Job Opportunities API

Job Description: We are looking for a Senior Inference Engineer with a strong foundation in software engineering, distributed systems, and performance optimization to build and optimize inference engines for large-scale LLM serving systems. You will work across both research and production environments, ensuring our LLM serving systems are fast, scalable, and efficient. The role spans the entire inference stack — from kernel and runtime to scheduling, memory management, and distributed execution Key Responsibilities: Profile, benchmark, and analyze bottlenecks for LLM inference workloads across multiple layers: kernel, memory, networking, and scheduler Optimize inference engines (vLLM, SGLang, TensorRT-LLM) for throughput, latency, memory efficiency, GPU utilization, and cost Implement and fine-tune inference optimization techniques including batching, KV-cache management, quantization, speculative decoding, parallelism strategies, and disaggregated serving Build instrumentation and profiling tools to identify bottlenecks Ensure the reliability of the inference pipeline through A/B launches, rollback, model versioning, and fault tolerance Collaborate with the Platform Engineering team to improve serving architecture based on performance findings Document and share knowledge, contributing to internal best practices and AI open-source projects whenever possible Requirements 1 - Mandatory: At least 5 years of experience as a Software Engineer, Performance Engineer, or equivalent. Strong foundation in Software Engineering, Software Architecture, and Distributed Systems. Proficiency in at least one of the following languages: Python, Go, or C++. Experience developing or optimizing distributed systems, high-throughput backends, or large-scale serving systems. Experience with benchmarking, profiling, and performance tuning in production environments. Ability to analyze CPU, Memory, Network, or Storage bottlenecks. Strong systems thinking, Root Cause Analysis capabilities, and the ability to solve complex performance problems. Strong ownership mindset and the ability to work independently. 2 - Nice to Have: Experience with Linux internals, kernel tuning, or custom Linux kernel. Understanding of GPU Architecture or CUDA Programming. Experience with AI/ML Serving Systems or LLM Inference.- Have worked with one of the inference engines such as vLLM, SGLang, TensorRT-LLM, or Triton Inference Server. Understanding of batching, KV Cache, quantization, speculative decoding, tensor/pipeline parallelism, or disaggregated serving. Experience with the NVIDIA inference stack (TensorRT, Triton, CUTLASS, NCCL, cuBLAS, cuDNN). Experience with observability stacks such as Prometheus, Grafana, or OpenTelemetry. Open-source contributions or research related to AI Infrastructure, ML Systems, or Performance Optimization.
