STON.fi is a decentralized exchange (DEX) built on TON Blockchain smart contracts, enhanced with advantages such as low fees, low slippage, super user-friendly interface and direct integration with the TON wallet.

STON.fi:

implements one of the main features of cryptocurrencies — it facilitates financial transactions without any involvement of banks, brokers or any other traditional intermediaries;
utilizes the TON blockchain and is a natural part of TON DeFi’s growing suite of tools that make a huge range of financial services available directly from the TON cryptocurrency wallet.

We are looking for a new frontend team member who will be immersed in the process of working with TON Blockchain and its unique features; will help the present team in bringing new complicated business scenarios to life and upgrading the current application. That is a very interesting role because you will deal with new standards of the blockchain that emerge every month while developing the app that is already live and has a very big userbase - so naturally there are a lot of challenges for engineers to jump into.

What you’ll do:

Immerse in the context of business requirements and operation of the application scenarios; communicate in an open community of users and partner developers.
Produce typescript code that is easy to read, testable, supported, and framework independent.
Be responsible for a critical functionality that influences people a lot.
Build interfaces with mobile first approach and accurately following the design requirements.
Write unit test using vitest, e2e and integration tests using cypress.
Optimize application performance: deal with profiling, analysis and reduction of problem spots, refactoring.

Requirements:

Strong knowledge of javascript (ES6+), typescript.
Ability to make adaptive interfaces using css/sass.
Expertise with the react framework and its ecosystem.
Location that is close to CET timezone, as that's where most of the team is and most of the work is getting done.

Bonus Skills:

Experience with frameworks other than React.
Expertise with themization and localization implementation;
Experience in developing and supporting CI/CD workflows with gitlab and docker as well as maintaining versioned application releases.
