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 through natural, intelligent, and fast conversational interfaces.

We're looking for a Software Development Engineer II to join us at the ground level. This is a high-ownership, high-velocity role for builders who want to move fast and go deep.

What You’ll Do

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

Must-Have Skills

• 2+ years of experience with Python, building scalable production systems
• Proven experience independently leading projects from design through deployment
• Strong foundation in system design, algorithms, and data structures
• Deep understanding of backend architecture—APIs, microservices, data flows
• Proven ability to debug and optimize complex systems
• High autonomy—can break down big problems, prioritize, and deliver without hand-holding
• Prior success in early-stage startup environments, especially during 0→1 phases

Nice-to-Have

• Exposure to Node.js and React.js (Preferred but not mandatory)
• 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
• High-trust environment focused on impact—not hours
• Flexible work style and a fast, flat, and collaborative culture
