# Full-Stack Engineer

> JeffreyM Consulting · San Francisco, United States · — · Posted 2026-10-02

**Salary:** USD 200,000–300,000

**Workplace:** on_site

## Description

Description:

**Target Profile:**

Our client wants a high-caliber full-stack/product engineer who also understands LLMs and agents.

The key distinction from their Research Engineer search:

**FULL-STACK ENGINEERING FIRST → AGENT DEPTH SECOND**

Candidates do not need to be hardcore agent researchers. The client explicitly allows engineers with hands-on LLM/agent experience or demonstrable ability to ramp quickly.

**Core profile:**

**FULL-STACK → END-TO-END OWNERSHIP → AGENTS/LLMs → CUSTOMER-FACING → 0→1 → HIGH AGENCY**

**What They’ll Actually Build:**

This role owns the product that helps engineers understand **why production agents are failing and whether fixes actually work.**

**Ideal Candidate:**

Someone who can:

**TALK TO CUSTOMER → IDENTIFY PROBLEM → DESIGN PRODUCT → BUILD BACKEND → BUILD UI → SHIP → OBSERVE → ITERATE**

They shouldn't need:

**CUSTOMER → PM → PRD → ENGINEER**

They should be comfortable collapsing that chain themselves.

## Requirements

**Must Haves:**

-   3–7 years full-stack engineering
-   Strong production engineering
-   Owns systems data layer → backend → UI
-   Hands-on LLM/agent experience or compelling evidence of ability to ramp rapidly
-   Strong technical problem solving
-   Comfortable with ambiguity
-   Excellent communication
-   Direct customer interaction
-   Product instincts
-   High agency
-   Can define what to build rather than waiting for specs
-   SF / willing to relocate
-   5 days/week in office
