Senior iOS Software Engineer
Contentsquare is a global digital analytics company empowering the brands you interact with every day to build better online experiences for all. Since our founding in France in 2012, we have grown to be a truly global and distributed team – known as the CSquad – representing more than 70 nationalities across the world.
In 2022, we raised $600M in Series F funding, doubling our valuation to $5.6B and were recognised as a certified Great Place to Work in France, Germany, Israel, US and UK.
🚀 Our mission
At 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 Senior Software Engineers 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 stack
On 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 challenges
Our first challenge is to navigate through uncharted territories, native APIs and 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 & Mindset
If 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), or if you enjoy testing new 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 Senior Software Engineers 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 and providing meaningful comments during code reviews.
As a Senior Software Engineer, you will also be expected to tackle more transversal topics (across the whole R&D) ensuring a strong technical guidance and clear status communication. We also like our teams to be diverse, so mentoring more junior developers will definitely be an option as well.
Finally, to be successful, you will have to showcase a good amount of curiosity and creativity to solve the complex challenges we are facing (bonus point if finding 0 results on StackOverflow or Google doesn’t stop you) as well as being ready to challenge the product, features and projects in a pragmatic and mindful manner.
