Full-Stack Engineer
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 SECONDCandidates 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 AGENCYWhat 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 → ITERATEThey shouldn't need:CUSTOMER → PM → PRD → ENGINEERThey should be comfortable collapsing that chain themselves.RequirementsMust Haves:3-7 years full-stack engineeringStrong production engineeringOwns systems data layer → backend → UIHands-on LLM/agent experience or compelling evidence of ability to ramp rapidlyStrong technical problem solvingComfortable with ambiguityExcellent communicationDirect customer interactionProduct instinctsHigh agencyCan define what to build rather than waiting for specsSF / willing to relocate5 days/week in officeAbout 30% of the role is customer-facing, which is unusually important for this search.Strong Green Flags:PalantirDatabricksDatadogCognitionDecagonSierraLinearCursorRampFigmaVercelCockroachDBRetoolModalAnyscaleRunwayApplied IntuitionAndurilNotionNomicMotherDuckStrong product company + technical depthFDE / Solutions Engineer with serious coding depthEarly startup engineerEx-founderFounder-to-be profileCoding competitionsResearch + production engineeringAI evalsObservabilityAgent behavior monitoringNice-to-Haves:Agent evalsObservabilityAgent behavior monitoringFDE experienceSolutions engineeringFounder backgroundEarly startupStrong infrastructureBackend depthAI product experienceCoding competitionsResearch experienceRed Flags:Agent experience but mediocre engineeringAI wrapper/demo experienceResearch without production ownershipPure backend/infrastructure without product rangePure frontend without systems depthNever owned data → UINo customer-facing experienceNeeds specifications handed downWeak communicatorTreats FDE/product engineering as a fallbackSlow-moving candidate / weak commitmentCannot work in SFBenefitsCompensation: $200K-$300K + equity
