Rally Health is all about putting health in the hands of the individual. It’s our mission, and it drives everything we do, which is to empower people with easy-to-use online and mobile tools that help them take charge of their health and health care, from improving their diet and fitness to selecting health benefits, and choosing the right doctor at the right price for their needs.

Our culture is built on a deep and sincere commitment to helping people live healthier lives. To do this, we are committed to innovating at every level. As our president and COO David Ko says, “We are a company that continuously innovates. It cannot end. It has to be in everything we do, which means that some of the things we’re going to do are not going to work – and that’s okay. We’re not trying to build something that is churn and burn. We’re building something that follows consumers over their lifetime.”

Rally Engineering is modern, in public cloud (AWS), micro services based large distributed system and is quality driven. Our stack consists of Scala, Play, Akka, MongoDB, PostgreSQL, Docker, Mesos, Marathon, Jenkins, Kafka, Spark, HDFS etc.

Our engineering culture can be defined as following:

Flexible minds: We need to do a lot with small teams, so it's important to use the right tools for the right job and be willing to change down the line if we find a more efficient solution. We also believe in "strong opinions, weakly held," being humble, and accepting and giving feedback.

Self-driven: Developers are given a large amount of autonomy in how they work, who they work with, when they work, and are responsible for a large part of driving project functionality and seeing things through to completion.

Quality-focused: Quality code helps a small team do more. Increasing communication through code readability and testing decreases the cost of maintenance to ensure we don't work weekends.

Entrepreneurial: Developers are given complete ownership over their projects from design to implementation, testing, deployment, and production maintenance. We are active participants in product design.

Communicative: We believe in teamwork and sharing the experience through design reviews, code reviews, and weekly technology presentations.
