Senior Node.js Engineer
Senior Node.js Engineer - AI-Powered Publishing Platform
Day Rate Contract | 6 Months
We build digital products for some of the UK's most recognised brands, and we're looking for a Senior Node.js Engineer to join us on an exciting client engagement in the media sector.
You'll be contracted to Hedgehog Lab, working embedded within a major UK media client's engineering team. Outside IR35.
This is backend-heavy Node.js and TypeScript work. If your background is primarily frontend React, this isn't the right fit.
The Role
You'll work on a proprietary digital publishing platform that powers AI-driven text, audio and video content services for one of the UK's leading media businesses. You'll design and build APIs, integrate internal systems with third-party platforms, and contribute to AI-powered and agentic workflows running in live production.
What You'll Be Doing
Developing and maintaining JavaScript APIs and services using Node.js and TypeScript at scale
Building and integrating RAG pipelines and multi-step AI-orchestrated workflows
Working with structured and unstructured data across MySQL, MongoDB, and blob storage
Deploying and operating services on AWS, including Bedrock, OpenSearch, and CI/CD pipelines
Writing reusable, performant, well-tested code with automated test coverage
Collaborating with a Delivery Manager and Product Owner on planning and delivery
What We're Looking For
Strong Node.js + TypeScript API and backend development -- this is not a frontend role
Proven experience on large-scale projects where senior-level judgement was required
Solid AWS background: cloud architecture, deployment, and CI/CD
Hands-on experience with RAG pipelines and LLM integration patterns
Comfort working across mixed data formats and storage types
AWS Bedrock and vector/semantic search (e.g. OpenSearch) experience is a genuine advantage
Interested?
