About GreenBay
GreenBay is on a mission to make appliance ownership affordable and sustainable by creating Africa's leading platform for trade-in, refurbishment, and resale. We're tackling a massive market gap while unlocking circular economy jobs and climate-positive impact. Backed by Delta40 and international partners, we're scaling fast across East Africa.

The Role
We are seeking a Co-Founder & CTO to join our leadership team. This is a career-defining opportunity to set GreenBay's technical vision, build scalable systems, and lead our engineering team from zero to one and beyond.

The CTO will be full-stack: able to architect, code, and deploy while also recruiting and mentoring a growing tech team. From trade-in AI to payments to multi-channel marketplace integrations, this role spans backend, frontend, and AI.

What you'll do

  • Define & own GreenBay's technical strategy and architecture.
  • Build and scale full-stack systems: backend services, frontend interfaces, and APIs connecting WhatsApp, Shopify, payments, and logistics.
  • Lead AI-powered product development (valuation models, workflow automation, predictive diagnostics).
  • Recruit, manage, and mentor a growing engineering and product team.
  • Ensure the scalability, reliability, and security of GreenBay's systems.
  • Play a key role in fundraising, partnerships, and strategic leadership.

What we're looking for

  • 7+ years of full-stack engineering and product development experience.
  • Strong command of backend (Python/Node, PostgreSQL, cloud) and frontend (React, mobile/web).
  • Proven track record of shipping and scaling platforms (marketplaces, e-commerce, or logistics).
  • Familiarity with AI/ML (LLMs, computer vision, pricing engines).
  • Entrepreneurial mindset—hands-on builder ready for speed and ambiguity.
  • Broad-based business skillset, including ability to think strategically, own and manage a budget, and contribute to commercial success

Why join us

  • Shape the technical DNA of a fast-scaling African venture.
  • Build systems at the intersection of e-commerce, AI, and the circular economy.
  • Work with a seasoned founding team (ex-Jumia, Wasoko, MarketForce).
  • Base salary + meaningful equity.

Location: Nairobi strongly preferred; remote possible with regional engagement
Commitment: Full-time, long-term
Compensation: Base salary + equity stake
