Senior Product Engineer
Lendable
UK fintech marketplace lending for consumers
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.
Take ownership: you are trusted to make decisions that drive a material impact on the direction and success of Lendable from day 1
Work in small teams of exceptional people: Lendies are relentlessly resourceful. We challenge the status quo to solve problems and find smarter solutions
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.
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.
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.
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
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
Intro call with Talent (30 min).
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.
Technical interview (60 min). You'll walk us through your exercise, then we'll change the requirements and extend it together.
Culture and behavioural interview (60 min), with time for your questions.
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
Employee referral programme: earn a competitive bonus when you refer successful new team members
Office meals & snacks: enjoy a fully stocked kitchen, plus complimentary lunches prepared by in-house chefs on in-office days at select locations
Sustainable commuting: cycle-to-work and electric vehicle salary sacrifice schemes available in select locations

Lendable is a UK fintech that connects borrowers with institutional investors to fund unsecured personal loans, operating as a two-sided marketplace rather than lending from its own balance sheet. Its products are issued digitally, with AI/ML credit scoring that analyzes many data points beyond traditional credit scores to deliver instant decisions and fast funding, while eligibility checks won’t affect credit scores. In addition to personal loans, it offers Autolend car finance and Zable credit products (including in the US). The company differentiates itself by using automated credit decisions and sourcing capital from institutions to bypass traditional banking bottlenecks, with a goal of expanding access to consumer credit for a broad segment of UK residents and growing its product suite.
