Principal Software Engineer

London

Most engineering roles promise impact. Few offer the opportunity to solve genuinely novel technical problems while helping define an entirely new category of software.

As an experienced engineer you want to work on challenges that are both intellectually demanding and commercially significant. You will join a small team tackling problems that sit at the intersection of artificial intelligence, software engineering, and enterprise transformation, with the freedom to influence both the technology and the direction of the product.

This is an opportunity to work on systems that must understand and reason about some of the most complex business environments in the world. Rather than optimising a small part of an existing product, you will help create technology that changes how large organisations operate and evolve, forever.

There is substantial ownership from day one. Decisions are made by the people closest to the problem, and engineers are trusted to shape architecture, product direction, and technical strategy. Your work will be visible, consequential, and deployed in environments where successful outcomes create measurable value at scale.

This is an environment where you’ll be surrounded by ambitious, highly capable colleagues who are motivated by solving difficult problems rather than maintaining the status quo. The environment is collaborative, intellectually rigorous, and designed for people who enjoy learning quickly and pushing the boundaries of what is possible. A low ego environment where it is about coming together to solve problems by shipping high quality code.

For engineers interested in artificial intelligence, this role provides the opportunity to work beyond experimentation and prototypes. You will build production systems that apply AI to real-world complexity and deliver tangible results for major organisations. The technical challenges are substantial, the feedback loops are fast, and the impact is immediate.

As the company grows, there will be significant opportunities to expand your influence, develop as a technical leader, and help build both the engineering culture and the technology platform. You will join at a stage where exceptional contributions are highly visible and where your work can have a lasting effect on the trajectory of the business.

If you are looking for a role that combines technical ambition, meaningful ownership, exceptional colleagues, and the opportunity to work on problems that few engineers encounter in their careers, we would like to hear from you.
