Overview:

We're looking for a Full Stack Developer with strong backend expertise who can build,

manage, and scale AI-driven products end to end. You'll play a critical role in designing

scalable architectures, optimizing performance and cost, and building robust AI and agentic

systems.

Responsibilities

1. Architect and build scalable backend systems using FastAPI, PostgreSQL, and Redis.

2. Design, develop, and maintain AI-driven applications, integrating multiple LLMs, APIs,

and agentic frameworks.

3. Implement vector databases (pgvector, Qdrant, etc.) for RAG and AI memory systems.

4. Orchestrate multi-agent AI systems with LangChain/LangGraph, including function

calling, agent collaboration, and monitoring.

5. Build and integrate RESTful APIs for frontend and external use.

6. Manage DevOps workflows, including CI/CD, cloud deployments (AWS/GCP), server

scaling, and logging/monitoring (Sentry).

7. Optimize application cost, latency, and reliability, balancing speed with LLM call

efficiency and caching strategies.

8. Collaborate with product, design, and AI teams to translate business requirements into

high-performing tech.

9. Maintain documentation and ensure code quality with tests, reviews, and async-first

architecture.

10. Contribute to frontend development (React + TypeScript) when necessary, ensuring

seamless API integration and data visualization.

Requirements

Core Skills

• Strong proficiency in Python and FastAPI.

• Experience with PostgreSQL (including pgvector) and SQLAlchemy (async).

• Solid understanding of Redis, RQ (Redis Queue), and caching mechanisms.

• Proven experience integrating LLMs and AI APIs (OpenAI, Anthropic, etc.).

• Hands-on experience with LangChain / LangGraph, RAG pipelines, and agent

orchestration.

• Experience working with cloud platforms (AWS / GCP) and managing file storage (S3).

• Familiarity with frontend stacks (React, TypeScript, Tailwind, Zustand).

• Working knowledge of DevOps: Docker, CI/CD pipelines, deployment automation, and

observability tools (Sentry, Mixpanel, Clarity).

Bonus / Nice to Have

• Experience building agent monitoring dashboards or AI workflows.

• Prior experience in startup or product-based environments.

• Understanding of LLM cost optimization, token management, and function calling

orchestration.

• Familiarity with external API integrations like BrightData, Hunter.io, Adzuna, and Serper.

• Experience building scalable AI products (e.g., chatbots, AI copilots, data agents, or

automation tools).

Mindset

• Startup-ready: comfortable working in fast-paced, ambiguous environments.

• Deep curiosity about AI systems and automation.

• Strong sense of ownership and accountability for shipped products.

• Pragmatic and cost-conscious in architectural decisions.

• Excellent communication and documentation skills.

Note: Apply only if you have worked minimum of 2 years  in your current organisation 

Basic Qualifications

• Bachelor’s degree in Engineering with specialization in Computer science or related field
• 5+ years of experience as a software engineer in a product development setting
• Love of technology and experience with one or more programming languages from Java, Python, or Go
• Experience in full-stack development including designing APIs and integration patterns, implementing security, implementing frameworks for Unit and End-to-End testing
• Experience with micro-services architecture

Preferred Qualifications

• Good communication skills. You can communicate well in the English language with product managers, your team members, and external stakeholders, to understand their needs and convey yours, in a clear, precise manner - verbally, or in writing. 
• Strong collaboration skills. You have demonstrated the ability to work with both - senior & junior technical professionals and get work done. You quickly earn the trust of the people you work with. People enjoy and have fun working with you.
• Deadline oriented. You understand that deadlines are meant to be met. Challenges will surface, and obstacles and roadblocks will cause delays, but you plan for them in advance and still ship your features on time to meet your commitments.
