Principal Mechanical Engineer

Sedron Technologies is hiring a talented Principal Mechanical Engineer – Design & Structural focused, to work remotely within the United States!   

Sedron is a leading provider of circular waste management technologies for agricultural manure and municipal biosolids processing, deploying facilities across several North American regions. Since its founding in 2014, Sedron has pioneered innovative solutions, including the patented Varcor® system, to transform waste into clean water, organic fertilizer, and carbon-negative commodities. With strong engineering expertise, Sedron’s processes reduce nutrient pollution, lower operational expenses, and promote sustainability at a fraction of traditional costs. 

We are seeking a Principal Mechanical Engineer with a focus on structural design and analysis in heavy industrial equipment to lead the development, analysis, and long-term reliability of Sedron’s advanced mechanical systems. This role blends deep industrial machinery expertise, advanced structural/welded system knowledge, and lifecycle engineering leadership. You will shape complex mechanical systems from concept through commissioning while safeguarding the structural integrity, reliability, and performance of equipment operating in demanding, continuously loaded environments. 

This is a top-tier technical role, ideal for an engineer with 20+ years of experience designing, analyzing, and validating large-scale rotating machinery, welded structures, pressure vessels, and industrial equipment operating under high loads, high temperature differentials, and severe duty cycles. 

Because we design, build, commission, and operate our technologies, we are looking for individuals who can meet the following essential functions of the position:  

• Serve as Sedron’s senior technical authority on heavy industrial machine design, rotating equipment, pressure vessel design, and welded/structural systems. 
• Provide SME-level guidance to engineers company-wide, including structural integrity reviews, failure analysis, design improvement strategies, and advanced analytical support. 
• Lead cross-disciplinary design reviews, risk assessments, and formal technical decisions for major capital equipment. 
• Lead the design and development of custom heavy-duty mechanical systems, ensuring high reliability, maintainability, and performance in continuous industrial operations. 
• Lead the design and integration of complex rotary components (shafts, bearings, seals, couplings, gears, lubrication systems). 
• Oversee detailed CAD models, drawings, GD&T, weldment designs, and manufacturing documentation for large equipment systems. 
• Conduct and review advanced analyses (FEA, CFD, fatigue, vibration, thermal, dynamic analysis) to validate and optimize machine performance. 
• Evaluate and qualify components, materials, and suppliers for robust long-term service. 
• Perform and guide advanced structural and fatigue analysis for large, welded assemblies, pressure boundaries, frames, housings, and mechanical support structures. 
• Assess degradation mechanisms (corrosion, fatigue, creep, wear, cracking) and develop strategies to prevent failures. 
• Ensure all designs and reviews meet ASME, AWS, AISC, API, and internal standards. 
• Support systems through the complete lifecycle — from concept development and prototyping through manufacturing, commissioning, field support, and end-of-life evaluation. 
• Lead root cause analyses for equipment failures; drive corrective actions and design improvements that minimize downtime and improve total lifecycle cost. 
• Collaborate closely with manufacturing, automation, controls, operations, and maintenance to ensure systems are safe, serviceable, and cost-effective. 
• Mentor and elevate the technical capabilities of mechanical, structural, and rotational equipment engineers across the organization. 
• Translate complex engineering concepts to non-technical stakeholders, ensuring clarity and alignment across teams. 

This position allows for growth and career progression to be determined by performance, certifications, and supervisor discretion.  

BENEFITS

•  401(k) with employer matching 
•  Generous paid time off and paid holidays (plus 2 floating holidays to use your way) 
• Disability, Life, and AD&D Insurance  
• FSA and HSA options with employer contributions  
•  Tuition reimbursement — we invest in your growth 
• Casual work attire — no suits required (unless that’s your thing) 
• Remote flexibility  

EDUCATION/EXPERIENCE  

• Bachelor’s degree in mechanical engineering, structural engineering, or related discipline (advanced degree strongly preferred) 
• 20+ years of experience in industrial machine design, rotating equipment engineering, structural/welded system design, or asset integrity engineering 
• Proven track record designing, analyzing, and supporting large industrial mechanical systems and welded structures in manufacturing, energy, processing, or similar heavy industries 
• Expert-level proficiency in CAD (NX preferred), FEA tools, and structural analysis platforms (ANSYS, ABAQUS, RISA/STAAD/SAP2000, etc.) 
• Deep knowledge of bolted joints, welded structures, GD&T, tolerance analysis, and tribology 
• Extensive hands-on experience with rotary systems including bearing selection, lubrication design, seal systems, alignment, rotor dynamics, and vibration analysis 
• Strong understanding of materials engineering and manufacturing methods for weldments, machined parts, and pressure-boundary systems 
• Thorough knowledge of ASME, AISC, API, ANSI, AWS, and other relevant industrial design standards 
• Excellent communication, documentation, and problem-solving skills 
• Minimum requirement for all positions is a high school diploma or GED 
• Must have effective verbal, reading, and written communication skills in the English language 

PREFERRED QUALIFICATONS 

• Master’s or PhD in mechanical engineering or related field 
• Professional Engineer (PE) license or equivalent high-level certification 
• Experience with condition monitoring, predictive maintenance, and vibration diagnostics 
• Field engineering experience with commissioning, testing, and troubleshooting large rotating or structural systems 
• Formal FFS (Fitness-for-Service) experience following API 579 or comparable methodologies 

ADDITIONAL INFORMATION 

• Compensation for this role is between $150,000 and $200,000 annually 
•  This role may qualify for a discretionary bonus, recognizing outstanding contributions to team and company success 
• This role requires 10% travel to support Sedron facilities 
•  In compliance with state and local pay transparency laws, the expected compensation for this role is shared above. The range provided is Sedron’s estimate of the base compensation for this role and the final offer will be based on job-related and non-discriminatory factors such as experience, skills, and geographic location.
