Company descriptionSWAB Technologies Private Limited is a Pune-based technology company. We are building an autonomous AI agent that takes voice commands and carries out real business work on its own, such as making calls and running ads. Role descriptionWe need an experienced AI engineer. This is not a role for freshers or for someone learning on the job. You will build this agent from the ground up. The founder defines what it must do. You decide how to build it, you build it end to end, and you own it for the long term.
• Build an autonomous AI agent that understands voice commands and takes action on its own
• Design and build MCP servers and tool integrations so the agent can operate real business tools
• Enable the agent to act: place and handle phone calls, create and run ad campaigns, and carry out other everyday business tasks
• Build realtime voice pipelines (speech-to-text, LLM, text-to-speech) with low latency, supporting Indian accents and languages
• Build the agent core: planning, tool calling, background task execution, retries, and memory
• Add guardrails so the agent asks for confirmation before irreversible actions such as spending ad budget, payments, or calls, and defend against prompt injection
• Build evaluations, monitoring, and cost and latency controls, so quality is measured and not assumed
• Turn the founder's requirements into working software without needing detailed specifications
• Own the system long term: architecture, reliability, security, and documentation Qualifications




• Experienced engineer required: significant hands-on experience building and shipping production software, including at least one LLM-based agent or voice product used by real users
• Able to build alone, end to end: backend, APIs, integrations, and deployment, without a large team or detailed specs
• Experience with tool calling, structured outputs, asynchronous jobs, and MCP or similar tool-integration protocols
• Strong in Python or Node.js/TypeScript
• Experience with realtime voice or telephony, or a working project that shows you can learn it quickly
• Understands security for connected business accounts: OAuth, token storage, and least-privilege access
• Based in Pune, or ready to relocate to Pune for this on-site role
• Can show a live product, repository, or demo you built and explain every major decision Nice to have:
• Experience with advertising platform APIs such as Meta or Google Ads
• Telephony or SIP integration experience
• Indian-language speech recognition or text-to-speech
• Early-stage startup experience as one of the first engineers What we value:
• Ownership: treats the product as theirs, not as a ticket queue
• Self-driven: takes a explicit goal and delivers without being managed step by step
• Long-term commitment: this is a multi-year build, and we want someone who plans to stay
• Direct and honest: tells the founder when an idea will not work, with reasons
• Pragmatic: ships a working version, then improves it with real usage
