  • You have experience integrating solutions into a complex web service & mobile application ecosystem

  • Emphasis on building maintainable, well-tested and resilient solutions.

  • Passion for staying abreast of the latest research, and an ability to intuitively understand highly technical publications and judiciously apply novel techniques in production.
