Note: The job is a remote job and is open to candidates in USA. Bright Vision Technologies is a forward-thinking software development company dedicated to building innovative solutions that help businesses automate and optimize their operations. We are seeking an AI Performance Optimization Engineer to focus on optimizing AI training and inference workloads, requiring expertise in GPU architecture and model optimization techniques. The role involves collaboration with cross-functional teams to deliver well-engineered solutions and improve production performance.

Responsibilities

• Profile and optimize end-to-end AI training and inference pipelines for throughput, latency, and cost
• Identify and eliminate bottlenecks across data loading, model compute, communication, and memory
• Implement and tune quantization, sparsity, and pruning strategies to reduce model footprint and accelerate inference
• Optimize distributed training using tensor parallelism, pipeline parallelism, FSDP, and ZeRO-style sharding
• Tune attention implementations using Flash Attention, paged attention, and related techniques
• Implement KV cache optimization, continuous batching, and speculative decoding for LLM serving
• Drive compiler-level optimizations using Triton, XLA, Torch Inductor, or TVM, working with the broader ML framework community to land improvements that translate into measurable end-to-end performance gains
• Optimize data pipelines, sharding strategies, and storage access patterns for high-throughput training
• Build and maintain rigorous benchmark suites and regression frameworks across workloads
• Collaborate with ML and platform engineering teams to embed best practices in standard pipelines
• Drive cost-efficiency improvements through model architecture, hardware selection, and scheduling strategies
• Evaluate new hardware and software offerings and advise on adoption
• Document performance tuning playbooks and share findings broadly across engineering teams
• Stay current with AI systems to research and translate advances into production improvements

Skills

• Bachelor's or master's degree in computer science, Computer Engineering, or related field
• Six or more years of experience in performance engineering, ML systems, or HPC
• Strong proficiency in Python and C++
• Hands-on experience optimizing deep learning workloads on modern GPUs
• Deep understanding of distributed training and inference techniques
• Experience with profiling tools across CPU, GPU, and distributed systems
• Familiarity with model compression techniques and their accuracy implications
• Strong grasp of memory hierarchies, communication primitives, and parallelism strategies
• Excellent measurement, debugging, and analytical reasoning skills
• Strong communication and collaboration skills
• Experience optimizing LLM inference at production scale
• Contributions to vLLM, TensorRT-LLM, DeepSpeed, or similar projects
• Familiarity with custom kernel authoring in Triton or CUTLASS
• Experience with FinOps for AI workloads
• Publications or talks on AI systems performance

Benefits

• Competitive base salary commensurate with experience, plus benefits.
• Full-time, direct W2 with Bright Vision Technologies (no C2C, no 1099, no third-party)
• No new H1B sponsorship available. H1B transfers welcomed for qualified candidates.
