The Challenge The core of Sefaira is a cloud-based technology platform which implements highly parallel physics algorithms, for which Sefaira has a number of patents pending. We deliver solutions to problems that have traditionally been solved only in a fat client and which typically take substantially more time than our algorithms to execute. Your role will be to help us build out this technology platform. You’ll be working with our agile, world-class, architects, back-end and UI development teams to help you achieve this goal. The role offers the challenge of creating software systems that have the simplicity and flexibility to solve our customers’ present problems and provide the reusable foundation to solve their future problems. In short, this position is an excellent opportunity to join a young software business with a big mission and plenty of growth ahead.

Location This full-time position is based in New York City or London, England. We offer a competitive salary, benefits package and excellent work environment. We’re located at Union Square in New York City and at Piccadilly Circus in London.

Development Environment Client Side: HTML5, CSS, OO JavaScript, AJAX, and Ruby Server Side: Linux, PostgreSQL, Scala, Tomcat+Spring+Hibernate+Java, node.js, and C++ We also use: memcached, virtualization, RESTful APIs and open source tools

Remuneration We are here to build for the future – not to cash out today, so besides a fair and performance based salary, benefits and vacation, your package will also include an equity component.
