3.软件工程师 Software engineers

What would all that planning and design by network and data analysts be worth without software? Not a whole lot, which explains why the BLS expects the cadre of software engineers and application developers to swell to 689,900 by 2018 (up from 514,800 in 2008). Whether they are building business software, constructing an operating system, developing games, or designing mobile apps, software engineers have a wide array of career avenues to consider.

如果没有软件，网络规划设计师和数据分析师又有什么用？这也就可以解释为什么劳工统计局预计到2018年软件工程师和应用程序开发人员将增长至68.99万人（2008年这一数字为51.48万人）。不管软件工程师开发商用软件、操作系统、游戏还是手机应用程序，他们的职业道路都很宽。（下图：旧金山谷歌I/O开发商大会上参观者尝试新应用程序）

And it surely does not hurt that the worldwide smartphone market grew by 50% between the second quarter of 2009 and 2010, according to the market research firm IDC. The impressive growth of the smart mobile industry over the past few years will only add fuel to the fire of the impressive job prospects for application developers, as smartphone users have come to expect increasingly advanced software applications to justify the increased expense of their phones.

根据市场研究机构IDC（互联网数据中心）的预测，2009年第二季度至2010年之间全球智能手机市场增幅达5成。过去几年中智能手机行业这种迅雷不及掩耳的增长幅度将会给应用程序开发人员的职业前景添砖加瓦，因为智能手机用户越来越希望能有高级的软件应用来匹配其高端的手机。
