# Software Engineer - Company: [Bolna]() - Location: Bengaluru - Team: Engineering - Employment type: Full Time - Posted: July 23, 2026 ## Job description At Bolna, we’re building tools that change how businesses leverage voice AI. We’re looking for a **Software Engineer** to build reliable, scalable systems that power millions of production conversations across languages, industries, and telephony environments. This is a **high-impact, high-ownership** role where you’ll work on core platform problems across distributed systems, real-time communication, developer infrastructure, and customer-facing products. Our team includes IIT alumni with experience at Bain, Atlassian, Uber, Zomato, and LinkedIn, and is backed by leading investors. ## Responsibilities 1. **Build systems that operate at scale:** Design and build backend services that support high-volume, real-time voice AI conversations with strong reliability, performance, and fault tolerance. 2. **Own features end to end:** Take problems from product requirements and technical design through implementation, testing, deployment, monitoring, and iteration. 3. **Improve platform reliability:** Build systems that are observable, resilient, and easy to debug. Identify bottlenecks, reduce failure rates, and improve system availability. 4. **Work on real-time infrastructure:** Solve problems across telephony, streaming audio, webhooks, queues, scheduling, concurrency, and low-latency communication. 5. **Build for developers and customers:** Improve APIs, SDKs, integrations, dashboards, and internal tools that make the Bolna platform easier to use and operate. 6. **Raise the engineering bar:** Contribute to technical design reviews, code quality, testing standards, documentation, incident response, and engineering best practices. ## Required Skills 1. **Strong engineering fundamentals:** Solid understanding of data structures, algorithms, databases, networking, operating systems, and distributed systems. 2. **Backend development experience:** 2+ years of experience building and operating production backend systems using Python, Go, Java, Node.js, or a similar language. 3. **Production ownership:** Experience shipping software to production and owning its reliability, monitoring, and performance after release. 4. **Database experience:** Strong understanding of relational databases, data modelling, indexing, transactions, and query performance. 5. **API design:** Experience designing and building reliable REST, event-driven, or real-time APIs. 6. **Problem-solving mindset:** Ability to break down ambiguous problems, make sound technical trade-offs, and deliver pragmatic solutions. 7. **Bias toward shipping:** You value speed, but not at the cost of quality. You test, deploy, monitor, and improve what you build. ## Preferred Skills 1. **Voice AI orchestration:** Experience building real-time conversational systems that orchestrate ASR, LLM, and TTS models over streaming or WebSocket-based pipelines. 2. **Speech and AI provider integrations:** Experience integrating external ASR, LLM, and TTS providers and designing abstractions that make models and vendors interchangeable. 3. **Real-time media pipelines:** Familiarity with streaming audio, buffering, interruption handling, turn-taking, retries, timeouts, and fault-tolerant conversation flows. 4. **Bolna ecosystem familiarity:** Prior experience using, contributing to, or building on the open-source `bolna-ai/bolna` voice-agent orchestration framework is a strong advantage. ## Why Join **Backed to build big:** Bolna is backed by Y Combinator and leading investors, and we are on a mission to build a generational voice AI company from India. **Rocketship trajectory:** We are profitable, growing rapidly, and handling more than 4 million minutes of real conversations every week. Your work will reach production quickly and operate at meaningful scale. **Hard engineering problems:** You’ll work on distributed systems, real-time infrastructure, telephony, reliability, latency, and platform scale—not isolated features. **Real ownership:** You’ll own meaningful parts of the product and platform, from technical design through production performance. **Strong customer feedback loop:** You’ll see how your work affects real businesses and use production feedback to improve the platform. **Learn beyond code:** You’ll work closely with product, ML, infrastructure, and customer-facing teams, and gain visibility into how technical decisions influence product and business outcomes. ## Benefits Competitive compensation, meaningful ESOP ownership, health insurance. ## Apply [Apply on Bolna]() Canonical job page:
