About the opportunity

We’re looking for a Lead Full Stack Developer to be the senior-most hands-on engineer in a delivery team. You’ll personally design and build the most complex, highest-risk features across the web and back-end services that power Core Group’s omnichannel platform, while raising the technical standard of the wider engineering team through strong design, code review and mentorship.

What you’ll be doing

• Design and build complex end-to-end features across Angular/React front ends, .NET/C# and Node.js services, and SQL/NoSQL data stores.
• Contribute production code regularly and set the technical standard by example.
• Build and maintain back-end APIs and services used by web and native mobile clients, with clean, well-versioned contracts.
• Translate solution architecture into detailed component, API and data designs that the team can implement.
• Lead code and peer reviews, champion automated testing, clean code, maintainability and secure engineering practices.
• Mentor engineers and help strengthen technical craft without formal line-management responsibility.
• Design and build integrations between e-commerce, trade-in and POS and core ERP/OMS/WMS/CRM platforms using Azure integration technologies.
• Support production issue resolution and technical readiness for peak trading and major product launches.

Technology stack

• Front end: Angular and React
• Back end: .NET / C# and Node.js
• Data: SQL Server, PostgreSQL and Cosmos DB
• Cloud: Microsoft Azure
• Integration: Azure Integration Stack with ERP / OMS / WMS / CRM platforms

What we’re looking for

• Degree in Computer Science or a closely related field, or equivalent practical experience.
• 8+ years in full-stack software development, including recent experience as a senior or lead engineer.
• Deep hands-on experience across Angular, React, .NET/C#, Node.js, SQL Server, PostgreSQL and/or Cosmos DB.
• Strong Azure and integration experience, including API design and versioning.
• Excellent technical design, code-quality, testing and secure-coding discipline.
• Strong problem-solving skills and the ability to mentor and influence other engineers.

Advantageous

• Retail, e-commerce, POS or omnichannel experience.
• Experience building on Azure and the Azure Integration Stack at scale.
• Experience delivering through high-demand events such as product launches and peak trading.

What will make you successful

You are still deeply hands-on, enjoy the most difficult technical work and naturally raise the quality of everyone around you.

How we work

We value customer focus, getting things done, teamwork, innovation, integrity, passion and embracing differences. We’re looking for people who bring those values into the way they solve problems, collaborate and deliver.

Please note: These roles may require occasional out-of-hours support during peak-trading and major product-launch windows, as well as occasional travel between offices or supported markets.

If this sounds like the kind of challenge you’re ready for, we’d love to hear from you.
