Senior React Native Engineer

We do this by connecting global fanbases to the ultimate fan item: game-used and signed shirts from the world's biggest athletes and brands around the world. We accelerate engagement, interaction, and revenue by enabling our customers to access pieces of sporting history, while raising funds for the causes that matter most to our partners. The best part?

We see ourselves as innovators, constantly looking for new ways to surprise and delight our audience.

About the team & our way of working
The Senior React Native Engineer will be part of the Technology department within a cross-functional product team. The role sits alongside backend and frontend engineers, collaborating closely on the mobile experience layer of the platform.

The position reports to the Frontend Chapter Lead and works in alignment with product and infrastructure stakeholders. As a senior profile, this role is expected to provide technical guidance, influence mobile best practices, and contribute to elevating the engineering standard within the team. Junior or mid-level developers may collaborate closely with this role for technical direction and code quality alignment.

MWS operates in cross-functional, highly collaborative engineering teams. Teams work closely across backend (.NET), frontend (Vue/Nuxt), mobile (React Native), and infrastructure (AWS, Kubernetes, edge computing).

We adopt the Shape Up product development methodology, structuring work into focused 8-week cycles. Each cycle consists of a 6-week build phase and a 2-week cool-down. Cross-functional teams work autonomously on "shaped" projects (fixed-time bets) to deliver working software. This promotes deep focus, clear objectives, and predictable delivery, minimizing scope creep.

Engineers are encouraged to take ownership, contribute to shaping, and actively participate in architectural discussions. Code reviews, shared standards, and collective problem-solving are core to the culture. The environment is informal yet performance-driven, with a strong emphasis on quality, scalability, and continuous improvement.
