Specialist search · retrieval · RAG · ranking · agentic systems

Hire the engineer who can actually build your retrieval stack.
Pay only when they start.

HatAlign · Relevance is a specialist, done-for-you search practice for AI-native startups hiring in retrieval, RAG, semantic search, embeddings, ranking, recommendation, and agentic search. The roles where every resume lists the same words and only a handful of people can truly do the work. Every candidate is found and screened with AI, then personally assessed and vetted by a former Amazon and Qualtrics applied-science leader, and delivered as a reasoned shortlist. No retainer. A success fee only when you hire someone you love.

No retainer · no seats · pay on hire.

Why this is hard

“ML engineer” hides five different people.

Everyone lists RAG, embeddings, and vector search now; on paper they look identical. A generalist recruiter keyword-matches and can't tell a shipped retrieval system from a weekend notebook. Sourcing tools hand you a longer list, not a better one. And on the model that is your product, a mis-hire costs a quarter of your runway.

Titles mislead

“Applied scientist,” “ML engineer,” “search engineer” mean three different jobs. The right person is defined by what they've owned, not the label.

Resumes are inflated

Every profile pattern-matches the buzzwords. The signal is in the evidence: papers, code, systems shipped, that most recruiters can't read.

The best never apply

The engineer you want is heads-down and passive. They ignore agencies and generic InMail. Reaching them takes a credible, specific reason.

What you actually carry

You keep the pitch and the final call. I carry the rest.

A recruiting subscription still leaves the sourcing, screening, outreach, and chasing on your plate. This doesn't. Here is the split, end to end.

How it works

AI for reach and speed. A domain expert for the judgment.

01

Scope the role

A 30-minute intake to decompose what you actually need behind the title. We align on 2-3 example profiles before any full search.

02

Find & screen

AI-native search and deep screening across the web, papers, and code, supplemented by my high-level expert assessment before anything reaches you.

03

Vet

A real conversation with each finalist plus a light technical check, informed by staying current as an active reviewer in the field I recruit for.

04

Decision-ready shortlist

A small, ranked list where every candidate arrives as a reasoned case: why they fit, where the risks are, and what to verify.

05

You decide

Interview the right few with warm intros. Pay a success fee only when you hire someone who starts, backed by a guarantee.

Why HatAlign · Relevance

Not a cheaper agency. A different kind of partner.

Generalist recruiter

SpecializationEverythingWhatever you searchOnly retrieval / RAG / ranking / agentic

Already have a recruiter? An in-house or contract recruiter is still a generalist who can't evaluate a retrieval or ranking engineer, and a full recruiter (~$95-165K/yr, loaded) only pays off once you're making four or five hires a year. For one or two critical ML hires, a specialist on a success fee is both cheaper and deeper.

The honest exception: the one thing a specialist agency still offers is a human closer for the very hardest senior hire. For most roles you won't need it. The strongest passive candidates respond to a founder and a technical peer, not an intermediary. Because I'm an applied-science leader myself, I can step in as that peer to help close when a search is the exception. I'll tell you honestly when it is.

Why trust the judgment

I've built these systems, and hired the people who build them.

HatAlign · Relevance is led by Prashant Shiralkar. I evaluate candidates as a technical peer, not a keyword, because I've done the work, run the teams, and stay current in the field.

Builder — HatAlign
Founder, CEO, and technical architect of HatAlign, where I've built multiple agentic AI systems for hiring: Alignment Resilience and Alignment Warmth. I build the same class of retrieval and agentic systems I recruit for.
Applied science
Ex-Amazon Applied Scientist → Tech Lead Manager (web-scale knowledge extraction and knowledge graphs for Alexa; ~60%→90% accuracy). Ex-Qualtrics Applied Science Manager (RAG pipelines; embedding & reranking benchmarking for ~30% semantic-search gains).
Research & peer review
PhD in computer science (knowledge-graph mining). Google Scholar. Active reviewer for top AI and data venues (ACL, EMNLP, COLM, KDD, VLDB, WWW, to name a few). I read this work as it's published, so I know what current strong looks like.
Hiring manager
Recruited, interviewed, reviewed, and promoted applied scientists at Amazon and Qualtrics, and built teams from scratch. I've made these calls with my own runway on the line.

The offer

No retainer. No upfront fee. Pay only when you hire.

One specialist role, worked end to end: found, vetted, and delivered as a reasoned shortlist. You pay a 15% success fee on first-year salary, versus 20-30% at a specialist technical agency, only when you hire someone you love, backed by a replacement guarantee. The risk is mine, not yours.

Questions

Straight answers

How is this different from a sourcing tool?

Tools rank profiles by keyword and hand you a longer list. Here, AI does the reach and first-pass screening, then I add my own high-level expert assessment and a real conversation with each finalist before the shortlist ever reaches you. You get a decision, not a haystack.

What does the vetting involve?

I speak with each finalist and run a light technical check on the specifics of the role. Because I actively review submissions for venues like ACL, COLM, EMNLP, and VLDB, and build these systems myself, I stay current on what genuinely strong work looks like right now.

What does it cost?

A 15% success fee on the hire's first-year base salary, payable only when they're hired and start, versus 20-30% at a specialist technical agency for the same kind of search. No retainer, no upfront cost. I publish the number because the incumbents hide theirs.

What's the guarantee?

If a placed candidate doesn't work out within an agreed window, the search is redone at no additional fee. Terms are set per role in the engagement agreement.

Who makes the pitch to candidates?

You do, with ammunition. I find, assess, vet, and warm the introduction with a specific, credible reason to talk. You sell the vision. Founders close the best passive candidates, not intermediaries.

Do you recruit for other roles?

Adjacent AI/ML roles, sometimes, by referral. But retrieval, RAG, ranking, recommendation, and agentic systems are the deliberate focus. That's where the depth and the network are.
