What does Vaani do?

Vaani AI Research is advancing the field of Voice AI by developing next-generation, human-like conversational infrastructure and foundational speech model. We aim to shift ~35% of today's digital system interactions from GUI to Voice and we are committed to redefining the voice AI landscape with cutting-edge technology and research initiatives.

Role Description:

This is a full-time on-site role for a System Programmer specializing in Realtime Voice Systems (C/C++/Rust), based in HSR Layout, Bengaluru. The System Programmer will be responsible for real-time voice application development, optimizing algorithms and system performance, working with voice processing technologies, and collaborating closely with cross-functional teams to deliver scalable solutions. The role involves debugging, testing, and maintaining high-performance code while ensuring the seamless integration of AI-powered systems.

Professional And Technical Prowess:

Deep proficiency in modern C++ and/or Rust (17/20) and low-level system programming, with a focus on performance-critical application development.
Fundamental understanding of real-time systems, low-latency programming, and optimization techniques for voice systems.
Expertise in network programming (TCP/IP, UDP) and kernel-bypass technologies like Sockets Direct Protocol.
Strong command of multithreading, concurrency, and lock-free data structures to ensure maximum system throughput and efficiency.
Experience with high-scale data processing pipelines and Big Data frameworks that facilitate the integration of machine learning outputs for execution.

Proven performance. College and pedigree no bar.

We are a group of 11 individuals, each having their own special powers. We dream (with our eyes open) to build state-of-the-art Voice systems from India - and it often comes with challenges. You will have fewer resources, compute, data, time and you get it. The job of each of our teammates is to figure the shit out by owning it - and find innovative ways (often with newer approaches and architectures) to make it happen. Thus, you will need to be a fun person to work with who can work with the team.

We will listen, learn, be empathetic and help selflessly in our interactions with everyone and through business, we will better the lives of those less fortunate than ourselves, as well as help world move a little bit ahead in the right direction.
