The Role
As a Software Engineer at Nex, you will contribute to building the technical foundations that power our platform’s most demanding capabilities. In the Framework Engineering track, you will own the design and development of our cross‑platform software framework for detection, sensing, haptics, and ML inference. You will build real‑time systems, hardware abstraction layers, and developer APIs that enable multimodal interaction on Nex Playground.
The Mindset
You are drawn to solving complex technical challenges at the intersection of research and production engineering. You care deeply about building systems that are reliable, performant, and maintainable. You thrive in environments where technical depth matters, where your expertise in ML systems, distributed computing, or real‑time software directly shapes what the platform can do.
What You’ll Do
- Design and develop a robust, performant, cross‑platform framework for sensing, detection, haptics, and ML inference
- Build efficient runtime execution systems and hardware abstraction layers
- Develop developer APIs that make complex sensing and inference accessible
- Optimize for real‑time performance on multimodal data streams
- Work on camera, microphone, and haptics integration
- Implement code that runs reliably across different platforms and hardware configurations
- Improve framework stability, performance, and developer experience
- Write clean, well‑tested code that maintains high engineering standards
- Participate in code reviews and help raise the engineering bar across the team
- Contribute to shared tools, infrastructure, and cross‑role projects (20% time)
- Work with the dual‑leadership model (Engineering Manager and Tech Lead) to understand priorities and technical direction
- Document systems and decisions to support team knowledge sharing
Must Have
- 3+ years of professional software engineering experience in building real‑time software frameworks, cross‑platform systems, or performance‑critical applications
- Proficiency in C++/C#, with additional experience in at least one other systems language (C++, C#, Java, Rust, or Go)
- Experience with cross‑platform development
- Proven track record with performance optimization, real‑time systems, or hardware abstraction layers
- Experience building developer APIs or software frameworks used by other engineers
Nice to Have
- Experience building real‑time systems or low‑latency software
- Familiarity with computer vision, signal processing, or embedded systems
- Experience with cross‑platform development or hardware abstraction
- Knowledge of performance optimization and profiling
- Experience with sensing technologies (cameras, microphones, or similar)
- Familiarity with CI/CD pipelines and automated testing
- Experience working in small, high‑performance technical teams
- Background in startups, high‑growth environments, or consumer product companies
- Passion for pushing technical boundaries and deep problem‑solving
We Offer
- Competitive compensation package
- Flexible working hours and vacation policy
- Product‑driven culture that treasures talents and individual growth
- Front‑row seat and hands‑on experience with cutting‑edge technologies in the evolving gaming field
