REMOTE; India): AI Engineer- SaaS Platform

AI Engineer

We are looking for an AI Engineer to maintain and enhance the AI-driven backbone of the Sootra platform. This role involves ensuring production stability of LLM/VLM pipelines, optimizing model interactions, maintaining APIs and queues, and building feedback loops that continuously improve AI outputs.

Responsibilities

• Maintain and optimize LLM- and VLM-powered services for content generation, compliance scoring, and campaign testing.
• Manage and scale Flask/FastAPI microservices, ensuring high uptime and low latency.
• Maintain Dramatiq queues for async AI workflows, campaign generation, and pipeline orchestration.
• Deploy, monitor, and debug Uvicorn/Gunicorn-based hosting in production environments.
• Integrate with Open Router and equivalent LLM routing tools to balance cost, latency, and quality.
• Design and refine prompt engineering strategies for reliability, context-awareness, and compliance.
• Build and maintain feedback pipelines for AI model evaluation (human-in-the-loop scoring, automated quality checks, reinforcement).
• Expose and maintain REST APIs for AI services, ensuring secure, versioned endpoints.
• Collaborate with backend/frontend teams to keep microservice architecture aligned and maintainable.
• Track token consumption, latency, and error rates to ensure production-grade performance.

Required Skills

• Programming:
  Strong in Python, with experience in production-grade codebases.
• Frameworks:
  Flask (for APIs), FastAPI (optional), Uvicorn/Gunicorn for async hosting.
• Queues/Workers:
  Dramatiq (or Celery/RQ equivalent) for background jobs.
• AI/ML:
  Hands-on with LLMs and VLMs, including prompt engineering, fine-tuning, and evaluation.
• AI Infrastructure:
  Familiar with Open Router or equivalent LLM/VLM routing & fallback tools.
• Architecture:
  Experience designing and maintaining microservice architectures.
• APIs:
  Strong experience with REST API design (auth, rate limiting, documentation).
• Production:
  Dockerized deployments, CI/CD pipelines, logging/monitoring, error handling.
• Feedback Loops:
  Building structured evaluation/feedback systems for AI model performance.
• Cloud: AWS/GCP experience preferred (deployment, monitoring, scaling).

Experience

• 3–5 years as an AI Engineer or Python Backend Engineer working with production systems.
• Prior work with SaaS platforms, LLM/VLM integrations, or AI-first products is highly valued.

Demonstrated ability to maintain AI pipelines in production, not just prototypes.
