How this pay compares
This posting states $170k–$240k a year. Open software engineer jobs in California post a median of $179k a year, the middle half $143k–$212k, across 460 jobs that state their pay, so this one is within the middle half of what they post.
About the job
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.
Job 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
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
- 401(k) retirement plan with a 3.5% company match
- Highly Competitive PTO
- Paid company holidays + winter break
- Comprehensive medical, dental, and vision insurance
- Unique Performance-based bonus opportunities
