This subsystem performs the critically important functions of signal generation, transmission, and transmitter control to send spacecraft command data as well as the tracking functions to implement spacecraft ranging. This role focuses on real-time signal processing software that interfaces with Software Defined Radios (SDRs) and FPGA-based hardware to generate modulated RF uplink signals supporting all NASA deep-space missions. You will be a member of the Control Systems and Electronics Group and work closely with teammates across the section supporting all phases of the lifecycle from inception through the end of maturity. Tasks include but are not limited to: * Design, implement, test, and ship iterations of the uplink software package. * Lead and mentor a small team of software and test engineers, providing technical guidance and managing dependencies. * Own the software side of the interface to FPGA and mixed-signal hardware, defining and negotiating that boundary with the project team. * Develop and maintain the signal processing capability of Uplink (error correction, modulation, signal generation), interfacing with software-defined radio (SDR) systems. * Architect and maintain high-rate data paths between hardware and software, accountable for data integrity and timing across the path. * Define the verification strategy for the subsystem and build the automated test capability that supports it. * Maintain the software release schedule, balancing critical mission milestones with the capability and resources of the team. * Make technical architecture decisions and defend them to stakeholders and leadership. * Present updates of the project to program leadership in review meetings (PDR, CDR, etc.) showing the project meets the expected capability and minimizes risk. * Work cross-collaboratively with stakeholders of the internal interfaces to the subsystem and the external users of the subsystem. * Perform hands-on work testing and evaluating the software deployments in the lab and in the field ensuring requirements are satisfied. * Work closely with OEs and engineers at the three DSN complexes worldwide (USA, Spain, and Australia). * Travel occasionally (<= 5% of your time) to the DSN complexes to support installation, checkout, or debugging of deployments. ## Related Videos - [Strange New Worlds: shaping the future of the digital age](https://www.wearedevelopers.com/videos/677-strange-new-worlds-shaping-the-future-of-the-digital-age) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [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) - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Bringing AI Model Testing and Prompt Management to Your Codebase with GitHub Models](https://www.wearedevelopers.com/videos/1536-bringing-ai-model-testing-and-prompt-management-to-your-codebase-with-github-models) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard)
