Senior Frontend Engineer — TypeScript & Performance

Role at a glance

Make the app feel fast where users actually feel it.

Nimbus Creative (demo) ships a design-heavy editor on the web. You will own cold start, interaction latency, and bundle size—not “paint it green in Lighthouse on a $3k MacBook” theater.

What you will do

• Profile real sessions: RUM by device, geography, and entry route; kill regressions in CI with perf budgets and filmstrip diffs
• Collaborate with design: fewer blocking fonts, better skeletons, and motion that respects `prefers-reduced-motion`
• Harden the editor: undo stacks, large-doc rendering, and virtualization that do not desync the canvas

What we need

• 5+ years shipping advanced TypeScript UIs, including performance and accessibility
• You can explain hydration trade-offs and your decisions around server vs. client data fetching in specific terms

How we will interview you

Code walkthrough of a real perf regression you fixed, a live session optimizing a page we give you, and a collaboration exercise with a designer on a real constraint.
