We need a dedicated owner to turn these fragmented pieces into one reliable agentic development lifecycle. - We have an opportunity to connect sandboxes, CI, verification, and background agents into a cohesive system that compounds across every engineering team. - We want to ship 10× faster by building the frontier agent harness for real-time voice AI. Agents will place real calls, validate their work against Vapi-specific systems, and ship with confidence. What You’ll Do: - 30 Days: Map and instrument Vapi’s path from task to production, identify the largest constraints on agent effectiveness, and ship your first improvements to our sandbox environment, developer tooling, or validation infrastructure. - 60 Days: Launch the first production workflow in Vapi’s internal software factory. Give background agents the context, tools, sandbox, telemetry, and automated quality gates required to turn scoped tasks into review-ready PRs backed by real evidence. - 90 Days: Own and launch Vapi’s platform for autonomous, background engineering. Bring the ambition of Ramp Inspect https://builders.ramp.com/post/why-we-built-our-background-agent and Stripe Minions https://stripe.dev/blog/minions-stripes-one-shot-end-to-end-coding-agents to the technically novel and difficult frontier of real-time voice AI. Build a harness that lets agents place real calls, measure latency, conversation quality, inspect telemetry, and iterate to a verified result. Create the foundation that accelerates every engineer and puts Vapi on a credible path to shipping 10× faster. Who You Are: - You have built internal platforms, developer tooling, or infrastructure that materially changed how engineers build, test, and ship software. - You are a hands-on engineer with strong software fundamentals across distributed systems, platform architecture, API design, CI/CD, and monorepo or large-codebase workflows. - You have practical experience building agent harnesses and using coding agents such as Claude Code, Codex, Cursor, or open-source equivalents on real engineering work. - You know how to design secure agent interfaces, MCP integrations, and sandboxed runtimes where agents can call APIs, run CLI commands, and use general-purpose tools safely. - You have built or operated online and offline LLM evaluation systems and can reason clearly about accuracy, latency, reliability, and cost. - You are fluent in at least one of TypeScript, Python, or Go and comfortable working across containers, databases, queues, orchestration systems, and modern cloud infrastructure. - You stay current on frontier models and techniques such as prompt caching, context compression, retrieval, and multi-agent coordination, and you know when the newest tool is useful versus distracting. - You thrive in ambiguity, seek raw input, and turn fragmented experiments into simple systems that other engineers want to use. How We Work: - Build something worthy of love: Craft matters. We build products and experiences customers genuinely love, not just tolerate. - Commit and follow through: We finish what we start and build trust by being people others can count on. - Why not today? We value urgency and momentum. The fastest path to customer value usually wins. - Seek raw input: We go directly to customers, data, and teammates instead of relying on summaries or assumptions. - It’s our problem: We operate as one team. We share credit, own mistakes together, and support each other when things get hard. - Be direct and kind: We give feedback clearly, respectfully, and without delay. Why Vapi: - Generational impact: Build the human interface for every business - Ownership culture: 30% of us are previous founders - Kind team: The founders, Jordan and Nikhil, are Canadians - Tier-1 investors: YC, Kleiner Perkins, Bessemer, M12, Peak XV, and more What We Offer: - Real stake: We offer a competitive salary and equity ownership - Comprehensive health coverage: medical, dental, and vision plans - Team love: We love hanging out, and we do quarterly off-sites - Flexible time off: take what you need - More: catered meals, transportation, equipment, and a $10k annual L&D budget
