Senior Process Manager — Single-Crystal CVD Diamond Growth

Company: KK Exports

Location: Surat, India (on-site)

, Senior level

Reports to: Senior Engineering Leadership

About the role

KK Exports is building a world-class single-crystal CVD diamond growth operation and is hiring a Senior Process Manager to own day-to-day reactor operations, material output, and process performance. This is a hands-on technical leadership role for an engineer who thrives on the shop floor, takes personal responsibility for the single-crystal diamond coming out of the reactors, and wants a meaningful R&D; component in their week. You will translate growth specifications from senior engineers into reliable, repeatable, high-quality single-crystal production, and dedicate roughly a quarter of your time to development work that pushes the process forward.

Responsibilities:
Process ownership (≈ 75%)
- Own single-crystal CVD diamond growth recipes, reactor operation, and run-to-run consistency
- Implement specifications and growth protocols defined by senior engineers,



and drive them to repeatable production
- Take personal responsibility for crystal quality, growth rate, sector control, and process performance metrics
- Lead substrate preparation, seed handling, in-run monitoring, and post-growth inspection workflows
- Coordinate with maintenance, gas handling, and metrology teams to keep reactors in spec
- Diagnose excursions and lead root-cause analysis on defects, inclusions, twinning, color, and yield loss
- Maintain rigorous process documentation, run logs, and traceability for every stone produced
- Mentor and supervise process engineers, technicians, and operators

R&D; (≈ 25%)
- Design and execute development experiments: nitrogen/oxygen chemistry tuning, temperature and pressure regimes, seed selection and preparation, step-growth strategies, multi-cycle growth
- Collaborate with senior engineers on reactor design improvements and next-generation growth campaigns
- Characterize
