As an engineering intern, you are expected to embody them in every design decision, debugging session, and team interaction: • Lead with Curiosity: Approach every system with a desire to understand not just how it works, but why it was designed that way. Ask questions early and often of your mentor, your teammates, and yourself. The best engineers are the ones who never stop learning. • Own the Outcome: Take genuine ownership of your work, from first prototype through final validation. Communicate blockers early, document your work thoroughly, and follow through on what you commit to. • Build the Right Thing: Understand the customer need behind each technical requirement and make design decisions that are practical, reliable, and built to last. Good engineering solves the real problem, not just the interesting one. • Empower Others: Contribute to a team culture where knowledge is shared freely. Ask for feedback, act on it, and share what you learn with those around you. Your curiosity and fresh perspectives will make the whole team better. About SOE: SOE is an engineering consulting firm that specializes in electrical, electromechanical, and embedded systems. Founded in 2016, we’ve grown from a 3-person operation to a team of 25+ engineers across offices in El Segundo, CA and Redmond, WA. In that time, we’ve completed over 250 projects for more than 100 clients. 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 are weapons. We’re 100% employee-owned, which means that every engineer at SOE has a real stake in what we build. We structured the company this way because we believe the people best equipped to advance our mission are the ones doing the work. We approach problems from first principles. We break challenges down to their most fundamental components, which is how we find solutions that hold up across industries, use cases, and engineering functions. We focus on solving the right problems and building the teams to take them on.
