Mid-Level AI Engineer ( Backend Heavy )

About Devfum

At Devfum, we leverage cutting-edge technologies such as web development, artificial intelligence (AI), and extended reality (XR) to automate business processes, enhance customer experiences, and drive sustainable growth worldwide.We foster a collaborative environment where you’ll work on cutting-edge technology, contribute to impactful projects, and grow through continuous learning and career development.

Role Overview:Devfum is hiring a Mid-Level AI Engineer to design, build, deploy, and operate production-grade AI systems.This is not a research only role and not a pure backend role. It is a backend heavy AI engineering role focused on building real AI products end to end.

You will work on:

• AI system architecture
• LLM-powered automation and agent systems
• Custom model training and fine-tuning
• GPU-based deployment and inference optimization
• Production AI infrastructure and monitoring

1. Key Responsibilities

• Design AI solutions from problem definition to production
• Architect LLM-based systems (agents, tool-calling, workflows, RAG, hybrid approaches)
• Integrate third-party LLM APIs and custom models into backend services
• Train or fine-tune generative models when APIs are insufficient; replicate research into deployable pipelines
• Build and maintain AI inference + workflow APIs using FastAPI/Flask (async inference, background jobs, retries, rate limiting, error handling)
• Deploy and operate AI systems on GPU infrastructure (CUDA/NVIDIA), across single- and multi-GPU environments
• Optimize inference for cost, latency, throughput, memory usage, and reliability (batching, caching, CPU vs GPU tradeoffs)
• Apply model optimization techniques (FP16/INT8 quantization, ONNX, TensorRT, pruning, distillation) when needed
• Debug production issues (model failures, drift, quality degradation, latency regressions) and drive long-term stability
• Implement monitoring/observability for performance, drift, and output quality; trigger tuning/retraining when required
• Build CI/CD for AI services (model builds, deployments, versioning, rollbacks) and automate ops with Linux + Bash

2. Requirements

• Bachelor’s degree in Computer Science, Software Engineering, Data Science, AI/ML (or equivalent practical experience)
• 2–3 years of real AI/ML engineering experience
• Proven experience deploying AI/ML or LLM systems to production
• Hands-on experience with GPUs (CUDA/NVIDIA), and operating inference workloads on GPU servers
• Strong knowledge and hands-on experience building AI automation systems using LangChain and LangGraph.
• Strong Python backend engineering skills; experience building production APIs (FastAPI/Flask)
• Experience with Docker and CI/CD pipelines for deploying services/models
• Experience debugging live AI systems in production (failures, drift, latency, reliability issues)
• Familiarity with LLM systems: agents, tool calling, workflows, RAG, and evaluation approaches
• Familiarity with inference optimization concepts (batching, quantization FP16/INT8, ONNX/TensorRT)
• Ownership mindset: takes responsibility end-to-end and drives tasks to completion
• Calm under failure; handles incidents and ambiguity without panic
• Clear communicator (written + verbal), can explain tradeoffs and decisions
• Prioritizes reliability and measurable outcomes over hype and experimentation for its own sake
• Comfortable with responsibility and operating production systems on Linux environments
