Radiation Test Engineer

Houston, TX

About Intuitive Machines:

Intuitive Machines is an innovative and cutting-edge space company making cislunar space accessible to both public and private customers. Our mission is to further science and exploration, communications, and economic progress from the Earth to the Moon and beyond. With multiple NASA lunar missions in development and additional private missions on our manifest, we pride ourselves in supporting NASA, our customers, and the nation in paving the way to return humans to the surface of the Moon. Our world-class team includes experts in all aspects of spacecraft subsystems design, development, and test, on-orbit operations, and safety.

About the Position:

We are seeking a radiation test engineer for the Intuitive Machines NOVA-C / NOVA-D Lunar Lander and Altus Lunar Satellite programs. The role will serve as the technical authority for defining mission-based radiation environments, providing hardware design implementations to handle those environments, establishing test programs to evaluate the hardware solutions, coordinating with test facilities to execute these test programs, and analyzing the test results to quantify the hardware solutions’ ability to meet the mission objectives in the environments.

Your work will have a direct impact on program success, supporting spacecraft builds, payload integration, mission rehearsals, and full end-to-end system tests. This is a hands on, high ownership role at the center of spacecraft and payload integration. Reports to Avionics Director.

Responsibilities:

Define radiation environments per mission,

Define tests based on those environments, including these support tasks”

Create functional block & harness diagrams for the tests

Design test cables

Design (Altium) test PCBs

Perform cross section / probabilistic analyses on test results.

Develop test plans and test procedures for payload and spacecraft system testing

Track risks, integration issues, and system limitations; drive mitigation strategies

Manage configuration changes as flight hardware and payloads evolve over the program lifecycle

Ensure safe operations, access control, and hardware handling discipline

Define program requirements based on radiation environment.

Help standing up Radiation hardness program for IM. We are starting to come up on 5years of our initial testing and we are still banking on parts being the same. There are industry techniques to help mitigate this w/o having to retest every single part.

Be familiar with Radiation mitigation strategies in hardware or firmware, in an effort to mitigate / redirect usage for hardware that may have initially failed testing.

General SME consulting about radiation, parts selection, etc. Become familiar with our missions, devices, vehicle architecture, etc. to provide guidance internally to the design and development engineers.

Own test campaigns from start to finish, coordinating with engineers for designing test bench's, documenting dry runs, and test logistics. IM test conductor for all radiation tests, making real time decisions during irradiation. Follow up on test reports, implications from test data, and proper design mitigations.

Negotiates contracts for beam time for Proton and Heavey Ion test facilities.

Performs radiation analysis and supports engineering with recommended mitigation tactics.

Conducts experiments to evaluate total ionizing dose (TID), displacement damage dose (DDD), single-event effects (SEE), and dose rate effects on microelectronics and semiconductor devices.

Works with outside customers to define mission radiation requirements.

Requirements:

Bachelor’s degree in Electrical Engineering or Physics , or related field with applicable experience.

5+ years relevant experience (3+ with MS)

Handson experience with spacecraft subsystems, avionics, or hardware-in-the-loop(HWIL) testbeds

Ability to interpret electrical schematics, system diagrams, and interface definitions

Experience with test planning and test procedure development

Strong understanding of spacecraft power systems, communications, C&DH, and ground interfaces

Ability to work effectively in fast paced, evolving technical environments

U.S. citizenship

Preferred Requirements:

Scripting experience ( Labview , python, JavaScript, VBA).

Experience designing or operating Flatsat , HWIL, or spacecraft system testbed

Background in high reliability or mission critical systems

Experience supporting environmental tests or mission readiness/rehearsals
