Neon Aero is seeking a Senior Embedded Systems Software Engineer with strong systems intuition and a passion for building robust, safety-critical control software to work onsite in Irvine, Ca. This role sits at the intersection of embedded platform software, and system-level control logic owning the supervisory control layers that coordinate actuators, motor drives, and flight-level systems.

You will architect and implement system control logic, state machines, sequencing, diagnostics, and communication interfaces that ensure safe, deterministic operation across complex aerospace systems. While this role interfaces closely with actuator control, BMS, and vehicle control software, its primary focus is system behavior, integration, and correctness…not fast inner-loop control.

This role defines how complex control systems behave as a whole. Your work ensures that motors, actuators, power, and climate systems operate coherently, safely, and predictably under all conditions. You’ll have deep technical ownership and influence system architecture decisions. Play a key role in bringing flight-ready control systems from concept to deployment.

Why This Role Matters

System Control Architecture & Logic

• Design and own system-level control architecture spanning actuator control, power sequencing, and operational state management.
• Develop supervisory logic, state machines, and mode management that coordinate lower-level motor control, embedded platform software, and hardware subsystems.
• Define and implement safe power-up, power-down, input processing, fault response, and degraded operating modes consistent with system safety assessments and aerospace certification requirements.

Embedded Software Development

• Develop and maintain embedded software in C/C++ or MATLAB/Simulink on real-time microcontroller platforms (e.g., TI C2000, NXP, or comparable safety-oriented MCUs).
• Architect scalable and maintainable software frameworks supporting control execution, communication, diagnostics, and monitoring.
• Work across BSPs, middleware, and application layers to ensure deterministic behavior and system robustness.

System Interfaces & Communication

• Define, implement, and document system interfaces between controllers, subsystems, and external equipment.
• Author and maintain Interface Control Documents (ICDs) for communication protocols such as CAN (including safety-oriented profiles), ARINC 825, and other aerospace or automotive buses.
• Ensure reliable data exchange, arbitration, and fault handling across system boundaries.

Model-Based Design & Validation

• Use MATLAB/Simulink to develop and validate system-level control logic, sequencing, and coordination strategies.
• Support model-based design workflows spanning MIL, SIL, and HIL environments.
• Leverage simulation and lab data to validate system behavior across nominal, corner-case, and fault scenarios.

Integration, Test & Bring-Up

• Lead system-level integration activities across motor control, BMS, sensors, and vehicle control software.
• Support hardware bring-up, HIL testing, and lab validation, diagnosing issues that span software, hardware, and system interactions.
• Develop test strategies, automation hooks, and data analysis workflows to ensure repeatable verification.

Safety, Process & Lifecycle Support

• Support development of safety-critical embedded software by following disciplined software development processes.
• Contribute to requirements definition, traceability, verification planning, and certification readiness activities aligned with standards such as DO-178C, ARP4754/4761, or equivalent safety frameworks.
• Maintain configuration control and long-term maintainability of system software artifacts.

Required Qualifications

• 5+ years of experience developing embedded control software for complex real-time systems
• Strong proficiency in embedded C/C++ and real-time software architecture
• Experience designing system-level control logic, state machines, and sequencing
• Hands-on experience with communication protocols such as CAN (and derivatives), SPI, Ethernet, or ARINC (825/664)
• Experience with model-based design tools (MATLAB/Simulink) and SIL/HIL testing
• Proven ability to integrate and debug software across hardware, firmware, and system boundaries
• Strong analytical skills and system-level problem-solving ability

Preferred / Bonus Experience

• Experience with TI C2000, NXP, or similar real-time control microcontrollers
• Prior work on safety-critical or regulated systems (aerospace, automotive, industrial)
• Exposure to certification-oriented development processes (DO-178C, ARP4754/4761, ISO 26262 concepts)
• Experience defining software architectures and development processes for growing teams
• Background spanning motor control, BMS, or vehicle control systems
• Experience supporting production launch, field issues, and system-level validation
