Javascript Developer (Back end focused)

Full Stack Developer - back end focused

Salford Quays (4 days onsite)

£55,000 - £70,000 + bonus

I’m working with a fast-growing online retail / eCommerce brand looking to hire a back end focused Full Stack Developer into its in-house technology team.

This role would suit a developer with a strong backend bias who enjoys working across systems, integrations and data, while still being happy to support broader full stack development where needed.

The business operates in a high-volume eCommerce environment, so this is less about building isolated features and more about developing the backend services, integrations and internal systems that keep a complex retail operation moving. Think eCommerce platforms, operational tooling, third-party integrations, data flows and automation across the wider business.

The role

You’ll be joining a growing tech team and will play a key role in building and maintaining the systems that sit behind a modern eCommerce operation.

Key areas of focus include:

• Designing, building and maintaining scalable backend services and integrations supporting eCommerce platforms and internal systems
• Developing APIs and services using technologies such as Node.js to support data flow between internal tools, third-party platforms and customer-facing applications
• Owning integrations from planning through to development, deployment and ongoing maintenance
• Contributing to backend architecture with a focus on reliability, scalability and performance
• Building and maintaining serverless functions / microservices and identifying opportunities for automation and process improvement
• Supporting data pipelines, operational reporting and analytics workflows across the wider platform estate
• Working across databases and data platforms, helping to optimise data models and query performance
• Collaborating closely with technology, eCommerce, content and design teams to deliver reliable systems and features across the business
• Supporting front-end / platform changes where required, particularly within an eCommerce environment

What they’re looking for

The ideal background will include:

• Around 3+ years’ experience in a backend or full stack engineering role
• Strong commercial experience with Node.js or similar backend technologies in production environments
• Experience designing and building APIs and integrating with third-party systems
• Exposure to serverless architectures such as AWS Lambda or similar
• Experience working with databases / data platforms such as MongoDB, PostgreSQL, BigQuery or similar
• Familiarity with CI/CD, Git and modern development workflows
• Experience building or contributing to system integrations, backend services and data pipelines
• A practical, hands-on approach and the ability to work in a fast-moving commercial environment

Nice to have

Any of the below would be beneficial, but they are not essential:

• Experience with Shopify integrations or Shopify / eCommerce platform work
• Exposure to React or other modern front-end frameworks
• Experience with internal tooling platforms such as Retool
• Knowledge of warehouse, courier, fulfilment or order management systems
• Previous experience in retail, eCommerce or other high-traffic digital environments

Package

• £55,000 - £70,000 depending on experience
• 5% - 10% bonus
• 25 days holiday plus bank holidays
• Additional day off for your birthday
• Flexible working around core hours
• Enhanced pension contribution
• Healthcare cash plan
• Enhanced maternity and sick pay
• Staff discount
• Free onsite gym
• Hybrid working with 4 days onsite

If you’re a backend-leaning full stack engineer who enjoys working on integrations, internal systems, data flows and the operational engine behind a growing eCommerce business, I’d be happy to talk you through the role.
