Principal / Senior Ruby Engineer | Luxury Commerce Platform | Well-funded start-up | Up to £150k | Flexible working options
I’m currently partnered with a well-funded business building a next-generation commerce platform within the luxury retail space.
While early from an engineering perspective, the group already operates at significant scale and has recently made a number of high-profile acquisitions, bringing multiple established brands into a single ecosystem.
They are now rebuilding their core platform from the ground up to support this, creating a rare opportunity to shape architecture at an early stage, within a business that already has strong commercial traction.
The Opportunity
This is a genuinely high-bar Ruby environment, designed for engineers who want to use the language to its full potential.
You’ll be working within a small, highly experienced team, focused on solving complex systems problems properly, with low process, high trust, and real ownership.
Responsibilities
• Design and architect complex e-commerce systems (inventory, pricing, concurrency, payments)
• Build a scalable platform spanning multiple brands and marketplaces
• Develop high-performance backend systems using Ruby beyond Rails
• Work extensively with distributed systems and third-party integrations
• Contribute to core architectural decisions in a greenfield environment
Core Requirements
• 8+ years backend engineering experience
• Strong Ruby expertise (metaprogramming, DSLs, object model)
• Experience operating at Senior / Principal level
• Proven track record designing complex e-commerce or marketplace systems
• Strong system design and distributed systems experience
• Experience building APIs (REST and/or GraphQL)
• PostgreSQL and performance optimisation experience
