  • The "Internet of Things" (IoT) is expected to grow to $19 trillion over the next 10 years as 50 billion devices are brought online. Aeris is at the forefront of this industry, building networks and applications to enable Fortune 500 clients like Chrysler, Honda and Bosch fundamentally improve their businesses. Headquartered in Silicon Valley with offices in Chicago, London, Delhi, and Tokyo as well as other markets. We rank in the top ten M2M operators globally, powering critical projects across energy, transportation, retail, healthcare and more.


    Our company is in an enviable spot. We’re profitable, and both our bottom line and our global reach are growing rapidly. We’re playing in an exploding market where technology evolves daily and new IoT / M2M solutions and platforms are being created at a fast-pace.  Aeris’ technology advantage starts with the purpose-built M2M core network, AerCore. 


    AerCore is built on hundreds of person-years of development, resulting in over 50+ patents. Importantly, Aeris maintains full control of the underlying technology within AerCore, enabling implementation of new market leading features and unique solutions that will continue to benefit businesses and organizations across the globe.  AerCore works across CDMA, GSM, and LTE networks, providing our employees continuous growth opportunities and development by gaining hands-on experience across all cellular and connectivity technologies.  

     A few things to know about us:


    • We put our customers first. When making decisions, we always seek to do what is right for our customer first, our company second, our teams third, and individual selves last.
    • We do things differently.  As a pioneer in a highly-competitive industry that is poised to reshape every sector of the global economy, we cannot fall back on old models. Rather, we must chart our own path and strive to out-innovate, out-learn, out-maneuver and out-pace the competition on the way.
    • We walk the walk on diversity. We’re a brilliant and eclectic mix of ethnicities, religions, industry experiences, sexual orientations, generations and more – and that’s by design. We see diverse perspectives as a core competitive advantage.
    • Integrity is essential. We believe in doing things well – and doing them right. Integrity is a core value here: you’ll see it embodied in our staff, our management approach and growing social impact work (we have a VP devoted to it).  You’ll also see it embodied in the way we manage people and our HR issues: we expect employees and managers to deal with issues directly, immediately and with the utmost respect for each other and for the Company.
    • We are owners. Strong managers enable and empower their teams to figure out how to solve problems. You will be no exception, and will have the ownership, accountability and autonomy needed to be truly creative.
