C Repository Behavior Task Author
Job Description
IXO is engaging specialists to evaluate behavioral questions that require a real understanding of a C codebase. Your contribution is technical work: make the reasoning inspectable, identify substantive errors and provide evidence that supports a reliable assessment.
Work you will do
• Investigate the repository and run the relevant code to establish what it actually does.
• Write questions whose answers depend on C implementation details and defensible runtime evidence.
• Create answer criteria and deterministic rubrics that distinguish correct explanations from plausible but unsupported guesses.
Preferred background
• At least three professional software years with substantial production C and the ability to establish runtime behavior in a large unfamiliar repository.
• Understand preprocessor/platform branches, memory ownership and build systems such as Meson, CMake or autotools; use tracing, sanitizers, debuggers and profiling to support conclusions.
• Systems, networking, databases or cryptography experience and precise written explanations are especially useful.
Deliverables
Submit the completed technical artifact or assessment with its supporting evidence, explicit assumptions, reproducible checks where applicable, and concise reasons for each material judgment. Address review findings within the agreed scope.
Location and schedule
Remote assignments are scheduled by agreement, with no guaranteed weekly volume. IXO confirms the applicable timing before work.
Pay and working terms
$140/task USD. Payment is for a completed task that meets the agreed acceptance criteria.
