Ambush is a People Company. But what does that mean exactly? It means we care about our people as much as we care about building great products. We take a human-centered approach to identifying, retaining and integrating highly-talented, long-term remote people into America’s best product and development team. 

We began our consulting journey in 2015 and have been growing ever since! We do that by delivering best quality work possible for our clients. We are not afraid to take risks, and we always seek the best possible path to solve a problem, instead of just a quick makeshift solution. Thanks to our highly skilled team of engineers, we always perform tasks using our best abilities! 

We are passionate about what we do everyday, and we can always count on our team to have our backs. Teamwork is one of our core values! We don’t go anywhere by ourselves. We are driven to achieve great things. And we are extremely helpful to everyone. We expect you to be a team player. 

At Ambush, we have different initiatives to help you increase your knowledge and skills. Here you will be part of an English-speaking environment and work on a place where sharing knowledge is a core value! To exemplify it, we have an English Immersion moment for you to enhance your vocabulary and pronunciation. And we also have a special moment for people to present and share knowledge with their colleagues. These are a few examples of our dynamism when the subject is knowledge sharing!

Our interdisciplinary team of engineers makes use of what’s best in the technology world -  combining hardware, firmware, backend, frontend, machine learning and mobile development - to provide exceptional surveillance solutions to our clients.
Our systems process and aggregate information from various wireless sensors (IoT) in near-real-time in order to produce a final verdict (also known as “sensor fusion”) and, if necessary, deter intruders and alert our customers about any unexpected activity.
