Keemotion has three open positions.

The Brooklyn Navy Yard-based Keemotion makes a motion-tracking camera system for sports venues that enables games to be broadcast without a production crew. Its CEO, Milton Lee, previously worked for the Brooklyn Nets.

Last year, the company closed a $3.6 million Series A round, and its list of investors includes some high-powered names in the sports world. Among them: the Los Angeles Dodgers; David Stern, the former NBA commissioner and David Blitzer, co-owner of the Philadelphia 76ers.

Now the sports startup is looking to hire, with open positions in video production, operations and engineering.

Position Development is looking for two engineers.

The worker-run software company is looking for a ruby on rails dev and a polyglot dev to help in its work of building software for leftist and independent media companies. Its clients include Jacobin, The New Inquiry and Dissent. The company also asks for just 30 to 35 hours a week of work, which, it notes, is work and not an act of love.

uPort is hiring for a designer, a manager and an engineer.

uPort is working on one of the most ambitious projects conceivable in the blockchain ecosystem: decentralizing one’s identity.

Cofounder Rouven Heck wants uPort to be a sort of virtual passport on the blockchain. Personal information and data could be stored there and accessed and released only by the user, rather than by third parties like Facebook, healthcare providers and even the government.

Last month, we named it one of the top 10 Brooklyn blockchain startups you should know about.
