Job Description
About the Role
We are building a next-generation AI-native platform and are looking for an experienced backend engineer to help architect and build the core systems that power intelligent commerce, workflow automation, fulfilment, payments, and operational decision-making.
This is not a traditional ecommerce role. You will be working on complex backend systems that combine commerce infrastructure, workflow orchestration, AI-assisted automation, and large-scale operational processes.
What you'll be building
• Backend services in TypeScript and Node.js.
• Commerce systems on Medusa v2, anchored to an ERP that stays the source of truth — Medusa projects catalogue and writes orders back, never the other way around. (Respecting that boundary is central to how we keep money and data correct.)
• Workflow and orchestration systems for checkout, payments, compliance, and fulfilment.
• AI-assisted operational and customer-facing workflows.
• Event-driven services, platform APIs, and the integrations that connect commerce, payments, and logistics.
• Scalable systems supporting international commerce operations.
Required skills
Backend engineering
• 5+ years backend engineering experience — production systems, not just features.
• Strong TypeScript and Node.js.
• PostgreSQL and relational database design; Redis or similar.
• REST APIs, webhooks, queues, and asynchronous processing.
• Distributed systems and scalable architecture.
Medusa v2 — a firm requirement
• Real production experience with Medusa v2 specifically. We rely on Medusa v2's workflow engine, validate hooks, payment module, and region/currency abstraction — this isn't a build you can pick up from Medusa v1 or generic headless-commerce experience alone.
• Custom workflows and module development; checkout, order, payment, and fulfilment flows.
• Comfortable integrating Medusa with an external ERP system of record.
Workflow & systems design
• Workflow orchestration, state management, and event-driven architecture.
• Idempotency, retries, and failure recovery.
• Background jobs and queue-based processing.
• Experience with Temporal, BullMQ, Kafka, EventBridge, Cadence, or similar is highly desirable.
AI & automation
• Experience with one or more of: LangGraph, LangChain, RAG, vector databases, agentic workflows, or production LLM applications.
Experience we value highly
Headless commerce · marketplaces · OMS · inventory · payments infrastructure · logistics and fulfilment · ERP integrations · cross-border or compliance-heavy platforms.
Leadership & working style
We're looking for someone who:
• Thinks from first principles and designs systems from concept to production.
• Makes architectural decisions confidently and documents them clearly.
• Cares about building things that are accurate and defensible, not just demo-ready.
• Enjoys hard engineering problems and is comfortable in a startup with real ownership.
• Wants to grow into an engineering leadership role.
Nice to have
Next.js · Python · ERPNext / Frappe · Stripe integrations · AWS / GCP · open-source contributions · startup experience · experience mentoring or leading engineers.
Why join us
• A genuinely challenging AI-native commerce platform to build from the ground up.
• Founding-level ownership and technical influence.
• Direct access to the founder and to decision-making.
• A clear path into engineering leadership.
• Salary plus equity — you share in what you build.
To apply
Send your CV, LinkedIn, and GitHub (if available), and a short answer to one question — it tells us more than a long CV:
Pay: ₦700,000.00 - ₦1,000,000.00 per month
Application Question(s):
• Describe a production system you built that required retries, failure recovery, workflow orchestration, or transaction management. What were the biggest challenges and how did you solve them?
• Send your GitHub
Experience:
• backend engineering experience.: 5 years (Preferred)
• Production experience with Medusa v2.: 3 years (Preferred)
