Senior Mobile Engineer II
This role can be performed remotely from anywhere within Czechia.
As a Senior Mobile Engineer II on the Guides and Surveys team, you will play a pivotal role in empowering Fullstory customers by architecting the cross-platform libraries—spanning React Native, Flutter, and other environments—that allow showing content like NPS surveys or embedded banners inside of client’s application based on in-app user behavior. You will serve as a senior engineer with a high level of ownership and autonomy, designing the technical foundation for tools that guide, delight, and convert users directly within their mobile journey. To excel in this role, you must be a product-focused engineer with a customer-centric mindset who is obsessed with shipping value and solving complex "small screen" challenges. By building high-performance, reusable systems that bridge the gap between data and engagement, you will have a direct impact on the business success of our global mobile platform and the digital experiences of millions of users.
In a typical day, you might:
Collaborate with Design, PM, and Engineering teammates to plan, architect, and build business-critical mobile features in a tight feedback loop with our customers. Well-written communication is essential.
Ideate with our core team on how to best architect mobile support for customers using Guides and Surveys.
Anticipate and develop support for new mobile (React Native, Flutter, iOS and Android) platform-specific features
Drive improvements to engineering processes, tooling, and best practices, contributing to the overall efficiency and effectiveness of the engineering organization.
Mentor and coach junior and mid-level engineers, providing technical guidance, conducting code reviews, and fostering a culture of engineering excellence.
Here’s what we’re looking for:
7+ years of professional mobile engineering experience with a proven track record architecting and designing complex technical solutions independently across the entire mobile stack.
Deep cross-platform expertise in React Native and Flutter, including experience building custom bridges, packages, and reusable libraries that ensure seamless compatibility across different host environments.
Strong proficiency in native development (Swift/Objective-C and Kotlin/Java) and a solid understanding of "small screen" design patterns, allowing you to tackle low-level systems challenges and performance optimization regardless of the framework.
Product-focused mindset with high autonomy, possessing the ability to translate customer needs into technical roadmaps and wisely balance architectural depth with the need to ship value to the Guides and Surveys platform.
Exceptional technical communication and mentorship skills, with the ability to serve as a foundational lead for the Guides and Surveys team and provide constructive feedback to cross-functional partners on solution design.
Bachelor's degree in Computer Science or a related field.
