Core Responsibilities

Primary Functions

Execute standardized jam, jelly, marmalade and fruit preserve recipes at commercial scale, following batch cards and written SOPs to consistently achieve targeted flavor, texture, color, and viscosity for each SKU.
Operate and maintain production equipment commonly used in preserves manufacturing including steam-jacketed kettles, vacuum cookers, ball cookers, hot-fill lines, homogenizers, filler heads, paddle mixers, and canning equipment while adhering to safety and lockout/tagout procedures.
Measure and adjust Brix (sugar concentration), pH, acidity and solids using refractometers, pH meters, and titration where required to ensure product meets shelf-stability and regulatory specifications.
Prepare raw fruit and ingredient components: wash, sort, peel, dice, macerate, and pre-cook fruit; weigh and stage sugars, pectins, acids, and flavorings according to recipe scaling and yield requirements.
Monitor in-process temperatures, cook times, vacuum levels and other critical control points (CCPs) and document readings in batch records and production logs to comply with HACCP plans and GMPs.
Perform sensory quality checks (appearance, aroma, mouthfeel, consistency) for each batch and flag deviations to the QA department; participate in corrective actions and root-cause analysis.
Execute hot-fill, cold-fill, water-bath or pressure canning processes and verify sterilization parameters, fill weights, headspace, and seaming integrity to ensure package safety and shelf life.
Label, date-code and batch-code finished goods accurately; follow FIFO inventory rotation and packaging instructions to maintain traceability and regulatory compliance.
Maintain clean-as-you-go and sanitation protocols, perform CIP (clean-in-place) or manual cleaning of kettles, valves, pumps, and production surfaces to meet GMPs and sanitation schedules.
Follow allergen control procedures to prevent cross-contact (e.g., nuts, dairy), including segregating ingredients, using color-coded utensils, and documenting cleaning between runs.
Scale and modify recipes under direction of the Head Cook or R&D to accommodate seasonal ingredient variability or changed production volumes while maintaining product identity and quality attributes.
Record yield, shrinkage, waste and material usage for each run and work with production planning to improve throughput and reduce cost-per-unit.
Support small-batch pilot runs and new product trials, documenting process parameters, deviations and sensory feedback to help refine commercial recipes and SOPs.
Train and mentor junior production staff and temporary seasonal employees on preserves-specific techniques, safety procedures and production workflows.
Maintain inventory of perishable and non-perishable ingredients, place ingredient and packaging orders with procurement when necessary, and report shortages or quality issues.
Conduct periodic equipment checks and basic troubleshooting (e.g., flow issues, pump cavitation, gasket replacement) and escalate mechanical repairs to maintenance while logging downtime.
Adhere to company food safety programs and participate in internal and external audits (HACCP, SQF, BRC, or local regulatory inspections) by providing accurate documentation and demonstrating compliant processes.
Implement portion control, target weights and fill tolerances during bottling/filling to meet net-weight regulations and minimize rework.
Coordinate with packaging and warehouse teams to ensure finished goods are palletized, shrink-wrapped and stored at appropriate temperatures until distribution.
Maintain organized batch documentation, SOPs, and production checklists with attention to detail to ensure every lot is fully traceable from ingredient receipt through finished goods.
Contribute to continuous improvement initiatives by suggesting process optimizations, ingredient substitutions for cost savings, or improvements to flavor consistency and shelf stability.
Practice safe knife skills and safe handling of hot sugar processes, monitoring for burn risks and implementing protective equipment for team members.
Support seasonal product launches and high-volume periods by working flexible shifts and helping plan production schedules to meet customer demand.

Secondary Functions

Participate in product photography or sample preparation for marketing and customer feedback sessions when needed.
Assist the R&D team with scaling pilot recipes into production-ready formulations and advise on practical production constraints.
Help update training materials, recipes, and SOPs to reflect process changes and lessons learned from production runs.
Support inventory audits and reconciliation by providing accurate usage and waste reports.
Maintain positive relationships with growers or ingredient suppliers by communicating fruit quality or delivery concerns to procurement.
Engage with sustainability initiatives, recommending reductions in single-use plastics, optimizing packaging size, or repurposing trim waste where safe and feasible.
Provide cross-training coverage for other small-batch production roles (e.g., preserves to curds or chutneys) to maintain production continuity.
