Administrative, Professional & Finance

Administrative professionals throughout the Financial, Engineering, Publishing and Media related industries are consistently needed. Over the past 20 years, these sectors have increasingly become early adopters of information technology. Amid the changes in the backdrop of regulatory environments, the industries will continue to heavily rely on computer-based systems (cloud-based included), which will need continual upgrades and maintenance, along with consolidation and innovation.

Financial and securities services firms are looking to better manage, hedge, and mitigate their risks by investing heavily in risk management systems; whereas fund managers are increasing IT spending. The world of insurance has changed a great deal, as well. New catastrophic threats, creating a business from e-commerce, and new lines of business all have evolved insurance technology departments into mission-critical resources while obtaining the most current and innovative technological solutions. They are also streamlining their data flow, as well as leveraging their database to better market to their clients and prospects. Data challenges such as updating, reporting, access, storage, and mining must all be considered when a data warehouse system is being selected.

Sigma provides employment service assistance with a variety of hard-to-find skill sets within Publishing & On-Line Media. Many businesses today are intensely interested in their users’ experiences and interactions, as well as ensuring their brand is well known and socially accepted.

Sigma does not knowingly direct its services or obtain information from children under age 13.

Most of this data is provided by you directly when you contact us, submit an application, attend an in-person recruiting event, through phone conversations, contact us about our services, or during your outsourcing or employment relationship.

We have set out further details below on the types of personal data we collect, store, and use and the reasons we use your personal data.

• Exceptionally it is necessary for vital interests relating to you or another person (for example, avoiding serious risk of harm to you or others); or
• It is necessary for our legitimate interests (or those of a third party) provided that our legitimate interests are not overridden by your interests or rights which require protection of your data.

• Exceptionally, where it is necessary for vital interests relating to you or another person (for example, avoiding serious risk of harm to you or others) and where you are not capable of giving consent; or
• Where you have already made the relevant personal information public.
• We will only use your personal information for the purposes for which we collected it, unless we reasonably consider that we need to use it for another reason and that reason is compatible with the original purpose. If we need to use your personal information for an unrelated purpose, we will notify you and we will explain the legal basis which allows us to do so.
