About the role
Be part of an exciting journey to build next-generation, AI-native SaaS platforms for Supply Chain and Logistics, powered by cutting-edge technologies such as Agentic AI, Generative AI, Large Language Models (LLMs), and intelligent automation.
As a Full Stack Developer at Ralixar, you will join a dynamic founding engineering team, building innovative, scalable, and intelligent enterprise platforms end-to-end—from modern, intuitive React.js interfaces to robust Python-based backend services, APIs, and AI-powered capabilities. You will work closely with the Chief Architect, gain hands-on exposure to emerging AI technologies, take meaningful ownership of your solutions, and play a key role in shaping the technology, engineering culture, and future of a fast-growing AI-native company.
Responsibilities:
- Build responsive, accessible and well-tested web interfaces in React.js and TypeScript, from design tokens and component libraries through to complex, data-heavy workflow screens.
- Design, build and document REST APIs and implement back-end services in Python (FastAPI).
- Model and query data in PostgreSQL, keeping performance, data integrity and multi-tenancy in mind.
- Integrate with external systems (government trade portals, ERPs, carrier and tracking APIs) in a robust and auditable way.
- Build interfaces for human-in-the-loop decisions: showing AI-generated suggestions, confidence levels, and approval flows clearly to users.
- Write unit, integration and end-to-end tests; take part in code reviews; keep CI/CD pipelines healthy.
- Apply security and privacy by design, including India's DPDP Act requirements, role-based access and audit trails.
- Use AI coding assistants productively and responsibly as part of day-to-day development.
- Contribute to technical documentation, architecture decisions and sprint planning.
Requirements:
- Experience: at least 4 years of proven professional experience as a full-stack or front-end-heavy developer, with production applications you can talk about in depth.
- React.js : strong, current hands-on experience building production web applications in React.js (hooks, state management, routing, forms, performance tuning).
This is the required UI skill:
- JavaScript / TypeScript: solid command of modern JavaScript; TypeScript strongly preferred.
- APIs: experience consuming and building REST APIs and working with JSON-based contracts.
- Databases: working knowledge of a relational database, preferably PostgreSQL, and SQL.
- Engineering practice: Git, code reviews, automated testing and CI/CD.
- Python: production experience with Python 3. x, type hints and Pydantic.
- FastAPI or a similar Python web framework.
- PostgreSQL extensions: pgvector, TimescaleDB or PostGIS.
- Workflow and events: Temporal (durable workflows) and Kafka or another event-streaming platform.
- Agentic AI / LLM engineering: building with LLM APIs such as Claude, agent frameworks such as LangGraph or Pydantic AI, retrieval and structured outputs.
- Cloud: AWS, Docker, infrastructure-as-code.
- UI libraries: Mantine v7 or a similar component library; design-system work.
- Mobile: React Native with Expo.
- Location: currently based in Bengaluru (preferred) and able to work from our Bengaluru office (on-site).
- Communication: clear written and spoken English; comfortable working in a fast-moving, early-stage team.
