Software Engineer, Infrastructure & Performance

About the role

Dedalus Labs builds persistent computers for AI agents. Our flagship product, Dedalus Machines, gives agents an isolated environment where they can run software, keep files and state, and work over time.

We're looking for an infrastructure engineer who's bothered by a slow build, an unexplained latency spike, or a workflow that makes engineers do the same work twice. You want to understand where the time went. Then you want to fix it, measure the improvement, and make sure everyone who uses that system benefits from it.

At a small startup, those details affect how quickly the whole company can move. A build that wastes ten minutes wastes them repeatedly. A confusing API slows every product built on it. A deployment that needs someone to supervise it interrupts work elsewhere. You'll seek out these problems across our systems and codebase, including the ones people have learned to tolerate. Your work can bring product releases and customer commitments forward by weeks, and over time, months.

You'll work directly with our CTO and engineers, with substantial freedom to investigate, experiment, and choose an approach. We want someone who takes pride in the craft of software engineering and cares about the systems they'll leave for the next person. That means useful abstractions, clear failure behavior, tests that establish the right guara
