👻 Ghost score 7%

What it means: how likely this posting is sitting open without active hiring.How to read it: 60% or higher means we think this is a ghost. Lower scores are less of a worry.How we score it: age, reposts, open roles vs team size, how fast jobs close, and whether pay is listed.Fine print: an estimate from public data, not a judgment of the company. Real jobs can score high, so treat it as a hint, not a fact.

📋 Description

• Apply hands-on software, firmware, and digital hardware expertise to technically complex tasks involving real physical systems • Review and evaluate embedded firmware, FPGA/RTL designs, flight software, test automation frameworks, hardware interfaces, and system-level engineering workflows • Analyze architecture and implementation trade-offs involving real-time performance, timing, memory, compute resources, interfaces, reliability, fault handling, concurrency, and hardware/software integration • Assess the technical correctness, robustness, and practical feasibility of engineering solutions for embedded and hardware-connected systems • Identify implementation errors, incorrect assumptions, race conditions, timing issues, interface failures, resource constraints, and other system-level failure modes • Develop or review engineering problems, reference implementations, test cases, evaluation criteria, and technical documentation • Draw on practical experience with development, integration, hardware bring-up, debugging, verification, validation, test automation, and deployment • Provide clear technical feedback grounded in real-world engineering experience and production hardware constraints • Support an advanced engineering and AI research initiative with a leading technology organization • Help improve how AI systems reason about embedded development, hardware/software integration, digital design, real-time systems, testing, and debugging

🎯 Requirements

• 5+ years of professional software, firmware, FPGA, or embedded systems engineering experience • At least 3 years of recent, actively hands-on experience developing, integrating, testing, bringing up, or troubleshooting software/firmware on real hardware • Experience as the responsible engineer for production hardware-connected software or firmware • Experience owning lifecycle stages from requirements and architecture through implementation, integration, hardware bring-up, verification, validation, debugging, and deployment • Deep technical expertise in at least one core domain: embedded firmware and real-time systems; FPGA/RTL design and verification; flight software and safety/mission-critical systems; or hardware test automation and hardware-in-the-loop infrastructure • Practical command of C/C++, Python, RTOS/bare-metal development, device drivers, bootloaders, embedded Linux, SPI/I²C/UART/CAN/Ethernet, Verilog/SystemVerilog/VHDL, FPGA toolchains, hardware interfaces, telemetry, and automated test systems, as applicable • Hands-on experience debugging software-hardware interactions and physical systems using JTAG/SWD debuggers, logic analyzers, oscilloscopes, hardware simulators/emulators, HIL/SIL environments, automated test equipment, CI infrastructure, and structured root-cause analysis • Experience developing systems in real-world product or hardware manufacturing environments • Ability to explain architectural decisions, implementation trade-offs, test results, and failure mechanisms • Experience working for a company that designs, builds, tests, and manufactures physical hardware or embedded systems is strongly preferred • Must be an independent contractor • H1-B and STEM OPT candidates are not supported

🏖️ Benefits

• Fully remote role • Flexible engagement structures • Work on your own schedule • Weekly payments via Stripe or Wise • Projects may be extended, shortened, or concluded early depending on needs and performance • Competitive pay • Collaboration with leading researchers • Referral opportunity earning up to $480 per successful referral
