Sr Backend Python + GEN AI

About the Role

Senior Back-End Engineer

Key Responsibilities

• Architect, develop, and maintain scalable back-end services and APIs for SAAS products.
• Integrate AI/ML models and APIs—including Claude (Anthropic), OpenAI, Hugging Face, and custom models—into production systems.
• Ensure secure-by-design architecture: implement best practices in authentication, authorization, encryption, and data privacy.
• Optimize application performance, reliability, and scalability on cloud platforms (AWS, Azure, GCP).
• Collaborate with front-end engineers to ensure seamless end-to-end delivery; make minor UI changes as needed.
• AI Agent Development: Design, build, and deploy intelligent agents using frameworks like CrewAI and AutoGen to automate complex tasks and workflows.
• LLM Integration: Work with leading LLMs, applying expertise in prompt engineering and context engineering to fine-tune model behavior and performance.
• API Development: Develop and maintain robust, scalable RESTful APIs using Node.js to serve our AI applications.
• Backend Systems: Build and optimize backend services using Python to support our core AI logic and data processing pipelines.
• Implement CI/CD pipelines, automated testing, and monitoring for robust deployments.
• Participate in code reviews, mentor junior engineers, and contribute to technical decision-making.
• Document architecture, APIs, and workflows for internal teams.

Core Skills & Qualifications

• 6–9 years of hands-on back-end development experience (Python strongly preferred; Node.js/Java also considered).
• Proven experience designing and building RESTful and GraphQL APIs.

• Direct experience integrating AI/ML models and APIs, including Claude (Anthropic), OpenAI, and Hugging Face, into production systems.

• Strong knowledge of relational (PostgreSQL, MySQL) and/or NoSQL (MongoDB, DynamoDB) databases.
• Proficient with cloud platforms (AWS, Azure, or GCP) and containerization (Docker; Kubernetes a plus).
• Familiarity with CI/CD tools (Jenkins, GitHub Actions, GitLab CI, etc.).
• Exposure to front-end frameworks (React, Angular, or Vue) and ability to make minor UI changes.
• Strong understanding of secure coding, data privacy, and compliance.
• Experience with Git-based workflows and collaborative development.
• Experience working on advanced architectural patterns such as MCP, A2A would be added advantage.
