Company Overview: Second Order Effects (SOE) is an engineering consulting firm that transforms uncertainty into fully functional hardware and software. We work on projects at all stages of development; we perform analysis, build prototypes, and take products to market. Our team solves high-impact problems across numerous industries, including automotive, aerospace, consumer electronics, industrial automation, biomedical, and green energy. Our designs control rocket engines, manage satellite communications, instrument fusion reactors, and are enjoyed by consumers around the world. The only thing we won’t build is weapons. Founded in 2016, Second Order Effects has 50+ employees (and counting!) in offices in El Segundo, California and Redmond, Washington. Weve worked with &gt;130 clients on &gt; 300 projects as a partner, on retainer, or on demand. How do we do this? We empower others, build the right thing, lead with curiosity, and own the outcome.

Team Overview: Mechanical engineering at SOE is a growth discipline but still rooted in the pioneering spirit that has driven us from the start. From our early innovations like RF combiners featuring custom copper-tungsten elements and phased-array speakers in acoustically-optimized enclosures, the close coupling between electrical and mechanical design persists as a cornerstone of our company. As our projects become more ambitious and complex, our mechanical engineering team continues to rise to the challenge. Being part of the mechanical engineering team is an opportunity to contribute to a dynamic, growth focused environment, where we thrive on collaboration, interdisciplinary learning, continuous personal and professional development. We take ownership of our work and support one another through that growth. We look forward to welcoming you to the team!
