About this role:

A Day in the Life:
Interviewee: Engineering Team Lead - Sasha Yelkovenka
What does your day to day look like working as a Software Engineer?
I work with tons of data and the volume of this data is constantly increasing. My job is to make sure our customers can access it as quickly as possible and provide them convenient tools for data consumption. I love the spirit of taking ownership of your work and product.
How do you collaborate with your team as a remote employee?
Sensor Tower has a great atmosphere of a distributed team. We often pair over zoom to combine our knowledge in order to achieve better results..
What You Will Do
Participate in the full development life cycle, including design, implementation, quality polish, and release. Leverage your strengths and interests to work on full feature implementation from brainstorming the architecture design, all the way to the back end implementation and delivery to the customers. Optimise endpoints that touch billions of rows in the database, by applying profiling to ruby code and understanding crucial performance details of ClickHouse queries. Perform code reviews, and suggest improvements to tools and processes. Work on challenging products like SDK Insights, where you not only need to develop a robust back-end, but also understand how mobile SDK teardown works.

Experience We Want To See
3+ years of experience as a software engineer (If you have lesser years of experience but have meaningful github contributions and other coding samples, this will be taken into consideration). Strong foundation in programming, algorithms, and software application design. Solid understanding of RESTful systems and the principles of good API design. You have an understanding of the basics of cloud environments, and ideally you’ve had some exposure to AWS. Required: Ruby on Rails (or Python and willing to learn Ruby on Rails). Nice to have: Clickhouse, MongoDB, Sidekiq, TypeScript, React.js.
Our Engineering Culture
We believe that "Simplicity is a prerequisite for reliability." We are looking for engineers who align with our core values:
Simplicity: We avoid over-engineering. We prefer the tools we already have and the most straightforward solutions over "shiny new toys." Quality: We write code that is a pleasure to read because we know code is written once but read many times. We don't cut corners, and we polish to a high level before shipping. Extreme Ownership: We don't just do the minimum. We expect you to understand the "why" behind your work and own the ultimate goal of fixing problems at their root cause, avoiding temporary band-aids. Prioritization: We focus relentlessly on what is important, not just what is urgent.
