What is the work of a process engineer?

A process engineer designs, develops, and optimizes manufacturing processes to improve efficiency, quality, and safety. They analyze production workflows, troubleshoot issues, and implement improvements using tools like process flow diagrams and statistical analysis. Strong problem-solving skills and knowledge of industry standards are essential for this role.

What are some common challenges process engineers face when implementing process improvements, and how can they overcome them?

Process Engineers often encounter challenges such as resistance to change from team members, integrating new technologies with existing systems, and ensuring process changes meet regulatory standards. Overcoming these obstacles typically involves clear communication, involving stakeholders early in the process, thorough documentation, and piloting changes before full-scale implementation. Building strong cross-functional relationships and continuously gathering feedback also help ensure that improvements are effective and sustainable.

What is a process engineer?

Process Engineers are professionals who design, implement, and optimize industrial processes to improve efficiency, quality, and safety in manufacturing or production environments. They analyze workflows, troubleshoot process issues, and develop solutions to enhance productivity and reduce costs. Process Engineers often work in industries such as chemicals, pharmaceuticals, food and beverage, and energy, ensuring processes are compliant with environmental and safety regulations. Their work is vital for maintaining smooth operations and achieving organizational goals.

What jobs do process engineers do?

Process engineers design, develop, and optimize manufacturing processes to improve efficiency, safety, and quality. They analyze production data, troubleshoot issues, and implement process improvements using tools like process flow diagrams and statistical analysis. Their work often involves collaboration with production teams and requires knowledge of engineering principles and industry standards.

What are the key skills and qualifications needed to thrive as a process engineer, and why are they important?

To thrive as a Process Engineer, you need a solid background in chemical, mechanical, or industrial engineering, often supported by a relevant bachelor's degree and understanding of process optimization principles. Familiarity with process simulation software (such as Aspen Plus or AutoCAD), Six Sigma methodologies, and quality management systems is typically required. Strong analytical thinking, problem-solving abilities, and effective communication skills set candidates apart in this role. These skills and qualifications are essential to improve efficiency, ensure safety, and drive continuous improvement in industrial and manufacturing processes.

What is the difference between Process Engineer vs Manufacturing Engineer?

AspectProcess EngineerManufacturing Engineer
CredentialsBachelor's in Engineering, certifications like Six SigmaBachelor's in Engineering, certifications like Lean Manufacturing
Work EnvironmentDesigning and optimizing processes, R&D settingsOverseeing production lines, factory floors
Industry UsageManufacturing, chemical, aerospaceAutomotive, electronics, consumer goods

Process Engineers focus on designing and improving manufacturing processes, often working in R&D or engineering departments. Manufacturing Engineers concentrate on implementing and managing production on the factory floor. Both roles require similar technical skills and certifications but differ mainly in their scope and work environment.

Job description

ABOUT LUMILENS
At Lumilens we are building the critical photonics infrastructure that powers tomorrow's AI supercomputing. From chip-to-chip optical interconnects to scalable photonic engines, Lumilens is unlocking a new era of computing faster, cooler, and massively more efficient.
We're a well-funded startup backed by Mayfield and led by veterans who've built and scaled some of the most transformative technologies in the industry. This isn't incremental innovation, it's a ground-floor opportunity to rethink the optical layer from the silicon up. You'll work alongside a team of world-class engineers solving some of the hardest challenges in optics, systems, and scale. Every decision you make will directly influence how we build, source, and deliver the infrastructure of tomorrow.
If you're looking for mission, momentum, and the chance to make an outsized impact, jump on the rocket ship. We're just getting started.
The Role
As Generative AI continues to accelerate, the demands on data center infrastructure are shifting from individual chips to tightly integrated systems of chips. At Lumilens, our Photonic technology is redefining interconnect performance with dramatically higher bandwidth, better energy efficiency, and greater scalability. In this role, you will drive process development for novel III-V etching, coating, and related fabrication modules that enable next-generation photonic systems. You will translate product requirements into process requirements, define the tooling and metrology needed to execute, and institutionalize repeatable processes that can scale from development into manufacturing.
Responsibilities
  • Drive process development for novel III-V etching, coating, and related semiconductor fabrication modules in support of Lumilens' advanced photonics platform.
  • Translate product and device requirements into clear process requirements, specifications, control plans, and acceptance criteria.
  • Define process tooling needs, including equipment capability, process windows, fixturing, materials, and vendor requirements.
  • Design, execute, and manage DOEs to optimize etch profiles, coating performance, process repeatability, yield, and manufacturability.
  • Define metrology requirements, measurement methods, inspection strategy, and outsourcing approach for process development and qualification.
  • Evaluate and select tooling, vendors, and external partners based on technical capability, commercial considerations, scalability, and long-term process ownership.
  • Institutionalize new tools and processes through documentation, process flows, work instructions, engineering reports, and training materials.
  • Support assessment of silicon photonics processing flows, including process compatibility, integration risks, yield-limiting factors, and opportunities for improvement.
  • Collaborate with device, photonics, packaging, manufacturing, and external fab partners to troubleshoot process issues and drive corrective actions.

Guidelines
  • Senior-level experience in semiconductor process engineering, process development, or process integration, ideally with III-V materials, silicon photonics, compound semiconductors, or photonic devices.
  • Hands-on experience with wet or dry etching, coating, thin films, deposition, lithography, metrology, or related cleanroom fabrication processes.
  • Ability to define process requirements from product requirements and translate technical needs into executable process flows, specifications, and control plans.
  • Strong working knowledge of DOE design, process characterization, statistical analysis, capability studies, and data-driven process optimization.
  • Experience defining metrology methods and working with internal or outsourced metrology resources such as SEM, profilometry, ellipsometry, optical inspection, or similar techniques.
  • Demonstrated ability to evaluate, select, and qualify tooling based on process performance, vendor capability, cost, schedule, serviceability, and scalability.
  • Experience documenting and institutionalizing new processes, including process flows, recipes, work instructions, qualification reports, and lessons learned.
  • Familiarity with silicon photonics processing, heterogeneous integration, or III-V to SiPh process interfaces is highly valuable.
  • Strong problem-solving, communication, and cross-functional collaboration skills in a fast-paced development environment.

Why Join Us?
• Competitive salary commensurate with experience
• Comprehensive benefits package including health insurance
• Professional development opportunities and certification support
• Access to cutting-edge photonics and advanced manufacturing technologies
• Collaborative work environment with cross-functional teams solving complex challenges
Lumilens is an equal opportunity employer. All qualified applicants will receive consideration without regard to race, color, religion, gender, identity, orientation, veteran status, disability, or any other legally protected status.
