🧑‍💻 The Role

Step into a pivotal role where your expertise and leadership drive technical innovation and excellence.

As a Staff Engineer in our Mobile Platform team, you’ll lead the evolution of our mobile technology stack — with a strong focus on cross-platform mobile technologies like React Native and Flutter. This is not a native iOS or Android role — we’re looking for someone with a deep understanding of mobile architecture and app development across platforms.

Be a technical authority: Set high standards when it comes to Mobile development and lead by example.

Mentor and guide: Empower junior engineers and share your knowledge to foster their growth.

Champion best practices: Promote TDD, clean code, and robust architectural practices.

Collaborate effectively: Work across teams to create cohesive and scalable solutions.

🚀 What You'll Do

Provide Mobile expertise: Be the go to person when it comes to challenges related with Mobile App development.

Lead the technical direction of our mobile platform with a focus on cross-platform frameworks such as React Native and Flutter.

Collaborate with native engineers, but act as the go-to expert for modern cross-platform mobile technologies.

Drive technical discussions: Lead conversations about technical decisions, identify trade-offs, and guide the technical direction within your team.

Deliver quality solutions: Balance rapid delivery with maintainability to ensure the platform remains scalable and robust.

Hands-on development: Work closely with your team on complex problems, setting the standard for technical excellence.

🤝 How We Work Together

We're a team that values empowerment, collaboration, and ownership. You'll be expected to make decisions based on data, fostering open discussions and adapting to new information.

Leadership by example: Hold yourself and others accountable for delivering high-quality work.

Mentorship and knowledge sharing: Empower your team by providing guidance and fostering a collaborative environment.

Focus on developer experience: Champion simplicity, clean code, and a streamlined workflow for all engineers.
