Front-end Engineer


Particle is hiring an experienced front-end developer to build amazing interfaces that simplify the creation, roll-out and management of internet-connected hardware products.

From writing firmware code in your browser, to updating thousands of devices over-the-air, or easily sending massive streams of telemetry data to 3rd party services, great interfaces are a major reason why Particle has the largest developer community in the Internet of Things (IoT) with over 120,000 engineers and hundreds of companies building IoT products on our platform.

As a front-end engineer at Particle, you will work with a global technical team to create the next generation of web applications to meet the needs of our rapidly growing customer base. You will build developer tools that make it easy to bring a connected product to market, in addition to management interfaces that allow enterprise customers to monitor & control devices in the field. Are you hungry to learn back-end skills? You will also have opportunities to work on the services and APIs that your front-end apps interact with.

Are you creative, curious, and analytical? Do you have strong empathy for customers and a passion for user experience? Do you bias toward shipping and delivering value to customers quickly and iterating over time? If so, join our team! Particle is a fast-growing startup in a young and evolving industry, so you should be self-driven and comfortable with uncertainty. You should love overcoming challenges and solving problems for customers.

Some of the applications you may work on include:


  • Create and improve front-end interfaces and tools used by Particle customers
  • Work with existing code bases to increase developer happiness by improving the design of the code and the tooling
  • Collaborate with product managers and designers to sketch out new features and translate mockups into working front-end applications
