Job Summary

Priority for Python Rest API Development and Familiarity with Security Tooling (Dev Sec Ops )

  • Strong REST API development skills (Python / Go / Node.js) — no “architecture-only” profiles

  • Need hands-on profiles

  • Experience with AI-assisted development (Copilot, GPT, internal AI tools, etc.)

  • Familiarity with security tooling (CVE, vulnerability scanners, container images)

  • Experience with APIs, automation pipelines, and data aggregation tools

  • Ability to build end-to-end tools quickly using AI (UI + backend + integrations)

  • Comfortable working in fast-paced, ambiguous, delivery projects

  • Knowledge on AWS and automation of lambda services

This role is accountable for delivering advanced Generative AI solutions by leveraging large language models and prompt engineering techniques. The position drives technical excellence in project execution, ensures robust solution design, and optimizes AI-driven applications using modern Python frameworks and scalable database technologies. The individual acts as a technical authority, guiding teams in implementing best practices, and plays a key role in the successful delivery of complex AI projects aligned with organizational goals.

Key Responsibilities

1. Provide advanced proficiency in GenAI and prompt engineering by designing, refining, and deploying LLM-driven solutions using Python frameworks such as Flask, Django, and FastAPI.
2. Architect and implement RESTful APIs to integrate LLM models and vector databases (e.g., Pinecone, PostgreSQL, AzureAISearch) for scalable and efficient data retrieval in AI applications.
3. Optimize database schemas and embeddings using PostgreSQL and VectorDB to enhance performance and accuracy of generative AI systems.
4. Oversee code quality and performance by conducting comprehensive code reviews and enforcing best practices in Python, RESTful API development, and prompt engineering.
5. Lead technical feasibility studies and solution breakdowns, evaluating architecture alternatives and technical risks for GenAI project modules.
6. Collaborate with internal stakeholders to define technical objectives, deliverables, and ensure process compliance in the development and deployment of AI-powered solutions.

Skill Requirements

1. Advanced Proficiency In Genai, Large Language Models (Llms), And Prompt Engineering.
2. Solid Expertise In Python Programming, Including Frameworks Such As Flask, Django, And Fastapi.
3. Indepth Knowledge Of Restful Api Design And Implementation For Ai Integrations.
4. Advanced Skills In Database Management Using Postgresql, Mysql, And Vectordb Technologies (E.G., Pinecone, Azureaisearch).
5. Strong Understanding Of Embedding Techniques And Their Application In Generative Ai Workflows.
6. Experience In Optimizing Code Quality, Performance, And Scalability Of Aidriven Applications.

Other Requirements
