Salary

£60k-£90k + Bonus

Company Description

Profitable, privately funded UK property lender specializing in bridging and development finance

Job Description

As the founding engineering hire, you will build and own two greenfield products from the ground up: an internal loan management system integrating HubSpot CRM and a custom investor portal. Working directly with the founders within a new Innovation department, you will define the technical architecture and drive product-led growth.

Location

London, UK

Why this role is remarkable

• Take total ownership as the first engineering hire in a profitable, fast-moving business that is just launching its dedicated technology division.
• Influence the company’s trajectory by building a bespoke internal loan ecosystem and an external investor portal from scratch rather than maintaining legacy code.
• Work in a high-trust environment with direct access to co-founders and a technically proficient team, skipping the corporate ticket queue for real impact.

What You Will Do

• Architect and develop an end-to-end loan management system that connects HubSpot CRM with underwriting, completions, and loan monitoring workflows.
• Design and launch a secure investor portal to streamline fundraising, deal updates, and high-stakes investor communications.
• Make foundational technical decisions on the stack and infrastructure while collaborating with the Innovation team to translate business requirements into software.

The ideal candidate

• Possesses 1-5 years of professional full-stack development experience with a track record of building and shipping high-quality, functional products.
• Demonstrates strong conscientious engineering practices and the ability to work independently in a greenfield environment without needing a predefined spec.
• Has experience or interest in fintech, financial services, or CRM integrations (like HubSpot), combined with a desire for hybrid work in Camden, London.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
