SDE 1- Web-First, Backend Capable - Java/JEE

Who we are

Zinier is a global company headquartered in San Mateo, California, with offices in Latin America, Singapore, Bengaluru, Australia, and Portugal and backed by leading investors including Accel Partners and Founders Fund.

We are passionate about our Vision

80% of the workers across the globe are Deskless. These are the people who keep our lights on and gas flowing, build roads and bridges, run our manufacturing factories, ensure that we get healthcare service, and provide us reliable phone and internet connectivity. As entrepreneurs, have we considered solving their problems and making them more productive?

If you are still reading, and connect compassionately about this underserved segment, come and join us to drive Technology Equity in the global workforce.

At Zinier, we are on a mission to enable these 2.7 B Deskless Workers achieve greater success for themselves and the world around them. Guided by a deep understanding of their needs, we design software experiences that enable every Deskless Worker to excel in the field.

Why we exist

Services shape how we live. Electricity lights up our homes. The Internet opens up our worlds. Cellular phones keep us connected no matter where we are. We take for granted the things we can turn on with the flip of a switch. But when even one of the services we depend on isn’t available, the day can quickly start to go sideways.

For organizations that provide these services, some of the most important work happens in the field — in neighborhoods, across open spaces, and along millions of last miles that criss-cross the country. Every moment of downtime matters, which is why Zinier exists. Zinier empowers organizations to work smarter — from the main office to the field — to solve problems quickly, fix things before they break, and keep people in the rhythm of their days.

To do this, Zinier has created a scalable platform powered by AI-driven insights and intelligent automation that helps field service teams work smarter, better, faster, and more efficiently. We help organizations automate routine tasks so the people in the field can focus on putting their expertise to work. We work with customers in telecom and energy.
