Senior Mechanical Design EngineerWe are looking for an exceptional Senior Mechanical Design Engineer to architect and develop the mechanical systems for next-generation liquid level sensing technologies used in the world's most demanding heavy equipment environments. This role is intended for a deep technical engineer who thrives on difficult engineering challenges. The products developed in this position must operate reliably in extreme temperatures, high vibration environments, and harsh industrial conditions where failure is not acceptable.
The ideal candidate has previously designed rugged electromechanical products from concept through production, with strong expertise in sensor packaging, vibration-resistant design, sealing strategies, and harsh-environment electronics integration. Sensors developed in Dallas will be deployed globally across construction, agriculture, mining, and commercial vehicle platforms.ResponsibilitiesDesign the mechanical architecture for advanced liquid level sensing systems, including: guided wave radar probes, capacitive sensing structures, and ultrasonic sensor housings.Develop sensor designs capable of surviving years of operation in extreme duty cycles.Create mechanical systems that withstand: severe vibration and mechanical shock, extreme temperature ranges (– 40°C to +125°C+), fluid exposure and chemical attack, and dust, contamination, and pressure variations.Focus on areas including: structural integrity, sealing and environmental protection, electronics packaging, probe and waveguide design, and material selection for durability and corrosion resistancePerform deep failure analysis and root cause investigations.Solve problems related to: vibration-induced fatigue, thermal expansion mismatches, fluid interaction with sensing structures, long-term reliability of ruggedized electronics packaging •Design and perform FEA analysis on designs for rapid failure analysisOwn the mechanical design from concept through production.Lead prototype development, testing, and design iteration.Drive design decisions balancing performance, reliability, manufacturability, and cost.Work within automotive-grade development systems including: APQP, DFMEA / PFMEA, design verification and validation testingSupport development processes aligned with IATF 16949 quality systems.Required ExperienceBachelor's or Master's degree in Mechanical Engineering.10–15+ years of experience designing rugged industrial or automotive products.Proven track record developing mechanical systems for electronic sensors or instrumentation.Strong experience in several of the following areas: harsh environment product design, ruggedized electronics packaging, vibration and fatigue-resistant mechanical systems, fluid-contact sensor structures, sealing systems and ingress protection, and materials engineering for extreme environmentsAdvanced experience with 3D CAD systems.Experience using FEA tools for structural, vibration, and thermal analysis.Experience working within automotive-grade product development systems, including: APQP, DFMEA / PFMEA, environmental validation testing, and IATF 16949 environments.PreferredMechanical design of liquid level sensorsExperience with guided wave radar probes or instrumentationHeavy vehicle, construction equipment, or agricultural machinery developmentEMI/EMC-conscious electronics packagingDesign for IP67 / IP69K environmental protectionExperience designing products for long service life in high vibration environmentsA hands-on mechanical architect, not just a CAD designerComfortable solving complex physics and materials problemsExperienced designing products that survive in extreme environmentsMotivated to create highly reliable sensor systems used worldwideTravel RequirementsUp to 10% travel may be requiredPhysical RequirementsWhile performing the duties of this job, employees may be required to walk for prolonged periods of time, occasionally bending, climbing, rotating, squatting, reaching, kneeling, or stooping, lifting up to 40 pounds, and periods of computer use.Employee may be frequently exposed to heat/cold, heights, gases, vibration, dust, chemicals, odors, dampness, fumes, and noises.Reasonable AccommodationsReasonable accommodations may be made to enable individuals with disabilities to perform the essential functions of the position.What's Nice About Working For RochesterComprehensive Health InsurancePaid Time Off and HolidaysLife, AD&D, short/long term disability insuranceCasual workplace with an unbelievable feeling of energy401K Retirement program with company match
