Job summary

Aviy is hiring a frontend engineer to ship features in React and TypeScript, owning performance as the product scales.

You will ensure accessibility, keyboard navigation, and screen-reader compatibility, while shaping a shared component library and maintaining test coverage that protects invoices. The role is fully remote with UK/US eligibility and a strong emphasis on shipping quality UI.

Qualifications

• Four or so years writing production React with strong TypeScript.
• Real accessibility knowledge — focus management, semantics, contrast.
• Interest in fast, well-made UI and thorough testing.
• Taste for polished transitions and useful error states.

Responsibilities

• Build product features in React and TypeScript from design to shipped detail.
• Maintain performance as the app grows and justify it with data.
• Ensure every flow is keyboard-navigable and screen-reader friendly.
• Shape the shared component library with design.
• Write tests to prevent regressions affecting invoices.

Job description

A lot of our customers run their business from a phone. They are invoicing from a van, between appointments, on a site with one bar of signal, often at the end of a long day. That is the real constraint on this job, and it is a more interesting one than it sounds.

You would build the product surfaces in React and TypeScript, and own whether they stay quick as the product grows.

The work

Day to day:

• Build product features in React and TypeScript, from the design file through to the shipped detail
• Hold the line on performance as the app grows, and prove it with numbers rather than impressions
• Make every flow keyboard-navigable and correct for a screen reader
• Shape the shared component library alongside the design team
• Write the tests that stop a regression reaching someone’s invoice

What we are looking for

Four or so years writing production React with strong TypeScript. Real accessibility knowledge — focus management, semantics, contrast — not a plugin you ran once.

We would love to see something you made fast that used to be slow, and hear how you knew.

Taste matters here too: the transitions, the optimistic update, the error state that tells someone what to do next rather than what went wrong.

Where you work

This one is fully remote. We care where you are only insofar as the law does: you need the right to work in the UK or the US already, because there is no office attached to this job for us to sponsor you into. Beyond that, work from wherever you work best.

We overlap a few hours a day and write the rest down. Most decisions live in documents and pull requests rather than meetings, which is partly a philosophy and mostly a consequence of being spread across time zones.

Pay and the rest of it

$95,000–$135,000 a year, reviewed every year against the market for where you live, plus share options — everyone here owns a piece of the company.

Flexible hours, a budget for whatever laptop and desk you actually want, an annual learning budget, generous paid time off that we check people take, and paid parental leave for every parent however you become one.
