Position Summary: The Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) seeks an Electrical Engineer to join a dynamic team working on the development of observing systems and experimental approaches coupling advances in electronics, laser, optics and software design with key unanswered questions related to the Earth's changing climate structure. The Electrical Engineer will be involved in analog-digital electronics design for a new generation of instrument development at the intersection of photonics, robotics and instrument design. Our groups include senior and junior engineers, senior scientists, post-doctoral fellows, and graduate students, overseen by three faculty members. Our team's sensor experience stretches back decades, with flight altitudes ranging from 10 feet for 120,000 feet, stretching from Punta Arenas, Argentina, to Utqiaġvik, Alaska, and from Guam to San Pietro Capofiume, Italy. All these efforts are united by a drive to make ground-breaking measurements in demanding environments to deepen our understanding of atmospheric chemistry's impact on climate.

This is a one-year term appointment, with the possibility of renewal.
Duties & Responsibilities: The Electrical Engineer will work on conceptualization, design, fabrication, testing and analysis of atmospheric research instruments, subsystems, and lab instrumentation and equipment; collaborating with a multi-disciplinary science and engineering team. These instruments demand closely integrated analog/digital electronics, optical/mechanical designs, and software system development.
Typical Duties include:
Designs, builds, and documents data acquisition and control electronics, as well as power systems that are near space capable, have high reliability, and minimize size/weight/power consumption and risk. Reference-based measurements, noise control, and circuit stability are all factors considered to generate the most accurate and precise measurements possible. Some recent examples include:
A new, fully redundant 9.0kWh battery system for the first near space usage of LiNiMnCo batteries with full power and health monitoring, and remote control
A scalable, 3-channel, 100MHz, 16-bit, digitizing system with embedded DSP for in-flight detector high-speed data acquisition, filtering, and processing
A two-stage, transconductance preamplifier system for fast infrared detectors, with 1MHz bandwidth, sub 10nV/√Hz total noise, anti-aliasing filter, and differential output.
Determines design approaches and parameters to meet scientific requirements. Refines specifications by translating general parameters into specific quantitative design metrics.
Troubleshoots instrument failures both in the lab and after flight. Work is often performed under extreme pressure while in the field, and instruments are essential for the success of the mission.
Provides students and science staff with electronic engineering services to address any instrument and laboratory setup requirements. These tasks often end up being prototypes for final instrument board designs.
Provides instruction to students and staff with instrument operation and maintenance. Mentors students in design and development techniques and procedures.
SEAS is not able to provide visa sponsorship for this position.
Commitment to Diversity: SEAS is dedicated to building a diverse community of individuals who are committed to contributing to an inclusive environment. Some of our core values include respect for all, serving the greater good, and welcoming individuals from diverse backgrounds, experiences, and perspectives. Many SEAS employees are eligible for Flexible Work Arrangements, which may be explored during the interview process. The Harvard John A. Paulson School of Engineering and Applied Sciences serves as the connector and integrator of Harvard's teaching and research efforts in engineering, applied sciences, and technology. Our core tenets are: educating broad-minded students; interdisciplinary research; integration across disciplines; and balancing theory, experimentation and practice to create an unmatched environment for learning and exploration. Through collaboration with researchers from all parts of Harvard, other universities, and industry, we bring discovery and innovation directly to bear on improving human life and society.
