Tech Hire Labs field notes
Technical writing from the Tech Hire Labs laboratory: sandbox construction, kernel and concurrency engineering, vetting methodology, and the documentation discipline behind specialized systems hiring.
STEM OPT I-983 Formal Evaluation Protocols for Core Systems Researchers
The I-983 is a training instrument, not a formality. Here is how to write objectives, supervision structure, and evaluations that survive scrutiny for low-level research roles.
read article →CPT Work Authorization Compliance for Low-Level Kernel and OS Engineers
CPT only works when the placement is genuinely integral to the curriculum. For kernel and OS internships, that link has to be written down before the first commit.

Specialty occupation arguments fail on vagueness, not on merit. Systems roles have abundant complexity evidence — most petitions simply never show it.
read article →LCA Wage Determinations for Core Rust and C++ Systems Developers
Wage level selection is a technical judgment about the role, not a budgeting exercise. Core systems roles rarely belong at Level I.

The grace period is shorter than it feels. Treat day one as the last day of employment and work backwards from the filing deadline.

A sandbox that cannot reproduce a race condition on demand is a demo. Determinism, isolation, and instrumentation are the three requirements.
read article →Memory Safety and Concurrency: Evaluating Rust for Core Enterprise Services
Rust removes an entire class of defect at compile time. The remaining engineering questions are about unsafe boundaries, async design, and team fluency.

Tail latency is an engineering budget, not a configuration flag. Measure first, then remove the largest source of variance.

Puzzle interviews measure preparation. Instrumented, workload-realistic evaluation measures the judgment the job actually requires.

Autonomy compute is a bandwidth problem wrapped in a determinism problem wrapped in a safety case. Budget all three before writing code.
