We're building safety-enhancing technology for aviation that will save lives. Automated aviation systems will enable a future where air transportation is safer, more convenient and fundamentally transformative to the way goods — and eventually people — move around the planet. We are a team of mission-driven engineers with experience across aerospace, robotics and self-driving cars working to make this future a reality.
As an Electrical System Integration Engineering Intern at Reliable Robotics, you will be a part of the System Integration Engineering team, reporting to the system integration engineering manager. This is a small team of highly motivated people designing, testing, and flying advanced electrical systems. We enjoy combining mechanical and electrical hardware and getting it onto an aircraft safely and quickly.
Responsibilities
In your role as a system integration intern, you will get to own a project through the planning, assembly, and testing phases of development. Our intention is for integration interns to get experience in system design as well as hands-on experience building and testing systems both in the lab and on our development aircraft. All of our intern projects are high priority and value-added efforts contributing to our automated flight systems.
Basic Success Criteria
Junior or Senior standing in 4-year college degree program in electrical engineering or equivalent practical experience
Solid understanding of electrical engineering fundamentals
Experience reading electrical wiring schematics
Experience testing electronic systems for proper performance
Experience writing and running code
Preferred Success Criteria
Hands on application of electronic systems through classes, clubs, or hobbies
Experience designing a system architecture and weighing design options to accomplish specific system requirements
Ability to design, build, and operate electrical test stands and equipment
Excellent measurement, technical writing, and data analysis skills
Eagerness to both teach and learn
This position requires access to information that is subject to U.S. export controls. An offer of employment will be contingent upon the applicant’s capacity to perform in compliance with U.S. export control laws.
All applicants are asked to provide documentation that legally establishes status as a U.S. person or non-U.S. person (and nationalities in the case of a non-U.S. person).

Systems Integration Engineer Jobs in California: Frequently Asked Questions
How do you become a systems integration engineer in California?
The most direct path is a bachelor's degree in electrical engineering, systems engineering, mechanical engineering, or computer science from an accredited California university, followed by a role in systems test, integration lab support, or a related engineering position. California does not require a state license for the systems integration engineer title, though many employers in aerospace and defense require candidates to hold or qualify for a Professional Engineer license issued by the California Board for Professional Engineers, Land Surveyors, and Geologists.
Which companies hire systems integration engineers in California?
Companies currently hiring systems integration engineers in California include Northrop Grumman, Apple, and Tesla, per current listings on Migrate Mate as of November 2026. California's concentration of aerospace primes, semiconductor firms, and defense contractors makes it one of the most active states for this role.
Which California cities have the most systems integration engineer jobs?
Palo Alto, El Segundo, and San Diego have the most systems integration engineer openings in California. The Los Angeles area is driven by the region's large aerospace and defense contractors, the Bay Area by semiconductor and enterprise technology employers, and San Diego by defense electronics and communications systems firms that have anchored engineering talent there for decades.
Are there remote systems integration engineer jobs in California?
Yes, but they're rare. Systems integration engineering is fundamentally a hands-on discipline that requires physical access to lab environments, test hardware, and integrated systems, which limits full-remote arrangements. About 44% of systems integration engineer openings tied to California are remote or hybrid as of November 2026, and those positions typically cover the requirements-definition, documentation, and architecture phases rather than bench-level integration and test work.
How can I get hired as a systems integration engineer in California with little or no experience?
The most realistic entry path is a systems test engineer or integration technician role, which gives hands-on lab exposure without requiring full independent ownership of integration programs. Large California defense and aerospace employers such as Northrop Grumman and Lockheed Martin run structured new-graduate rotational engineering programs at their Southern California facilities. Completing a senior capstone project that involves hardware-software integration, earning a Certified Systems Engineering Professional associate credential, or building a portfolio that demonstrates requirements traceability and interface documentation gives early-career candidates a concrete edge in California interviews.
Where can I find and apply to systems integration engineer jobs in California?
You can find and apply to systems integration engineer jobs in California on Migrate Mate, which lists current California openings across aerospace, defense, semiconductor, and technology employers. Search the listings to find roles that fit your background, experience level, and preferred location, then apply directly to the ones that match.
