Job description

We're on a mission to back the UK's small businesses like no one else

Small businesses are the backbone of the economy, and we're here to help them win. We've built a platform that uses clever data to get them the funding they need in minutes, not weeks.

At Funding Circle, we have the restless energy of a fintech start-up with the stability of a public company. It's a unique mix that gives Circlers the autonomy to take ownership and the scale to make an impact that truly counts.

We're a high-performing team that chooses to lift each other up. We challenge, we champion, and we have each other's backs - because we know that when we stand together, we move faster and build better.

The impact is real: Last year alone, the businesses on our platform generated £7.2bn for the UK economy.

London (Hybrid) | 2 days in the office | Competitive Salary + Benefits

The role

We are looking for an experienced Staff Engineer with an excellent track record of technical leadership for our Product Engineering team.

The role sits within our Multi-Product Experiences Engineering Group, providing technical leadership for the area responsible for the multi-product capabilities used by internal and external customers to browse, apply for and manage Funding Circle's class-leading credit products. Staff Engineers are amongst the most senior leaders we have within our Technology function and as such are responsible for raising the bar and enabling us to achieve the incredible.

As a Staff Engineer within our MPX domain you'll:

• Collaborate with product leadership early to understand the business goals and shape the technical direction to deliver on it. You translate this into a target system and data architecture with clear milestones to iterate towards it
• Have strong technical documentation skills and are able to write clear and thorough technical designs and standards
• Have high standards, drive continuous improvement, and take others on the journey to be even better
• Proactively identify and leverage the latest Generative AI tools and techniques to drive innovation and transform our engineering processes, helping the organisation become fully "AI Native."
• Actively coach Lead Engineers, giving them feedback on their solutions, and guardrails for making decisions. You play an important part in their personal development through mentorship and are a role model for aspiring Staff Engineers
• Perform deep-dives and troubleshoot issues in a hands-on capacity, but seek to enable the teams rather than becoming a dependency for future issues.
• Interact with different stakeholders and present technology solutions, risks and tradeoffs to any audience across Funding Circle, demonstrating the ability to influence without requiring reporting authority to do so
• Take accountability for high-level solution design and technology decisions within your Group
• Have sound commercial acumen and a solid understanding of how tech drives the top and bottom line. Your impact is connected to customer and commercial outcomes
• Represent Funding Circle externally at events, leveraging your network to share industry trends and insight, as well as attracting talent to Funding Circle.

What we're looking for

• A curious mindset and an ability to continuously improve the Technology function
• An engineering leader who can lead on solving high-level problems, whilst also deep-diving into technical challenges in a hands-on capacity
• Strong technical documentation skills
• Strong communication skills
• Experience in at least one major Programming language (e.g. Python, Ruby, Java)
• A strong fundamental programmer (data structures, algorithms)
• Familiar with developing on Unix/Linux
• Knowledgeable of Agile, Scrum, BDD, TDD and CI/CD
• Experienced in delivering mission-critical, high-value products, and services
• A strong passion for and proven experience in adopting and applying emerging technologies, particularly Generative AI, to solve complex engineering challenges and drive transformational change across an organisation.
• We're building a place where everyone truly feels they belong. Even if your past experience doesn't align perfectly with every requirement, we'd still love to hear from you.

Why join us

We back you to build an incredible career and by joining us, you'll be part of one of The Sunday Times Best Companies to Work For 2026! As a flexible-first employer, we use a 'best of both' approach. We'll see you in our London office to collaborate - with barista coffee and subsidised Just Eat lunches on us!
