Due to growth in its outsourcing business and a variety of industry changes, Mercer has flagged plans to hire more than 100 staff.

"Given the series of recent large outsourcing wins, we're in a strong hiring phase and are attracting some great people to complement our existing talent pool. We're always looking to add unique skills and experiences to our team," Mercer Asia-Pacific outsourcing business leader David Anderson said.

Mercer is searching for super business analysts and project managers for its Sydney and Melbourne offices. The firm is also searching for a member services and advice leader after the departure of Scott Walters.

In the last two years the outsourcing business, which includes the Mercer Super Trust and administration of standalone corporate plans and multi-employer plans, has seen a 63 per cent growth in members under administration and expects a further 53 per cent growth between 2010 and 2012.

Mercer also expects member contributions to increase by approximately 90 per cent between now and 2012.

"This growth, along with industry changes such as the implementation of modern awards, the continuous effect of choice of fund, and the likely implications of the Cooper review, have led to a shift in emphasis for Mercer," a company statement said.

"Its business focus has shifted towards member acquisition and development, with a focus on the increasing competitiveness of the superannuation system in Australia."

Mercer is aiming to create a stronger link between marketing, member services, and financial advice and new products.

"We aim to manage and retain members for their lifetime by adding value to them in terms of their superannuation savings, experience and education regarding their retirement incomes," the statement said.
