Who's Hiring
What Indiana Employers Look For
The qualifications that appear most often in principal engineer jobs across Indiana.
- Bachelor's degree in engineering from an ABET-accredited program required
- Professional Engineer license issued or recognized by the Indiana Professional Licensing Agency preferred for senior roles
- Eight or more years of progressive engineering experience in a relevant discipline
- Demonstrated ability to lead cross-functional technical teams and define system architecture
- Deep expertise in one or more of mechanical, electrical, embedded software, or systems engineering
- Experience working within regulated industries such as medical devices, defense, or automotive manufacturing
Principal Engineer Jobs in Indiana: Frequently Asked Questions
How do you become a principal engineer in Indiana?
Most Indiana employers expect a bachelor's degree in engineering from an ABET-accredited institution, followed by a decade or more of progressively complex technical work. For roles in civil, structural, or public infrastructure, the Indiana Professional Licensing Agency administers the Professional Engineer license, which typically requires passing the FE and PE exams. In private-sector manufacturing, defense, and tech, licensure is often preferred but not required, and depth of systems or domain expertise matters most.
Which companies hire principal engineers in Indiana?
Companies currently hiring principal engineers in Indiana include Eli Lilly, BAE Systems USA, and Collins Aerospace, per current listings on Migrate Mate as of November 2026. Indiana's concentration of advanced manufacturing, life sciences, and defense contractors means hiring activity is particularly steady among large industrial and technology employers anchored in the Indianapolis metro and northeast Indiana.
Which Indiana cities have the most principal engineer jobs?
Indianapolis, Fort Wayne, and Lebanon lead Indiana for principal engineer openings. Indianapolis dominates because it is home to major life sciences, defense, and technology employers, while Fort Wayne and other metros contribute through long-established manufacturing and automotive supply chain operations that require senior technical leadership at the plant and engineering center level.
Are there remote principal engineer jobs in Indiana?
Yes, but they are less common than in purely software-focused fields. About 44% of principal engineer openings tied to Indiana are remote or hybrid as of November 2026, reflecting the hands-on nature of much of the state's manufacturing, defense, and hardware engineering work. The roles most likely to offer remote flexibility are those focused on software architecture, systems integration, or program management rather than lab or plant floor work.
How can I get hired as a principal engineer in Indiana with little or no experience?
The most realistic path is through an entry-level or associate engineer role at one of Indiana's large industrial or technology employers. Companies like Cummins, Eli Lilly, and Raytheon regularly run new-graduate and rotational engineering programs in Indiana that give early-career engineers exposure across disciplines. Earning the Fundamentals of Engineering credential through the Indiana Professional Licensing Agency, building a project portfolio, or moving laterally from a senior engineer or lead technician role are the most effective ways to position for a principal-level promotion over time.
Where can I find and apply to principal engineer jobs in Indiana?
You can find and apply to principal engineer jobs in Indiana on Migrate Mate, which lists current Indiana openings in one place. Search the roles available, find the ones that match your background and target location, and apply directly through each listing.
