Instrumentation & Controls Engineer III-Ground Systems

## About the Role Join Firefly's Ground Systems team as a Level III Instrumentation & Controls Engineer and become the technical authority for the systems that make launch, orbit, and landing possible.

This isn't theoretical engineering - it's expert-level design, technical leadership, and strategic direction for the control systems and instrumentation that monitor rocket engines, manage cryogenic propellants, and enable rapid-fire test campaigns across all of Firefly’s programs. As a Level III engineer, you are the subject matter expert and technical leader.

You'll architect complete control system solutions from concept through commissioning, lead complex projects and multiple engineers on time-sensitive initiatives, and serve as the go-to authority when the toughest technical challenges arise. Your control architectures will span all of Firefly's test stands, test fixtures, and launch sites.

Your technical decisions will influence and shape the evolution of rapidly evolving launch and in-space programs. Your expertise will guide the next generation of engineers developing Firefly's ground infrastructure. This role demands technical mastery and leadership.

You'll need deep expertise in PLCs, HMIs, data acquisition, and instrumentation - but also the strategic vision to set technical direction, the leadership skills to guide project teams, and the business acumen to support project execution and customer engagement.

You'll work at the highest technical level - defining standards, driving innovation, developing roadmaps, and representing Firefly's I&C capabilities to internal and external stakeholders. You'll lead technical teams through the most complex challenges, make architectural decisions that impact multiple programs, and resolve problems that other engineers escalate to you.

When a novel test requirement demands a control solution that doesn't exist yet, you'll architect it. When a major customer has concerns about data integrity or performance, you'll be in the room explaining our approach. When a critical project needs expert leadership to stay on track, you'll take the reins.

If you're a recognized expert in instrumentation and controls who's ready to shape the technical direction of a growing space company, mentor the next generation of engineers, and see your architectural vision enable humanity's expansion into space, this is your opportunity. ## Technical Leadership & Subject Matter Expertise -
