ABOUT US

We are building an AI-powered financial technology platform designed to simplify how people move, convert, and manage money across Africa.

Our product combines conversational AI, digital assets, and modern financial infrastructure to deliver intuitive financial experiences across messaging platforms, web, and mobile applications.

We are looking for a skilled, proactive, and product-focused Frontend Engineer with strong expertise in React, React Native, and TypeScript, alongside practical experience with Node.js and AI-powered applications.

This role is primarily focused on frontend and mobile application engineering, with additional responsibility for maintaining and improving existing conversational AI integrations and supporting application services.

We are looking for someone who can take ownership of existing systems, build polished user experiences, solve technical problems independently, and consistently deliver working software.

ROLE OBJECTIVE

Build, maintain, and improve the customer-facing applications and conversational interfaces powering our platform.

You will take ownership of our web and mobile frontend experiences, integrate existing backend APIs, and contribute to the development and improvement of our conversational AI infrastructure.

You will work closely with the founders, product team, and backend engineers to translate product requirements into reliable, secure, and intuitive applications.

The focus is on delivering functional, tested, production-ready features—not simply writing code or completing development activities.

KEY RESPONSIBILITIES

1. Frontend & Mobile Application Development

  • Build, maintain, and improve mobile applications using React Native and Expo.
  • Develop and maintain web applications using React and TypeScript.
  • Translate approved UI/UX designs into polished, responsive, and functional interfaces.

  • Implement authentication flows, navigation, forms, and interactive application features.
  • Develop conversational chat interfaces and transaction-related user experiences.
  • Integrate frontend applications with existing backend APIs.
  • Handle loading states, errors, network interruptions, and user feedback effectively.
  • Optimize application performance, responsiveness, and usability.
  • Support Android and iOS build, testing, and release processes.

2. Conversational AI & Node.js Integrations

Work with our existing conversational AI infrastructure to maintain and improve the applications and services supporting AI-powered customer interactions.

Responsibilities include:

  • Maintain and improve relevant Node.js/TypeScript application services.
  • Integrate and maintain LLM-powered functionality.

  • Troubleshoot errors across frontend, conversational services, and backend API connections.
  • Support existing WhatsApp-based conversational experiences.
  • Collaborate with backend engineers to ensure reliable integration with financial operations APIs.

You are not expected to train machine learning models or develop new foundational AI models.

However, practical ability to work with existing Node.js services and production AI integrations is important for this position.

3. API Integration & Application Reliability

  • Integrate REST APIs and other relevant application interfaces.
  • Implement secure authentication and session management.
  • Manage application state and asynchronous operations.
  • Handle API errors, timeouts, retries, and unexpected responses.
  • Ensure transaction-related interfaces display accurate information and statuses.
  • Collaborate with backend engineers to investigate integration issues.
  • Maintain reliable communication between frontend applications, conversational services, and core backend systems.
  • Follow appropriate security practices for sensitive financial and customer information.

Core wallet accounting, financial transaction processing, and ledger logic remain the responsibility of the financial backend engineering team.

4. Existing Application Maintenance

  • Maintain and improve existing web frontend applications.
  • Support frontend functionality within the company's back-office system.
  • Maintain and update the company landing page and related web interfaces.
  • Identify and resolve frontend bugs and usability issues.
  • Improve existing functionality where necessary.
  • Understand and document important parts of inherited codebases.
  • Ensure changes do not introduce avoidable regressions.

5. Testing, Debugging & Product Delivery

  • Write clean, reusable, and maintainable code.
  • Implement appropriate frontend and integration tests.
  • Diagnose and resolve application bugs.
  • Test features across relevant browsers and mobile devices.
  • Participate in code reviews and technical discussions.
  • Work with the product and QA team to verify completed functionality.
  • Maintain clear technical documentation.
  • Support application releases and post-release issue resolution.
  • Take ownership of assigned features from development through testing and delivery.

REQUIRED SKILLS & EXPERIENCE

WHAT SUCCESS LOOKS LIKE

YOUR FIRST 30 DAYS

Within your first 30 days, you should be able to:

  • Work effectively with the product and engineering teams to deliver features and contribute to stable product releases.
  • Take responsibility for assigned development tasks and deliver consistently with minimal supervision.

Performance will be assessed based on completed functionality, code quality, technical problem-solving, reliability, adherence to deadlines and measurable product improvements—not merely development activity.

Deliverables and expectations will be agreed based on product priorities, the state of the existing codebase and the availability of required backend APIs.
