Systems Developer

Systems Developer – Backend Integration (Golang | Magento | Enterprise Systems)

Liverpool | Hybrid (3 days onsite to start)

We’re hiring a standalone Systems Developer to take ownership of a complex backend integration landscape within a high-volume e-commerce environment.

This role sits at a pivotal moment: the systems need modernising, simplifying, and rethinking. You’ll be given the autonomy to challenge legacy processes, redesign architecture, and build scalable, cloud-native integrations that underpin the business.

This is a hands-on role with strategic influence, working closely with senior stakeholders and with a clear opportunity to grow a team around you as the function evolves.

This is for someone who wants autonomy, influence, and ownership.

The mission:

You will re-architect and modernise how the business connects its systems, from Magento to WMS, ERP and Finance, building scalable, cloud-native integration services that power high-volume trading.

You’ll:

• Own the backend integration landscape end-to-end
• Redesign legacy processes and replace them with clean, modern architecture
• Build Golang-based microservices and middleware to connect Magento with WMS, ERP and finance systems
• Create real-time order, stock and warehouse sync services
• Introduce modern engineering standards, tooling and best practice
• Act as the technical bridge between engineering, operations, and senior stakeholders
• Shape the future roadmap, with scope to build and lead a team as the function grows

What you’ll bring:

Core

• 5+ years commercial backend development
• Strong Golang experience (or production-level exposure + desire to specialise)
• Experience integrating Magento with enterprise systems
• Strong SQL and data modelling skills
• Experience building scalable, event-driven or middleware platforms

Architecture & Engineering

• Clean / Hexagonal Architecture
• Domain-Driven Design
• Event-driven & message-based systems
• Docker & containerised services
• AWS (EC2, Lambda, SQS, RDS) or similar
• Monitoring & observability tools

The personality fit:

We’re looking for someone who is:

• Confident and proactive
• Personable and credible with stakeholders
• Energised by variety and ownership
• Excited by complexity, scale, and impact

You’ll work daily with engineers, warehouse teams, product leaders and the SLT, so communication matters as much as code.

Package:

• 10% bonus
• 25 days holiday + bank holidays
• 🎂 Birthday off
• Hybrid working (3 days onsite to start)
• Career-defining ownership & future leadership scope
• 45-minute technical discussion with the hiring manager
