Flow traders: People who buy and sell financial products on behalf of a bank's clients.

Proprietary (or 'prop') traders: A select group of elite traders who are given licence to trade with the bank's own money.

Execution traders: Traders who do little else than place trades on behalf of analysts and fund managers.

Sales traders: A kind of hybrid between salespeople and traders - they recommend products to clients and then execute the trades resulting from their recommendations.

Trading roles have been profoundly influenced by the rise of technology over the last decade, but investment banks also recruit for separate electronic trading divisions.

The introduction of electronic trading has dramatically reduced trade execution speeds, along with the cost of transactions, and that there's increased transparency in the markets. The use of algorithms - computer systems which decide on price, timing and quantity of an order - also meant that the average trade size fell.

The emergence of automation transformed the market from one where a great deal of human-intermediation was required into one where computers largely do the work in executing and processing trades. As a result a larger number of traditional trading roles were eliminated; however, electronic trading has also created a range of new positions and careers in trading.

These new finance jobs in trading include:

Quantitative analysts: Quants are maths geniuses, and they are the key to gaining an edge in e-trading. Quant jobs include designing, developing and implementing execution algorithms using a mathematical approach to identify investment opportunities and strategies in the market.

Consultants: A consulting job is all about keeping clients satisfied. Consultants run various statistical reports, including transaction cost analysis and trade reports, to ensure that clients are using trading tools in the most effective way. Consultants also offer tips on how to improve performance.

Sales traders: It's the sales trader's job to facilitate the execution of trades for clients, while also offering a menu of the bank's e-trading products and facilitating a customer's decision on what is the best one to suit their needs. It's a combination of marketing and client relationship management. Banks also hire for pure sales roles.

Market structure jobs: This is a research-led role; market structure professionals analyse upcoming regulatory changes and macro trends and their potential effect on the trading environment.
