Staff Engineer

LemFi (Series B) is building the go-to financial app for the Global South.

Moving to a new country shouldn’t mean starting from zero. That's why our team of 400+ spanning 20+ countries is building a financial ecosystem that helps immigrants stay connected to home, build stability, and create wealth regardless of where they are from or where they live.

What began as fast, affordable remittances is now evolving into a complete platform for multi-currency accounts, payments, credit, and long-term financial growth.

With over 2 million users across the globe, we process over $1.5B in monthly transactions to 30+ countries, proving that borders shouldn't limit financial opportunity.

The Role

You will be the technical engine behind LemFi’s Remittance Platform, a system that processes tens of millions of cross-border transactions every month. As a Staff Engineer, you aren’t just writing code; you are driving the architectural strategy that allows immigrants around the world to send money home safely and efficiently. You will tackle the most complex system challenges end-to-end, setting the benchmark for technical quality across the entire engineering organisation.

• Drive Technical Strategy: Guide architectural decisions from concept to production across multiple teams, ensuring our systems are scalable and well-informed.

• Establish Excellence: Set and uphold benchmarks for design, implementation, testing, reliability, and scalability across the organisation.

• Own Critical Components: Take hands-on ownership of high-stakes system components to set a gold standard for the team by example.

• Mentor and Amplify: Provide technical guidance to engineers and leads, removing blockers and bringing clarity to ambiguous challenges through strong communication.

• Collaborate Strategically: Partner with Product, Data, and Growth stakeholders to align our technical roadmap with broader company priorities.

• Evolve Standards: Shape company-wide engineering standards, continuously improving tooling and processes for long-term impact.
