Senior Backend Engineer

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’s 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 hiring a Senior Backend Engineer to help us build and scale our backend systems as we continue to grow our customer base and expand the features of our product.

This is a chance to do some of the best work of your career in a supportive, no-ego environment

What You’ll Do

• Lead the development of backend features that support our customers and internal teams
• Design scalable solutions that take the end user into account – not just the backend
• Collaborate closely with other backend, frontend, and mobile engineers, as well as cross-functional stakeholders
• Drive projects through ambiguity and bring clarity where needed, taking initiative to move things forward

You’ll Succeed With

• 5+ years of hands-on experience with Ruby on Rails in a production environment
• A strong track record of building and shipping backend systems at pace, ideally in a high-growth startup or scale-up
• Experience leading projects with multiple stakeholders and engineers involved
• Experience or interest in GraphQL is a plus
• A collaborative, product-focused mindset – you care about solving real customer problems, not just technical ones
• Strong communication and the ability to bring clarity to complex or ambiguous problems
• Proactive curiosity – you ask questions, challenge assumptions, and continuously improve your craft
• A bias for action – you value delivering results over perfection
