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 that’s building products to make sense of massive data streams. You’ll 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, you’ll 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 quality
What you’ll 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 we’re 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 you’ll have to be comfortable with the backend nature of the role
If you’re a Senior Software Engineer who likes solving real problems, shaping a product, and being part of something early – this is worth a chat
