About Tembo

At Tembo, we’re on a mission to make home happen — helping people buy their first home, remortgage, move up the ladder, and save smarter towards homeownership.

We’re tackling one of the biggest challenges of our generation: access to homeownership. Through innovative mortgage products, affordability schemes, and savings tools like our Lifetime ISA and HomeSaver, we help people who’ve been locked out of the property ladder finally get the keys to their own place.

Our work directly changes lives, every single day — and that sense of impact is what drives everything we do.

We’re proud to be:

• ⭐ 4.9-rated on Trustpilot, with every review celebrated
• 💸 Well funded by Goodwater Capital, Aviva, McPike Family Global Office, Ascension, Love Ventures, and ethical backers including Fair by Design, Barrow Cadbury, Joseph Rowntree Foundation, and Big Society Capital

The Role

We’re looking for a Frontend Lead Engineer to own and evolve our web and app experiences. This is a senior, hands-on engineering leadership role. You’ll take ownership of our frontend codebases, principles, and delivery — while working insanely closely with product and design to ship high-quality, customer-critical features.

Our primary app codebases are React Native, with React and Next.js used across the wider organisation. You’ll be a key technical leader in the business, setting the bar for quality, collaboration, and reliability in a product that handles real money and real lives.

What You’ll Be Doing

Technical Ownership

• Own the frontend architecture across our mobile apps and web surfaces
• Set and evolve standards for code quality, structure, testing, and performance
• Make pragmatic decisions around trade-offs, technical debt, and long-term maintainability
• Own frontend release processes, including mobile app store releases and hotfixes

Product Collaboration

• Work extremely closely with our CPO and Lead Product Designer to shape product direction
• Translate product ideas into well-scoped, deliverable technical plans
• Act as a strong voice for feasibility, quality, and customer impact during product discovery

Quality & Reliability

• Champion a strong testing culture (unit, integration, E2E)
• Ensure frontend reliability, performance, and crash-free experiences
• Take responsibility for bugs, incidents, and regressions — and build systems to prevent them

Team Leadership & Coaching

• Coach and mentor frontend engineers, helping them grow technically and professionally
• Lead by example through high-quality, hands-on contribution
• Foster a collaborative, high-trust engineering culture
• Improve team processes, delivery cadence, and developer experience

Continuous Improvement

• Identify opportunities to improve tooling, workflows, and shared frontend foundations
• Introduce better observability, monitoring, and debugging practices on the frontend
• Keep up with the React / React Native ecosystem and bring back what’s genuinely useful

About You

• 6+ years of professional frontend experience, with deep expertise in React and React Native
• Proven experience owning and scaling frontend codebases in production
• Strong testing mindset — you care deeply about quality and correctness
• Excellent collaborator who enjoys working closely with product and design
• Comfortable leading others while remaining hands-on
• Experience shipping and maintaining mobile apps in production environments
• Calm, pragmatic decision-maker who understands trade-offs in fast-moving teams
• Startup mindset: you move quickly, take responsibility, and improve things rather than waiting for permission

Bonus points for:

• Fintech or regulated-industry experience
• Experience with performance optimisation, error tracking, and analytics
• Experience building or contributing to design systems
• Familiarity with feature flags, A/B testing, or experiment-driven development

Why Join Tembo?

• Do genuinely meaningful work that changes people’s lives
• Work alongside smart, mission-driven colleagues who care deeply about customers
• Remote-first environment with a high degree of trust and ownership
• Recently relaunched benefits package, including:
• Enhanced parental benefits
• Health insurance
• Your birthday off
• An abroad company away day (Mallorca here we come 🌴)

We’re committed to diversity and inclusion and welcome applications from people of all backgrounds.
