VP & Staff Software Engineer – Payments & Billing Platform

About the role

ShareShare is building Africa’s internet backbone and needs a senior individual contributor to own the most critical parts of its platform – payments, billing, and integration layers. You will work directly with the CTO and a small, high‑intensity engineering team to ship production systems that handle real financial transactions for ISP partners.

Key responsibilities

• Design, develop, and maintain the payments pipeline, including collections integration, revenue‑split engine, treasury operations, and payment‑completion handling.
• Own the billing engine covering subscription lifecycle, automated renewals, grace‑period enforcement, and plan‑change logic.
• Build and evolve the integration layer with partner BSS/OSS systems, including Splynx adapters and custom webhook delivery.
• Define service boundaries, event contracts (Kafka), data‑model evolution (Prisma/PostgreSQL), and API design for public and private endpoints.
• Lead migration from a legacy Next.js monolith to a NestJS micro‑services platform.

Required profile

• Senior‑level software engineer with a track record of delivering complex backend systems.
• Comfortable making architectural decisions and unblocking technical challenges.
• Experience working in a fast‑paced, product‑focused environment without direct people‑management responsibilities.

Required skills

• NestJS (TypeScript) and micro‑services architecture.
• PostgreSQL, Prisma ORM.
• Kafka for event‑driven communication.
• API design (REST/GraphQL) and integration with external payment providers (e.g., SasaPay, ChoiceBank).
• Experience with billing, subscription management, and payment processing workflows.

What we offer

• Opportunity to shape core infrastructure for a venture‑backed, high‑impact startup.
• Close collaboration with senior leadership and a small, talented engineering team.
• Competitive compensation and equity in a fast‑growing African tech company.
