Job description

Service status · A8 Core™ · The Operating System for Financial Accounts · The account operating system · API-first

Design the developer experience for an API-first platform — clear, fast, and trustworthy from first call to production.

Location Remote (United States) Reports to Head of Product Team Design

Design the developer experience for an API-first platform — clear, fast, and trustworthy from first call to production.

A8 Core™’s product is its API and the surfaces around it: the dashboard, the documentation, onboarding, and key management. Most financial infrastructure has genuinely poor developer experience. This role owns the design of A8 Core™’s — the systems and flows that make a developer’s first integration feel obvious and their hundredth feel effortless.

What you’ll own

Developer surfaces

• The dashboard, API reference experience, onboarding, and developer console.
• The end-to-end flow from sign-up to first successful API call.

Design systems

• The design system, patterns, and documentation experience that keep every surface coherent.

Key flows

• API key management, integration setup, and the monitoring views developers live in.

Research

• The study of real developer workflows, usability, and feedback that grounds every decision.

Responsibilities

• Design developer-facing surfaces end to end, from concept to shipped detail.
• Build and extend the design system that keeps the product coherent as it grows.
• Improve documentation and onboarding so time-to-first-call keeps dropping.
• Partner closely with Engineering on faithful, high-quality implementation.
• Run lightweight research with developers and turn findings into design decisions.
• Hold and raise the quality bar for everything a developer sees and touches.

Qualifications

Required

• 5+ years in product design, including work for technical or developer audiences or genuinely complex products.
• Strong systems thinking and fluency with modern design tooling and design systems.
• A portfolio of shipped work that shows craft and clarity under complexity.
• The ability to make dense, technical product surfaces feel simple.

Preferred

• Comfort reading code and documentation, and front-end literacy (HTML / CSS).
• Prior work on dashboards, consoles, or documentation experiences.
