What We Expect at SDE II Level
At this level, the candidate should be more than someone who can implement assigned tasks.
You should be able to:
- Take ownership of a feature from requirement → technical architecture design → implementation → testing → deployment.
- Make sound technical decisions independently.
- Design reusable and scalable systems.
- Diagnose complex issues involving software, hardware, and performance.
- Identify technical risks before they become development blockers.
- Review and improve other developers' code.
- Mentor junior developers.
- Communicate technical concepts clearly with both technical and non-technical stakeholders.
Why Join Us
- Work on challenging AR/VR/MR applications.
- Work with modern XR hardware and technologies.
- Solve complex problems involving Unity, real-time 3D, interaction, and hardware integration.
- Opportunity to take significant technical ownership.
- Work closely with multidisciplinary Product, 3D, UI/UX, Engineering, and QA teams.
