International Space Station Flight Controller – Flight Dynamics Officer (FDO)

Barrios Technology is an engineering solutions partner with more than 45 years of experience supporting NASA and the commercial space industry. We deliver innovative engineering, software, and technology integration services across NASA centers nationwide. Barrios prides itself on a people-focused culture that values creativity, diversity, professional growth, and a healthy work-life balance.

We need your talent, teamwork, and energy to help us achieve great things that inspire people all over the globe. Bring creative ideas and diverse backgrounds to help us envision, shape, and deliver systems that will enable the exploration of space while benefiting people here on Earth. We are excited about what we do, and we need you on our team as we take on exciting challenges for support of the International Space Station. Currently there is an exciting opportunity for an International Space Station Flight Controller – Flight Dynamics Officer (FD0) to join the Barrios team at Johnson Space Center, Houston, TX.

Since the days of Project Mercury, the Flight Dynamics Officer (FDO), pronounced “Fido”, has been one of the most enduring and critical roles in NASA’s human spaceflight operations. From the Moon landings to commercial crew launches, FDOs have helped shape the trajectory, literally and figuratively, of crewed and uncrewed spacecraft.
This position supports the Flight Dynamics Division within NASA’s Flight Operations Directorate at Johnson Space Center under the Integrated Mission Operations Contract III (IMOC III). As a contract FDO, you will train toward certification through individual study, simulations, and proficiency evaluations, ultimately supporting real-time mission operations from console. You’ll be responsible for trajectory planning, launch and reentry monitoring, and in-orbit maneuver analysis, contributing directly to the success of Artemis, HLS, and Commercial Crew missions.
FDOs train to become certified flight controllers by completing individual study, simulations, and proficiency evaluations. Once certified, FDOs support real-time mission operations, developing and validating trajectory plans, monitoring vehicle performance during launch, reentry, and in-orbit operations, calculating maneuver plans, analyzing contingency scenarios, and supporting the overall trajectory and energy management of the spacecraft.
The role requires daily collaboration with NASA teams and other contractors, cross-disciplinary communication between analysts, developers, and flight controllers, creation and review of mission documentation, and participation in simulations and mission events. Shift work is required during active mission periods and may include early mornings, evenings, weekends, holidays, and on-call availability as needed.
The position also involves software tool development, data validation, and analysis, directly supporting real-time operations. As a member of the FDO Team, you will contribute to the development and verification of mission-critical applications, tools used to assess abort scenarios, conjunction risks, and launch opportunities for Artemis missions. As part of the Software Development Life Cycle, you will participate in code reviews, unit testing, and software documentation (SRS, ATPR), ensuring compliance with NASA and Flight Dynamics Division standards for safety-critical tools.
FDOs work in a dynamic, high-pressure environment where teamwork, quick decision-making, and adaptability to evolving mission requirements and emerging technologies, including AI-driven automation and trajectory analysis integration, are essential.
Due to the sensitive and mission-critical nature of the work, employees must comply with NASA’s information security policies and properly handle privileged data.
Occasional travel may be required to support mission or technical forums. Travel is expected to be limited (up to 25%).
This position is ideal for candidates who are passionate about combining aerospace engineering and real-time mission operations. It provides the opportunity to contribute to Artemis II and beyond, supporting NASA’s return to the Moon and future deep space missions. Successful candidates will develop hands-on expertise in trajectory design, mission simulation, and safety-critical software, growing toward Flight Dynamics Officer FDO certification and long-term leadership within NASA’s flight operations community.
This position is based at NASA’s Johnson Space Center in Houston, Texas. On-site presence is required to support real-time mission operations, flight controller training, and team collaboration.
