Senior Software Engineer

About the Role

We're looking for a senior engineer to be the technical backbone of Pronto. You'll work hands-on across our entire stack — from our Expo (React Native) mobile apps to our Supabase backend — building the rideshare platform that Central Africa deserves.

This isn't a management role. You'll write code every day, make architectural decisions, and own the technical quality of everything we ship. You'll work directly with the founding team to solve hard problems: real-time driver matching, mapping in low-connectivity environments, mobile money payments, and scaling infrastructure across Central Africa's fastest-growing city.

Responsibilities

• Own and evolve Pronto's technology stack — Expo (React Native), Supabase, Google Maps, Mapbox, and Sentry
• Build features end-to-end across our rider and driver mobile apps and backend services
• Make key architectural decisions, including planning our eventual migration from Supabase to self-managed infrastructure
• Design and implement database schemas, Edge Functions, real-time subscriptions, and Row Level Security in Supabase
• Integrate and maintain mapping, geolocation, and routing systems (Google Maps, Mapbox)
• Optimize for real-world conditions in Kinshasa — intermittent connectivity, varied devices, and mobile money payment flows
• Set up and maintain monitoring, error tracking, and performance insights with Sentry
• Establish engineering best practices, CI/CD pipelines, and code review standards
• Leverage AI-assisted development tools to accelerate delivery and code quality

Requirements

• 6+ years of software engineering experience with a track record of owning complex systems
• Deep experience building mobile applications with React Native or Expo
• Strong backend skills — experience with PostgreSQL, database design, API development, and real-time systems
• Experience designing cloud infrastructure on AWS, GCP, or Azure
• Solid understanding of security fundamentals (authentication, authorization, data protection)
• Comfortable making architectural decisions with incomplete information in a fast-moving environment
• Proficiency with AI coding tools (GitHub Copilot, Claude, Cursor, or similar) as part of your daily workflow

Nice to Have

• Experience with Supabase (Auth, Realtime, Edge Functions, Row Level Security)
• Hands-on experience with containerization and orchestration (Docker, Kubernetes)
• Knowledge of CI/CD pipelines and infrastructure as code (Terraform, Pulumi)
• Experience with mobile money or alternative payment systems common in African markets
• Experience working in emerging markets or low-connectivity environments
• Background in mobility, logistics, or marketplace products
• French language skills
• Prior startup experience

Compensation & Benefits

• Competitive salary for the region
• Housing and meals provided in Kinshasa
• Relocation support (flights, visa assistance)
• Direct impact on product and company direction
