Fulfil Your Potential With Us
Sensor Tower has a successful startup environment, so engineers can take advantage of working on a variety of projects, owning major features that impact customers, building new things, and productionizing the experimental code that has proven value. 
We need engineers who have the creativity and skills to gather meaningful data and insights. In our lean and flat organisation, you will also have a meaningful say in what and how we build out all aspects of our product. 
Unlike many startups, we have a nine-year track record of profitable, double-digit growth, so that financial stability allows engineers to focus on the interesting problems we’re solving rather than company viability. It also means we can invest in impactful ideas and quickly react to market changes.
