Sr. Opto-Mechanical Engineer

Sr. Opto-Mechanical Engineer

At Endress+Hauser, progress happens by working together. As the global leader in measurement instrumentation, our ~17,000 employees shape the future in the field of process automation. Whether developing and realizing new technology as a team, collaborating to build instrumentation, or strengthening vital relationships with countless global industries, we work to create trusted relationships that help everyone thrive. As a family-owned company, we look beyond short-term moves and work to create a vision that is forward-thinking for our people, our clients, and the world at large.

We are looking for a Sr. Opto-Mechanical Engineer to join Endress+Hauser Optical Analysis, the global leader in Raman spectroscopy, tunable diode laser absorption spectroscopy (TDLAS), and quenched fluorescence (QF) instrumentation for laboratory, process, and manufacturing environments. Our laser-based analyzer systems perform high-performance chemical composition and concentration measurement of all phases of matter in any installation environment.

What is the role about?

We are seeking an experienced Sr. Opto-Mechanical Engineer with a strong background in both mechanical and optical engineering to support the design and development of Tunable Diode Laser Absorption Spectroscopy (TDLAS) analyzers and related systems. You'll work as part of our opto/mechanical engineering team to design precision assemblies, contribute to system integration, and support hands-on prototyping and testing. A working knowledge of electronics and instrumentation integration is important, as this role involves close coordination with electrical and optical engineers to bring complete systems together.

Which tasks will you perform?

• Design and Development:
  • Design opto-mechanical parts and assemblies for use in TDLAS gas analyzers and sample conditioning systems.
  • Create robust, manufacturable designs that balance performance, cost, and assembly complexity.
  • Lead mechanical design of subsystems with attention to alignment, thermal stability, and ease of integration.
  • Select materials and processes suited to harsh industrial environments, including stainless steel and aluminum alloys.
  • Perform mechanical stack-up and tolerance analysis to ensure performance under worst-case conditions.
  • Use simulation tools (thermal, structural, optical) to inform design decisions.
  • Build, assemble, and test prototypes to evaluate form, fit, function, and integration.
  • Own system-level integration of optical, mechanical, and electronic components, including commercial parts.
• Technical Drawings and Documentation
  • Generate and maintain accurate fabrication and assembly drawings, BoMs, inspection documents, and work instructions.
  • Apply GD&T to support both design intent and manufacturing inspection.
  • Own engineering documentation processes including change orders and release packages.
• Project Collaboration and Support
  • Work closely with optical engineers, electrical engineers, and manufacturing teams to develop and refine complete systems.
  • Collaborate with manufacturing and industrialization teams to transition designs into production.
  • Troubleshoot issues in current and legacy products, particularly around mechanical performance, optical alignment, and thermal behavior.
  • Provide input on manufacturability, serviceability, and cost during all phases of development.

The duties above describe the general nature and level of work being performed in this job. They are not intended to be an exhaustive list of all duties; additional responsibilities may be assigned, as required, by management.

What do we expect from you?

• Minimum of 7 years of experience in precision optical and mechanical instrumentation design.
• Expert-level proficiency in CAD (SolidWorks preferred); able to take design from concept to detailed drawing.
• Hands-on prototyping and system integration experience.
• Strong understanding of machining, sheet metal, and 3D printing processes.
• Solid grasp of GD&T and tolerance stack-up analysis.
• Familiar with structural, thermal, and basic optical simulation tools (SolidWorks Simulation, Ansys, Zemax OpticStudio).
• Effective at documenting and communicating design intent clearly and consistently.
• Able to work independently and collaborate in cross-functional teams.

• Experience designing for and working with industrial lasers, optics, and detectors.
• Familiarity with electrical/electronic components at the system integration level.
• Experience working with ERP/PLM systems (Syteline, Agile) and PDM tools (SolidWorks PDM).
• Familiarity with hazardous area equipment design and certification.
• Experience using CMMs and interpreting metrology results.

What can you expect from us?

• Family-owned, highly committed global company with a sustainable vision of the future.
• Lifelong learning encouraged by versatile training, tuition reimbursement, and further education opportunities.
• Comprehensive benefit package (to include medical, dental, vision) and 401(k) savings with company match.
• Compensation is competitive and includes bonus opportunities.
• Work-life balance encouraged through our 10 company-paid holidays, paid time off, paid parental leave, and employee assistance programs (financial, mental, and physical health and wellbeing).
• Employees work in a safety-first, climate controlled, clean manufacturing facility with utilization of Lean practices and ergonomic workstations to enhance productivity and comfort.

The listed annual salary range for this position is $120,000 - $140,000 but the actual package offered may vary depending on different factors, including market location, job-related knowledge, skills, and experience. The total compensation for this position would include other elements which include an annual nondiscretionary bonus.
