Ruby on Rails Developer Job Giga Cypher Systems
Job description & requirements
IT Jobs. Giga Cypher Systems Jobs
We’re building a last-mile delivery platform — an operationally complex, event-driven system that real businesses depend on. We’re looking for a mid-level Rails developer who can confidently build, refactor, and extend production code in a fast-moving, collaborative team.
What you’ll do
- Build and extend core features of an event-driven Rails platform: parcel management, manifests, notifications, reporting.
- Write clean, modular, domain-driven code built for long-term scalability.
- Build internal tools and dashboards with Rails, Hotwire, and Tailwind CSS.
- Design and maintain integrations with third-party services (M-Pesa, payment gateways, SMS/WhatsApp providers).
- Work with background jobs, queues, and real-time updates as everyday tools, not afterthoughts.
- Collaborate with senior developers on architecture, code reviews, testing, and deployments.
What we’re looking for
- 2–3 years building real applications with Ruby on Rails.
- Solid grasp of Rails MVC, RESTful and API-mode design, service objects, and background job processing (Sidekiq or similar).
- Strong PostgreSQL fundamentals — relationships, query optimization, and a willingness to learn its more advanced corners.
- Comfort integrating third-party APIs: payments, messaging, webhooks.
- Fluency with Tailwind CSS or a similar utility-first framework.
- A debugging, refactoring instinct and the discipline to write maintainable, well-structured code.
- Clear communication and the ability to work independently when needed.
Nice to have
- Experience with multi-tenant architecture, event-driven systems, or geospatial/location data.
- Familiarity with Hotwire (Turbo/Stimulus) or real-time features (WebSockets/ActionCable).
What we offer
- KSh 40,000 – 45,000/month, based on skills and experience.
- Unrivalved experience in a multi-tenant, event-driven, and scalable architecture.
- A flexible, supportive, learning-oriented environment with a clear growth path.
