About this role
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 in production and serving on our own cluster. What we need now is engineering. New features, better products, sharper agents and tooling. These are the layers where value is really engineered. Seattle works the layer above the models. 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.
$110,000 to $175,000 USD. Health, dental and vision covered, 401(k), paid leave. Real work, no bullshit.
Process.
1. Apply below.
2. A 20-minute intro call. We learn about you, you learn about Maincode.
3. Technical assignment + review interview.
4. Meeting the team + decisions.
Highly selective and intentional at each stage.
US work authorization required.

About this listing
Published on Ashby under the board identifier Maincode, which is the name the employer’s own job board carries. RoleSprint has not verified the company’s registered or trading name, so it is shown exactly as published rather than tidied up.
RoleSprint is not the employer and not a recruiter. Applications are made on the employer’s own site and never reach us; what RoleSprint does is help you decide whether a role is worth your time and prepare for it if it is.
