Develop, prototype and test farm machinery and equipment modifications—including conveyors, planters, harvesters and post-harvest handling systems—to improve productivity, reliability and operator safety.
Lead the planning, budgeting and technical execution of agricultural engineering projects from feasibility studies through construction and commissioning, ensuring projects meet time, cost and quality targets.
Apply precision agriculture technologies (GPS/GNSS, RTK, variable-rate application, yield mapping, UAVs, multispectral imagery) to design site-specific management strategies that increase yields and reduce input use.
Prepare detailed engineering drawings, CAD models (AutoCAD, SolidWorks) and technical specifications for contractors and manufacturers, and review shop drawings for compliance with design intent.
Perform hydraulic calculations and design pumping systems, open channels, culverts and levees for effective farm water management, flood mitigation and drainage solutions.
Conduct crop water use and irrigation scheduling studies using evapotranspiration modeling, soil moisture sensors and remote sensing data to optimize irrigation timing and volumes.
Evaluate environmental impacts of agricultural operations, prepare environmental assessments and design mitigation measures for nutrient management, runoff control, and pesticide drift reduction.
Manage field trials, experimental plots and pilot demonstrations, including experimental design, data collection, statistical analysis and technical reporting to validate agronomic and engineering solutions.
Ensure compliance with local, state and federal agricultural, environmental and safety regulations, including permits for water use, pesticide application and construction on agricultural lands.
Provide technical support to farmers, extension services and internal stakeholders by diagnosing production constraints, recommending engineering and agronomic interventions, and delivering on-farm demonstrations.
Lead equipment testing and failure analysis, root-cause investigations and continuous improvement initiatives to enhance reliability, reduce downtime and lower lifecycle costs.
Prepare cost estimates, life-cycle cost analyses and business cases for capital investments in machinery, irrigation systems and processing infrastructure to support decision-making.
Design and implement post-harvest handling and storage systems—drying, cooling, ventilation and controlled-atmosphere storage—to minimize losses and maintain commodity quality.
Coordinate with multidisciplinary teams including agronomists, environmental scientists, mechanical and civil engineers, contractors and product development to integrate solutions across the value chain.
Develop standard operating procedures (SOPs), maintenance schedules and safety protocols for agricultural equipment, facilities and field operations to ensure operator safety and regulatory compliance.
Specify sensors, IoT devices and telemetry systems for remote monitoring of field conditions, equipment performance and water resources; integrate data streams for actionable farm management insights.
Write and contribute to technical proposals, grant applications and white papers to secure funding for research, pilot projects and infrastructure improvements in agricultural engineering.
Lead training workshops, technical extension sessions and client-facing presentations to transfer knowledge about new technologies, best practices and engineered solutions to growers and stakeholders.
Conduct risk assessments and business continuity planning for agricultural operations with a focus on climate resilience, water security and supply chain disruptions.
Review vendor proposals, manage procurement of equipment and services, and oversee contractor performance during equipment installation and construction phases.
Monitor emerging technologies and industry trends in precision agriculture, remote sensing, robotics and sustainable systems to recommend strategic adoption within the organization.

Secondary Functions

Assist in data collection, cleaning and basic analysis for agronomic and engineering studies; support data-driven decision-making and integration into farm management systems.
Contribute to the organization's sustainability and carbon mitigation initiatives by designing systems that reduce energy use, lower greenhouse gas emissions and improve nutrient efficiency.
Support cross-functional project teams with technical input for product development, pilot testing, and scale-up of agricultural technologies.
Maintain accurate project documentation, technical drawings, equipment manuals and as-built records for long-term asset management.
Participate in procurement evaluation, vendor negotiations and warranty claim processes to protect organizational interests and ensure equipment quality.
Support grant reporting, metrics tracking and communication of outcomes to funders, partners and stakeholders.
Provide mentorship and guidance to junior engineers, technicians and interns, including on-the-job training in field testing, CAD drafting and safety practices.
Maintain laboratory or workshop facilities by ensuring calibration of instruments, safe storage of chemicals and routine maintenance of test rigs and machinery.
Participate in industry events, conferences and standard-setting activities to represent the organization and influence best practices in agricultural engineering.
Coordinate emergency field support during critical farm seasons (planting/harvest) to resolve equipment failures, water delivery issues or other operational disruptions.
