Senior Real-Time/Controls Software Engineer

A New Paradigm For Space Operations. Who We Are: Space Kinetic is a cleared, venture-backed startup focused on addressing urgent national security priorities. Our goal is to deliver a suite of asymmetric capabilities for space superiority and missile defense leveraging our proprietary electromechanical deployment system, which enables the rapid deployment of low-cost payloads through space without firing a thruster. Space Kinetic is currently assembling its TRL-5 prototype. Our goal is to leverage this platform to provide the United States with a new tool for securing the space domain & catalyzing the emerging space economy. What You’ll Do: We are seeking a Senior Real-Time / Controls Software Engineer to lead development of deterministic real-time control software supporting high-speed electromechanical aerospace systems. This role will own motor-control implementation, release timing logic, safety interlocks, and hardware-in-the-loop (HIL) integration for critical system functions.The ideal candidate understands both controls theory and low-level real-time software implementation and can translate GNC, MATLAB/Simulink, and Python-based models into reliable embedded flight-like control software operating in a fast-paced hardware development environment. Key Responsibilities: Develop deterministic real-time control software for electromechanical aerospace systems Own motor-control implementation, release timing logic, and safety interlock architecture Translate MATLAB/Simulink and Python-based control models into production-quality real-time software Support development and integration of guidance, navigation, and control (GNC) related algorithms Design and execute hardware-in-the-loop (HIL) testing and integration activities Work closely with GNC, electrical, mechanical, and systems engineering teams during development and test Support integration, debugging, and validation of control systems on prototype hardware Develop software interfaces for sensors, actuators, motor controllers, and embedded hardware systems Support system-level testing, troubleshooting, and rapid iteration during development campaigns Participate in technical reviews, architecture discussions, and safety-critical design decisions What It Takes: Bachelor's degree in Aerospace Engineering, Electrical Engineering, Computer Engineering, Robotics, or related field OR Master’s Degree in Aerospace Engineering, Electrical Engineering, Computer Engineering or related field 5+ years of experience in embedded software, controls software, or real-time systems development Strong understanding of real-time software architecture and deterministic system behavior Experience with motor controls, actuator systems, or embedded control loops Experience working with MATLAB/Simulink and translating models into deployable software Strong programming experience in C/C++ and Python Experience supporting integration and testing of hardware/software systems What We’d Love: Aerospace, defense, robotics, or autonomous systems background Experience with HIL (Hardware-in-the-Loop) simulation and testing Familiarity with GNC algorithms and controls development workflows Experience supporting high-speed dynamic systems or safety-critical systems Familiarity with embedded Linux, RTOS, FPGA interfaces, or low-level hardware communication protocols Startup or rapid-prototyping experience preferred Real-time embedded systems Control loop implementation Motor controllers and actuator interfaces Sensor integration and signal processing Simulation and modeling workflows System debugging and integration testing Cross-functional engineering collaboration *Our vision is unique, and so is the team we’re building. If you’re driven to succeed in this role, even if your background doesn’t fully align with every qualification, we want your application.
