At Orbital Paradigm, we design, develop, manufacture, and operate reusable orbital logistics systems. Our spacecraft perform multiple orbital mission profiles and return safely to Earth through hypersonic atmospheric reentry and landing with pinpoint accuracy for rapid refurbishment and reuse.

Role Description

We are looking for a Junior Avionics Engineer to join our avionics team and support the design, development, integration, and testing of avionics systems for our reusable orbital logistics vehicles.

The role covers avionics architecture, on-board computers, electronic hardware, EEE parts selection, harnessing, electrical and data interfaces, EGSE, and verification activities. The engineer will work closely with systems, GNC, software, mechanical, and AIT teams to develop reliable avionics solutions and support them from design through integration, testing, and qualification.

This role is suited for an early-career engineer with strong fundamentals, hands-on project experience, and clear motivation to work on spacecraft avionics.

Key Responsibilities




- Support avionics design, integration, and testing activities under the guidance of senior engineers.
- Assist with the development and review of electrical schematics, wiring diagrams, pinouts, and interface documentation.
- Support harness design activities, including routing, connector selection, labeling, and continuity checks.
- Assist with the selection and documentation of electronic components, connectors, sensors, actuators, and EEE parts.
- Support board-level bring-up, debugging, and validation activities for avionics hardware.
- Participate in laboratory testing, functional testing, and system-level avionics test campaigns.
- Support EGSE setup, configuration, operation, and basic troubleshooting.
- Assist with electrical and data interface verification between avionics units and spacecraft subsystems.
- Perform measurements and checks using laboratory equipment such as oscilloscopes, multimeters,
