South Africa: Fullstack Developer

Planet is seeking a seasoned and dynamic Full Stack Developer to lead and contribute to the design, development, and deployment of scalable, secure, and performant software systems. The ideal candidate will demonstrate technical leadership while remaining hands-on with the codebase, ensuring best practices are followed across the front-end, back-end, and infrastructure. This role will also serve as a critical bridge between technical execution and business objectives. Flutter App & Web Development Build and maintain Flutter codebases for iOS, Android, and Web with clean, scalable architecture. Translate UX/UI designs into polished, responsive experiences (custom widgets, animations, adaptive layouts). Implement and maintain state management using our preferred patterns (e.g., Riverpod/BLoC), aligned to a modular architecture. Ensure strong performance across devices (rendering, frame pacing, memory, startup time, build size). Implement robust routing/navigation and deep linking (e.g., GoRouter patterns where relevant). Build telemetry into flows (events, funnels, feature usage) to support product decision-making. Backend Engineering (Python, FastAPI-first) Build and maintain Python backend services using FastAPI (and collaborate with existing services where Django/Flask may exist). Design and implement secure, well-documented REST APIs (GraphQL exposure is a plus where needed). Implement authentication/authorization patterns suitable for consumer apps (JWT/OAuth2, role-based access where relevant). Integrate third-party services (payments, messaging, CRM/marketing tools, analytics, webhooks). Own reliability basics: background jobs where required, retries, idempotency, rate limiting, and graceful failure. Data & Database Collaboration (PostgreSQL) Work with engineering/data stakeholders to design and evolve schemas, indexes, and queries. Build performant data access patterns and support reporting/ops use cases without degrading core workloads. Apply practical data integrity practices (constraints, migrations, auditing where required). Integrations & Platform Thinking Build, consume, and maintain integrations via APIs and webhooks, ensuring secure and observable data flow. Support real-time or near-real-time features when required (WebSockets or async patterns). Contribute to modular service boundaries and clean interface contracts. Delivery, DevOps, and Quality Contribute to CI/CD pipelines and release hygiene (builds, environments, feature flags where relevant). Write and maintain tests across the stack: unit, widget, integration, and API tests. Participate in code reviews, architecture discussions, sprint planning, and continuous improvement. Produce clear documentation for handover, onboarding, and operational support. . Experience and Exposure The following minimum experience and exposure is needed for this role: Bachelors or Masters degree in Computer Science, IT or related field. 5 years of software development experience, with 2 years in a technical leadership role. Proven full‑stack expertise: Flutter (mobile/web), Java (Spring or equivalent), PHP frameworks, and SQL database design. Expert in CI/CD and DevOps practices (Docker, Kubernetes, AWS/GCP/Azure). Strong track record of hands‑on delivery of secure, scalable systems in Agile environments. Excellent communication, people management and stakeholder‑engagement skills. Education Degree or Diploma in Information Technology (Programming focus) Grade 12
