About the Role
We're looking for a Mid-Level Backend Developer to join our engineering team, working on backend systems that handle large-scale data and power AI agentic workflows. You'll design, build, and maintain server-side systems, APIs, and data pipelines, working closely with frontend, product, and DevOps teams to ship reliable, scalable software.

Responsibilities
Design, develop, and maintain backend services and RESTful/GraphQL APIs
Build and manage systems that process, store, and query large-scale datasets efficiently
Build and orchestrate AI agentic workflows — tool use, multi-step reasoning chains, agent-to-agent communication, and autonomous task execution
Integrate LLM APIs (e.g., Anthropic Claude, OpenAI) into production backend systems
Design, optimize, and maintain database schemas across PostgreSQL and MongoDB
Implement and optimize search/indexing solutions, ideally using OpenSearch
Write clean, well-tested, maintainable Python code using modern frameworks
Optimize applications and data pipelines for performance, scalability, and reliability




Collaborate with frontend engineers to integrate user-facing elements with server-side and agent logic
Participate in code reviews and contribute to engineering best practices
Debug and resolve production issues, including data pipeline failures and agent behavior edge cases
Contribute to architecture and technical design discussions around data systems and agent orchestration
Requirements
5-6 years of qualified backend development experience
Strong proficiency in Python, with hands-on experience in frameworks such as FastAPI, Django, or Flask
Must have: solid working knowledge of PostgreSQL and MongoDB — schema design, indexing, query optimization, and performance tuning
Demonstrated experience working with large-scale data — high-volume datasets, high-throughput systems, or data-intensive applications
Practical experience building or integrating AI agentic systems (e.g., LangChain, LangGraph, LlamaIndex
