Introduction
COSBYTE is seeking a highly skilled and passionate Full-Stack Engineer to join our core team and play a key role in building and scaling high-impact platforms that solve real problems for millions across Ghana and Africa.
You will focus on completing and scaling our soft-launched gig economy platform GigShip, while laying the technical foundation for an ecosystem that becomes an infrastructure backbone for multiple platforms.
What You'll Do
- Complete and scale GigShip: fix critical bugs from soft launch feedback, migrate from MongoDB to PostgreSQL + PostGIS, refactor to TypeScript, optimize performance (fast page loads and API responses), and drive user growth from waitlist conversions.
- Build and maintain full-stack features: backend APIs (Node.js + Express + TypeScript + Prisma), frontend UIs (React + Vite + TailwindCSS), and mobile app updates (React Native + Expo).
- Design and implement critical systems: geospatial queries (PostGIS for nearby features), real-time capabilities (Socket.io), payments (Paystack, Flutterwave, mobile money), SMS (Africa's Talking), and media storage (Cloudinary).
- Extract and build reusable infrastructure: refactor code into shared packages (e.g., auth, wallet, geo-engine), set up monorepo architecture (pnpm workspaces + Turbo), and establish unified systems to support future scalability.
- Write clean, tested code using Jest, Playwright, and best practices; ensure performance, security, and maintainability.
- Deploy and monitor applications (Railway/Render, Sentry) while making pragmatic technical decisions in a fast-paced environment.
- Collaborate closely with the founder on product priorities, implement user feedback, support growth initiatives, and help recruit additional engineers.
Our Tech Stack
You must have strong production experience with most of the following:
Backend
Frontend & Mobile
Infrastructure & Tools
Nice to Have
If you lack experience with 80%+ of this stack or are fully engaged in another role, this role is not a fit — we need someone who can contribute immediately at full speed.
What We're Looking For
- Proven Expertise: 3–5+ years full-stack development with shipped production web and/or mobile apps you can point to. Bonus: products with real users in Africa.
- Strong Technical Foundation: Expert-level Node.js + TypeScript + React (and React Native comfort); PostgreSQL schema design, migrations, and optimization.
- Startup Mindset: Ships fast, iterates quickly, thrives in ambiguity, debugs across the full stack, makes pragmatic tradeoffs (MVP > perfect), resourceful, and takes full ownership.
- Impact-Driven & Mission-Aligned: Passionate about building meaningful solutions for Ghana/Africa and motivated by significant equity in an early-stage company.
- AI-Fluent (Strong Plus): Leverages AI tools to accelerate development 2–3x while understanding and refining generated code.
- Location Flexibility: Based in Accra or willing to join hybrid rhythm (in-person collaboration in Accra/Kasoa).
What We Offer
Meaningful Equity Stake
Significant ownership in Cosbyte with standard vesting schedule and cliff — real ownership in what you build.
Early-Stage Cash Stipend
Monthly cash stipend to cover basic needs for the first few months as we scale toward profitability and fundraising.
