Marketing Technology Lead

Marketing Technology Lead @ LemFi

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 millions of users across the globe, we process over $1B in monthly transactions to 30+ countries, proving that borders shouldn't limit financial opportunity.

The Role

You will be the architect of our performance engine. Your mission is to ensure that every dollar spent on global acquisition is measurable and that our conversion funnel is a "leaky-bucket-free" zone.

You will build the infrastructure that allows us to attribute a cross-border transfer back to its original source and optimise the path to "First Send." This is a hands-on, technical leadership role that sits at the intersection of Marketing, Engineering, and Data.

How You’ll Contribute

• Tracking & Infrastructure: Design and maintain multi-touch attribution (MTA) models and lead the transition to server-side tracking to ensure 100% accuracy in "Transaction Funded" events.
• Event Mapping & Taxonomy: Own the global event dictionary, ensuring that key milestones like "KYC_Approved" and "Transfer_Initiated" fire consistently across iOS, Android, and Web.
• Growth Optimisation: Manage the technical side of experimentation and architect "Liquidity Alerts" that trigger automated, personalized notifications based on real-time corridor rates.
• Incrementality & Modeling: Build automated dashboards to compare CAC against 90-day LTV by corridor and run "Lift Studies" to prove the true incremental value of our campaigns.
• Cross-Functional Bridge: Collaborate with Legal and Compliance on data privacy, while working with Creative and Product teams to optimize onboarding flows.

Who You Are

• Data-Driven & Skeptical: You don’t take dashboard numbers at face value; your first instinct is to verify tracking integrity before celebrating a high ROI.
• Strategic & Patient: You understand that in P2P remittance, the "First Transfer" can take days due to KYC, and you have the patience to map out long-tail attribution.
• Operationally Rigorous: You treat the MarTech stack like a product, maintaining clean documentation and ensuring app updates never break marketing automation.
• Adaptable: You thrive in a fast-paced fintech environment and can pivot from technical SDK audits to high-level strategic planning with ease.

What You’ll Bring

• Technical Expertise: High proficiency in SQL for raw data extraction and deep experience with MMPs (AppsFlyer, Branch) and CDPs (Segment).
• Domain Knowledge: Experience in Fintech or a regulated industry involving KYC requirements and mobile-first growth.
• Stack Implementation: Proven ability to build a MarTech stack from scratch or migrate legacy systems into a modern, unified architecture (e.g., Braze/Segment).
• Experimentation Logic: A solid grasp of statistical significance and experience managing the technical infrastructure for A/B testing (e.g., Optimizely, VWO).
• Engineering Literacy: The ability to audit app SDKs to ensure marketing trackers do not compromise app performance or security.

The Interview Process

• Chat with a Talent Partner (30 mins)
• Behaviours & Culture Interview (45 mins)
• Technical Assignment (60 mins presentation)
• Final Interview (30 mins)
