Real-time job-search ranking API

Personalized themoment they search.

RoleTensor re-ranks results from in-session behavior — clicks, dwell, skips — with two-tower retrieval and a session reranker. No login. No history. Sub-200ms.

The gap

Personalization that doesn't need a profile.

Collaborative filtering needs history you don't have on a first-time visitor. Batch models can't react inside the session. Static relevance ignores what the user tells you with every click. RoleTensor learns from the session that's happening right now.

No profile

Works on anonymous, logged-out traffic.

In-session

Reacts within the same visit — not tomorrow's batch.

Signal > metadata

Behavior outranks keywords and filters.

How it works

Three steps, every search

01

Retrieve

Multi-intent two-tower search pulls thousands of candidate jobs via ANN in milliseconds.

02

Read the signals

Clicks, dwell, and skips from the current session — no profile, no cold start.

03

Re-rank live

The session reranker rescores candidates instantly, adapting as intent shifts.

Architecture

Two towers, one session-aware reranker.

A fast retrieval stage proposes; a precise, session-aware stage decides — so every result reflects what this visitor is doing right now.

Multi-intent retrieval

One search → several intent vectors, merged with RRF.

Distance-aware

Geo distance is a first-class ranking feature.

Dual-memory

Learns from clicks and skips, separately.

Cold-start ready

Query-clustering teacher covers thin history.

Language-agnostic

Every job, one vector space.

RoleTensor embeds every job and every search into one shared vector space — so matching is driven by meaning, not words. No translation, no per-language models, no keyword dictionaries.

Any language in, any language out

A query in one language finds the right jobs written in another.

No translation layer

No machine translation and no per-language models to maintain.

One model, every market

Launch a new country with zero retraining or keyword upkeep.

Why it's different

Built to personalize the un-personalizable

Real-time, in-session

Personalized from the very first search.

No login required

Runs on anonymous traffic — your majority.

Learns from skips

Negative signal shapes ranking, not just clicks.

Geo-aware

Distance is a first-class ranking feature.

Understands nuance

Salary, seniority, benefits live in the embeddings.

Adapts to intent shifts

A second search re-reads what they want.

Language-agnostic

Meaning over words — works across any language, no translation.

Outcomes

More clicks per user. More ROI. Same traffic.

Relevance gains compound where it matters — and every lift is measurable.

Integration

One API call. Under 200ms.

Send a query, the user's location, and the session's events; get back a re-ranked list of jobs — each with a tracking link. Two-tower retrieval and the session reranker run behind one endpoint, so you drop it into your existing search.
