About the Team

You join a distributed team across Europe and Asia, with shared time for collaborative activities such as planning, retros, stand-ups, and brainstorming sessions. Your teams will own the core architecture for our Cross-platform application for Mobile and Web, which serves millions of monthly active users.

About the role:

This is the role for you, if you’re excited to work on the things listed below:

• Architecture Technical Strategy – Define and evolve the architecture for our cross-platform app, ensuring it is scalable, performant, and maintainable. Drive technical direction and long-term strategy aligned with product goals.
• Cross-functional Collaboration – Partner with product, design, and engineering teams to shape solutions that deliver great user experiences while meeting engineering constraints.
• Hands-on Technical Leadership – Dive deep when needed: write reference implementations, lead architecture reviews, and support teams with technical guidance and mentorship.
• System Design Quality – Champion best practices in system design, modularity, code quality, and testing. Identify and address system-level issues before they impact product delivery.
• Coding – Prototyping and solving some of our most complex technical challenges.

The skills you will need to be successful in the above:

• Strong technical background in building and scaling high-impact B2C products, ideally with millions of users.
• Deep expertise in mobile or web architecture – whether iOS (Swift), cross-platform (WASM), or frontend (React), you have the hands-on skills to make decisions and prototype when needed.
• Proven experience architecting complex systems – you’ve made key design decisions that have stood the test of time and scale, ideally in a cross-platform or multi-client environment.
• Ability to influence and lead across teams – even without direct management, you help engineers make better decisions through mentorship, communication, and technical leadership.
• Bonus if you bring:
• Experience with real-time collaborative productivity products.
• Experience with local/offline-first experience and event-sourced systems
• Experience leading architectural initiatives across multiple teams or working closely with engineering leadership.
• Passion for architecture and innovation – you stay current with the latest technologies, architectures, and practices in mobile, web, and platform development.

Even if you don’t meet all the criteria listed above, we would still love to hear from you! GoodNotes places a lot of value on learning and development and will support your growth if needed.
