Job Title: Founding AI Engineer — Agent Runtime

Salary: $100k-$150k + Equity

Company Description: Pareto Agent - VC-backed AI startup building a policy-driven runtime for high-stakes commercial workflows.

Job Description:
Join Pareto Agent as the first engineering hire to build the execution layer for autonomous B2B sales agents. Unlike standard LLM wrappers, you will architect a deterministic, policy-driven runtime that governs agent actions in real-world negotiations. Reporting to a serial-entrepreneur CTO, you'll ensure every AI decision protects revenue and follows strict guardrails.

Location: San Francisco, USA

Why this role is remarkable:

- Founding opportunity as the first engineer, offering significant 1.5% equity and direct influence on the technical architecture of a $3.5M-funded startup.

- Work alongside serial founders Evan Liang (ex-LeanData CEO) and Maurizio Greco (20+ year CTO) who have successfully scaled multiple B2B companies.

- Tackle deep systems engineering challenges by moving beyond simple chat interfaces to build a self-improving, safe-by-construction execution system for high-stakes commerce.

What you will do:

- Design and own the multi-stage agent pipeline, including intent classification, context assembly, and reasoning loops to enable reliable autonomous decision-making.

- Build a robust event-driven runtime and evaluation framework to enforce commercial policies and catch regressions before they impact customers.

- Architect sophisticated context management systems that determine how to retrieve, compress, and utilize data as agent complexity scales across various industries.
