Senior Full Stack Engineer

Senior Full Stack Engineer (Frontend Focus)

Location: London (Hybrid) 1 day a week

Salary: up to £90,000

Evantis Technology is working with a fast-growing digital marketplace platform operating in the creative/consumer space, helping them hire a Senior Full Stack Engineer with a strong frontend focus.

The business is building technology that supports the full lifecycle of a marketplace platform — from partner onboarding and product creation through to customer purchasing experiences and operational tooling. Their engineering team works closely with product, growth and commercial teams to build scalable systems that support both the customer-facing platform and internal tools.

This role will play an important part in improving and evolving the platform as the business continues to grow internationally.

What you’ll be working on

• Building and improving customer-facing product experiences across the marketplace platform
• Developing frontend-heavy features while contributing across the full stack when needed
• Working on internal tooling and backend services that support marketplace operations
• Collaborating closely with product, design and growth teams to deliver high-impact features
• Contributing to technical discussions around architecture, scalability and product direction

What they’re looking for

• Strong experience as a full-stack engineer with a frontend bias, particularly with modern JavaScript / TypeScript frameworks
• Comfortable contributing across both frontend and backend services, with experience working with APIs and distributed systems
• Experience working with backend technologies such as Go / gRPC or similar backend stacks (desirable but not essential)
• Experience building and deploying applications in cloud environments such as GCP, AWS or Azure
• Product-focused mindset with experience building consumer-facing digital products or marketplace platforms, collaborating closely with product and non-technical teams

Nice to have

• Experience working in marketplace, SaaS or high-growth product environments
• Exposure to modern backend services and APIs
• Interest in building scalable platforms used by a global audience

You’ll be joining a product-led engineering team working on a platform that combines technology, commerce and creativity. The team values engineers who are comfortable owning features end-to-end and contributing to product decisions.
