[Hiring] Senior Full Stack Developer @Sparix Global.

Role Description

As Senior Full Stack Developer, you will own both the frontend and backend of the platform — building the agent-builder experience users interact with, and the services behind it. You will turn a complex agent platform into an intuitive product where users can build, deploy, and run agents with ease.

Key Responsibilities

• Build the agent-builder interface — visual composition, configuration, testing, and monitoring of agents.
• Develop responsive, high-performance frontend applications with a clean, reusable component architecture.
• Design and build the backend APIs and services that power agent creation, deployment, and runtime.
• Implement real-time features — streaming agent outputs, live execution logs, and run traces.
• Integrate the frontend and backend with the AI / ML layer, third-party tools, connectors, and authentication providers.
• Own data models, API contracts, and end-to-end feature delivery from design through to production.
• Maintain quality through testing, code review, performance tuning, and sound engineering practices.

Qualifications

• 8–10 years of full-stack development experience, ideally on SaaS or developer / platform products.
• Hands-on experience with agent-builder / Agent OS platforms — products where users build, deploy, and run AI agents — and an understanding of the user-facing workflows these platforms require.
• Strong frontend expertise: React (or Next.js), TypeScript, modern state management, and component design.
• Solid backend experience: Node.js and / or Python, with REST and / or GraphQL API design.
• Experience with real-time technologies — WebSockets, SSE, and streaming UIs.
• Strong database skills across SQL and NoSQL (PostgreSQL, MongoDB, Redis, or similar).
• Experience with cloud deployment, CI/CD, containers (Docker), and Git-based workflows.
• Track record building complex, interactive UIs — workflow builders, dashboards, or no code / low-code tools.

Nice to Have

• Familiarity with visual workflow / node-based editor libraries (e.g. React Flow).
• Experience integrating LLM APIs and streaming responses into a user interface.
• Exposure to multi-tenant SaaS frontends and design systems.
