Founding ML Engineer, Computer Vision (Object Detection)

ABOUT THE ROLE
As the founding machine learning engineer, you will set the technical direction for fine-grained visual item identification at an internet marketplace platform. You will build production models that identify specific brands, models, editions, and variants, helping users make informed decisions with confidence.
WHAT YOU'LL DO
- Design and own computer vision architecture, adapting foundation vision models to specialized catalog identification.
- Define category-level accuracy standards and develop calibrated confidence scoring so the product can communicate uncertainty.
- Build feedback loops that use model errors to guide labeling priorities in partnership with the labeling team.
- Balance broader category coverage against deeper accuracy in existing categories.
- Own the path from model research to production serving, including latency, cost, and reliability.
- Explain model capabilities and tradeoffs to technical and non-technical stakeholders.
WHAT WE'RE LOOKING FOR
- At least 5 years of applied computer vision experience, including production systems delivered at meaningful scale.
- Hands-on experience with fine-grained or instance-level recognition, distinguishing between visually similar items where near-misses are not sufficient.
- Production experience fine-tuning and deploying vision transformers or CNNs with PyTorch or TensorFlow.
- Experience adapting foundation vision models to specific use cases or catalogs.
- Ability to design and run evaluation frameworks that measure model improvements beyond training loss.
- Experience with calibrated confidence scoring and ownership of model serving decisions, including latency, cost, and reliability.
- Strong written and verbal communication, and comfort providing technical leadership on an open-ended problem.
