Czarina Tabayoyong
Founder and Principal Recruiter, Critical Path Hiring
Founder
Czarina Tabayoyong is the founder and principal recruiter, with more than 15 years of technical recruiting experience across software engineering, cloud infrastructure, platform, AI and ML. Her background includes recruiting cloud and data center architecture talent at AWS Professional Services, supporting high-volume recruiting across multiple job families at Amazon, recruiting for Google, and building PMO and project delivery recruiting for hyperscale data center buildouts across active campuses in Texas and Virginia.
She scopes every engagement, runs the research, makes the screening decisions and stays on through the start date. She uses AI tools to organize research and find candidates. She decides who gets submitted.
Focus
We only recruit for data center and AI infrastructure teams. The candidate pools are small, concentrated in a few metros, and mostly employed. The vocabulary takes years to learn. Working in one area lets us tell an employer early when a role can't be filled as written.
Purpose
An open commissioning, controls or platform role can delay a project or leave a live site short-staffed. Czarina builds each search around the actual work the person will do, and the employer keeps the market research for the next hire.
Clients
Hyperscale and colocation operators, GPU cloud and AI platform teams, EPC and commissioning firms, and OEMs. Searches are frequently confidential: replacing a site lead, standing up a team before a build is announced, or checking a market quietly before anyone knows you're hiring.

Hard news
If a role is not fillable as written, the compensation band is short of the market, or a staffing firm is the better answer, Czarina addresses it in the first conversation.
One recruiter
The person who calibrates the role runs the research, the outreach and the offer. There is no handoff to an account manager or a junior sourcer.
Infrastructure only
The vocabulary, pay levels and employer mix in these disciplines take years to learn.
Research ownership
Target company lists, outreach messages, pay data and pipeline notes go to your team when an engagement ends.
Commitments
We commit to research depth, outreach volume, reporting cadence and response times. Outcomes depend on market conditions, scope, compensation and process speed.
AI use
AI assists with market mapping, research organization and drafting. Czarina owns and documents every screening and submission decision.
Candidate treatment
Candidates receive the role scope, compensation range, constraints and an answer either way.
