Director of Mixing & Compounding (Rubber)The Director of Mixing & Compounding will oversee rubber production including milling & textile operations across two manufacturing plants with 200 total employees, 6-8 Direct Reports (Department Managers), responsible for safety, quality, delivery, and cost accountability, acting as leader for both operations.
Location: Columbia, MO (Relocation offered for candidates moving).
Compensation: $175,000 - $210,000 base salary + 15% bonus.
Benefits: Medical, Dental, Vision, STD, LTD, 401k Match 6%, 3 weeks vacation, Tuition Assistance, etc.
Key ResponsibilitiesOperational Leadership & Plant Management
- Hold full P&L, safety, quality, delivery, and
cost accountability for both mixing and cord production sites, acting as
the plant manager for each operation.
- Lead, develop, and hold accountable a team of 6-8
managers who in turn lead roughly 200 salaried and hourly employees across
multiple shifts.
- Develop and execute annual operating plans, capital
plans, and budgets; manage conversion cost, yield, scrap, rework, material
variance, and overhead against targets.
- Balance production schedules and capacity across
both sites to meet downstream Belt and Hose demand, optimizing
changeovers, inventory, and material availability.
- Partner with the VP of Manufacturing, plant managers
of downstream operations, supply chain, and commercial teams on demand
planning, capacity strategy, and make-versus-buy decisions.
- Spend meaningful time on the floor at each site
(approximately 30% travel), maintaining a visible presence on all shifts
and engaging directly with operators and supervisors.
Compound Quality, Technology & Process Control
- Own end-to-end compound consistency, using rheology
(Mooney, MDR/RPA), physical properties, and downstream processing and
molding results as the measures of success.
- Reduce process variation through structured methods
such as design of experiments (DOE), statistical process control,
capability studies, and root cause analysis.
- Develop, standardize, and improve mixing programs
(load order, ram pressure, rotor speed, mix time, dump temperature,
energy-based and multi-stage mixing) for new and existing compounds,
including EPDM, CR, HNBR, NBR, SBR, and NR systems.
- Oversee textile operations (cord unwinding, coating,
and rewinding) and raw material handling, heating, and cooling to ensure
consistent adhesion and reinforcement performance in finished belts and
hoses.
- Lead cross-functional troubleshooting with chemists,
the materials lab, process and manufacturing engineers, and downstream
operations, leading investigations through disciplined experimentation.
- Establish a single, controlled system of work
instructions, batch cards, and process parameters across both sites so
that the same compound is produced the same way regardless of site, shift,
or operator.
- Evaluate and recommend mixing equipment, automation,
weighing/batching, and tooling options for current and new processes and
products.
Mill: raw materials are received and handled, then weighed, mixed, heated, and cooled to produce uniform rubber compound for downstream belt and hose production.
Textiles: cord is carefully unwound, coated, and rewound to specification, giving finished products consistent strength and adhesion.
Safety, Compliance & Culture
- Champion a zero-harm safety culture, including
lockout/tagout, machine guarding, mill nip and pinch-point hazards, hot
surfaces, combustible dust, and chemical handling.
- Ensure compliance with OSHA, EPA, environmental
permitting, SDS requirements, and applicable customer, ISO/IATF, and
corporate standards.
- Drive 5S, standardized work, and lean manufacturing
practices; treat housekeeping as both a safety and a quality requirement.
- Build a culture of accountability in which following
the documented process is the standard and deviations are surfaced openly.
Talent Development & Organizational Capability
- Build a bench of operators, leads, supervisors, and
managers through structured training, skills matrices, cross-training, and
succession planning.
- Set clear expectations, conduct performance reviews,
and partner with HR on coaching, corrective action, recognition, and labor
relations.
- Capture experienced operators' tribal knowledge and
convert it to documented, teachable standards.
- Attract, hire, and retain top technical and
operational talent in a competitive labor market.
Strategy & Continuous Improvement
- Work with the plant leadership and engineering
leadership to define annual improvement initiatives, then align
cross-functional teams to targets and track results.
- Lead capital projects, technology transfers, and
new-process launches from concept through ramp-up.
- Use KPIs, trend charts, and daily management
routines to drive visibility, problem solving, and sustained results.
- Contribute to the North American and global
compounding strategy, sharing best practices with sister sites and
corporate technology teams.
Key Performance Indicators
- Safety: recordable incident rate, near-miss
reporting, and audit results
- Compound first-pass quality and out-of-spec rate;
rheology capability and variation reduction
- Downstream molding and processing results
attributable to compound and cord
- Schedule attainment and on-time delivery to
downstream operations
- Scrap, rework, yield, and material and conversion
cost versus budget
- Equipment uptime and overall equipment effectiveness
(OEE)
- Operator qualification coverage and cross-training
depth
- Employee engagement, turnover, and leadership bench
strength
Qualifications Seeking:- Bachelor's degree in Engineering (Chemical, Polymer,
Mechanical, Materials, or Industrial), Chemistry, or a related technical
field preferred. Experience in lieu of Bachelors will be considered.
- 8+ years of manufacturing experience, including 5-10
years of hands-on polymer or rubber compounding and mixing experience.
- 5+ years of progressive leadership experience
managing managers and multi-shift operations, including responsibility for safety, quality, cost, and delivery.
- Strong working knowledge of internal mixers
(tangential and intermeshing), two-roll mills, TSE, weigh-up/batching, and
compound testing (Mooney, MDR/RPA, specific gravity, dispersion).
- Demonstrated experience reducing process variation
using DOE, SPC, and structured problem-solving methods.
- Proven ability to lead cross-functional
troubleshooting with chemists, lab, engineering, and production teams.
- Excellent written, verbal, and interpersonal
communication skills, direct without being abrasive.
- Willingness and ability to travel approximately 30%
between sites and to work on the floor in a manufacturing environment.
Preferred:- Master's degree in Polymer Science, Chemistry, or
Engineering, or an MBA.
- Experience in belt, hose, or other engineered rubber
product manufacturing, with understanding of rheology and downstream
extrusion, calendering, and molding.
- Experience with cord treatment, textile
reinforcement, or adhesive systems.
- Experience managing multi-site operations and
leading change across sites.
