Staff Software Engineer, AI

Salary: $200K – $240K + Equity

Company Description: Well-funded AI infrastructure startup

Job Description:
You will lead the development of autonomous AI agents designed to automate complex SRE and production operations. This role involves building robust reasoning engines, evaluation frameworks, and self-improving systems. You will bridge the gap between high-scale infrastructure and machine learning to solve non-deterministic engineering challenges at scale for global technology companies.

Location: San Francisco, USA

Why this role is remarkable:

• Work at the cutting edge of autonomous agents, moving beyond simple chatbots to systems that remediate production issues independently

• Join an elite team of AI and infrastructure veterans backed by top-tier venture capital firms and prominent Silicon Valley angels

• Influence the foundational architecture of a product already deployed at high-scale technology companies in fintech and autonomous vehicle sectors

What you will do:

• Design and implement sophisticated agent evaluation frameworks to measure and improve reasoning performance and system reliability

• Build autonomous agents capable of executing complex, multi-step tasks across distributed infrastructure environments including Kubernetes and Kafka

• Debug agent behavior by tracing reasoning paths and tool-calling logic to resolve non-deterministic failures in production

The ideal candidate:

• Deep experience building and operating high-scale production systems with a strong foundation in ML fundamentals and evaluation metrics

• Proven track record of building at least one autonomous agent end-to-end and a preference for using AI-augmented workflows

• Expert-level proficiency in Python and experience with systems languages like Rust, Go, or JVM-based languages for scalable backend development

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.
