Responsibilities

• We are looking for a Senior or Staff Inference Engineer to own the inference layer — combining deep model inference expertise with systems engineering to deliver a context-aware runtime serving finetuned SLMs across cloud, on-premises, and widely used GPU platforms.
• This is a hands-on individual contributor role working closely with Uniphore’s research, model engineering, knowledge systems, agent, and pla4orm teams.
• Integrate context selection, compression, conversation compaction, and persistent task state with model execution.
• Adapt context budgets, model selection, and reasoning effort to each task.
• Build paged KV-cache and prompt-prefix-cache management, cache-aware routing, retention, eviction, and offloading.
• Preserve correctness as context, permissions, model versions, and adapters change.
• Implement and tune speculative decoding, aQention kernels, continuous batching, quantization, chunked prefill, and multi-GPU parallel execution.
• Build model and adapter lifecycle management, multi-adapter serving, zero-downtime hot swapping, and resource scheduling.
• Implement observability (DCGM, Prometheus, Grafana), tenant isolation, overload protection, failure recovery, and safe rollout and rollback.
• Build portable runtime integrations across NVIDIA and AMD GPU pla4orms, cloud and on-premises environments, and single- or multi-GPU configurations.
• Autoregressive generation, prefill vs. decoding, aQention architectures, compute- vs. memory-bound execution, numerical precision.
• DraY-and-verify execution, acceptance/rejection sampling, adaptive speculation, and throughput tradeoffs.
• FlashAQention-style kernels, tiling, operator fusion, memory access paQerns.
• CUDA, HIP, Triton, or CUTLASS proficiency.
• Token budgeting, context selection, prompt compression, conversation compaction, sliding window and sparse aQention.

Requirements

• Continuous batching, chunked prefill, admission control, quantization, multi-GPU parallelism, prefill/decode disaggregation.
• 3+ years engineering, including hands-on with GPU systems, distributed inference, or ML serving • Production experience with vLLM, SGLang, or TensorRT-LLM • Strong Python and C++ (C++17/20)ti ability to read and debug CUDA C++ or HIP kernels • Hands-on GPU profiling and performance optimization

Preferred

• Paged KV storage, fragmentation, cache quantization, offloading, cross request prefix reuse, tenant isolation.
• Custom GPU kernel development (CUDA, HIP, Triton, CUTLASS) • PyTorch internals — torch.
• Compile, custom operators, MoE or disaggregated prefill/decode • LoRA/SLM adapter serving and zero-downtime hot swapping • NVIDIA and AMD Instinct hardware in production • Telemetry with DCGM, AMD SMI, Prometheus, and Grafana Hiring Pay Range: $159,000 - $198,800 Benefits : In addition to competitive base pay, this position also includes an annual incentive opportunity based on target achievement, pre-IPO stock options, benefits including medical, dental, vision, 401(k) with a match, and more, plus generous paid time off, paid holidays, paid day off for your birthday and other paid leave policies to support employees through all phases of life.
