Joinery Technician (Sintered Stone & Quartz)

About the role

Newmatic Countertops Limited is hiring a Joinery Technician in Westlands, Nairobi, to join and finish countertops made from sintered stone and quartz. The role covers joining, edge fabrication, polishing and finishing, with a focus on accuracy, quality and meeting production targets.

Key responsibilities

• Read job cards, templates and drawings to confirm dimensions, edge profiles and joint positions.
• Prepare 45-degree mitres for corner joints, waterfalls and returns, and build double-lipped (laminated) edges with bonded strips.
• Mix and apply adhesives and colour-matched resin, then clamp, level and align pieces so seams are tight and flush.
• Grind and polish joints and edges with hand polishers and progressive diamond pads, matching the slab finish (polished, honed or matt).
• Inspect every piece for scratches, chips, burn marks and uneven seams and rework as needed.
• Handle slabs and finished pieces safely with lifting aids, A-frames and trolleys, and keep tools, pads, blades and clamps clean and in order.
• Record material used and report offcuts, damages and shortages, and meet daily and weekly production targets and delivery deadlines.
• Support cutters, installers and other team members when workload requires.

Required profile

• At least 1 year of hands-on experience in countertop joinery, stone or quartz fabrication, or a similar workshop trade.
• Proven ability to join accurate 45-degree mitres and build double-lipped edges.
• Experience polishing stone, quartz or sintered stone with hand polishers and diamond pads.
• Good eye for detail: tight seams, flush joints, consistent edge thickness and colour matching.
• Able to read measurements, templates and job cards, and use a tape measure, square and level accurately.
• Physically fit, reliable and punctual, able to work to deadlines.
• Preferred: direct experience with sintered stone, training or certificate in joinery, carpentry, masonry or stone fabrication, and ability to train junior assistants.

• 45-degree mitre joinery and double-lipped edge fabrication
