Life at Plume

At Plume, we believe that technology isn't about moving faster, it's about making life’s moments better. Which is why we’ve built the world's first, and only, open and hardware-independent service delivery platform for smart homes, small businesses, enterprises, and beyond. Our SaaS platform uses WiFi, advanced AI, and machine learning to create the future of connected spaces—and human experiences—at massive scale.

We now deliver services to over 50 million locations globally and have managed over 2.5 billion devices on our platform. We’re expanding rapidly, pioneering a new category, and we achieved our Series F funding in just four years. Our customers include many of the world's largest Communications Service Providers (CSPs) who look to Plume to help them evolve their smart home offerings while gleaning insights from their own data. 

With a bias for action and a love for being trailblazers, the team at Plume embodies a combination of relentless curiosity and imaginative innovation. We challenge ourselves to think in ways that other companies don't, work to do what should be done (rather than what can), and if we can’t do it exceptionally well, we don’t do it. It’s how we've assembled a team of world-class builders, thinkers, and doers. And it’s how we’re reinventing what’s possible every day.

Plume crafts new services built on top of the world’s best performing home WiFi system. Plume’s web-based tools are critical parts of those customer and partner journeys, including internal tools that provide a variety of utilities, insights, and data visualisations to assist our engineering and customer support teams, as well as our ISP partners.

We’re looking for a front end developer to work on our suite of web applications. You will be expanding the tools with new features, maintaining or improving existing features, creating new applications and updating application frameworks and architecture.  Our applications are mostly developed in React Typescript frameworks and a small set using Angular. It is expected you have significant professional experience in one or more of these frameworks, and the desire to be exposed to and learn across all frameworks. As a member of a small and integrated team we cover a lot of ground and you will have a deep impact on how the world sees Plume. We're looking for staff which can run autonomously and can step up to lead a product feature and accept the ownership of front end application delivery of one of our products.

About Plume

As the creator of the only open, hardware-independent, cloud-controlled experience platform for CSPs and their subscribers, Plume partners with over 350 CSP customers, including some of the world’s largest such as Comcast, Charter, Liberty Global, and J:COM. 

Using OpenSync, the most widely supported open-source, silicon-to-cloud framework for smart spaces, Plume’s software-defined network allows CSPs to decouple their service offerings from hardware and rapidly curate and deliver new services over a multi-vendor, open-platform architecture.  

Backed by investors such as Insight Partners and SoftBank Vision Fund 2, Plume is now valued at $2.6B, having added over $500M in funding in 2021 alone.
