Job Title: AI Systems Engineer
Salary: $180k - $200k + Equity
Company Description: VC-backed AI automation startup
Job Description:
You will build production-grade AI agents designed to execute complex, multi-step workflows with absolute reliability. Moving beyond simple demos, you will architect the infrastructure for validation, failure handling, and feedback loops. Your work ensures that autonomous systems produce correct outcomes in high-stakes environments, turning ambiguous LLM outputs into dependable, structured enterprise solutions.
Location: San Francisco, USA
Why this role is remarkable:
Work at the actual frontier of software engineering by moving AI from "vibe coding" to verifiable production systems.
Join a fast-growing team backed by top-tier VCs and Y Combinator, tackling the massive bottleneck of AI reliability.
Influence the core architecture of an agentic platform where success is measured by correctness and autonomous completion of real-world work.
What you will do:
Architect autonomous agents capable of executing multi-step workflows and complex logic transitions.
Design robust systems for validation, automated retries, and sophisticated failure handling to ensure system integrity.
Build internal developer tools and feedback loops that allow the system to detect, debug, and improve from failures.
The ideal candidate:
Has 3+ years of experience in systems engineering, backend infrastructure, or building high-reliability internal platforms.
Thinks in terms of constraints, invariants, and schemas rather than just feature development or prompt engineering.
Possesses a deep interest in debugging complex, non-deterministic problems and a passion for architectural correctness over simple output quality.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
