Back End Developer

Senior Backend Software Engineer - London (Hybrid) Equity + Competitive Salary

Join a fast-growing AI startup transforming a trillion-pound industry through intelligent automation.

 

We're building the next generation of workflow technology - streamlining complex, manual processes and empowering professionals to focus on the work that truly matters.

 

If you love solving deep technical problems, shaping architecture, and seeing your code have a real-world impact, this is a chance to build something meaningful from the ground up.

 

The Role

 

We're looking for a Senior Backend Engineer to take ownership of key backend services that power our AI-driven platform.

 

You'll work closely with product, frontend, and AI teams to design, build, and scale backend systems that handle large-scale data, complex workflows, and real-time interactions.

 

You'll join a small, high-calibre team where your ideas genuinely shape the direction of the product and the company.

 

What You'll Be Doing

 

  • Architect, design, and build backend applications using Node.js (TypeScript) and NestJS.
  • Develop microservices and event-driven systems with asynchronous communication patterns.
  • Write clean, maintainable, and well-tested code (unit + integration).
  • Design and optimise RESTful APIs with a strong focus on performance, reliability, and security.
  • Model and query data efficiently with MongoDB (or similar NoSQL databases).
  • Deploy and manage services on Google Cloud Platform (GCP) using CI/CD pipelines (GitHub Actions).
  • Troubleshoot and tune performance across distributed systems.
  • Collaborate in an agile environment, contributing to design reviews, planning sessions, and team discussions.

 

What We're Looking For

 

  • 2+ years of professional backend development experience (preferably with Node.js + TypeScript).
  • Strong grasp of asynchronous programming, microservices, and event-driven architectures.
  • Solid understanding of testing, CI/CD, and cloud deployment workflows.
  • Practical experience with MongoDB or similar NoSQL databases.
  • Problem-solver with strong communication skills and a collaborative mindset.
  • Bonus: experience with message queues (Kafka, RabbitMQ), observability tooling, or DevOps-style environments.

 

Why You'll Love It Here

 

  • Impact & Ownership - You'll own core backend systems and shape architectural decisions.
  • Modern Tech Stack - Node.js, TypeScript, NestJS, MongoDB, GCP, CI/CD.
  • Equity + Competitive Salary - Get rewarded for the value you help create.
  • Collaborative Culture - Work alongside passionate engineers, product thinkers, and AI specialists.
  • Mission-Driven - Help transform a traditional industry through automation and intelligent systems.
  • Hybrid Model - Based in London with flexibility to work remotely several days a week.

 

If you're excited by building elegant systems that make a tangible difference - and want to grow in a fast-moving, high-ownership environment - we'd love to hear from you.
