About Lendable

Lendable is on a mission to build the world's best technology to help people get credit and save money. We're building one of the world’s leading fintech companies and are off to a strong start:

  • One of the UK’s most exciting unicorns with a team of over 800 people

  • Among the fastest-growing tech companies in the UK

  • Profitable since 2017

  • Backed by top investors including Balderton Capital and Goldman Sachs

  • Loved by customers with the best reviews in the market (4.9 across 10,000s of reviews on Trustpilot)

So far, we’ve rebuilt the Big Three consumer finance products from scratch: loans, credit cards and car finance. We get money into our customers’ hands in minutes instead of days.

We’re growing fast, and there’s a lot more to do: we’re going after the two biggest Western markets (UK and US) where trillions worth of financial products are held by big banks with dated systems and painful processes.

Join us if you want to

  1. Take ownership: you are trusted to make decisions that drive a material impact on the direction and success of Lendable from day 1

  2. Work in small teams of exceptional people: Lendies are relentlessly resourceful. We challenge the status quo to solve problems and find smarter solutions

  3. Build the best technology in-house: we use new data sources, machine learning and AI to make machines do the heavy lifting

Operations is roughly half of Lendable's people. Central Ops Engineering is a small product engineering team that builds the tooling to help keep back office operations lean and efficient, while maintaining good customer outcomes.

We're hiring a senior product engineer who can own and deliver large problems in that space. You'll build the internal web apps and automations that agents use every day, and help shape how the team uses AI coding tools.

What you'll work on

Current problems include:

  • Complaints: we've already made handling much more efficient for officers, and are continuing to push on this.

  • Fraud and Fincrime: putting the signals an investigator needs into one place.

  • Quality assurance: using AI to review far more calls than a QA team can sample, and directing coaching to the agents who need it.

How we work

We use Claude Code, Codex, Augment and other AI tools every day. They've tripled our productivity, and we want you to help decide where we take that next. You'll hand real work to coding agents and take responsibility for what ships.

You'll work directly with ops agents and their managers, and with Product. Data Science and Analytics own the models and prompt engineering, and you'll build the tools that put their work in front of agents.

Who you are

  • An experienced product engineer with a strong track record of delivering practical, full-stack solutions on modern technology

  • Comfortable with ambiguity and focused on business outcomes, looking beyond the stated requirements to address the underlying problem

  • Experienced in shaping team ways of working and mentoring other engineers

  • Enthusiastic about AI-assisted development, ideally with a record of using it to improve how your team delivers

Our tech stack

This is what we use today, to give you a feel for the work. If your tech stack is different, we'd still like to hear from you: we've successfully onboarded engineers from different stacks in the past.

  • Backend: Python and FastAPI

  • Frontend: React, Next.js and Tailwind

  • Infrastructure: AWS, Docker, Kubernetes, Argo and Terraform

  • Data: SQL & Snowflake

  • Patterns: Domain Driven Design, message-driven systems and event sourcing

Interview process

  1. Intro call with Talent (30 min).

  2. Coding exercise in your own time ([2-3 hours max]). It's a small internal-tool problem, and you should use AI tools as you normally would.

  3. Technical interview (60 min). You'll walk us through your exercise, then we'll change the requirements and extend it together.

  4. Culture and behavioural interview (60 min), with time for your questions.

Life at Lendable

  • Winning team: the opportunity to scale up one of the world’s most successful fintech companies

  • Flexible working: flexible approach tailored to each role. Hybrid roles require three days in-office weekly; fully remote roles include regular opportunities for in-person connection through socials and off-sites

  • Socials & connection: opportunities and events to come together, socialise, and get to know each other beyond the office walls

  • Health coverage: support for your physical and mental wellbeing, including private health cover

  • Retirement & savings: long-term financial wellbeing through retirement savings plans

Prompt engineeringClaudeClaude CodeCodex

Questions you could be asked

  1. How do you structure and test a prompt to get consistent output from a language model?
  2. Walk me through how you've used Claude in your day-to-day work.
  3. What are the limits of Claude Code that you've run into, and how did you work around them?
  4. What's a project where you used Codex hands-on?
  5. This role expects you to use AI tools as part of the job. Which ones have you used, and for what?

Adapt your resume

  • List these exact terms on your resume: Prompt engineering, Claude, Claude Code, and Codex. An applicant tracking system matches the wording, not the idea.
  • Attach one line of real, concrete experience to at least one of them. A tool named with nothing behind it rarely survives a human read.
  • Put the AI tool in a bullet point about what you did, not just in a skills list. This role treats it as a required part of the job.
