About Direct Inference

Direct Inference is the endpoint that does everything frontier models can do. Customers bring the SDK and model id they already use; Direct Inference handles capability, quality, cost, latency, failover, and provider churn behind the scenes.

The important product constraint is zero-knowledge: customers never see which model, provider, or version served a request. That lets them build on a stable surface while the model market keeps moving underneath it.

What you'll own

Design and implement polished React and Next.js interfaces across the marketing site and portal.
Improve playground, traces, analytics, billing, documentation, and onboarding workflows.
Build UI states for empty data, loading, errors, mobile screens, and high-density operational views.
Partner with product and engineering to make complex infrastructure concepts understandable.
Maintain a consistent visual system across public marketing and authenticated product surfaces.

Projects you might ship

Redesign a high-value product workflow such as traces, playground comparison, docs navigation, or spend controls.
Build a role, docs, or onboarding page that converts curiosity into a clear next step without feeling like a generic SaaS template.
Create reusable UI patterns for dense operational data: empty states, filters, mobile sheets, tables, badges, and detail panels.

What we're looking for

You have shipped production frontend experiences with strong visual and interaction quality.
You are fluent in React, TypeScript, responsive layout, accessibility, and design-system thinking.
You notice spacing, hierarchy, copy density, and edge states before someone asks.
You can work from a rough product need and shape a complete UI flow.
You value restraint: the interface should help users work, not perform at them.

Nice to have

Experience on developer tools, infrastructure dashboards, docs sites, or high-density B2B products.
Comfort writing interface copy and shaping information architecture, not only implementing mocks.
A portfolio or body of work that shows taste, craft, and care for edge states.

Your first 90 days

Ship a meaningful improvement to the careers, docs, playground, or dashboard experience.
Tighten one existing UI surface across desktop and mobile.
Codify a reusable component or pattern that makes future product work faster.
