Leather production manager: Leather production managers plan all aspects of the leather production process. They ensure the required throughput of the factory in terms of quality and quantity of the leather. They organise the production staff. They monitor and ensure the operation of machinery and equipment. They cooperate with managers of each production department.
Leather laboratory technician: Leather laboratory technicians perform and report chemical analyses and physical tests of leather. They also perform and report chemical analyses of auxiliaries, environmental emissions and discharges. They ensure that the tests are carried out according to appropriate national, international or customer standards.
Colour sampling technician: Colour sampling technicians prepare recipes of colours and dyeing mixes. They ensure consistency in colour while using materials from different sources.
Leather finishing operations manager: Leather finishing operations manager plan and organise the work of the finishing department. They are in charge of chemical supply and equipment management. They also coordinate the staff.

Test leather chemistry is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.

Tanner: Tanners program and use tannery drums. They perform the work according to the work instructions, verify the physical and chemical characteristics of the hide, skin, or leather and of the liquid floats (e.g. pH, temperature, chemicals concentration) during the process. They use the drum for washing the hide or skin, removing the hair (not in the case of hides and skins tanned with the hair or wool on), bating, tanning, retanning, dyeing and milling.
Colour sampling operator: Colour sampling operators apply colours and finish mixes according to the defined recipes. They apply pigments, dyes or other finishing mixes.

Leather finishing operator: Leather finishing operators use machines for finishing leather according to the required specifications by the client for surface characteristics such as colour nuance, quality, pattern and special properties such as waterproofness, antiflame retardance, antifogging of the leather. They arrange the dosage of finishing mixes to apply to the leather and do the routine maintenance of the machinery.
Leather goods product development manager: Leather goods product development managers coordinate the leather goods design and product development process in order to comply with marketing specifications, deadlines, strategic requirements and policies of the company. They communicate and collaborate with other cross functional teams or professionals involved in leather goods production, such as logistics and marketing, costing, planning, production and quality assurance. They are responsible for the leather goods product collections development which involve activities such as tracking style development, reviewing design specification in order to meet the design vision, the manufacturing environment, and the rent-ability of the companies.
