Options market making

You build the software that sends a market maker's option prices to the exchanges and keeps them correct, as a Lead Software Developer at Squarepoint Capital. The seat can be based in New York, Montreal or London and covers options on shares traded on United States markets. A market maker quotes a price to buy and a price to sell, all day, on every option it covers, and an option is a contract giving the right to buy or sell a share at a set price by a set date. Each share has options at many strikes, the set prices, and expirations, the end dates, on several exchanges, so the firm must keep a very large number of quotes alive and correct at once.
