Job Description

Devsinc is hiring a skilled AI/ML Engineer with 2 to 3 years of professional experience in building and fine-tuning Generative AI models (LLMs, Diffusion Models), Vision-Language Models (VLMs), and both classical and deep learning systems, developing solutions from scratch and taking them end-to-end into production.

This role combines modeling and MLOps expertise, involving end-to-end ownership from model training and fine-tuning to optimization, deployment, and serving You’ll work on diverse, high-impact projects such as Generative AI applications, Stable Diffusion, OCR, theft detection, and recommendation systems , designing, optimizing, and serving custom models for real-world production use.

Key Responsibilities:

• Develop production inference stacks Convert and optimize models (Torch → ONNX → TensorRT), quantize/prune, profile FLOPs and latency, and deliver low-latency GPU inference with minimal accuracy loss.
• Build robust model-serving infrastructure Implement FastAPI/gRPC inference services, token or frame-level streaming, model versioning and routing, autoscaling, rollbacks, and A/B testing.
• Create Computer Vision solutions from scratch Design pipelines for object detection, theft detection, OCR (document parsing, structured extraction), and surveillance analytics; fine-tune Hugging Face pretrained models when beneficial.
• Fine-tune Stable Diffusion and other generative models for brand- or style-consistent image generation and downstream vision tasks.
• Train and fine-tune Vision-Language Models (VLMs) for multimodal tasks (captioning, VQA, multimodal retrieval) using both from-scratch and transfer-learning approaches.
• Design and adapt LLM-based Generative AI systems for conversational agents, summarization, RAG pipelines, and domain-specific fine-tuning.
• Implement MLOps / LLMops / AIOps practices Automate CI/CD for training and deployment, manage datasets and experiments, maintain model registries, and monitor latency, drift, and performance with alerting and retraining pipelines.
• Develop data acquisition & ingestion pipelines Build compliant scrapers, collectors, and scalable ingestion systems with proxy rotation and rate-limit handling.
• Integrate third-party models and APIs (Hugging Face, OpenAI, etc.) and design hybrid inference strategies combining local and cloud models for optimal performance.

Requirements

• Education Bachelor’s or Master’s degree in Computer Science, Artificial Intelligence, or related field.
• Experience 2 to 3 years of professional experience in AI/ML or relevant domains, with a proven track record of developing, training, and deploying machine learning or deep learning models in real-world environments.
• Strong expertise in Computer Vision object detection, segmentation, OCR pipelines (training from scratch and transfer learning).
• Deep understanding of model optimization quantization, pruning, distillation, FLOPs analysis, CUDA profiling, mixed precision, and inference performance trade-offs.
• Proven ability to design and train models from scratch, including architecture design, loss functions, training loops, and evaluation.
• Hands-on experience with LLMs and diffusion-based models (e.g., Stable Diffusion).
• Proficiency with ONNX, TensorRT, TorchScript, and serving frameworks (Triton, TorchServe, or ONNX Runtime).
• Skilled in GPU programming and CUDA optimization (profiling with nvprof/nsight, memory management, multi-GPU setups).
• Strong backend engineering in Python (FastAPI, Flask), async programming, WebSockets/SSE, and RESTful API design.
• Experience with containerization and orchestration (Docker, Kubernetes, Helm) and deploying GPU workloads to AWS/GCP/Azure or on-prem clusters.
• Understanding of classical ML techniques (regression, classification, clustering) and experiment design.
• Solid software engineering discipline CI/CD, testing, code reviews, reproducibility, and version control.
• Nice-to-Have: Familiarity with privacy-preserving ML (differential privacy, federated learning) and observability tools like Prometheus, Grafana, Sentry, or OpenTelemetry.
• Collaborative – open to knowledge-sharing and teamwork.
• Team Player – willing to support peers and contribute to collective success.
• Growth Minded – eager to learn, improve, and adapt to emerging technologies.
• Adaptable – flexible in dynamic, fast-paced environments.
• Customer-Centric – focused on delivering solutions that create real business value.
