Senior Real-Time/Controls Software Engineer

A New Paradigm For Space Operations. Who We Are:   Space Kinetic is a dual use space technology startup building a completely new architecture for space operations – one that brings the advantages of proliferated drone technology (low-cost, operationally flexible, attritable, distributed) to space missions while reducing the ecosystem's reliance on consumable fuel. In a world where many companies are focused on incrementally improving the status quo,  we are focused on creating something entirely different – an architecture underpinned by new first principles to meet the opportunities and challenges of the third space age head-on.  Our goal is to move away from one-to-one space architectures – where each satellite in a constellation has one (or a small # of) primary payloads attached to the bus -- and unlock a ‘one-to-many’ system, where each satellite has a large number of payloads which can be deployed from their host spacecraft at high velocities without firing a thruster. This is not a role for someone looking for a traditional 40-hour work week. Space Kinetic is building ambitious, first-of-its-kind technology, and that requires urgency, ownership, and a high level of commitment to changing the foundational assumptions for everything we do in space 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    Experince working with space systems What We’d Love: PhD in Aerospace Engineering, Mechanical Engineering, Robotics, Computer Science, or a related field. Compensation will be commensurate with experience, education, and demonstrated technical depth. 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. Where You’ll Be:   The position is onsite at our headquarters in El Segundo, CA. Domestic travel may be required (up to ~20% of the year).   What We Offer:    Equity-Based Compensation Highly Competitive PTO and Holiday Calendar Comprehensive Medical, Dental, and Vision Coverage Unique Performance-Based Bonus Structure Health and Wellness Stipend Commuter Benefits ITAR Requirements:    To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State. Learn more about ITAR  here   Equal Employment Opportunity:   Space Kinetic provides equal employment opportunities to all employees and applicants without regard to race, color, religion, age, sex, gender identity, sexual orientation, national origin, veteran status, disability or any other legally protected statu
