We are currently building the next generation of our HTML5 based financial trading applications and are looking for a lead front end developer that can help us by providing technical leadership and consistent technical direction that will allow us to fulfill the aim of delivering an unparalleled user experience in our business domain.

With a specific focus on low latency, reliability (100% uptime, 24hr/5.5days), scalability and the potential for an order of magnitude growth in load and volume, our platforms currently support:

  • 10s of thousands concurrent clients globally
  • 100s of thousands of price updates per second
  • Thousands of trades and orders per second
  • Trading applications for multiple platforms and form factors.

So, have you built a JavaScript framework or heavy performance critical JavaScript applications before? Did you stop using JavaScript libraries and frameworks because you started building your own? Are you an expert in browser technologies? Are you interested in working in an international team with a passion for compelling, functional and easy to use interfaces? – then you may be the right candidate for us.


You will:

  • Be a key contributor in defining application architecture and development flows.
  • Design, prototype and implement an application framework using the latest JavaScript and HTML5 technologies
  • Develop with the latest HTML5 web technologies such as CSS3, JavaScript, SVG and Canvas.
  • Work with product managers, UX designers, and Front End developers to design and deliver user experiences that work flawlessly across all major desktop and mobile browsers.
  • Ensure reliability, scalability and efficiency
  • Work in a dynamic team oriented environment using agile methodologies. Our objective is to deploy every day and learn on the way
  • Assist and mentor less experienced front-end engineers, leading them to excellence
  • Conduct design and code reviews
  • Provide estimates for development activities based on working knowledge and real world experience.
  • Keep abreast of front-end development techniques and technologies


  • 3+ years of experience developing large-scale, performance critical web applications and real-time data-driven interfaces
  • Relevant experience in developing JavaScript frameworks and heavy JavaScript applications with HTML5/CSS3
  • Experience writing native JavaScript without the use of a framework
  • Experience designing and developing for multiple form factors (mobile/tablet/desktop), across multiple platforms (Win/OSX/iOS/Android).
  • Experience integrating front-end code within a server-side view layer (.NET, PHP, Ruby etc…)
  • Mobile and desktop web performance & optimization knowledge (e.g. sprite sheets, icon fonts, performance profiling).
  • Javascript Unit testing experience (Mocha/Jasmine/etc)
  • Experience creating documentation and well-commented code
  • Experience and interest in implementing and maintaining efficient workflows with package managers, asset pipelines, automated testing, build system and version control.
  • Familiarity with mobile first development and responsive design.
  • Expert knowledge in browser technologies
  • Creative self-starter with great team and cross-group collaboration skills.
  • Excellent verbal and written communication skills.
  • Have outstanding attention to detail and a strong sense of ownership
  • Prior business knowledge or willingness to learn quickly about the financial industry, preferably electronic trading.


  • A rare opportunity to join a highly skilled and motivated team working with the latest web technologies at scale across multiple platforms within the financial industry.
  • The chance to strongly influence a highly visible project from the outset, one that will form the public face of Saxo Bank’s next generation trading platforms over the long-term.
  • An opportunity to work as part of a dynamic, very ambitious and, at the same time, informal and pleasant working environment.
  • Encouragement to learn and grow your interests, wherever they lead.
  • An organisation that values innovation, i.e. by having FedEx Days
  • An attractive salary plus benefits package.
