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
