About The Position

Lumafield is seeking an experienced, customer-facing engineer with expertise in Machine Learning (ML) to assist customers in achieving business objectives using CT-generated data. As an AI/ML Application Engineer, you will be responsible for developing, testing, and implementing ML models within customer engineering and manufacturing environments. These models will be applied to tasks such as defect detection, dimensional analysis, anomaly detection, and process control. The role involves both direct customer interaction and internal platform development. For customers, you will define the scope of ML applications, build and validate models using their data, and deploy them into their production workflows, offering support both remotely and on-site. You will collaborate closely with Project Managers and other customer-facing teams, including fellow Applications Engineers and Customer Success members. Internally, you will work with Product Management and Software Engineering to integrate common customer needs into the product and contribute to Lumafield's overall AI/ML strategy across the platform.

Requirements

4+ years of professional experience building, including depth in applied computer vision, including model development and evaluation on image or volumetric data.
Hands-on experience taking ML models from training into production, including deployment, monitoring, and retraining (MLOps)
Experience working directly with customers or other non-ML stakeholders to translate business and engineering problems into ML solutions.
Comfort operating in engineering and manufacturing environments, including working with team members on the production floor
Strong written and verbal communication skills, including the ability to present technical results to engineering, product, and executive audiences.
A track record of shipping pragmatic, useful models — balancing speed, quality, and customer impact.
Willingness to travel approximately 30%, primarily to customer sites
