We are seeking a talented Senior Graphics Engineer to join our Rendering team and help us push the boundaries of high-performance, GPU-accelerated ink rendering.

If you have deep experience in GPU programming (ideally with Metal and/or OpenGL/WebGL) and love working on technically challenging projects that have a big impact on millions of users, we’d love to hear from you.

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

• Contribute substantially to our ink rendering system, focusing on rendering smooth, high-fidelity 2D vector-quality pen strokes using the GPU.
• Research and implement state-of-the-art rendering algorithms for digital ink and vector graphics.
• Optimize GPU pipelines for performance and memory efficiency across platforms.
• Collaborate closely with product and technical leaders on design, planning, and prioritization.
• Work hand-in-hand with other senior engineers in the Rendering team to improve rendering quality and speed.
• Share your expertise with the team and help elevate our rendering capabilities.

Required Skills:

• Significant experience with GPU programming, ideally using Metal and/or OpenGL/WebGL.
• Proven experience building or optimizing 2D vector graphics renderers on the GPU.
• Proficiency in at least one systems programming language such as C, C++, Rust, or Swift.
• Strong grasp of common algorithms and their performance characteristics.
• Several years of experience working on deep technical problems in rendering or graphics.
• Maker at heart with a track record of delivering high-quality, performant code in small teams.

Desired Skills:

• Experience with real-time rendering of ink or vector graphics at high resolution and low latency.
• Familiarity with GPU performance profiling and debugging tools.
• Experience implementing antialiasing, curve tessellation, or stroke reconstruction algorithms.
• Strong knowledge of shader programming and GPU compute pipelines.
• Experience optimizing rendering for multiple platforms (desktop, mobile, or web).

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.

The interview process:

• Introductory call with a member of the Talent Team. They want to hear more about your background, what you are looking for, and why you’d like to join Goodnotes
• 1 hour live coding interview with one of our engineers, focusing on data structure and algo style tasks
• 90 minute technical assessment featuring a rendering/object manipulation exercise and technical discussion
• 30 minute conversation around AI Literacy 
• 1 hour behavioural interview around the Goodnotes company values 

What’s in it for you:

• Meaningful equity in a profitable tech-startup
• Budget for things like noise-cancelling headphones, setting up your home office, personal development, professional training, and health & wellness
• Sponsored visits to our international office locations every 2 years
• Company-wide annual offsite
• Flexible working hours and location
• Medical insurance for you and your dependents
