Job description

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
• 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
• 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
• 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

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