[Remote] Senior Software Engineer, Machine Learning Inference Platform

Note: The job is a remote job and is open to candidates in USA. Stack AV is developing revolutionary AI and advanced autonomous systems designed to enhance safety, reliability, and efficiency in the trucking transportation industry. In the Senior Software Engineer role, you will own meaningful subsystems of the inference platform, driving them from design through production while mentoring other engineers and ensuring timely delivery.ResponsibilitiesOwn technical design and delivery of subsystems in a high-throughput, low-latency inference platform capable of handling multi-tenant, enterprise-grade inference workloadsDevelop robust API layers (gRPC, WebSockets, REST, etc.) and developer SDKs that abstract complex distributed inference orchestration into seamless, reliable token streamsBuild and harden a multi-tenant control plane to enable accurate metering, rate limiting, quotas, tenant isolation and noisy-neighbor fairness across the platformOptimize inference performance across the entire system stack, including the model engine layerBuild observability and SLOs to gain insights into system economics, cache-hit rates, GPU utilization and cost accounting per model and per tenantPartner with product and infrastructure teams on model onboarding, capacity planning, external API contracts and customer adoptionDecompose ambiguous work, drive issues to closure, and raise the engineering bar through code quality, reviews, testing, and mentoringSkillsBachelor's or Master's degree in Computer Science, Engineering, or a related field4+ years of experience building and operating backend distributed systems end to endStrong Data & ML systems fundamentals: data-intensive distributed systems, concurrency, networking and performance profilingHands-on experience with large-scale inference services on GPUs, including KV caches, prefill/decode stages and throughput/latency trade-offsDirect experience with inference engines (TensorRT, vLLM, etc) or serving frameworks (Dynamo, Triton or equivalent)Strong programming skills in C++, Go, Rust or PythonFamiliarity with deep learning frameworks (PyTorch, etc.) as well as model parallelismFamiliarity with GPU computing primitives such as CUDA, NCCL, NVLink, and hardware-specific optimizationsPractical understanding of high-performance networking architectures, including InfiniBand, RoCE, and low-latency cluster communicationStrong analytical and problem-solving skillsAutonomous vehicles (AV) experience is a bonusCompany OverviewStack AV operates in the transportation industry that develops advanced autonomous systems.
