About Us

Viaduct builds production-grade AI systems for the world's manufacturers: not pilots, not proofs of concept. The Internal Efficiencies team is deploying real AI use cases inside one of Japan's largest manufacturers - a modern cloud and AI stack, shipped all the way down to a plant floor running robots, lasers, and IoT gear most software teams never get near.

We're a new team building fast. Viaduct already has a sophisticated, battle-tested platform - AWS landing zone, Terraform, AKS, Postgres, ClickHouse, Argo, observability - with genuinely great bones. But that platform was built to host production SaaS applications, and our team's needs don't look like that. We need our own environment, built on the lessons of what already exists, but shaped around how we actually work: fast iteration, new tooling, production use cases shipping constantly.

Who You Are

You're an experienced software developer who's shipped end-to-end, from ideation to production, and doesn't flinch at getting into the weeds of a customer's environment when it counts. You care deeply about engineering best practices and know how to collaborate closely with a senior architect and own significant implementation decisions yourself, rather than waiting to be handed a spec. You like mentoring engineers as much as writing code. You write code to create impact in the real world, not just creating endless prototypes or building other people's ideas.
