Senior Backend Engineer in London

At Raylo, we’re on a mission to accelerate the move to a circular economy. 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 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.

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. You’ll be joining a collaborative and talented team, working cross-functionally with engineers, product managers, and commercial teams to create real impact across the business.

You’ll play a key role in designing and delivering high-quality backend features that support both customer-facing journeys and internal business systems, such as supply chain and operations. Your work will directly contribute to our ability to serve more customers, more efficiently – and will help drive growth across our core platform.

You’ll be joining a team that values autonomy, fast iteration, and tackling meaningful challenges. You’ll have the freedom to experiment, propose new ideas, and take ownership of projects from concept to deployment.

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.
• Contribute to the team’s technical direction, including design discussions, code reviews, and mentoring.
• Participate in our engineering rota, helping to investigate and resolve production issues.
• Deploy your own code frequently – we empower engineers to take ownership and ship often, rather than having a separate devops team.
• Support a culture of learning, pairing, and curiosity to continuously raise the technical bar and succeed together.

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.
