Description :

FlexAI is looking for a FullStack Engineer who can build end-to-end features across our PaaS platform, including frontend UI layers, backend APIs, data models, and integrations with compute and infrastructure systems. You will work on modules such as Squirrel (end user dashboard), Marketplace, and Licensing, shaping the full spectrum of the user experience and backend logic.

Responsibilities :

- Build full-stack features across Squirrel, Marketplace, and Licensing, owning both frontend and backend components.

- Develop frontend modules using React, Vite, Bun, Chakra UI, react-query, and React-Table.

- Implement backend logic, APIs, and data models using Python, FastAPI, Pydantic, and sqlmodel.

- Design clean API contracts between frontend and backend components with a focus on performance and clarity.

- Build robust data flows across multi-architecture compute workflows, including job management, orchestration views, and resource interactions.

- Collaborate with SRE, runtime, and platform teams to ensure backend services integrate smoothly within FlexAI's PaaS.

- Troubleshoot issues across the full stack from UI inconsistencies to backend failures.

- Participate in architectural and design discussions for both client and server components.

- Ensure production readiness, reliability, and scalability of features.

Requirements :

- Strong hands-on development experience with Python + golang (true Python fullstack capability).

- Experience with FastAPI, pydantic, sqlmodel, and modern async backend development.

- Deep understanding of vite, bun, and frontend build/performance optimisation.

- Ability to manage frontend async workflows using react-query and complex data tables using React Table.

- Strong API design skills and comfort working across schemas, data models, and serialisation layers.

- Experience building modular services and UI-driven systems with high data throughput.

- Ability to operate independently in a high-speed environment and take full ownership of features.

- Strong communication and cross-functional collaboration skills.

- Experience working with cloud APIs, compute runtimes, schedulers, or developer tooling.

- Knowledge of SRE concepts (Kubernetes, CI/CD, observability).

- Familiarity with licensing workflows or enterprise cloud marketplaces.
