Job Description

Senior Software Engineer Node.js / AWS / React London (Hybrid, 3 days onsite)

Are you the kind of Senior Software Engineer who enjoys taking something fast-and-scrappy and turning it into something scalable, elegant, and genuinely robust?

This is a chance for a Senior Software Engineer to join a small, but ambitious tech-for-good / IoT startup based in the London City Centre thats building products to make sense of massive data streams. Youll be part of a tight-knit team (around ten people total, five software engineers), working on a genuinely greenfield platform with a modern stack and zero legacy

The focus now is on maturing the codebase re-architecting, refactoring, testing, and scaling. As a Senior Software Engineer, youll play a key role in helping the team evolve from early-stage speed to long-term stability, with the freedom to influence both product direction and engineering qualit

What youll be doing:

  • Building and scaling a Node.js application that sits at the core of the product
  • Designing and implementing new features for different sectors and use cases
  • Helping drive improvements in code quality, architecture, and testing practices
  • Working closely with product and engineering to prioritise, shape, and deliver features
  • Introducing best practices and guiding a shift towards cleaner, more maintainable code

What were looking for:

  • Strong hands-on experience with Node.js backend software development
  • Comfortable working across or picking up other tech as needed ie AWS, React etc (If you have experience with AWS & React, that is a bonus)
  • Enthusiasm for writing clean, tested, production-ready code
  • Experience (or interest) in data-heavy systems, IoT, or connected devices
  • Ultimately, this is a backend focussed position, so as a Senior Software Engineer youll have to be comfortable with the backend nature of the role

If youre a Senior Software Engineer who likes solving real problems, shaping a product, and being part of something early (and yes, you'll get equity within the business too) then this is worth a chat
