🚀 Our missionAt Contentsquare, all employees share one goal: to help brands create exceptional online experiences with our industry-leading digital experience analytics platform.In the mobile data collection team, we are on a mission to build the industry leading digital experience analytics SDK.With a stellar growth, billions of users, a complex business environment and the need for us to have a very high level of quality, performance and privacy, you’ll find an engaging, rewarding and supportive work environment at Contentsquare.We are looking for developers who understand that development is a team effort, who are proud of a job well done and know how to implement simple and efficient solutions to solve challenging and unique problems.
💻 Our stackOn the data collection side, our SDK works on native iOS applications (implemented in Swift) and native Android applications (SDK is in Java - converted to Kotlin over time -, Unit Tests and Sample App in Kotlin). We also support various multi-platform frameworks (React Native, Flutter, Capacitor/Ionic, Cordova) with specific bridges.The Tag (implemented in Typescript) that collects data on websites (both desktop and web mobile) is implemented and maintained by the Web Team.Our APIs are mostly designed with our specific constraints in mind. For example, the most data intensive ones use Protocol Buffers.Our backend uses a combination of technologies such as Kafka, Spark, Flink, Akka, ClickHouse and languages such as Scala, Golang, Python, C++.Our monitoring and deployment are handled through Kibana, Grafana, Terraform, Datadog and finally, everything is hosted on AWS and Azure.Our frontend is a micro-frontend SPA developed mainly in Angular/Vue.js and Node.js.
🧠 Our challengesOur first challenge is to navigate through uncharted territories, native APIs, cross-platform wrappers and bridges as well as poorly documented features to make sure we collect all the relevant data we need to compute our insights.In addition we obviously must ensure a very high level of performance (as well as the least impact on user experience), stability and be very mindful about data and CPU consumption.Our rapid growth requires a strong focus on software architecture, code sharing and automation to sustain our delivery capacity while increasing our teams' size.Finally, we are not a tracking company, so collecting PII (Personal Identifiable Information) is an absolute no-go for us and we take it very seriously!
🤗 Skills & MindsetIf you have already worked on any kind of software SDK your experience will be of great interest to us.In the same way, if you have notable experience in high performance code, automated non-regression and performance testing, software bridges (between technologies, native and non-native), and if you love working “between the lines” by bridging native and cross-platform technologies or frameworks such as Flutter/Dart, Swift UI, Compose, React Native/Typescript, we would love to hear from you.As a team we are really involved in producing a high quality SDK. We expect our developers to know how to unit test their code, to write easy to read & maintain code and documentation as well as being comfortable doing pair programming with their team members.
