Why We Exist

At Raylo, we’re on a mission to accelerate the move to a circular economy. The only way customers and manufacturers will make that shift is if it’s simple and cost-effective - this is where we come in. We’re building a category-defining global subscription infrastructure, making premium tech accessible and affordable for both consumers and businesses. With over 180,000 subscribers in the UK and growth accelerating, we’ve proven the demand for a smarter, more sustainable way to access technology.

Raylo is a fast-growing and profitable company, backed by global investors including Macquarie, NatWest, and Channel 4 Ventures.

We are proud to have been selected for Endeavor’s network in 2024, underscoring our role as a high-impact, mission-driven business with global ambitions. And in 2025, we were recognised as part of Tech Nation’s UK Future Fifty programme.  

We have been B-Corp certified since 2021 and were recently acknowledged by S&P Global for the positive impact of our circular business model via a Green Financing with NatWest.

At Raylo, performance matters. We set ambitious goals, move fast, and hold ourselves to a high standard, because our mission is too important to settle for less.

Our Core Values

💡 Be deeply curious – We thrive on innovation through diverse approaches, views, and people.

👟 Walk in your customer’s shoes – To build the best products and make the best decisions for the long term, we must figure out what our customers need, not just what they want.

🎯 Focus and execute – We have a big vision, but we believe in nailing the most important problems first.

💥 Be gritty – Only gritty teams succeed. Our individual ownership, passion, and perseverance mean we’re a team through thick and thin.

What to Expect

We’re looking for an ambitious Head of Data Science to join Raylo and lead the development of our advanced modelling capabilities. Raylo has built a strong data foundation over the past five years, with robust analytics and data engineering powering commercial decision-making across the business. In this role, you’ll take that foundation to the next level by designing, building and deploying predictive models that directly influence some of the most important drivers of Raylo’s growth - from credit risk and customer retention to personalised recommendations.

You’ll work closely with teams across the business to identify high impact opportunities for machine learning and advanced analytics, taking projects end-to-end from idea through to production deployment and monitoring. This role combines deep technical expertise and true commercial partnership - translating complex modelling approaches into real business outcomes. Initially starting as a hands-on individual contributor, you’ll also play a key role in shaping and growing Raylo’s data science function as our modelling needs expand.

What You’ll Do

  • Reporting to the VP of Strategy & Analytics, you’ll define and lead Raylo’s data science capability, building advanced predictive models that drive some of the business’s most important commercial decisions.
  • You’ll design, build and deploy production-grade machine learning models - from credit risk and churn prediction to recommendation systems - turning Raylo’s rich data into actionable insight and measurable business impact.
  • You’ll partner closely with teams across product, engineering, risk, operations and commercial to identify high-impact opportunities for advanced modelling and take them end-to-end from ideation through deployment and monitoring.
  • You’ll combine deep technical expertise with strong communication skills, translating complex modelling approaches into clear commercial benefits
  • Starting as a hands-on technical leader, you’ll play a key role in shaping the long-term data science roadmap at Raylo and building out a high-performing data science team

You’ll Succeed With

  • A proven track record with 7+ years of experience in data science and predictive modelling
  • A 2:1 or higher from a top university, preferably in a STEM or quantitative discipline.
  • Using your technical skills to build state-of-the-art ML models and deploy them in production
  • The desire to build, coach and motivate a broader function while continuing to deliver on high-quality IC projects
  • Collaborating in a fast-paced environment across the business with diverse skill sets and personality types. You have great stakeholder management skills and love using your analytical skills to champion data-driven decision-making and educate others.
  • Taking responsibility and ownership for the work in the entire area - if you’re not getting it done, no one is

Where to Advertise AI Jobs in the UK (2026 Guide)

Where to advertise AI jobs UK in 2026: the specialist boards and communities that reach AI engineers, ML scientists and applied research talent in the UK. The candidate pool is small, highly informed and in demand across multiple sectors simultaneously. General job boards reach a broad audience but lack the specificity that AI professionals expect — and the filtering mechanisms they rely on. Specialist platforms, direct outreach and academic channels each serve a different part of the market. This guide, published by ArtificialIntelligenceJobs.co.uk, covers where to advertise AI roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about time-to-hire across different role types.

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

AI Jobs UK 2026: roles, salaries and the generative AI, machine learning and applied AI hiring trends shaping UK artificial intelligence careers. Artificial intelligence is creating jobs faster than the market can name them. New roles are appearing every quarter, existing titles are splitting into specialisms, and the technologies underpinning it all are evolving at a pace that makes even last year's job descriptions feel dated. For job seekers, this presents a genuinely unusual challenge. In most industries, career planning means understanding a relatively stable landscape and working out where you fit within it. In AI, the landscape itself is being redrawn in real time. The roles with the most hiring activity in 2028 may not yet have a widely agreed job title in 2026. That's not a reason to feel overwhelmed — it's a reason to get informed. The candidates who thrive in this market aren't necessarily those with the longest CVs or the most credentials. They're the ones who understand the direction of travel: which skills are gaining value, which technologies are driving employer decisions, and how the definition of an "AI job" is expanding well beyond the tech sector. This article breaks down what the UK AI jobs market is likely to look like over the next three years — covering emerging job titles, the technologies reshaping hiring, the skills employers are prioritising, and how to position yourself ahead of the curve rather than behind it.
