About The Position

Castelion is hiring Avionics Hardware Engineers to own flight-critical electronics across design, bring-up, test, and integration. The role is intended for engineers experienced with complex electronic systems who can take responsibility for avionics subsystems and work effectively in a high-tempo development environment. Engineers may own areas such as motor controllers, avionics backplanes, power distribution, or outward-facing avionics test and integration.

The engineer will guide hardware from architecture and schematic design through PCB layout, bring-up, and production support. The role includes making design decisions, leading debugging and validation, collaborating across functions, documenting technical work, and partnering with manufacturing and suppliers to transition prototypes to production. Designs are continually improved based on test results, field data, and changing requirements.

The position may require access to classified information or restricted U.S. Government sites, systems, or information. If designated, employment may depend on obtaining and maintaining required government clearance or authorization and satisfying applicable citizenship or other eligibility requirements. The position also requires access to export-controlled information without additional export licensing being required.

Requirements

• Bachelor's degree in electrical engineering or a related field.
• Proven end-to-end ownership of avionics or high-reliability electronic hardware.
• Strong experience with PCB design, bring-up, and lab debugging.
• Ability to operate autonomously and drive hardware issues to closure.
• Ability to access applicable export-controlled information without additional export licensing being required.

Nice To Haves

• Avionics, aerospace, missile, space, automotive, or defense hardware experience.
• Experience with motor controllers, backplanes, power electronics, or flight hardware.
• Familiarity with MIL-STD or aerospace hardware standards, such as DO-254 exposure.
• Embedded systems or FPGA-adjacent hardware experience.
• Experience supporting hardware in integration, test, or flight environments.

Responsibilities

• Own avionics hardware from architecture and schematic design through PCB layout, bring-up, and production support.
• Drive design decisions, including component selection, interfaces, and system tradeoffs.
• Lead hardware bring-up, debugging, and root-cause analysis across lab, integration, and flight test.
• Collaborate cross-functionally to ensure avionics hardware meets performance, reliability, and mission requirements.
• Define and execute hardware validation strategies appropriate to development and flight maturity.
• Produce clear technical documentation covering designs, test results, and engineering changes.
• Partner with manufacturing and suppliers to transition hardware from prototype to production.
• Continuously improve designs based on test results, field data, and evolving requirements.
