We are looking for energetic and experienced user experience developers who can add further skills and capacity to our world-class team.

The Challenge

You’ll help us design & build world-class user interfaces - whether web or mobile - which our customers (who are often non-technical) must find very intuitive, appealing and easy-to-use. 

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.

Development Environment Client Side: HTML5, CSS3 (LESS), JavaScript (AJAX, Dojo, jQuery, Backbone) Server Side: Linux, PostgreSQL, Scala, Java, node.js We also use: memcached, virtualization, RESTful APIs and many 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.

Essential Requirements

  • 7+ years of experience in object-oriented or functional UX design and development, with a strong understanding of encapsulation, MVC etc
  • 7+ years Javascript development experience, including frameworks, nuances, prototypical inheritance, etc
  • 3+ years experience of Agile/SCRUM/similar methodologies
  • Experience communicating design intent through mockups and wireframes
  • Ability to create prototypes to demonstrate proof of concept of a design

  • Experience with multiple programming languages and their strengths and weaknesses
  • Demonstrated ability to produce high-quality, high-performance, elegant, readable, maintainable and well-documented code
  • Ambition to be part of and help build a world class development team
  • A positive, entrepreneurial attitude that completes high quality projects quickly
  • Good Bachelor’s degree in Computer Science or equivalent, from a good university (Masters’ Degree or Ph.D. a plus)

Nice to haves

  • Understanding of functional programming
  • Experience with other languages (e.g. Java, Scala)
  • Experience with visual design software (Balsamiq, inDesign, Photoshop, etc.)
  • Experience with multi-threading, asynchronous communication and concurrency

About You

  • Egoless confidence
  • You are smart and get things done
  • Clear, justified communication to all stakeholders, from development, QA through product management to the CEO & CTO.
  • The ability to discuss openly and respectfully from high-level abstractions to detailed, specific flows and implications
  • Are self-motivated and have a driven personality, being responsible for your outcomes
  • Have the ambition to succeed and enjoy working in a stimulating team environment
  • Learn quickly and are passionate about undertaking challenges and seeing them through
