- Experience with NLP, speech interfaces, or audio processing
- Familiarity with cloud platforms (GCP/AWS), CI/CD, Docker, Kubernetes
- Contributions to open-source projects or technical writing
- Prior experience integrating ML models into production systems
What We Value
- Speed > Perfection: We ship early and iterate fast
- Ownership mindset: You think and act like a founder
- Technical depth: You’ve built things from scratch and understand how they work
- Product intuition: You care about solving user problems, not just writing code
- Startup muscle: You’re scrappy, resourceful, and thrive without process overhead
- Bias for action: You unblock yourself and others—fast
- Humility and curiosity: You challenge ideas, accept better ones, and never stop learning
Why Join Nexa?
- Work directly with the founders on groundbreaking voice AI products
- Be part of the core team shaping the product and technology from day one
