FrontendSeniorRemoteRemote, US (Mon, Tue and Fri in office if within commuting distance of SF or NYC)

Design Engineer, AI Gateway

You own product design and frontend implementation for Vercel's AI Gateway, which connects apps and agents to hundreds of AI models with one API key. You design and ship the journey of choosing a model, making a first request, diagnosing a failed one, and handling routing, budgets, credentials and security controls across the website, dashboard, CLI and API responses. There is no required path into the role; what counts is work you identified, built and shipped yourself. Base pay is $208,000 to $312,000 in San Francisco.

You set the technical strategy and roadmap for your domain and lead legacy overhauls across several teams, which is why the posting asks for ten-plus years; base pay is $223,000 to $278,000 in San Francisco with equity on top.

You are the first engineer for the growth systems that Replit's marketing, sales and partnerships teams run on. The work builds shared foundations for acquisition measurement and attribution across web and mobile, a deep-link standard, referrals and promotions, and audience pipelines, then adds agentic systems on top that watch performance, diagnose problems and run approved experiments. The posting asks for four-plus years of backend experience plus SQL and data warehouse work; base pay is $220,000 to $320,000 with equity on top.

BackendPrincipalHybrid8yr+Foster City, CA, US (3 days in office)

Principal Software Engineer, Money Infrastructure

The money Replit earns, the money builders on the platform earn, and the money agents spend on someone's behalf all pass through one team. A single principal IC designs and runs the flow that stretches from pricing and subscriptions to usage-based billing, marketplace payouts, and in-app payments. Leaving behind abstractions flexible enough that a new plan does not mean rewriting the payment code is part of the brief.
