Job description

We’re looking for recent experience with pureReact+Typescript, with best practices from React 18 (like no Classical components or Classical HOCs). Frameworks on top of React (like NextJS) aren’t what we’re looking for.

No frameworks. NextJS and other frameworks “on top” or React are more a minus, than plus.

• Candidate should have recent experience with Redux and Redux Sagas specifically (not alternatives like Zustand and other state management libraries).
• It can be ReduxJS Toolkit (also known as RTK), but I will get deep into what it solves and why, and how it works. We’re not leveraging RTK too much in our code base.
• Candidate should have experience with working/creating/maintaining basic components (buttons, dropdowns, layouts, etc)without any 3rd party librarysuch as Chakra, MUI, Antd, or others.
• They ought to be experienced with “styles-in-JS” pattern using either styled-components, oremotion/styled. Preferably including advanced patterns like custom themes, theme mapping and wrappers, mobile responsive components, things like these.
• Experience with latest data routing fromreact-router-domis a plus, but not a deal breaker
• Experience withmono repositorieswill be a plus (NX workspace is a huge plus), but not a deal breaker
• When I’m sure they’re familiar enough with things listed above, I WILL ask about architecture layering, it’s “why” and “how”.
• Practiced ownership over their engineering decisions, and being exposed to the autonomy and decision making outside of “what CSS style to apply here”
