Technical Manager

Role & responsibilities:

• Develop new construction chemical formulations and improve existing products across the full range: wall putty, tile adhesives (C1 to C2TES2 grades), tile grouts (cementitious and epoxy), waterproofing compounds and coatings, concrete admixtures, repair mortars, micro concrete, block-jointing mortars, ready-mix plasters, crack fillers, and bonding agents.

• Lead bench-scale trials through to plant-scale-up, ensuring formulations are reproducible and stable across all factory locations.

• Drive cost optimisation of formulations through raw material selection and substitution (cement, RDP, HPMC/cellulose ethers, fillers, admixtures such as plasticisers, accelerators and retarders, and other additives) without compromising performance.

• Ensure all products meet relevant IS, EN, and ASTM standards (e.g. IS 15477 for tile adhesives, EN 12004 classifications).

• Set up and oversee testing protocols adhesion, open time, slip, water resistance, compressive/flexural strength, and shelf-life studies.

• Manage, mentor, and develop R&D/QC Executives; allocate projects, review trial data, and build lab capability.

• Maintain a structured formulation library, trial records, and technical documentation for all products.

• Support the Commercial team with technical inputs for customer-specific product development and tolling / contract manufacturing discussions.

• Evaluate and qualify new raw material vendors in coordination with Procurement, including sample assessment and benchmarking.

• Provide technical troubleshooting support to production and to customers on application issues.

• Track industry trends, competitor products, and new raw materials to keep Gemini's range competitive.

• Implementation of systems in line of ISO as is applicable.
