At Crowd Connected, we're leading the way in location-based technology, providing real-time tracking and insights that help businesses make smarter, data-driven decisions. By combining cutting-edge IoT with powerful data analytics, we're revolutionizing how organizations connect with and understand people in physical spaces--impacting everything from events to smart building management and beyond.


Our technology is built on a robust, AWS serverless backend and complemented by modern frontend applications. This combination allows us to deliver scalable solutions that are trusted by businesses around the world.


If you're excited by the challenge of shaping systems that power real-world impact, and want to join a collaborative, innovative, and ambitious team, we'd love to hear from you!

The Role

We're looking for a capable

Full Stack Engineer with a strong focus on backend development

, who can also contribute to frontend work. You'll play a key role in designing, building, and maintaining our AWS-based serverless architecture and Angular frontend applications.


This is a hands-on individual contributor role, best suited for someone who enjoys solving technical problems, writing clean, well-tested code, and working in a collaborative but lean environment.


We're particularly keen to find someone who can complement

existing expertise--bringing their own strengths while also being open to learning and teaching

. This role offers an opportunity to push boundaries and explore better or more efficient ways of doing things.
