Job Title: Backend Engineer )
Location: Magodo Phase 1, Lagos
Work Type: Hybrid (Mondays, Wednesdays and Fridays)

About MarketEdge
MarketEdge is not just another CRM; it is the Customer Intelligence & Growth Platform for the African market. We are re-engineering the standard sales database into a high-speed, offline-first engine that helps SMEs—from QSRs to corporate service providers—find, know, and keep their customers.
We are building on top of the IDURAR Open-Source foundation (MERN Stack) and transforming it into a scalable, multi-tenant SaaS capable of handling millions of transactional and behavioral data points across the continent.
The Role
We are looking for a Mid to Senior Backend Engineer to join our hybrid work team and to own the architecture of our "Growth Engine." You will move beyond simple CRUD APIs to build complex Event-Driven Systems, Offline Sync Protocols, and High-Volume Marketing Queues.
You will work closely with the Solution Architect and the rest of the development team to ensure our platform is fast, resilient in low-bandwidth environments, and capable of delivering real-time Customer Intelligence (CI).
Key Responsibilities
- Core Architecture: Lead the migration of our Modular Monolith ) towards a structured, Service-Oriented architecture (NestJS/TypeScript) to support scale.
- High-Volume Queues: Design and implement robust background job processing using Redis & BullMQ to handle marketing blasts (SMS/WhatsApp/Email) without blocking the main API thread.
- Offline Synchronization: Build the "Sync Service" that handles data conflict resolution and delta updates between our MongoDB backend and the React Native (WatermelonDB) mobile app.
- Customer Intelligence Engine: Write complex MongoDB Aggregation pipelines to calculate real-time RFM (Recency, Frequency, Monetary) scores and Customer Health metrics.
- Integrations: Build secure, scalable integrations with third-party providers including Paystack/Flutterwave (Payments), Meta Graph API (Social), and Africa's Talking (SMS).
- API Design: Develop flexible GraphQL and REST endpoints that allow our frontend to fetch "Customer 360" data efficiently.
- Quality & Security: Enforce TypeScript strict typing, write comprehensive unit/integration tests (Jest), and ensure multi-tenant data isolation at the middleware level.
What We Are Looking For
Technical "Must Haves":
- 4+ years of backend engineering experience with .
- TypeScript Expert: You don't just use any; you understand generics, interfaces, and strict type safety.
- Database Mastery: Deep experience with MongoDB (Schema design, Indexing, and Aggregation pipelines). You know how to model data for performance.
- Message Queues: Proven experience with Redis (caching and queuing with BullMQ/Sidekiq equivalent).
- API Standards: Strong grasp of RESTful principles and GraphQL schema design.
- Experience with NestJS framework.
- Familiarity with the IDURAR open-source ERP platform.
- Experience building Offline-First applications (Sync protocols).
- Knowledge of Docker and Kubernetes (DevOps basics).
- Background in AdTech, CRM, or FinTech in the African context.
The Challenges You Will Solve
- The "Burst" Problem: How do we send 50,000 SMS notifications for a client's flash sale in 5 minutes without crashing the dashboard for everyone else?
- The "Offline" Problem: How do we sync 500 new "Quick Orders" from a field agent's tablet when they reconnect to a slow 3G network, ensuring no data is lost?
- The "Intelligence" Problem: How do we calculate a VIP Score for a customer in real-time based on their last 50 transactions across different branches?
Why Join MarketEdge?
- Build for Impact: You aren't just moving tickets; you are building the "Operating System" for African businesses.
- Technical Depth: You will work with complex problems like eventual consistency, event sourcing, and high-concurrency queues.
- Agile Culture: We value shipping code that works. We focus on "Definition of Done" that includes performance on slow networks, not just functionality on high-speed Wi-Fi.
