Senior AI Systems Engineer at CloudZero · LumiJobs

Responsibilities

CloudZero is making a foundational hire in the Office of the CTO: the person who builds the data and AI platform the rest of the company operates on.
Almost everything a team needs, whether it is the pipeline number, the churn signal, or the answer an agent gives a CS rep at 4pm, depends on data that today lives across dozens of SaaS systems and is moved by hand. You'll build the layer that ends that: governed pipelines into Snowflake, a modeled surface analysts and agents can query without guessing at joins, and the environments where agents run with real identity and real cost attribution.
You'll also own the systems underneath it, including Okta, Jamf, Google Workspace, Slack, Jira, and Ravenna, because they're the identity and event substrate that the platform inherits. The Okta group that provisions a new hire's laptop is the same group that determines what an agent can access when that person invokes it. Whoever owns one should own both.
Hybrid out of our Boston office. Some flexibility outside East Coast hours helps, since our employees and customers are global.
Automation first. Manual work last.
Manual work shows up in two shapes here, and they're the same problem:
A ticket is a signal that a system failed a person. Ask why the question came up at all, and fix the upstream cause so the next ten people don't hit the same wall.
A repeated request for a number is a data product that doesn't exist yet. The third time someone pulls the same figure by hand, that's not a favor to do, it's a table you haven't modeled.
The queue and the query log are both data. Instrument them, group by root cause, and let the pattern drive your roadmap.
We're AI-Native, For Real
You reach for Claude Code, Claude Desktop, or Cursor before problem-solving manually, whether that's drafting transformations, parsing logs, reasoning about a schema you've never seen, or breaking apart messy projects.
You can talk credibly about which models and tools are good at what, where they fall short, and how to prompt them well.
