Rust developer needed to create API connectors (cryptoexchanges)

We are trading company. We are looking rust developer to help us developing our trading infrastructure. The task is to develop two gateways (connectors). The gateways will interact with crypto exchanges and trading infrastructure. For each gate, we need to implement:

restAPI:
- adding, removing exchange orders
- modification of the price of an existing order (if supported by the exchange)
websockets:
- getting stock balances, locked / available balances
- getting deals from accounts
- getting market prices
- getting liquidation prices

Technical documentation on request.
