What is an on call operating system developer?

On Call Operating System Developers are specialized software engineers responsible for maintaining, troubleshooting, and improving operating systems, often in real-time or emergency scenarios. They are typically available outside of regular business hours to address critical bugs, security vulnerabilities, or system outages. Their work ensures that operating systems remain stable, secure, and performant, especially when unexpected issues arise. These developers need deep technical expertise in OS internals and must be able to quickly diagnose and resolve complex problems.

What are the key skills and qualifications needed to thrive as an on call operating system developer?

To thrive as an On Call Operating System Developer, you need deep expertise in low-level programming, operating system architecture, and debugging, often backed by a degree in computer science or related fields. Proficiency with languages like C/C++, debugging tools (e.g., GDB, WinDbg), and familiarity with version control systems such as Git are typically required. Strong problem-solving abilities, quick decision-making, and effective communication are vital soft skills for responding to urgent production incidents. These capabilities are crucial to rapidly diagnose, address, and prevent system-level failures, ensuring system stability and uptime.

How does the on-call aspect of an operating system developer role impact work-life balance and daily routines?

As an On Call Operating System Developer, you may be required to respond to critical system issues or outages outside of regular business hours. This can mean unpredictable work schedules during on-call periods, but teams often rotate responsibilities to help maintain work-life balance. It's important to have strong time management skills and clear communication with your team to ensure coverage and minimize disruptions. Many organizations provide compensatory time off or additional pay for on-call duties, and being on call offers valuable experience in troubleshooting high-stakes, real-world problems.

Edge Operating System Engineer

Singularity Defense Corp.

Gardena, CA • On-site

Full-time

Re-posted 3 days ago

Job description

About the Company:
We are a stealth-mode Aerospace & Defense startup headquartered in Gardena, CA. Our founding team hails from SpaceX, Anduril, and Lockheed Martin, and we are backed by Joint Staff-level military leadership and several Silicon Valley firms. With a world-class business development & leadership team already in place, we are well positioned to capitalize on already overwhelming demand.
Job Overview:
We're looking for a Senior Software Engineer focused on Edge Operating Systems to own the low-level software stack powering our NVIDIA Orin NX-based flight computer. In this role, you'll be responsible for architecting and maintaining our custom NixOS-based deployment and configuration pipeline, building high-reliability Linux systems optimized for flight, and integrating performance-critical applications into a secure, deterministic edge compute environment.
If you thrive at the intersection of embedded systems, Linux internals, and reproducible builds-and want your work to directly shape national defense-this is your role.
Key Responsibilities:
  • Own image lifecycle for our flight computers, from hardware bring-up to mission deployment
  • Build secure, minimal, reproducible NixOS configurations for NVIDIA Jetson Orin NX
  • Optimize performance, boot time, and reliability for mission-critical deployments
  • Integrate low-level software components (GStreamer, CUDA, GPU drivers, telemetry, real-time threads) into a cohesive system
  • Work closely with flight software and GNC teams to support real-time, multi-process workloads
  • Develop secure update mechanisms, sandboxing, and observability tools for edge devices in hostile environments
  • Lead debugging and performance analysis efforts across user space, kernel space, and hardware interfaces
  • Contribute to devops and CI pipelines for embedded Linux builds and simulation environments

Basic Qualifications:
  • Bachelor's degree in Computer Science, Electrical Engineering, or related technical field
  • 5+ years of experience building or maintaining embedded Linux systems (Yocto, Buildroot, NixOS, or similar)
  • Deep familiarity with Linux internals: systemd, udev, bootloaders (e.g., U-Boot), networking, filesystems
  • Fluency in shell scripting and programming in Python, Rust, or C
  • Hands-on experience with NVIDIA Jetson platforms, including GPU and camera stack integration
  • Experience debugging kernel-space and user-space issues on embedded targets

Preferred Qualifications:
  • Advanced degree or research experience in operating systems, embedded systems, or security
  • Experience using Nix/NixOS in production for embedded or robotics systems
  • Familiarity with secure boot, TPMs, cryptographic key management, and OTA update systems
  • Knowledge of CUDA, GStreamer, or other high-performance Linux subsystems
  • Prior work on autonomous systems, aerospace, or other safety-critical domains
  • Contributions to open source operating systems or Nix community projects

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) Asylum under 8 U.S.C.1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
