Vonage Engineering Mission: Vonage London is the emerging leader in the $100B+ cloud communications platform (CPaaS) market. Customers like Airbnb, Viber, Whatsapp, Snapchat, and many others depend on our APIs and SDKs to connect with their customers all over the world. As businesses continue to shift to a real-time, customer-centric communications model, we are experiencing a time of impressive growth.

Why this role matters

We need Full-stack Developers for Web Applications (75% server-side Java and 25% front-end JavaScript) to work with our team in our modern London office, situated close to Old Street tube station in the heart of Tech City.

In this position, you will be responsible for working on two major web applications that are important to Vonage's business. One web application is customer facing; the other web application is internal, for staff use only. Java Developers collaborate with product management, UX/usability/front-end specialists, QA testers, and our internal users.

We use continuous integration and release software weekly. We follow the Kanban agile methodology and track our work in JIRA.

What you'll do:

  • Develop features for web applications within the world of cloud communications and APIs. That may include: sign-up workflow; payments and anti-fraud workflow; features to support our products (Messaging, Voice, Verify, Insight, Stitch) including powerful searches and debugging tools for our customers
  • Help champion a maintainable well designed Java server-side codebase and look for ways to further improve our applications’ internal design, thinking about build, deployment, object-oriented design, automated testing, error handling, logging, monitoring, et al
  • Creating responsive web pages with excellent usability, working in collaboration with the team’s UX/usability and front-end specialists
  • Working on two major web applications that are essential to Vonage's business
  • This role is predominately Java server-side, and there is also a front-end aspect (JavaScript, JQuery, CSS3, and HTML5 generated by JSP). The split of time is approximately 75% server-side and 25% front-end

What we value:

Being disruptive. Getting things done. With smart people. Enjoying knowing that the work we do is having a global impact by enabling never before imagined communications.

We have big goals, and we want the people who join us to be self-confident, focused on customers and delivery, and who are structured and committed in their approach. We iterate quickly, we fail fast, we take smart chances. We value those who will help us continue this spirit

Values matter at Vonage. We are on a mission to bring value for consumers and enterprises through global cloud based communications.

But just as important as delivering value is how we deliver that value.

We believe in integrity. Both personally and professionally. We believe in empowering our employees and are actively seeking entrepreneurs in training who want to help build something larger.

We have gotten to this point by being committed, passionate, and focused on getting things done. We need more people like us. If this appeals to you then we encourage you to apply.
