Full-Stack Javascript Developer in Guildford

You'll be a senior developer on our in-house travel management platform, working across the full stack — from React frontends to Node.js APIs and background processing services that handle live travel data. The platform spans Linux and Windows environments, including containerised services running on Docker. The role involves real-time problem diagnosis, complex data transformation across multiple databases, and a high degree of autonomy. You'll be expected to own technical decisions, independently investigate and resolve issues across the entire stack, and operate as a trusted point of escalation when things go wrong. This is a hands-on technical role with genuine responsibility.

Skills & Experience:

• 3+ years commercial experience with Node.js and TypeScript
• Strong SQL skills — complex queries, relational schemas, multi-database environments (PostgreSQL and/or MS SQL Server)
• React (hooks, functional components)
• Experience transforming and mapping complex data structures (XML, JSON)
• Git — confident with branching, conflict resolution
• Familiarity with NestJS, tRPC, or similar API frameworks is a strong plus
• Experience with background processing patterns (queues, cron jobs, webhooks) is highly valued

Key Responsibilities:

• Build and maintain features across React frontends and Node.js/NestJS APIs
• Develop and support background processing services that ingest and transform travel data from external systems
• Write and optimise complex SQL across PostgreSQL and MS SQL Server databases
• Investigate and resolve production issues end-to-end — from browser through API to database and background processors
• Drive forward platform modernisation initiatives as they are prioritised

Please note that this role requires a security clearance process (you must have lived in the UK for 5 consecutive years to be eligible) and a DBS check. Do not apply if you are not willing to undergo these conditional background checks, this continually applies during the course of your employment.
