Company: Loop Recruitment
Apply for the Senior Software Engineer
Location: London
Job Description:

React.js | TypeScript | Next.js | Product & AI-Focused

We’re partnering with an ambitious fintech scale-up entering a major growth phase as it expands its product offering and invests heavily in technology, AI, and customer experience.

This isn’t a role for someone who simply wants to build features.

We’re looking for an engineer who wants to help shape products, influence technical direction, contribute to business outcomes, and play a key role in how a scaling engineering organisation evolves.

As one of the early senior hires, you’ll work closely with engineering leadership, product, design, and AI specialists to build customer-facing platforms that make complex financial journeys faster, simpler, and more transparent.

What You’ll Be Doing

  • Building and scaling modern frontend applications using React, TypeScript, and Next.js
  • Taking ownership of key product areas from concept through delivery
  • Collaborating closely with Product and Design to shape user experiences and influence roadmap decisions
  • Helping define frontend architecture, engineering standards, and best practices
  • Exploring and championing practical uses of AI across both products and engineering workflows
  • Contributing to technical strategy as the business grows and scales its engineering capability
  • Acting as a collaborative senior voice within a small, high-impact team

We’re Looking For Someone Who

  • Has strong commercial experience with React, TypeScript, Next.js, and modern frontend development
  • Enjoys working closely with Product, Design, and non-technical stakeholders
  • Thinks beyond implementation and cares about customer outcomes
  • Can demonstrate influence on product direction, user experience, or business decisions
  • Is excited by AI and can identify opportunities to leverage emerging technologies in meaningful ways
  • Thrives in scale-up environments where ownership and initiative are expected
  • Wants to help shape a growing engineering culture rather than simply work within one
  • Has genuine curiosity about fintech, lending, and the challenges of modern financial products

Why Join?

  • Join during a critical growth phase with significant investment in technology
  • Influence both product and technical direction from an early stage
  • Work alongside product, design, and AI specialists on meaningful customer problems
  • Opportunity to grow with the business as the engineering organisation scales
  • High levels of autonomy, ownership, and visibility
  • Help define how engineering operates as the company enters its next stage of growth

This role would suit a technically strong engineer who enjoys wearing multiple hats, contributing beyond code, and helping build not just software, but the future direction of a growing fintech business.
