We believe that science and innovation have great potential to improve the world around us and are committed to advancing photonics (i.e., light-based) technologies that positively impact our customers, employees, and communities. Via educational outreach and more sustainable business practices, we continuously invest in a brighter future.

We recognize that each of our employees is a unique individual with the ability to contribute to our success and seek to find great people who will thrive in our fun, fast-paced culture.

Thorlabs is looking for an experienced Electrical Engineer to join our dynamic team at the Colorado Center for Innovation (CCI). Electrical Engineer II will serve as a technical lead within the CCI, driving the architecture and development of next-generation laboratory electronic products. You will take ownership of the full product lifecycle—from initial concept and complex circuit design to final compliance and manufacturing release.

This role requires a seasoned engineer capable of solving sophisticated hardware challenges in low-noise instrumentation and quantum photonics, while providing technical oversight to junior staff.

• Lead the design and schematic capture of high-precision analog and digital systems, ensuring optimal signal integrity for low-noise applications.
• Independently manage PCB layout strategies for complex, multi-layer boards involving high-speed signals, sensitive photonics interfaces, and varied power systems.
• Lead root-cause analysis for complex system failures and implement long-term design fixes.
• Coordinate with mechanical, software, and photonics engineers to define system requirements and ensure seamless cross-disciplinary integration.
• Oversee and guarantee that all products meet rigorous international standards (EMC/EMI, UL, CE) through comprehensive validation planning.
• Act as a technical resource and provide oversight for early-career engineers, conducting design reviews and promoting engineering best practices.

• Experience:
  
  5–10 years of professional experience specifically in precision analog design or high-performance instrumentation.
• Education:
  
  BSEE or MSEE or similar from an ABET accredited institution.
• Demonstrated equivalent knowledge and experience.

• Proficiency in EDA tools (including multi-layer stack-up and high-speed routing) and advanced SPICE/LTspice modeling for noise floor estimation, thermal behavior, and part tolerancing. Altium Designer is preferred.
• Hands-on experience performing advanced measurements of electronics (e.g., 1GHz+ oscilloscopes, spectrum analyzers, vector network analyzers) and characterizing low-level signals.
• Deep understanding of the design considerations for precision analog design (pico-ampere sensing, low-drift op-amps), high-efficiency power conversion, and high-speed digital integration.
• Familiarity with embedded digital electronics including: microprocessors, microcontrollers, programmable logic devices, volatile and non-volatile memories, Ethernet, I2C, SPI, UART and USB.
• Proven ability to author comprehensive Design Specifications, Test Plans, and Manufacturing Instructions; experienced in Design for Excellence (DFX)—specifically for manufacturability and test (DFM/DFT).
• Demonstrated success in contributing to cross-functional teams moving products from initial concept through New Product Introduction (NPI) and into low-volume/high-complexity production environments.
• Proficiency in advanced electronics rework, including fine-pitch SMT soldering and BGA troubleshooting, to facilitate rapid internal prototyping and failure analysis.
• Experience managing Signal Integrity (SI) and Power Integrity (PI) in sensitive analog-digital hybrid systems to minimize cross-talk and EMI.
• Architecting automated test environments using Python, LabVIEW, or C/C++ to streamline device characterization and production validation.
• A proven track record in photonics, laser control electronics, or precision measurement instrumentation,…
