• The work you do will be core to how individuals, classrooms, and organisations collaborate in Goodnotes, and it is also a key foundation for our B2B business
• We value a product-minded engineering culture, thoughtful technical design, and a strong focus on user experience and reliability
• We are hiring for an iOS Tech Lead for Real‑Time Collaboration

• You are expected to drive and coordinate the overall technical design so that all parts of the system come together into a coherent, best‑in‑class user experience
• This is the role for you if you're excited to work on the things listed below:
• Design and build real‑time collaboration features on iOS and iPadOS that feel seamless for tens of millions of users
• Push collaboration latency towards sub‑second experiences, while ensuring the system scales reliably to tens of millions of users
• Own complex client‑side systems end‑to‑end, from technical design and prototyping to shipping and iteration
• Evolve offline‑first sync flows so that collaboration remains robust even with poor connectivity
• Collaborate closely with backend and other client teams (Web, Windows, Mac, Android) on APIs, data models, and performance
• Raise the quality bar for user experience, performance, and reliability through thoughtful engineering practices, instrumentation, and experimentation
• Define and drive the technical roadmap for real‑time collaboration in partnership with product and design
• Lead the design of complex client architectures, including state management and real‑time data flows
• Drive end‑to‑end solution design across client and backend owners, ensuring we make the right trade‑offs for user experience, latency, and reliability
• Break down ambiguous, cross‑team problems into clear technical plans and milestones
• Coordinate execution across multiple engineers and squads, proactively unblocking others
• Give clear technical direction and feedback through design reviews, code reviews, and mentoring
• Champion best practices for performance, reliability, and observability on the client

• An introductory call with someone from our talent acquisition team. They want to hear more about your background, what you are looking for, and why you'd like to join Goodnotes
• A short online coding skills test
• A live coding / pairing session with one of our iOS engineers focused on data structures, algorithms, and practical iOS problems
• A technical interview (remote or onsite in one of our locations: London, Singapore, Hong Kong) focused on system design, iOS architecture, and asynchronous programming
