Job description

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
