Job Description

JOB OBJECTIVE:  Design, develop, and test electronic systems for high performance analytical instrumentation.


1. Key contributor on cross-functional engineering teams (internal and external) consisting of optical, electrical, software, mechanical, manufacturing, and quality engineers to achieve project deliverables.

2. Design, develop, construct, test, and transfer to manufacturing the electronic and electrical portions of complex analytical instruments. These instruments typically include optical sources and detectors, multi-axis motion control, temperature controls, power supplies, electronics, software, and user interface.

3. Responsible for the complete development cycle for system electronics: defining overall electronic architecture, developing the electronic schematics, selecting components, designing circuit board layouts (either by self or directing others), prototyping, testing, and documenting for production release.

4. Responsible for insuring that instruments meet applicable regulatory requirements including, for example, CE, UL, IEC, and RoHS.

5. The incumbent will have broad responsibility for electronic design, both analog and digital, and may also be responsible for firmware programming.

6. Collaborate closely with optical engineers, particularly on light sources and light detection.

7. Collaborate closely with mechanical engineers, particularly in the areas of motion control electronics and electronic packaging and cooling.

8. Use calculation tools for electronic circuit design and optimization. Where appropriate, apply software simulation tools for circuit analysis and optimization.

9. Use current best-practice tools, design methods, and production approaches. Remain current in technology through self-directed reading, training, trade shows, and networking.

10. Perform hands-on work with electronic components and systems. Personally perform construction and test of prototypes and/or supervise technicians doing this work.

11. Provide clear organized documentation to be used by other engineers, production, suppliers, consultants, and regulatory agencies. Prepare and present work at design reviews.

12. Transfer electronic designs to production. Where appropriate, develop production test methods and test equipment for use internally and/or by external contract circuit board manufacturers.

13. Collaborate with scientists, product management, industrial designers, and others to understand user needs and address those needs in designs.

14. Use analytical and troubleshooting skills to address instrumentation systems issues. Conduct root cause failure analysis to improve instrument performance and reliability. Perform detailed technical analyses and create test and analysis reports.

15. Understand and comply with ethical, legal and regulatory requirements applicable to our business.


1. Support production in the manufacture of instruments.

2. Support preparation of proposals, project plans, and cost estimates.


1. BS in Electrical Engineering.

2. Minimum of 6 years industry experience developing electronic products.

3. Highly proficient with schematic entry and board layout software tools. Experience with Altium software is preferred, though other software tools such as OrCAD or Mentor Graphics are acceptable.


4. Analog circuit design experience including sensitive measurement circuitry, analog signal conditioning and AD conversion, LED drivers, motor drivers, and power supplies.

5. Digital circuit design including motion control, FPGA, digital communication, and microprocessor circuits.

6. Ability to work in a diverse team environment with excellent interpersonal, communication and team-based management skills.

7. Experience in development of new and unique electronic instrumentation for scientific applications or other complex electronic systems.


8. Electronics manufacturing process knowledge, including surface mount, thru-hole, flex circuit, and production testing.

9. Knowledge of regulations such as CE, UL, IEC, and RoHS. Strong understanding of design to meet EMI and EMC regulations.


1. Basic knowledge of optical systems is desirable, particularly light sensors, imaging cameras, and their associated electronics.

2. Experience with low-noise electronics for low-light detectors such as PMTs and avalanche photo diodes is highly preferred.


3. Experience with electronics for driving LEDs, lasers, and laser diodes is highly preferred.

4. Basic knowledge of mechanical engineering is desirable, particularly heat transfer as related to electronics.

5. Familiarity with SAP is desirable.


1. May occasionally lift up to 40 lbs.

2. Ability to work in a production environment around automated equipment.

3. Ability to work in an office environment utilizing a computer workstation.

4. Ability to work in a lab environment with chemical and biological materials.

5. Ability to travel by car or airplane, for one or several days, to suppliers, customers, training, and trade shows.
