Direct Answer

Node.js Developer salaries in the UK range from £34,000 (junior) to £580–£780/day (senior/lead). Node.js + TypeScript is the standard UK backend JavaScript stack in 2025. Fastify expertise (the modern alternative to Express) is emerging as a premium signal. Node.js + PostgreSQL + AWS combination is the most sought-after UK backend profile.

Market Outlook

Node.js developers are core to the UK software market — powering the majority of UK startup and SaaS backend APIs. TypeScript proficiency (standard expectation in 2025) and cloud architecture knowledge (AWS or Azure) command meaningful premiums.
