What does a senior process engineer do?

A Senior Process Engineer is responsible for designing, optimizing, and overseeing processes within manufacturing or production environments. They analyze workflows, troubleshoot issues, and implement improvements to increase efficiency, safety, and product quality. Senior Process Engineers often lead projects, mentor junior engineers, and collaborate with cross-functional teams to ensure operational excellence. Their expertise is vital in industries like chemicals, pharmaceuticals, oil and gas, and food processing.

What are the key skills and qualifications needed to thrive as a senior process engineer?

To thrive as a Senior Process Engineer, you need a strong background in chemical or process engineering, problem-solving skills, and typically a bachelor's or master's degree in a relevant field. Expertise in process simulation software (such as Aspen Plus or HYSYS), Six Sigma or Lean certifications, and familiarity with process control systems are highly valued. Outstanding analytical abilities, leadership, and effective communication set top performers apart in this role. These skills and qualifications are crucial for optimizing processes, ensuring safety and compliance, and leading teams to achieve operational excellence.

What are some common challenges senior process engineers face when working on cross-functional teams?

Senior Process Engineers often collaborate with professionals from various departments, such as operations, quality, and maintenance. A common challenge is aligning diverse priorities and communication styles to achieve shared project goals. Successfully managing these differences requires strong interpersonal and project management skills, as well as the ability to translate technical concepts for non-engineering colleagues. Regular meetings and clear documentation can help ensure everyone stays informed and engaged throughout the process.

What is the difference between Senior Process Engineer vs Process Engineer?

AspectSenior Process EngineerProcess Engineer
QualificationsBachelor's or Master's in Engineering, often with 5+ years experienceBachelor's degree in Engineering or related field, typically 1-3 years experience
ResponsibilitiesLeading process improvements, mentoring, project managementSupporting process development, data analysis, assisting senior staff
Work EnvironmentDesign teams, manufacturing plants, R&D departmentsManufacturing facilities, engineering teams, operational support

Senior Process Engineers typically have more experience, leadership duties, and oversee complex projects, while Process Engineers focus on supporting process development and implementation. Both roles are essential in manufacturing and engineering industries, but the senior role involves greater responsibility and strategic planning.

How much does a senior process engineer earn?

A senior process engineer typically earns between $80,000 and $130,000 annually, depending on experience, industry, and location. They often have specialized skills in process optimization, project management, and may hold certifications like Six Sigma or PE licensure.

Job description

SENIOR PROCESS ENGINEER

Mesh Optical Technologies was founded on the belief that optical photons will be at the center of advanced technologies in the coming century. Making advanced technology ubiquitous means building at scale, and that's exactly what we're doing at Mesh.

Our products require semiconductor-grade packaging processes-bumping, dicing, precision bonding, optical alignment, and automated assembly-executed at yield levels and volumes that demand real process engineering discipline. We are seeking a Senior Process Engineer to own the development and qualification of these processes from R&D through production ramp, and to help build high-volume semiconductor packaging process engineering in the US.

RESPONSIBILITIES

  • Own development of wafer prep and die-level packaging processes: bumping, dicing, sub-micron precision bonding, sub-micron optical alignment, flip-chip die bonding, wire-bonding, dispense, fully-automated final assembly and associated materials
  • Own tool selection, materials selection, recipe development, and statistical process control limits to transfer processes from R&D to volume production
  • Translate package and product designs into high volume production processes and collaborate with electrical, mechanical, and photonic circuit design teams to design-for-manufacturing
  • Design production processes from the lab bench through proof of concept and production ramp
  • Establish process limits and feedback process constraints as design rules to design teams
  • Characterize parts with x-ray, FIB cut/SEM, CSAM, and die shear testing, closing the loop with electrical, mechanical, and photonic circuit design teams
  • Act as the technical owner for failure-analysis findings, root cause analysis, and corrective actions
  • Push process yields above 99.9% and thermal-cycle reliability for years-long qualification
  • Provide technical mentorship as we work to build up high-volume semiconductor packaging process engineering in the US

QUALIFICATIONS

  • MS or PhD in Materials Science, Chemical Engineering, Electrical Engineering, or similar
  • Extensive (MS + 2 years) hands-on semiconductor process-development experience
  • Strong troubleshooting skills and hands-on experience in semiconductor packaging, assembly, or advanced manufacturing environments
  • Demonstrated success qualifying processes such as flip-chip bonding, wafer processing, plasma cleaning, and wire bonding
  • Expertise in statistical quality control and process improvement methodologies, with experience leading internal audits and driving continuous improvement
  • Comfortable working in a cleanroom or controlled manufacturing environment with cross-functional engineering teams
  • Willingness to work extended hours and weekends as needed

PREFERRED EXPERIENCE

  • 5+ years of fab or wafer level packaging experience (e.g. lithography, etch, CVD, CMP, solder bumping, wafer dicing)
  • Experience integrating photonic devices into complex opto-electronic packages, sub-m die-bonding, wafer prep, and materials used in advanced packaging

COMPENSATION AND BENEFITS:

Pay range: 
Senior Process Engineer: $140,000.00 - $180,000.00/per year

Title and base salary are determined on a case by case basis commensurate with experience and merit.

In addition to base salary, compensation for this role includes:

  • Eligibility for long-term incentives including company stock options and discretionary bonuses awarded for exceptional achievements.
  • Comprehensive medical, vision, and dental insurance with significant cost covered by the company for yourself and dependents.
  • Paid parental leave and flexible PTO (3 weeks accrued vacation and 10 company holidays per year).
  • 401(k) retirement plan access.
  • Relocation assistance to sunny Los Angeles.
