Why We’re Hiring This Role:

- Vapi engineers are already building agent skills, workflows, and tools. 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

- **Founders**: Jordan Dearsley and Nikhil Gupta

## Core Business
- **Primary industry**: Voice AI Infrastructure / Developer Tools
- **Target customers**: B2B, primarily Large Enterprises (e.g., Amazon Ring, Intuit, New York Life) and a self-serve developer platform for SMBs.
- **Mission or purpose**: To provide the infrastructure and orchestration layer for companies to build and deploy voice agents that deliver high-quality outcomes at scale.

## Products & Services
- **[Vapi Platform]**: An API-first platform that provides the core infrastructure for building, testing, and deploying voice AI agents. It handles speech-to-text, AI orchestration, and text-to-speech, with sub-500ms latency. It supports two main primitives:
    - **Assistants**: Single-agent setups for specific tasks like customer support, lead qualification, and booking.
    - **Squads**: Multi-agent orchestration for complex workflows with context-preserving transfers (e.g., medical triage, e-commerce routing).
- **[Vapi CLI]**: A command-line tool that brings the full power of the Vapi platform to a developer's terminal for rapid iteration and deployment.

## Market Standing
- **Valuation**: ~$500 million (post-money, as of May 2026)
- **Key Metric**: Annual recurring revenue (ARR) is in the "healthy" eight figures. Total funding is $72 million.
- **Notable Investors/Partners**:

    - Won Amazon Ring, a high-profile enterprise customer, in late 2024.
    - Active job postings are growing (+20.8% quarterly).

## Competitive Advantages
- **Enterprise-Grade Infrastructure**: Offers sub-500ms latency, built-in AI guardrails, SOC 2, HIPAA, and PCI compliance, single sign-on (SSO), OAuth2, and role-based access control (RBAC).
- **Developer-First, Then Enterprise**: The platform was battle-tested at significant scale through its self-serve developer community before signing major enterprise clients, giving it a robustness that competitors lack.
- **Granular Control**: Provides enterprises with deep control over the behavior, reliability, and compliance of their AI agents, which was a key factor in winning Amazon Ring's business.
- **Scalability**: Proven to handle massive volume (billions of calls) with a 99.9% uptime SLA for enterprise clients.

## Strategic Focus
- **Hiring for Scale**: The company is actively expanding its engineering, infrastructure, and go-to-market teams to capitalize on its growth.
- **Deepening Enterprise Penetration**: Following the win with Amazon Ring, Vapi is focused on onboarding more large, complex enterprises.
- **Infrastructure over Application**: Vapi aims to differentiate by being the underlying orchestration and reliability layer for voice AI, rather than a pre-packaged application.

## Why Work Here
- **High-Impact, Fast-Growing**: Vapi is at the center of the booming voice AI space, processing billions of calls and serving iconic companies like Amazon. Employees have a direct impact on a platform that is reshaping customer service.
- **Engineering Culture**: The company is API-first and developer-centric, founded by engineers from the University of Waterloo and Y Combinator.
- **Remote/Hybrid Policy**: The company appears to have a hybrid model, with roles listed in New York City (NYC) and likely San Francisco, but also offers a degree of flexibility.
- **Notable Perks/Culture**: The company is still in a high-growth phase (around 100 employees), offering the opportunity to work on cutting-edge AI infrastructure with a strong focus on engineering excellence and deployment support. The team includes a "Forward Deployed" engineer role, indicating a culture of deep customer partnership.
