Requirements

Must:
- I require 2+ years of professional backend development experience, preferably with Node.js and TypeScript. - A strong grasp of asynchronous programming, microservices, and event-driven architectures is essential. - You should have a solid understanding of testing, CI/CD, and cloud deployment workflows. - Practical experience with MongoDB or similar NoSQL databases is important. - I am looking for a problem-solver with strong communication skills and a collaborative mindset. - Bonus points if you have experience with message queues (Kafka, RabbitMQ), observability tooling, or DevOps-style environments.

Responsibilities

- You will architect, design, and build backend applications using Node.js (TypeScript) and NestJS. - Development of microservices and event-driven systems with asynchronous communication patterns will be part of your role. - Writing clean, maintainable, and well-tested code (unit + integration) will be expected. - You will design and optimize RESTful APIs with a strong focus on performance, reliability, and security. - Modeling and querying data efficiently with MongoDB (or similar NoSQL databases) will be your responsibility. - You will deploy and manage services on Google Cloud Platform (GCP) using CI/CD pipelines (GitHub Actions). - Troubleshooting and tuning performance across distributed systems will be part of your tasks. - Collaboration in an agile environment is key, as you will contribute to design reviews, planning sessions, and team discussions.

Description


I am offering an exciting opportunity to join a fast-growing AI startup that is transforming a trillion-pound industry through intelligent automation. You will have the chance to take ownership of key backend services that power our AI-driven platform. You will collaborate with teams across product, frontend, and AI to design, build, and scale backend systems that manage large-scale data, complex workflows, and real-time interactions. We offer a modern tech stack, including Node.js, TypeScript, NestJS, MongoDB, GCP, and CI/CD, along with equity and a competitive salary to reward the value you help create. You will work in a collaborative culture alongside passionate engineers, product thinkers, and AI specialists in a mission-driven environment aimed at transforming a traditional industry through automation and intelligent systems. The position is hybrid, based in London, with the flexibility to work remotely several days a week.
