Senior Process Manager — Single-Crystal CVD Diamond Growth

Company: KK Exports

Location: Surat, India (in office)

, 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
