PHTN.ai is building next-generation intelligent systems powered by AI and automation and is looking for a Python Developer to architect scalable frameworks, APIs, and integrations while enabling AI-driven agents to perform complex workflows securely and efficiently.
Requirements
- Strong proficiency in Python (3.x), with focus on OOP and modular design.
- Proven experience in building frameworks, libraries, or SDKs (not just applications).
- Expertise in design patterns, dependency injection, and plugin-based architectures.
- Experience with FastAPI, Flask, Django or similar web frameworks.
- Solid understanding of APIs (REST, GraphQL) and API gateway integration.
- Knowledge of async programming (asyncio, aiohttp).
- Proficiency in testing frameworks (PyTest, unittest) and CI/CD workflows.
Responsibilities
- Design, develop, and maintain Python frameworks that provide reusable components and structure for applications.
- Architect modular, scalable, and extensible frameworks for APIs, data processing, or AI integrations.
- Implement best practices in software engineering: OOP, design patterns, modular architecture.
- Develop APIs and SDKs for framework adoption across teams.
- Collaborate with AI engineers to integrate Agentic AI systems (e.g., AI agents, LLM orchestration frameworks like LangChain, LlamaIndex, Google ADK).
- Ensure security, reliability, and observability of framework components.
- Write unit/integration tests and maintain CI/CD pipelines.
Other
- 3 to 4 Years experience
- A framework builder mindset – you enjoy designing systems other developers will use.
- Passionate about AI and automation, eager to experiment with agent-driven architectures.
- Participate in code reviews, mentor junior developers, and contribute to technical design discussions.
- Document frameworks, APIs, and libraries for developer adoption.
