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 60 million locations globally and have managed over 3 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 Internet Service Providers (ISPs) 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.
This is a work-from-office / In-Office role based in our Hyderabad, India location.
Plume’s Integration Engineering team is looking for a bright and ambitious Firmware Engineer to continue delivering industry-leading innovation for large-scale ISP solutions at a rapid pace.

In addition, you will provide end-to-end solutions that involve CPEs with OpenSync embedded in the cloud platform and beyond. This is a high-impact and customer-facing role with immense growth opportunities and will truly put your software engineering skills to the test.
What You’ll Do
Participate in all stages of the software design lifecycle working in multi-disciplinary teams spanning cloud, embedded devices, front-end web/mobile, data, and product
Interface with the customer on a regular basis and understand their problems and surgically solve them in any software layer possible
Write clean, maintainable code, and perform peer code reviews
Solve challenging scale, integration, and architectural problems
Deploy, operate, and troubleshoot applications in a Kubernetes ecosystem

What You’ll Bring

5+ years of industry experience in writing production code in multiple areas of a product
High proficiency in writing idiomatic code with experience in C/C++
Thorough understanding on L2/L3 and L4 Networking Layers and 802.11.
Experience working on WiFi access points, operating systems such as OpenWRT, open source platforms such as RDK or OpenSync is a plus
Strong understanding of algorithms, data structures, object-oriented programming and embedded systems
Fundamental understanding of computer networking, operating systems, and databases
Strong analytical and problem-solving skills
Strong oral and written communication skills
About Plume
As the creator of the only open, hardware-independent, cloud-controlled experience platform for ISPs and their subscribers, Plume partners with over 400 ISP customers, including some of the world’s largest such as 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 ISPs to decouple their service offerings from hardware and rapidly curate and deliver new services over a multi-vendor, open-platform architecture.
