Senior AI Infrastructure Engineer - Computer Vision

ABOUT OBVIO AI Each year, more than 40,000 people in the U.S. leave home and never make it back due to traffic crashes. At Obvio, we believe these deaths are preventable. We deploy solar-powered, AI-assisted cameras to enforce traffic laws where pedestrians are most vulnerable—automating enforcement in ways that traditional systems cannot. Our approach has already led to a 50% reduction in reckless driving in early partner cities. Founded by the team behind Motive's AI dashcam and backed by Bain Capital Ventures and Khosla Ventures, we are building the intelligence layer for safer streets globally. WHAT YOU'LL DO Build the orchestration layer. Design and implement a scalable workflow system to ingest, route, and process incoming events. Define the stages of the pipeline — ingestion, preprocessing, inference, validation, and delivery — and build something that handles failures gracefully at high throughput. Scale the inference fleet. Build the compute layer that parallelizes processing across the event backlog and handles burst capacity as our camera fleet grows. Design the worker pool, queueing, and autoscaling strategy for GPU-bound workloads on ECS. Design the data plumbing. Own the path from edge device to pipeline output — storage, metadata, and the triggers that drive processing. Build something that is observable, debuggable, and auditable end-to-end. Build the model serving and lifecycle layer. Stand up the infrastructure that loads versioned CV models and handles inference reliably. Optimize for GPU utilization and throughput where it matters — dynamic batching, multi-model serving, and model optimizations like quantization or TensorRT/ONNX. Ensure new model versions can be promoted and rolled back without pipeline downtime. Set the engineering standard. This is an early hire. You'll write the playbooks — runbooks, deployment procedures, testing standards — that the team builds on as we grow. WHAT WE'RE LOOKING FOR Depth in backend systems. 6+ years building and operating production backend or data-intensive systems at scale, with meaningful experience working on ML-heavy pipelines. You've owned something through its full lifecycle — design, deployment, scaling, and on-call — and you've done it in a context where ML inference was a first-class part of the system. Hands-on orchestration experience. You've used a workflow orchestration tool to build production pipelines, not just evaluate them. You understand the tradeoffs between options and can make a principled choice for our use case. Strong cloud infrastructure fundamentals. Comfortable with the building blocks — compute, queues, storage, networking — and you think in terms of cost, reliability, and operational simplicity rather than just what works. Enough ML systems fluency to orchestrate them well. You've built or operated pipelines where ML inference is a core stage, and you understand what those workloads need — throughput constraints, GPU economics, model versioning, and keeping model performance visible in production. You don't need to have trained the models, but you know how to run them reliably at scale. Experience with CV or video pipelines is a plus. Pragmatic decision-maker. You don't reach for the first framework you know. You understand the problem, evaluate tradeoffs honestly, and build something that fits the actual scale and constraints. WHY OBVIO Mission. Your work will directly help save lives and improve road safety. Ownership. You'll make foundational architectural decisions during a critical phase of our Series A growth. Impact. This isn't a maintenance role. You are being hired to build the core ML infrastructure layer from the ground up. Growth. Competitive compensation, early-stage equity, and the opportunity to build a world-class ML platform organization.
