Vercel is hiring a Senior Software Engineer to join the AI Gateway team, responsible for developing and enhancing a unified API platform that provides access to hundreds of AI models from multiple providers (OpenAI, Anthropic, Google, and others). The role focuses on building reliable, low-latency systems that handle rate limiting, intelligent failovers, and seamless integrations, enabling developers to ship AI-powered applications without managing provider-specific complexities.
Key responsibilities include designing and implementing core platform features such as unified API endpoints, rate limit management, and intelligent failover mechanisms to maximize uptime and reliability. You'll write clean, efficient, well-documented code with thorough testing to ensure low-latency responses and stability for high-volume AI inference requests. The role involves close collaboration with cross-functional teams including product managers, AI researchers, and infrastructure engineers to integrate new AI providers and models while addressing scalability and performance challenges.
You'll also engage with the open-source community, contribute to Vercel's AI SDK and related projects, and gather user feedback and analytics to drive innovations in AI Gateway features such as enhanced billing unification, provider-agnostic authentication, and usage analytics.
Required qualifications include 5+ years of relevant software engineering experience, strong proficiency in JavaScript/TypeScript with backend development expertise, and experience with APIs and cloud infrastructure. You should have hands-on experience with AI/ML integrations, API gateways, distributed systems, or high-throughput services (rate limiting, caching, failovers). Open-source contribution experience and excellent communication skills are essential.
Vercel is the agentic infrastructure company behind Next.js, v0, and AI SDK, trusted by companies like OpenAI, PayPal, Ramp, and Supreme. The company is focused on enabling the next generation of AI-powered products built and operated by agents.
