Description

Full Stack Developer (Contract) Location: Stratford, London Contract: 3 Months Rate: £450/day (Inside IR35) What we're looking for: We're seeking an engineer, not just a coder—someone who understands how software works beyond writing code and can make sound technical decisions. Key requirements: ✅ Strong Full Stack development experience with deep knowledge of JavaScript/TypeScript ✅ Solid understanding of system architecture, software engineering principles, and system design ✅ Previous Java experience is highly desirable ✅ Hands-on experience with CI/CD pipelines ✅ Strong understanding of APIs and backend integrations ✅ Experience with observability, including metrics, logs, traces, latency, and monitoring ✅ Good understanding of distributed systems vs. microservices ✅ Experience explaining technical decisions, trade-offs, deployments, and system improvements ✅ Practical experience working with LLMs, including prompting, querying, and understanding their limitations ✅ Comfortable using AI as a development aid, while maintaining strong coding ability and engineering judgement—this role requires hands-on software engineering, not reliance on AI-generated code. This opportunity is ideal for developers who enjoy solving complex engineering challenges, building scalable systems, and taking ownership of the products they create. 📩 If you're interested or know someone who would be a great fit, please send me your CV or get in touch for more details.
