Improving productivity in industry through ML based software development

Established companies have legacy systems and software that require years' experience to use it well or a bookshelf of manuals to operate it. When these systems are no longer fit-for-purpose, the usual response is to hire an IT consultancy on a slightly better system, but is there another way?

This growing start-up is tackling these problems by listening and discussing these business pain-points and developing bespoke software through their automated ML based platform. With VC funds already secured, they are growing their engineering team and are looking for their next hires.

Requirements:

• Top Computer Science education – likely a first class degree from Cambridge, Oxford, Imperial or similar and possible a PhD.
li>Commercial software engineering experience using modern typed Python, Docker and PostgreSQL. Most probably also used a compiled language like Go or Rust. Additional experience with modern frontend technologies would be desirable.

• Experience with AI / LLM techniques and models for professional projects or through substantial hobby projects.
• Excellent communication skills including knowledge of software architecture.

This is not your run-of-the-mill software company, and so interested candidates need to be naturally curious, engaged and fast to pick up new ideas. Previous experience working in a fast-growing software start-up would be advantageous.

On offer is an excellent remunerations package including enhanced pension, family covered private healthcare and flexible working including substantial hybrid options.
