Job description

Maincode · Seattle, WA · On-site

Engineers wanted for hard work on real problems. Small team, flat hierarchy, high agency, real work. Full ownership over what you build.

Maincode is building Matilda, Australian-made AI. Most of the team is in Melbourne, but we are building out an office in Seattle.

The work.

Matilda is up and running: app, web, CLI, and desktop - all deployed and serving on our own cluster. What we need now is engineering. New features, better products, faster inference, sharper tooling. The team is around a dozen people, so nothing here is a ticket queue. You see what matters, you build it, and it is in production that week.

You.

The bar is high. We want exceptional engineers who build because they cannot help it, who move without being told to, and who would rather be handed a problem than a spec. No process theatre, no politics, just engineering.

Benefits.

$130,000 to $175,000 USD. Health, dental and vision covered, 401(k), paid leave. Real work, no bullshit.

Process.

  1. Apply below.

  2. A 30-minute call. We learn about you, you learn about Maincode.

  3. Technical assignment.

  4. We will be in Seattle in September, and we will fly the strongest applicants to meet with us in person.

  5. Same-day decision.

Highly selective and intentional at each stage.

US work authorization required.
