About the team


In our Professional and Financial Services Business unit, we bring everything we have learned in more than a decade of Applied AI, and use it to help our clients navigate a rapidly changing landscape.


We develop and embed AI solutions which help financial institutions become more efficient, enhance customer experience, and find the commercial upside in uncertain markets. Within the constraints of a highly regulated industry, we see so much opportunity for impactful innovation and are proud to set the gold-standard for marrying technical excellence with safe deployment.

About the role

As a Senior Full Stack Software Engineer, you will be a technical anchor within our Professional & Financial Services team, leading the development of sophisticated platforms that visualise complex data science insights and bridging the gap between AI research and production-grade software.

You will have the autonomy to own the entire technical stack, driving architectural decisions and mentoring others to ensure we ship scalable, high-performance systems that transform how our customers interact with Machine Learning.

What you'll be doing:

  • Leading the architecture and design of complex projects to ensure they are robust, scalable, and aligned with long-term business needs.

  • Creating reliable, reusable, and high-performance frontend and backend systems that facilitate the seamless delivery of AI-powered insights.

  • Guiding engineers within cross-functional teams of Data Scientists and Product Managers to deliver technically sophisticated, high-impact systems.

  • Mentoring and managing more junior engineers on the team, fostering a culture of technical excellence and continuous professional growth.

  • Acting as the primary authority for engineering across the full stack, setting the standard for code quality and best practices.

  • Providing deep technical expertise to our customers, translating their most unique business challenges into viable, production-ready software solutions.

  • Balancing rapid prototyping with the requirement to ship and maintain large-scale products in a dynamic, fast-paced environment.

Who we're looking for:

  • You possess deep technical mastery in TypeScript and modern frontend frameworks like React or Vue, alongside significant experience in backend Python or TypeScript ecosystems.

  • You have a proven track record of leading the architecture of complex software projects and deploying them successfully into cloud environments like AWS, Azure, or GCP.

  • You bring extensive experience with containerisation and infrastructure-as-code, including tools like Docker, Kubernetes, or Terraform, to ensure reliable software delivery.

  • You are an expert problem-solver who can debug complex, full-stack issues and maintain high standards for testing using frameworks like Jest or Cypress.

  • You thrive on autonomy and ownership, with the entrepreneurial drive to take a vague problem statement through to a polished, high-impact execution.

  • You are a compelling collaborator and mentor who can effectively communicate technical strategy to both internal multidisciplinary teams and external high-level stakeholders..

Our Recruitment Ethos

We aim to grow the best team - not the most similar one. We know that diversity of individuals fosters diversity of thought, and that strengthens our principle of seeking truth. And we know from experience that diverse teams deliver better work, relevant to the world in which we live. We’re united by a deep intellectual curiosity and desire to use our abilities for measurable positive impact.

Where to Advertise Machine Learning Jobs in the UK (2026 Guide)

Advertising machine learning jobs in the UK requires a different approach to most technical hiring. The candidate pool is small, highly specialised and in demand across AI labs, financial services, healthcare, autonomous systems and consumer technology simultaneously. Machine learning engineers and researchers move between roles through professional networks, conference communities and specialist platforms — not general job boards where ML roles compete with unrelated software engineering positions for the same audience. This guide, published by MachineLearningJobs.co.uk, covers where to advertise machine learning roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

Machine Learning Jobs UK 2026: What to Expect Over the Next 3 Years

Machine learning has undergone a transformation that few technology disciplines can match. In the space of three years it has moved from a specialism sitting at the edges of most organisations' technology strategies to a capability that sits at the centre of them. The tools have changed, the expectations have shifted, and the range of industries treating machine learning as a core business function — rather than an experimental one — has expanded dramatically. For job seekers, this creates both opportunity and complexity in roughly equal measure. The machine learning jobs market of 2026 is significantly larger than it was three years ago, but it is also significantly more demanding. Employers have developed more sophisticated expectations, the technical bar for specialist roles has risen, and the landscape of tools, frameworks, and architectural patterns that practitioners are expected to know has broadened considerably. The candidates who will thrive over the next three years are those who understand where the discipline is heading — which specialisms are attracting the most investment, which technologies are reshaping what machine learning engineers and researchers are expected to build, and how the definition of a machine learning career is evolving beyond the model-building core toward a much wider range of roles across the full ML lifecycle. This article breaks down what the UK machine learning jobs market is likely to look like through to 2028 — covering the titles emerging right now, the technologies driving employer demand, the skills that will matter most, and how to position your career ahead of the curve.

New Machine Learning Employers to Watch in 2026: UK and Global Companies Driving ML Innovation
