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
About 30% of the role is customer-facing, which is unusually important for this search.
