Overview
Mercor places engineers inside a leading AI lab's GenAI group, and this seat sits on the data side of that work. You bring deep systems knowledge in embedded systems, Linux kernel or RTL design and turn it into training material that shapes how large language models reason about low-level problems. Day to day you write and review hard technical tasks covering memory management, concurrency, device drivers, RTOS behavior and hardware verification, then explain your judgment in writing. The role runs part-time, at least 20 hours across weekdays, as W-2 employment with Cincinnatus LLC while you work inside the client's extended workforce.
What You'll Do7
- Spot gaps in how models handle embedded and kernel topics, then point research and engineering teams toward fixes.
- Write domain tasks on memory management, concurrency, device drivers, RTOS behavior and hardware description languages, and pair each one with a correct, well-structured solution.
- Review submitted tasks and solutions, then give clear written technical feedback the submitter can act on.
- Build grading rubrics that judge correctness, safety and performance of systems-level and hardware design answers.
- Check hardware design and verification work, including RTL, for accuracy.
- Compare notes with other subject matter experts so training data stays consistent and correct.
- Explain tricky technical tradeoffs in plain written prose for an audience of researchers.
Requirements6
- 4+ years of dedicated professional work in embedded systems, firmware, OS kernel or chip design at a top-tier semiconductor, OS, device, automotive or aerospace organization.
- Production-level C and/or C++ for resource-constrained or performance-critical code.
- Hands-on depth in at least one of: Linux kernel or driver work, RTOS and firmware, or RTL design and verification with Verilog, SystemVerilog, VHDL or UVM.
- A career track that shows steady progression.
- Availability of 20+ hours on weekdays.
- Strong written communication and the ability to lay out complex technical decisions in clear prose.
Who Should Apply
Senior embedded, kernel, firmware or RTL engineers who have shipped production C or C++ at a top-tier org and want their systems knowledge to shape AI training data. Expect part-time hours, written technical review, and close work with researchers.
Salary Insight
The range is $100 to $150 per hour, paid W-2 through Cincinnatus. For part-time systems work of roughly 20 hours a week, that band sits well above typical embedded contract rates and matches senior specialists with kernel, firmware or RTL depth.
