Last month we featured five startup job opportunities that sounded awesome. These included Wistia’s Director of Customer Happiness, Performable’s Software Engineering position, Locately’s Founding Software Engineer position, Blank Label’s Dumbledore of Marketing, and SCVNGR’s Ruby on Rails developer opening. Back by very popular demand, this month we’re featuring another set of startup opportunities that separate themselves from the pack.

It was much harder to narrow all the opportunitites down to just five this month given the sheer volume of how many startups are hiring (and especially hiring developers) — a sure sign of the incredible new economy that’s developing here in Massachusetts (which we will be celebrating next week and invite you to join us, too!).

Social Media Specialist

Cambridge-based Carbonite, backed with over $65M in venture funding, may be gunning for its IPO later this year. Since launching its online backup service in 2006, the company has enjoyed triple digit growth in revenues and customers each year. Last year the company was ranked #9 on the Inc. 500 list of the fastest-growing companies in America (#1 in the tech category), on top of being named one of the best places to work by the Boston Business Journal. More recently, they were named a finalist for the Red Herring Global 100. Their Twitter following is over 4,000 and Facebook fans number nearly 6,000, and as a social media specialist you’ll be interfacing with and growing both on a daily basis.

Consider yourself a digital native and want to flex your skills in a startup gone big? This job’s for you. According to their post, “This person will develop social marketing plans and content strategies and will have the unique opportunity to be the “voice” of our brand via social media channels.” Great opportunity? We think so, too.

Front End Engineer

Love Facebook? Nanigans is generating some serious buzz right now with its pay for performance Facebook ad service, and is looking to expand its team. We work in the same space as Nanigans, and can vouch that you’ll be working with a high energy team with their eye on the prize. The company’s secret sauce “makes your social ads fly,” and as a team member you’ll be working to build more innovative ad products for the social media world. Want to play a leading role in this quickly growing company we named one to watch in 2011? Perks include unlimited snacks, being able to play Facebook games, have dev sprints timed with a potato-powered clock, and make structures out of the 100+ empty Big Gulp cups under the CTO’s desk.

According to their posting, “We strive to hire the best and in return offer the best. As a team member you will create new, easy to use innovative tools to conquer the challenges of the social advertising market.”

UI / UX Web Designer

peerTransfer, born out of MIT, is looking to take its platform to the next level and a be a leader in the future of payments. The company is making it cheaper for you to send money internationally, and is starting by targeting the college market where parents regularly send money across borders. We just featured the company as one of 6 startups putting Boston on the map for payments, and you can help by leading the platform’s UI/UX and making a lot of people across the globe happy. Perks include “substantial equity,” that the company also has an office in Valencia, Spain (ven conmigo?), and lives and breathes some awesome values. The company locked down $1.1M this October from Spark Capital, Project 11 and a group of Super Angels including personality Dave McClure.

According to their posting, “You not only work in web design but you breathe it, being aware of the latest UI trends, tools and processes. You’ll be directing the visual appearance of all new features and enhancements.”

iPhone and iPad Developer

Social shopping promises to be hot in 2011, and Svpply is hoping to lead the way with its follow model and selection of cool products. The company moved to Boston in November after a $550k seed round led by Spark Capital. The site was co-founded by serial entrepreneur Zach Klein, who also built the video platform Vimeo, CollegeHumor.com as well as Busted Tees. Klein is a partner at Founder Collective, where he has invested in well known consumer companies like Flavors.me, HotPotato (acquired by Facebook in August), Venmo and picplz. Guy is the word on consumer products, so what iOS developer wouldn’t want to take advantage of building an iPhone and iPad app for his newest project? Or rather, who wouldn’t want to build the future of product catalogs?

According to the posting, “We want to Svpply to be tactile and optimized for touch devices, but most importantly we want expertise for developing the next generation of product catalogs. Join us as our handheld leader and use our data to build a rich and remarkable companion to our Web app.”

Online Acquisition Marketing Specialist

WordStream is helping put Boston on the map for the future of marketing with its marketing software. The company offers a variety of free and paid products for small and medium businesses that automates most of the manual work involved with creating and optimizing paid and organic search. Founded in 2007, the company raised a Series B in May of last year, bringing their total funding to $10M. The company is continually listed as having one of the best small business marketing blogs and Twitter followings, and as the online acquisition marketing specialist (albeit the title is a bit much to say three times fast) you’ll be a prominent face there dropping marketing knowledge to businesses across the globe.

According to the posting, “You will own and drive results across marketing programs (webinars, white papers, tradeshows, company blog, speaking engagements, email nurturing campaigns, and online community/social media) and develop world-class marketing collateral (brochures, sales presentations, website content/experience).”
