Candidate guide
The questions candidates ask before moving into AI infrastructure.
Straight answers to what engineers ask us most: what the work is, what it pays, whether remote is real, and how to get considered for roles that are never posted.

The short answer
The short version: AI infrastructure roles pay at or above general software infrastructure, remote exists but is rarer than in pure software, you do not need a machine learning background, and a large share of the best seats are filled through search firms before they are ever posted. The rest of this page is the longer answer to each of those.
Do I need a machine learning background?
No. AI infrastructure engineers build and run the platform that models train and serve on: clusters, networking, storage, orchestration and inference serving. The work is infrastructure engineering against a demanding workload, not model development.
The backgrounds that convert best are site reliability engineering, platform engineering, high-performance computing, cloud infrastructure, and data center platform roles. What employers screen for is evidence you have operated demanding systems at scale, not model knowledge.
What do these roles pay?
Pay varies by employer type and market, and the bands move faster than annual surveys. Hyperscalers and AI labs set the ceiling, GPU cloud providers compete on equity and scope, and owner-side data center teams compete on stability and the novelty of the work.
For directional numbers, search the role bands in our salary table and market calculator and adjust for the market you are in. Treat the output as calibration for a conversation, not as an offer.
Is remote work realistic?
Sometimes, and less often than in pure software. Platform and orchestration seats are frequently remote or hybrid. Anything that touches the physical fleet, including cluster operations, commissioning-adjacent work and capacity planning, tends to be on site or near a metro with build volume.
If remote is a hard requirement, say so in the first conversation. It changes which employers are realistic, and it is much easier to screen for at the start than after three interviews.
Do certifications matter?
Less than evidence. A Kubernetes or networking certification is a fine signal at the junior end, but senior screens revolve around what you have operated: cluster size, failure scenarios you have owned, and what you changed as a result.
If you are converting from an adjacent field, the strongest move is building evidence first: a home cluster, contributions to orchestration tooling, or a reliability project you can walk through in detail.
How do these roles actually get filled?
A large share of the best seats are filled through search firms and direct approach before they are posted publicly, because the qualified pool is small and employers know postings underperform for it. That is why the engineers who hear about these roles first are the ones already in a recruiter's network.
Joining the talent network is the practical version of that: you hear about roles matched to your background, including confidential searches that never appear on a job board, and you decide per conversation whether to pursue anything.

Questions
What employers ask about this.
- Do I need machine learning experience for AI infrastructure roles?
- No. The role is infrastructure engineering: clusters, networking, storage and orchestration. SRE, platform, HPC and cloud infrastructure backgrounds convert best.
- Can I do AI infrastructure work remotely?
- Platform and orchestration seats are often remote or hybrid. Roles touching the physical fleet, like cluster operations and capacity planning, are usually on site or near a major build market.
- What should I put on my resume to convert from an adjacent field?
- Evidence of operating demanding systems at scale: fleet sizes, failure scenarios you owned, and what you changed. Certifications help at the junior end but do not substitute for that evidence.
- Why do recruiters contact me about roles that are not posted?
- Because many of the best seats are filled through direct approach before posting. The qualified pool is small, and employers know postings underperform for it.
- What does it cost me to work with Critical Path Hiring?
- Nothing. Candidates never pay. The employer pays the search fee, and our job is to match you with a seat you will actually want to stay in.
