Senior Electrical Engineer

Senior Electrical Engineer

Aeris Technologies, Inc., a subsidiary of Project Canary, develops and commercializes advanced, laser-based gas analyzers for trace gas monitoring across environmental, industrial, laboratory, and field applications. Aeris instruments deliver high-precision, real-time measurements of greenhouse gases, atmospheric pollutants, and natural gas leak indicators, helping customers collect reliable data in fixed, mobile, handheld, and aerial configurations. As part of Project Canary, Aeris supports a broader climate technology platform that helps energy companies improve and report on their emissions footprint. Project Canary combines high-fidelity sensors, data from multiple technologies and sources, and proprietary analytics to deliver actionable insights that help operators stop leaks faster, reduce risk, streamline reporting, and differentiate their operations for key stakeholders. Aeris's technology brings lab-grade gas sensing performance into the field, supporting applications in environmental monitoring, industrial safety, air quality, research, and emissions measurement.

The Senior Electrical Engineer will join the Engineering team at Aeris Technologies, based out of our office in Hayward, CA. This role will focus on the electrical design and development of our next generation of high-precision, ultra-sensitive trace gas analyzers. The ideal candidate will have experience designing electronics for laser-based gas spectroscopy systems, with a deep understanding of MIR/NIR lasers, optical detection chains, and the exceptional signal fidelity required for trace gas measurement. Working closely with cross-functional engineering teams, this person will own the electrical architecture from concept through production, helping drive new product development and continuous improvement of existing systems. We're looking for an engineer who enjoys solving difficult technical problems and is energized by building products that move from concept into production. The ideal candidate combines deep technical expertise with curiosity, collaboration, and a practical approach to engineering, helping turn complex optical systems into reliable products that customers depend on.

Key Responsibilities

• Design, build, debug, and validate the electronics for next-generation laser-based gas analyzers.
• Lead the design and development of high-precision electrical systems, including analog front-ends for photodetectors, laser driver circuits, high-ENOB ADC/DAC chains, and high-speed communications.
• Select and integrate components for ultra-sensitive trace gas analyzers used in production environments.
• Drive circuit modeling, simulation, prototyping, and validation against demanding noise, stability, and precision requirements.
• Lead the PCB lifecycle from architecture and layout through production and continuous product improvement.
• Explore and evaluate emerging lasers, detection approaches, and signal processing techniques to improve analyzer performance.
• Partner closely with software, mechanical engineering, manufacturing, sales, and operations to bring new products from concept to production and continuously improve existing systems.
• Mentor engineers as the team grows while remaining actively engaged in hands-on design and development.

Skills, Knowledge and Expertise

Required Qualifications:

• Bachelor's degree in Electrical Engineering or a related field. Advanced degree is a plus.
• 7+ years of electrical engineering experience with a strong focus on analog circuit design, signal processing, and system integration.
• Experience designing electronics for laser-based spectroscopy or closely related optical sensing systems.
• Experience working with MIR/NIR lasers, optical detection chains, and precision low-noise analog circuitry.
• Direct professional experience with laser-based gas spectroscopy or optical gas sensing instruments is strongly preferred. Candidates with deep analog/RF design experience in other high-precision optical or scientific instrumentation will also be considered.
• Demonstrated ability to ramp quickly in active hardware development environments and contribute to production-ready designs early in the development cycle.
• Proven experience leading engineering teams, driving R&D projects into production, and managing complex, technically demanding projects.
• Strong knowledge of analog and mixed-signal electronics, including signal conditioning and processing for high-precision optical and laser-based measurement systems.
• Proficiency with PCB design tools and circuit simulation software, such as OrCAD and LTspice.
• Experience with embedded systems, microcontroller programming, and serial communication protocols (UART, I2C, SPI). Familiarity with high-level scripting languages such as Python is also preferred.
• Proficiency with laboratory test equipment, including oscilloscopes, logic analyzers, function generators, power supplies, high-precision digital multimeters (DMMs), and data loggers.
• Demonstrated ability to balance technical rigor with practical execution, making sound engineering decisions that move products toward production.

Nice to Have:

• Demonstrated track record of shipping products to production, beyond prototypes or laboratory demonstrations.
• Hands-on experience with MIR lasers and laser diode driver circuits.
• Experience designing photodetector front ends, including transimpedance amplifiers, lock-in detection, or similar architectures.
• Knowledge of C/C++ and Linux operating systems.
• Familiarity with power management and battery charging systems.
• Familiarity with electronics regulatory compliance standards, including UL and CE.
