What they're building

Expert-led dataset specification and delivery work (Operations, 9 of 11 Operations roles) strong signal

Today: "Offers ready-to-deploy datasets across high-demand capability areas" (site)

Roles: Strategic Projects Lead - STEM · Strategic Projects Lead - Healthcare · Strategic Projects Lead - Coding · Strategic Projects Lead - Consulting · Strategic Projects Lead - Engineering · Strategic Projects Lead - AI Safety · Strategic Projects Lead - Legal · Strategic Projects Lead · Strategic Projects Associate - Coding

Requirements mention: Design dataset specifications · Manage expert teams across domains · Drive high-impact execution end-to-end · dataset specifications · harm taxonomies · grading standards and evaluation criteria

Inference: the Operations group is staffing project leads who write dataset specifications and manage expert teams by domain, which suggests more domain-specific datasets are being scoped at once.

Public benchmarks and frontier evaluations (Research) moderate signal

Today: "We take a proactive stance — every domain has its own failure patterns." (site)

Roles: Research Scientist – Frontier Evaluations · Research Program Manager · Research Scholar · Research Fellow

Requirements mention: public benchmark releases · leaderboards · reproducible evaluation systems · Public benchmarks in coding and specialized domains · safety evaluations

Inference: the Research roles point toward publicly released benchmarks and leaderboards, not only internal evaluation.

Post-training and RL environment work (Research and Engineering) strong signal

Today: "Custom environments across APIs, tools, and services" (site)

Roles: Research Engineer · Software Engineer - RL Environments · Research Scientist - Post Training · Research Technical Program Manager

Requirements mention: post-training infrastructure · RL pipelines · RLVR training pipelines · SFT · RL-based post-training · reward signals

Inference: the postings describe in-house SFT and RL post-training infrastructure used to measure how AfterQuery's datasets change model behavior. This suggests the company is building its own capacity to test its data before or alongside delivery.

Data capture and pipeline platform (Engineering) moderate signal

Today: "Human-demonstrated interactions across browser and desktop environments" (site)

Roles: Software Engineer - Platform Infrastructure · Software Engineer - Platform/Applied AI · Software Engineering Intern

Requirements mention: high-throughput data pipelines · data capturing workflows · web (Next.js) · desktop (Python) · message queues

Inference: the platform and intern postings ask for web and desktop data capture with high-throughput pipelines, which suggests the capture tooling is being extended.

Expert supply and marketplace (Growth and Engineering) moderate signal

Today: "We work with domain experts to capture that thinking" (site)

Roles: Head of Growth · Growth Associate · Software Engineer - Marketplace

Requirements mention: Expert Network · Marketplace Operations · talent marketplace · segmentation, matching · growth loops · Instrument the funnel

Inference: these roles focus on recruiting and matching experts, which suggests the expert network is a priority for growth alongside dataset work.

Enterprise data acquisition with legal and privacy controls (Operations, Internal Ops, Engineering) moderate signal

Today: "We turn real-world work into training data." (site)

Roles: Data Acquisition Lead · Corporate Counsel · Machine Learning Engineer, Data Privacy & Anonymization

Requirements mention: enterprise data acquisition · data rights · data licensing agreements · data processing agreements (DPAs) · redaction · pseudonymization · re-identification attacks

Inference: alongside expert-created data, AfterQuery is hiring to license real-world data from enterprises, with contract and anonymization work built around it.
