This role centers on advanced distributed systems engineering with a focus on Generative AI (GenAI), Large Language Models (LLMs), Retrieval-Augmented Generation (RAG) pipelines, and Model Context Protocol (MCP). The ideal candidate will bring hands-on experience building ETL pipelines, implementing serverless solutions, and integrating scalable backends using PostgreSQL, MongoDB, RabbitMQ, and Kafka. You will work across AI, data, and platform engineering teams to support intelligent automation and robust cloud infrastructure.

Key Responsibilities:

  • Integrate and maintain distributed messaging systems using RabbitMQ, Apache Kafka, and Redis to support asynchronous task execution.
  • Build and maintain RAG pipelines in support of LLM-powered applications, leveraging vector search and retrieval strategies.
  • Support Generative AI use cases by developing APIs for LLM orchestration, prompt engineering, and system integration.
  • Deploy and manage cloud infrastructure on AWS, including Lambda, EC2, VPC, S3, and CloudWatch.
  • Implement and optimize data storage and caching layers using PostgreSQL and MongoDB.
  • Contribute to MCP architecture design and system resilience improvements for mission-critical workloads.
  • Collaborate on Salesforce integration tasks—syncing data, automating workflows, and building REST connectors.
  • Apply DevOps best practices: configure CI/CD pipelines using GitHub Actions, containerize services with Docker, and enforce automated test coverage.
  • Participate in Agile ceremonies, conduct peer code reviews, and document system architecture and deployment guides.
Requirements:
  • Master's degree in Computer Science, Data Science, or a related field.
  • 5+ years of professional experience in backend development, distributed systems, or cloud engineering.
  • Proven experience with Generative AI, RAG, and LLM model integration in production settings.
  • Hands-on development with RabbitMQ, Kafka, Redis, and messaging queues for decoupled system design.
  • Deep knowledge of ETL development, data processing, and data modeling across PostgreSQL and MongoDB.
  • Proficient in cloud deployment and infrastructure (AWS: EC2, Lambda, S3, IAM, VPC).
  • Familiar with Salesforce CRM concepts, API integration, and automation scripting.
  • Strong understanding of containerization, CI/CD pipelines, and secure development practices.
  • Excellent communication, documentation, and cross-team collaboration skills.
Preferred Qualifications:
  • Salesforce Certification (Administrator or Developer)
  • Experience in motion-tracking, health tech, or annotation tooling platforms
  • Familiarity with Firebase (Auth, Firestore, Cloud Functions) and PostHog for analytics
  • Prior experience with Looker Studio, Power BI, or visualization tools
What We Offer:
  • Competitive compensation based on experience and skill set
