This role will join our team of qualified, diverse individuals in the Space Systems organization developing space vehicle hardware-in-the-loop simulation platforms for large and small space programs. These high-fidelity test platforms provide a hardware/software facsimile of space vehicle component interfaces to flight processors for flight software and mission development and qualification. The candidate will be part of a small design team supporting various programs such as National Security Space systems, NASA space science missions, and communication satellites. This position will sit in Dulles, VA and requires the ability to obtain and maintain a TS/SCI clearance. This position will work a 9/80 schedule, with every other Friday off. This position is 100% onsite and cannot accommodate telecommute work., * Establish simulation requirements for hardware in the loop platforms. * Select off-the-shelf or design interface hardware to simulate space vehicle components (actuators, sensors, and payloads). * Develop simulation software models and software interfaces to simulation hardware cards, including digital, analog, serial, and SpaceWire. * Define simulation testbed harnessing based on the space vehicle flight harness and simulation requirements. * Interface with hardware engineers in the design, build, and test of the simulation platforms. * Implement software control of simulation platform test equipment. * Develop and execute simulation certification loop back testing. * Work with program engineers to integrate components and flight software with the simulation platform. * Use common lab equipment (oscilloscopes, break out boxes, multimeters, interface analyzers) for debug and problem resolution. * Prepare design documentation, analysis, test results and presentation materials for internal and external customers. * Work in an innovative environment across diverse assignments and in collaborative team settings across all levels. * Other duties as assigned If this job description reads like it was written specifically for you, consider joining our team! This position is contingent upon the candidate obtaining final clearances and program access(es) within a reasonable period of time as determined by the company. This position can be filled at either a Level 3 or Level 4. ## Related Videos - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Improving quality with Agentic AI with Rovo Dev and Xray](https://www.wearedevelopers.com/videos/2005-improving-quality-with-agentic-ai-with-rovo-dev-and-xray) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Git for Code Reviews](https://www.wearedevelopers.com/videos/429-git-for-code-reviews) - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) ## Related Articles - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers) - [What Jobs Can You Get with a Software Engineering Degree?](https://www.wearedevelopers.com/magazine/398-what-jobs-can-you-get-with-a-software-engineering-degree)
