Network Infrastructure Engineer

Network engineers to build the routing, switching, and troubleshooting scenarios frontier AI labs use to test model judgment.

AfterQuery builds the expert evaluation data that frontier AI labs use to measure and improve their models. We're hiring network engineers as contractors to author and grade the routing, switching, and troubleshooting scenarios those evaluations run on.

What you'll actually do

Author realistic network scenarios, from design questions through outage troubleshooting

Write reference answers with the design and troubleshooting reasoning behind each decision

Grade model output for protocol accuracy and operational soundness

Flag configurations that read plausible but would break production networks

Who this is for

Engineers with at least 2 years of network engineering or administration experience

Practitioners with hands on routing, switching, and firewall experience in production

Engineers with depth in protocols such as BGP, OSPF, VLANs, and VPNs

Clear writers who can document the reasoning behind a design or troubleshooting decision

Contract and pay

$80 to $120/hr, paid weekly via Stripe. Your rate is set from your experience, not negotiated down after you start.

Remote, fully async. No fixed hours.

Minimum 10 hours per week, no maximum. Scale up or down week to week.

Independent contractor. Ongoing project work rather than single task batches.

About AfterQuery

AfterQuery is an expert data lab. We build the evaluation and training data that frontier AI labs use to measure what their models can and can't do in real professional work. Our contributors are practicing professionals, not annotators, and the work is credited, reviewed, and paid at professional rates.

AfterQuery is a research lab investigating the boundaries of artificial intelligence through novel datasets and experimentation. We believe great AI comes from exceptional, human-generated data.

We're backed by top investors, including Y Combinator and Box Group, and support all leading AI labs.
