Forward-Deployed Engineer

Backend Developer • On-site • Full-time • 📍 Hybrid - London

Vercel is looking for a Forward-Deployed Engineer to join its Professional Services team. This is not a traditional consulting role: you embed directly with the most strategic enterprise customers to drive transformational outcomes across frontend modernization, platform migrations and AI adoption. You will lead complex Next.js migrations, architect high-performance applications and build production AI solutions hands-on within customer environments. The role reports to the Director of Professional Services and is remote-first with significant travel (25–40%) to customer sites.

Responsibilities

  • Lead complex frontend migrations, modernizing legacy React, Vue or other frameworks to Next.js, including Pages to App Router transitions and large-scale codebase transformations
  • Conduct technical assessments and code audits for performance bottlenecks, architectural anti-patterns and optimization opportunities, delivering actionable roadmaps
  • Architect and implement high-performance Next.js applications using App Router, Server Components, streaming, ISR, edge functions and advanced rendering strategies
  • Optimize Core Web Vitals and application performance using tools like Vercel Speed Insights
  • Build production AI solutions using Vercel's AI SDK and AI Cloud, including conversational interfaces, production agents, MCP servers and agentic workflows
  • Embed with strategic customers to ship production TypeScript code within their systems and constraints
  • Drive enablement and knowledge transfer through workshops, pair programming and documentation
  • Navigate complex enterprise environments and build relationships across engineering, product and executive teams
  • Participate in pre-sales activities: discovery calls, scoping sessions and proposal development
  • Contribute to service evolution by identifying repeatable patterns, building reusable components and sharing insights with Product and Engineering

Requirements

  • 5+ years of software engineering experience, with at least 2 years in a customer-facing technical role (consulting, solutions engineering, forward-deployed engineering or technical founder experience)
  • Expert-level TypeScript skills as your primary language, writing production TypeScript daily
  • Deep Next.js expertise: App Router, Server Components, SSR, SSG, ISR and edge functions in complex applications
  • Demonstrated experience leading frontend migrations of large codebases to Next.js in production environments
  • Mastery of React and its ecosystem, including advanced state management, performance optimization, streaming, suspense and concurrent features
  • Production experience with LLMs and AI applications, including prompt engineering, agent development and tool-use patterns (familiarity with Vercel's AI SDK strongly preferred)
  • High agency and comfort with ambiguity
  • Exceptional communication skills: technical discovery, executive presentations, mentoring and relationship building
  • Business acumen to translate technical capabilities into ROI and identify expansion opportunities
  • Willingness to travel 25–40% to customer sites

Nice to have

  • Led large-scale migrations from legacy setups (Create React App, Gatsby, custom webpack) to Next.js in enterprise environments
  • Expertise in performance optimization and Core Web Vitals (diagnosing and fixing LCP, CLS and INP issues at scale)
  • Experience with Model Context Protocol (MCP), building MCP servers or complex tool-use patterns in production AI applications
  • Led enterprise AI transformation initiatives with production agents automating manual processes
  • Experience with micro-frontends, module federation or multi-team frontend architectures
  • Contributions to Next.js, React or AI SDK open-source projects, or maintaining popular related libraries
  • Experience with enterprise deployment patterns: security reviews, compliance requirements, multi-region architectures
  • Background in financial services, healthcare, retail/e-commerce or media
  • Conference speaking or published thought leadership on frontend architecture, migrations or AI applications
