Description

At Bolna, we’re building tools that change the way teams leverage Voice AI. We’re looking for a Python Backend Engineer to build features and expose capabilities powering our real-time voice AI platform. This is an early, high-impact role where you’ll shape the foundation of our product and directly influence its reliability, scalability, and performance. Our team is composed of IIT alums having worked at Bain, Atlassian, Zomato and are backed by top investors. Responsibilities: Architect and deliver user-facing features for our Voice AI platform that are scalable, fast, and production-ready. Work hands-on with customers to deeply understand their needs and design AI agents that fit real-world hiring workflows. Convert abstract ideas into tested, deployable solutions with quick iteration cycles. Collaborate with our core engineering team to evolve and design low-latency streaming pipelines handling 10,000+ concurrent voice sessions with strict performance SLAs. Required Skills: You have 3 - 5+ years building high-throughput distributed systems and scalable backend systems in Python, ideally with FastAPI (or similar frameworks), and deploying with Docker/Kubernetes. Strong fluency with asyncio, event loops, and concurrency patterns (multithreading, multiprocessing). Hands-on experience with WebSockets, LLMs, or agent-based architectures. High ownership mindset - you prefer building over waiting, and clarity over perfection. Clear communicator, comfortable working cross-functionally and making pragmatic decisions. BONUS: Background in a similar role - especially within voice AI or conversational AI startups. Why Join Bolna? Backed by YC, we’re on a mission to build a generational company out of India. Rocketship trajectory: We’re profitable, growing at YC speed, and handling 1M+ minutes of real conversations every month - you will have a shotgun seat in seeing these numbers multiply Founding team seat: You’ll be among the first 10 members and help shape our culture, GTM playbooks, and the very DNA of our growth story. Hard problems, real ownership: We’re orchestrating thousands of real-time Voice AI conversations in parallel. You’ll own high-stakes problems that touch engineering, customers, and revenue at once. Learn like a founder: This is not a narrow role. You’ll juggle sales, branding, hiring, and execution - the closest thing to running your own startup, with the safety net of a fast-growing team. Benefits: Competitive package + meaningful ESOP for early ownership + Health Insurance
