You’ll have an important part to play delivering high quality features and seamless integrations across our enterprise web platforms.

Here at Unipart we don’t just have a way of working, we have The Unipart Way. It allows everyone in our team to pursue their own personal and professional goals to a world class level, through Unipart's ‘From Gate to Great’ training and development program.

As a Full Stack Developer, you will own the day-to-day maintenance, uphold strict security, performance, and reliability standards, and actively develop platforms such as Intranets and inward/outward-facing websites across varying CMS frameworks (e.g., WordPress, headless, custom), integrations, and supporting services.

As part of your key responsibilities you’ll:

• Design, build, and deploy front- and back-end features (e.g., PHP/Node/JS, SQL), including implementing and maintaining system integrations (e.g., ERP/CRM, SSO)
• Take primary ownership of all business-as-usual (BAU) maintenance, small enhancements, and defect fixes across intranet and public-facing websites, adhering to agreed SLAs
• Maintain custom extensions, modules, and themes across multiple CMS stacks, following professional development practices like Git-based workflows and semantic versioning
• Uphold strict security and compliance standards by running regular checks, promptly patching vulnerabilities, and enforcing least-privilege access
• Focus on performance by meeting Core Web Vitals targets, optimising code, and monitoring uptime and error budgets
• Contribute to a defined quality and release process, including using CI checks, maintaining technical documentation, and following defined rollback plans
• Work with the Development Manager on the product roadmap, prioritisation, and acceptance criteria, providing clear estimates for delivery
• Decide implementation details and minor refactors; escalating scope shifts, architectural changes, and timeline risks
• Measure success by SLA adherence, release quality (defect escape rate), security posture, delivery predictability, and tech-debt reduction
• Engage in weekly check-ins, maintain a rolling two-week delivery plan, produce a monthly report on releases/incidents, and conduct quarterly reviews

We’d love you to have the following skills and experience, but please apply if you think you’d be able to perform well in this role!

• Proven proficiency in designing, building, and deploying features using front- and back-end technologies (PHP/Node/JS, SQL), with a strong foundation in Web Development and Application Development
• Expertise in maintaining custom extensions, modules, and themes across multiple CMS stacks and ensuring compatibility
• Ability to take primary ownership of all BAU updates, enhancements, and defect fixes, meeting agreed-upon service level agreements (SLAs)
• Strong focus on security, including vulnerability patching, monitoring, and enforcing least-privilege access across platforms
• Experience in optimising code and infrastructure to meet performance targets (e.g., Core Web Vitals) and monitoring uptime/error budgets
• Strict adherence to professional practices (Git, peer review) and proven ability to contribute to a defined quality and release process (e.g., CI checks, rollback plans)
