About Nexa

Nexa is a new venture by the founders of HeyCoach—Pratik Kapasi and Aditya Kamat—on a mission to build the most intuitive voice-first AI platform. We’re rethinking how humans interact with machines using natural, intelligent, and fast conversational interfaces.

We're looking for a Tech Lead to join us at the ground level. This is a high-ownership, high-speed role for builders who want to move fast and go deep.

What You’ll Do

• Design, build, and scale backend and full-stack systems for our voice AI engine
• Work primarily with Python (core logic, pipelines, model integration), and support full-stack features using Node.js and React.js
• Lead projects end-to-end—from whiteboard to production deployment
• Optimize systems for performance, scale, and real-time processing
• Collaborate with founders, ML engineers, and designers to rapidly prototype and ship features
• Set engineering best practices, own code quality, and mentor junior team members as we grow
  
  

✅ Must-Have Skills

• 4+ years of experience in Python, building scalable production systems
• Has led projects independently, from design through deployment
• Excellent at executing fast without compromising quality
• Strong foundation in system design, data structures and algorithms
• Hands-on experience with Node.js and React.js in a production setup
• Deep understanding of backend architecture—APIs, microservices, data flows
• Proven success working in early-stage startups, especially during 0→1 scaling phases
• Ability to debug and optimize across the full stack
• High autonomy—can break down big problems, prioritize, and deliver without hand-holding
  
  

🚀 What We Value

• Speed > Perfection: We move fast, ship early, and iterate
• Ownership mindset: You act like a founder-even if you're not one
• Technical depth: You’ve built things from scratch and understand what’s under the hood
• Product intuition: You don’t just write code—you ask if it solves the user’s problem
• Startup muscle: You’re scrappy, resourceful, and don’t need layers of process
• Bias for action: You unblock yourself and others. You push code and push thinking
  
  

Humility and curiosity

: You challenge ideas, accept better ones, and never stop learning

💡 Nice-to-Have

• Experience with NLP, speech interfaces, or audio processing
• Familiarity with cloud platforms (GCP/AWS), CI/CD, Docker, Kubernetes
• Contributions to open-source or technical blogs
• Prior experience integrating ML models into production systems
  
  

Why Join Nexa?

• Work directly with founders on a product that pushes boundaries in voice AI
• Be part of the core team shaping product and tech from day one
• High-trust environment focused on output and impact, not hours
• Flexible work style and a flat, fast culture
