Fantastic challenges. Amazing opportunities.

GKN Aerospace is reimagining air travel: going further, faster and greener! Fuelled by great people whose expertise and creativity sets the standards in our industry, we’re inspired by the opportunities to innovate and break boundaries. We’re proud to play a part in protecting the world’s democracies. And we’re committed to putting sustainability at the centre of everything we do, opening up and protecting our planet.

With over 16,000 employees across 32 manufacturing sites in 12 countries we serve over 90% of the world’s aircraft and engine manufacturers and achieved sales of £3.6bn in 2025. There are no limits to where you can take your career.

Provide technical environmental engineering support for water, wastewater, stormwater, spill-prevention, and water-resource compliance at an aerospace and defense manufacturing site producing acrylic and glass aircraft transparency products.

Protect receiving waters, sewer systems, groundwater, employees, neighbors, and operational continuity by implementing compliant and practical controls for process wastewater, industrial stormwater, cooling/rinse systems, chemical storage, secondary containment, washdown, wastewater pretreatment, sampling, and reporting.

Translate federal Clean Water Act/NPDES concepts, California Water Board requirements, Santa Ana Regional Water Quality Control Board expectations, local City of Garden Grove environmental compliance interfaces, and customer/audit expectations into reliable daily execution for acrylic casting/forming, solvent bonding, coatings, glass processing, finishing, maintenance, and utilities.

• Maintain and improve the site SWPPP, site maps, drainage maps, pollutant source assessments, BMPs, inspection forms, monitoring schedules, and SMARTS records.
• Conduct or coordinate stormwater inspections, qualifying storm event sampling, pollutant source tracing, benchmark/NAL evaluations, corrective actions, and annual reporting.
• Evaluate outdoor operations, raw material areas, waste staging, tanks, loading docks, roof drains, dust collectors, pallets, scrap, maintenance yards, and chemical storage for exposure to stormwater.
• Lead corrective actions for stormwater exceedances, including source identification, BMP upgrades, employee training, housekeeping improvements, structural controls, and treatment options.

• Evaluate process wastewater streams from acrylic casting/forming, glass grinding/cutting, polishing, rinsing, coating support, equipment cleaning, cooling, utilities, and maintenance activities.
• Support wastewater discharge authorizations, local sewer authority reviews, pretreatment requirements, sampling, flow estimates, source-control programs, and records.
• Monitor and troubleshoot pollutant parameters such as pH, TSS, COD/BOD, oil and grease, metals, solvents, coolants, suspended solids, and process-specific constituents.
• Partner with facilities and operations to maintain treatment systems, sumps, interceptors, neutralization equipment, filters, holding tanks, pumps, valves, and discharge controls.

• Assess water-related risks associated with MMA/monomer areas, solvent bonding, coatings, tanks, totes, drums, autoclaves, ovens, dust collectors, saws, grinders, CNC equipment, and polishing lines.
• Design or recommend secondary containment, drain protection, isolation valves, berms, covers, diversion, treatment, spill kits, storage layouts, and storm-resistant shelters.
• Support Management of Change and capital projects to ensure new equipment, chemicals, production lines, tank systems, and utilities address water quality and wastewater impacts before startup.
• Develop practical procedures for washdown, equipment cleaning, spill cleanup, wastewater transfer, sampling, and safe maintenance of water-handling equipment.

• Support compliance with Clean Water Act/NPDES concepts, California Industrial General…
