Systems Software Engineer

Who we are Neros is a defense technology company rebuilding America’s drone industrial base. We design and manufacture high-performance unmanned systems that are tested in combat, iterated at startup speed, and built at massive scale. Our team culture is fast, hands-on, and obsessed with closing the gap between design and deployment. As drones transform the character of warfare, Neros is delivering the systems the West needs to compete on the modern battlefield and deter the adversaries of democracy. We’re hiring engineers, operators, and builders who want to move fast, take on extreme ownership, and get capability into the hands of warfighters in months, not years. What you will be doing Are you a hands-on Test Systems Software Engineer eager to architect the digital backbone of our hardware validation? Neros is seeking a talented individual to design and own the software frameworks that exercise our drones from the first prototype to full-scale deployment. This high-impact role reports directly to our Head of NPI & Test and offers an opportunity to build modular, scalable test libraries for cutting-edge defense tech. Responsibilities Software Architecture: Design and implement modular, object-oriented test automation frameworks in Python to control complex drone subsystems Driver Development: Write and maintain low-level drivers and wrappers for lab instruments (Spectrum Analyzers, DC Power Supplies, Oscilloscopes) using SCPI, VISA, or native APIs Telemetry & Protocols: Develop software to sniff, parse, and analyze high-speed telemetry data to validate system-level performance GUI Development: Create intuitive, high-performance Graphical User Interfaces (GUIs) using frameworks for use by technicians and R&D engineers Hardware-in-the-Loop (HIL): Support the development of HIL environments, simulating sensor inputs (IMU, GPS) to validate flight control software Robustness: Implement unit testing and continuous integration (CI) for test software to ensure that "test code" is as reliable as "flight code" You should have the following B.S. in Computer Science, Computer Engineering, or Electrical Engineering with a strong software focus 5+ years of experience in software development, specifically for hardware-centric applications Expertise in Python: Deep knowledge of asynchronous programming, threading, and hardware communication libraries Hardware Fluency: Ability to read schematics and use debugging tools (Logic Analyzers, Scopes) to troubleshoot communication between your software and the hardware Protocol Mastery: Hands-on experience with hardware buses: I2C, SPI, UART, CAN, and USB Systems Thinking: Understanding of how to abstract hardware functions into reusable software classes Nice to have Signal Processing: Experience writing scripts for automated RF characterization or vibration spectral analysis Embedded Exposure: Ability to write or modify C/C++ firmware to add "test hooks" for the high-level automation suite US Salary Range $100,000 - $170,000 USD The salary range for this role is an estimate based on a wide range of compensation factors, inclusive of base salary only. Actual salary may vary based on (but not limited to) work experience, education and/or training, critical skills, and/or business considerations.
