Software Engineer - Wireless/IOT


Because you belong at Twilio

The Who, What, Why and Where

Wireless is the IoT business unit at Twilio. The Twilio platform enables companies to integrate communications directly into their applications via simple cloud API’s and with on-demand global reach. Twilio abstracts away a world of complexity so that our customers can go global without concern for managing a global communications network, carrier integrations and relationships throughout the world.

As a Software Engineer in the Wireless organization, will be responsible for the delivery of software from concept to production deployments and monitoring. You will work on the implementation efforts alongside a team of seasoned and junior engineers. Once deployed, you will be responsible for helping customer support assist and troubleshoot problems as they pop up in the field. To take it to scale, you will be managing a complex distributed platform with points of presence globally and will be concerned with availability, throughput, latency as well as real-time considerations. There will be some data components so you will be working with distributed SQL and NoSQL databases and caches. At the core are cloud technologies that enable deployment and management of computing resources globally.


Twilio is looking for a leader with a demonstrated track record of shipping services to production. Skills we are looking for include:

  • 2+ years of developing software on the JVM, either Java or Scala.
  • Experience working on distributed systems and service-oriented architecture, ideally in a Cloud environment.
  • Experience with either SQL and NoSQL data stores, ideally both.
  • Knowledge of the entire Software Development Lifecycle.
  • Hands-on experience running services in production is a strong plus.
  • The ability to communicate well- in person, on paper, or in code. You can explain technical concepts to product managers, other engineers, and support.
  • A Bachelor’s degree or equivalent in Computer Science or a related field.


As a Software Engineer, you will:

  • Collaborate with Product Managers, Architects and Engineering leaders to define, architect and build new customer-facing features.
  • Build new features.
  • Architect new systems and design APIs with a focus on scalability, testability, and maintainability.
  • Own, operate, and maintain your team’s services in a distributed production environment. Employ Agile methodologies to continuously deliver value to customers.
  • Drive quality by writing unit, functional, load and performance tests.
  • Design services that are reliable, scalable, manageable and supportable. Develop diagnostic and troubleshooting tools made available via our developer portal and to our customer support organization.
  • Lead architecture, design and code reviews as well as mentor junior engineers.
