Full Stack Polyglot Engineer – London

Founding Full Stack Polyglot Engineer – London | Up to £100k + Benefits + Shares

An early-stage, well-funded startup is looking for a Senior Full Stack Polyglot Engineer to help build the next generation of AI-driven control software.

If you want to be part of something from the ground up, where your decisions genuinely shape the product and technology, this is the kind of role that doesn’t come around often.

You’ll be working directly with the founding team to create multiple SaaS applications that use large language models and modern AI tools. This is a rare opportunity to have full ownership over the tech you use, the systems you design, and the future of the product itself.

They offer more than just a competitive salary and shares. You’ll get freedom and influence from day one. This is a supportive and transparent culture that values honesty over polish, and potential over perfection. You’ll move fast, grow quickly, and play a vital role in a mission that’s bold and technically ambitious.

The Polyglot Engineer should have experience in:

• Backend: Python, Golang, Node, Java, Kotlin (or any solid language)

• Frontend: JavaScript or TypeScript. With some basic React / Vue / Angular

• Cloud: GCP, AWS or Azure

• DevOps: CI/CD, GitHub, Jenkins

• Systems: Microservices, distributed architectures, Testing

• AI: LLMs, prompting, fine-tuning

If you’re excited by the idea of working in a small, ambitious team and having a big say in what gets built, please apply.
