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 an eight-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. 


  • Participate in the full development life cycle, including design, implementation, quality testing, and release.
  • Leverage your strengths and interests to work on full feature implementation from high-scale concurrent processes, to security and network traffic, to system development and services APIs.
  • Develop and optimize high-performance data aggregation and analysis pipelines at scale.
  • Gather test data, implement unit tests, develop integration tests, apply testing frameworks, and evaluate end-to-end outcomes. 
  • Minimize errors and repetitive human effort with automation.
  • Mentor other engineers, perform code reviews, and suggest improvements to tools and processes.
  • Work in close cooperation with the Product team to deliver innovative solutions, optimize the existing systems, and add new features.
  • Join a growing global engineering team and use your technical skills to drive value and impact business decisions.

  • Our Tech Stack
    We have a principle-based approach to our tech stack. We choose tools and platforms that help engineers develop and test code quickly, and that we can support across the organization over the life of the product. Time to market is critical for our customers in this digital economy.

  • Python: Effective choice for engineers and data scientists to implement models quickly.
  • MongoDB: Fast, scalable, and efficient NoSQL database solution.
  • Go: Highly performant for high-throughput, low-latency services.


  • 8+ years of experience as a Software Engineer.
  • Strong foundation in programming, algorithms, and software application design.
  • Solid understanding of RESTful systems and the principles of good API design.
  • Solid knowledge of one or more modern software languages (Go, Scala, Java, C++, C#, Ruby, Python).
  • Interest in working in Sensor Tower Tech Stack.
  • Excellent written and verbal communication skills.

  • Preferred skills
  • System software development.
