Founding ML Engineer, Computer Vision (Object Detection)

ABOUT THE ROLE As the founding machine learning engineer, you will set the technical direction for computer vision in an early-stage resale marketplace. You will build and productionize models that identify items from images with the accuracy and confidence needed to support trustworthy pricing and customer decisions. WHAT YOU'LL DO - Design computer vision architecture for fine-grained item identification, building on foundation models and adapting them to a specific catalog. - Define accuracy standards by category and develop calibrated confidence scores so the product can recognize when it is uncertain. - Build feedback loops that use model errors to guide future labeling and model improvement. - Set priorities between expanding category coverage and improving accuracy in existing categories. - Own the path from research to production, including model serving latency, cost, and reliability. - Communicate model capabilities and limitations to technical and non-technical stakeholders. WHAT WE'RE LOOKING FOR - At least 5 years of applied computer vision experience, including a system shipped to production at meaningful scale. - Experience with fine-grained or instance-level classification, where distinguishing similar items matters. - Strong PyTorch or TensorFlow skills, with production experience fine-tuning and deploying vision transformers or CNNs. - Experience building evaluation frameworks that measure real-world model performance and improvement. - Comfort serving as the senior technical voice on an open-ended problem without an established playbook, and explaining tradeoffs to non-technical stakeholders. - Experience with active learning or human-in-the-loop labeling, low-latency model APIs, or an early-stage startup is valuable. COMPENSATION & BENEFITS Annual salary range: $200,000 to $260,000. LOCATION Fully remote within North America.
