HN Jobs

London, UK - Osper We provide a real prepaid debit card for young people, aged 8 - 18, so they can make their own decisions with money: in shops, online, at ATMs, and abroad. Thousands of children have already signed up to our service. But we not only give debit cards to young people - we are building a highly automated financial system that gives them unparalleled service. Behaviour-based security measures. Using and contributing to the best of open-source tools. Fully automated continuous integration and deployment. Hackathons to build the next big thing - what is that exactly? That's up to you. We want to meet and work with geeks of all stripes - from sysadmins to server-side devs, testers to mobile coders, data crunchers to security analysts - with a broad and deep set of relevant skills. Some examples appear below but we're excited to talk with you no matter what your technical profile is. Back-end developer * Writing well-tested, readable, robust code in any modern programming language. (We mainly use Python, but don't worry if you know something else better.) * Designing semantically meaningful, self-documenting, intuitive APIs, especially for server-to-mobile interaction. * Integrating with sloppy, poorly-documented, sometimes buggy APIs from vendors - and hiding the mess behind a clean interface to simplify everyone else's job. * Building and extending a database schema that's meaningful, readable, and fast. * Developing financial applications of any kind (but payment processing and PCI compliance win bonus points). Front-end developer * Designing and building amazing mobile and responsive-web experiences using HTML, CSS, and Javascript. Extra points for native app experience, especially with PhoneGap. * Consuming APIs on a mobile device - and contributing to their design and improvement. * Automating tests for mobile applications. * Using the top tools for elegant, beautiful front-end design and coding - we're currently fans of SVGs, web fonts, and Photoshop.
