Senior/Staff Software Engineer - ML Infrastructure

Who Are We Industrial labor is incredibly dangerous work – almost 3 million people in the US per year are injured in the workplace for entirely preventable and at times, fatal or debilitating causes. Protecting these essential people who power our world is what motivates Voxelitos, and we’d love for you to join us. At Voxel, we’re passionate about revolutionizing workplace safety and operations with groundbreaking, full-stack AI and computer vision technology. Voxel’s site intelligence platform helps safety and operations leaders see the unseen risks, make strategic decisions, and prevent workplace incidents before they happen. Our customers include Fortune 500 companies across major grocers and retailers, manufacturers, food and beverage warehouse operations, supply chain and logistics service providers. Based in SF with team members sitting all over the globe, Voxel is backed by industry leading VC’s. Voxel is looking for a Staff Machine-Learning Infrastructure Engineer to drive the next wave of our computer‑vision platform for workplace safety. You will be the technical owner for three pillars of our ML lifecycle – ground‑truth data & labeling workflows, large‑scale training infrastructure, and continuous model lifecycle management . If you excel at designing cloud‑native, distributed systems that turn raw video into production‑ready, version‑controlled models, we’d love to meet you. What You’ll Do Own data & labeling pipelines – architect scalable labeling services (storage, query, retrieval), design ontologies, automate annotation workflows, and build quality‑tiered datasets that stay within cost constraints. Build and operate training infrastructure – create multi‑GPU / multi‑node training frameworks (Ray, Spark, Kubernetes), optimize distributed jobs, and integrate accelerators (TensorRT, CUDA‑graph, FP8, etc.). Manage the full model lifecycle – stand up model registries, version control, evaluation suites, and continuous‑learning loops that push updates from dev → staging → prod with zero‑downtime rollbacks. Provide technical leadership, mentorship, and lightweight project management to a small infra + research squad. Establish DevOps‑for‑ML best practices (IaC, CI/CD, observability, cost monitoring) so researchers can iterate quickly and safely. Partner with ML engineers on architecture decisions, from data schemas to inference optimizations, ensuring infra and research road‑maps stay tightly aligned. Qualifications (Must Haves) Bachelor’s (or higher) in Computer Science, EE, or related field. 5+ years building and operating large‑scale infrastructure, with at least 3 years focused on ML or data‑intensive systems . Proven record designing highly available, distributed systems on Kubernetes (EKS, GKE, or on‑prem). Deep expertise with orchestration (K8s operators, Argo, Kubeflow), and cluster‑scale storage / compute (S3, GCS, Ray, Spark, Dask). Hands‑on experience automating data‑labeling or ground‑truth workflows and maintaining dataset versioning. Strong software‑engineering fundamentals; familiar with best practices for testing, observability, and secure coding. Demonstrated DevOps mindset – IaC (Terraform/CDK), CI/CD (GitHub Actions, ArgoCD), metrics & alerting (Prometheus/Grafana). Nice‑to‑Haves Experience running multi‑instance / multi‑GPU training jobs, mixed‑precision optimizations, or TensorRT / Triton inference. Familiarity with active‑learning, continuous‑training, or online distillation pipelines. Background in model registry tooling (MLflow, BentoML, SageMaker Registry) and evaluation dashboards. Prior work with computer‑vision models (YOLO, DETR, Faster R‑CNN) or video understanding at scale. Contributions to open‑source ML infra projects or published talks/blogs on MLOps. Exposure to edge‑deployment or real‑time inference systems. Experience shipping high quality production code in Python. Why Join Us? Join a visionary team revolutionizing safety and operations, directly impacting the well‑being of millions of essential workers. This is your chance to build an extraordinary business and foster a vibrant company culture that demands your absolute best. Alongside AI experts, experienced entrepreneurs, and passionate problem‑solvers, you’ll play a pivotal role in shaping the company’s growth trajectory and market position. Enjoy a competitive salary, benefits, and a dynamic work environment. Benefits Extensive / Generous health, dental, and vision insurance. Highly competitive paid parental leave and support system.
