time spent as the senior or lead engineer on a product or platform., • Strong PHP skills and demonstrable experience working inside, customising or upgrading a substantial PHP application (SuiteCRM, SugarCRM, Magento, WordPress at scale, or similar legacy-but-live platforms)., • Comfortable administering Linux servers: MySQL/MariaDB, Apache or Nginx, PHP-FPM, deployment, backups and basic security hygiene., • Fluent in modern HTML5, CSS and JavaScript, with the ability to translate designer output into production-quality, responsive markup., • Track record of building integrations and automations against third-party APIs (finance systems, marketing platforms, internal tooling)., • Active, deliberate use of AI coding assistants such as Claude Code, and the judgement to know when to lean on them and when not to., • Excellent written and spoken English, and the communication skills to work directly with non-technical stakeholders in Finance, Marketing and Operations., • Right to work in the UK. Nice to Have • Direct SuiteCRM or SugarCRM experience, including custom module or logic hook development., • Experience running a major version upgrade of a business-critical legacy system., • Exposure to the Digital Out-of-Home, AdTech or MarTech space., • Familiarity with modern front-end frameworks (React, Next.js) for internal tooling work., • Cloud infrastructure experience (AWS or equivalent), including CI/CD. What Success Looks Like • By month 3: You own the SuiteCRM environment, have cleared the critical bug backlog, and have produced a credible upgrade plan with infrastructure and plugin migration scoped., • By month 6: SuiteCRM is upgraded or well into execution, the dynamic template stack has been modernised, and at least one material business automation is live and in use., • By month 12: You are the trusted go-to engineer for the London business, operating independently against a rolling priority list agreed with the CTO, and measurably improving velocity across the technology function. Why Join ECN • Real ownership: a defined remit with genuine scope, not a ticket queue., • Direct line to the CTO and exposure to commercial decision-making., • A tech function that is being rebuilt — you will have unusual influence over how we work, what we use and what we build., • Competitive London salary with room to grow as the function scales. How to Apply Send a CV and a short note telling us about the most complex legacy system you have modernised, and how you currently use AI tooling in your day-to-day work. We read every application. Executive Channel Network is an equal opportunities employer. We welcome applications from all qualified candidates regardless of background.
