About the role:

We are looking for a Forward-Deployed Engineer to join our Professional Services team. This is not a traditional consulting role—you will embed directly with our most strategic enterprise customers to drive transformational outcomes across frontend modernization, platform migrations, and AI adoption.

In this role, you will lead complex Next.js migrations, architect high-performance applications, and build production AI solutions—all within customer environments. You'll work hands-on-keyboard alongside customer teams, whether you're migrating a legacy React application to App Router, conducting a deep-dive code audit, or deploying production agents using Vercel's AI SDK. You will be equally comfortable leading a technical discovery session with engineering leadership as you are refactoring a complex rendering strategy or optimizing an agentic workflow.

Our Forward-Deployed Engineers operate with high agency and autonomy. You'll navigate ambiguous enterprise environments, assess technical debt, design migration strategies, and deliver measurable business value—all while building long-term relationships that expand our partnership with each customer.

You will report to the Director of Professional Services and will be remote-first with significant travel (25-40%) to customer sites for embedded engagements.

What you will do:

1. Lead complex frontend migrations—modernizing legacy React, Vue, or other frameworks to Next.js, including Pages to App Router transitions, incremental adoption strategies, and large-scale codebase transformations.
2. Conduct technical assessments and code audits, analyzing customer codebases for performance bottlenecks, architectural anti-patterns, and optimization opportunities—delivering actionable roadmaps that drive measurable improvements.
3. Architect and implement high-performance Next.js applications, leveraging App Router, Server Components, streaming, ISR, edge functions, and advanced rendering strategies to meet enterprise scale and performance requirements.
4. Optimize Core Web Vitals and application performance, using tools like Vercel Speed Insights to diagnose issues and implement fixes that improve SEO, conversion rates, and user experience.
5. Build production AI solutions using Vercel's AI SDK and AI Cloud—including conversational interfaces, production agents, MCP servers, and agentic workflows that transform customer operations.
6. Embed with strategic customers to build production applications—working within their systems, understanding their constraints, and shipping TypeScript code that goes live.
7. Drive enablement and knowledge transfer through workshops, pair programming, and documentation—ensuring customer teams can extend and maintain solutions independently.
8. Navigate complex enterprise environments by building relationships with stakeholders across engineering, product, and executive teams—translating technical capabilities into business outcomes.
9. Participate in pre-sales activities by providing technical expertise during discovery calls, scoping sessions, and proposal development for migrations, audits, and AI transformation engagements.
10. Contribute to our service evolution by identifying repeatable patterns, building reusable components, and sharing implementation insights back to Product and Engineering teams.

About you:

• 5+ years of experience in software engineering 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—this is your primary language. You write production TypeScript daily and have strong opinions on type safety, patterns, and tooling.
• Deep expertise in Next.js, with a proven track record of architecting and delivering complex applications using App Router, Server Components, server-side rendering (SSR), static generation (SSG), incremental static regeneration (ISR), and edge functions.
• Demonstrated experience leading frontend migrations—you've modernized legacy applications to Next.js, navigated incremental adoption strategies, and understand the challenges of migrating large codebases in production environments.
• Mastery of React and its ecosystem, including advanced state management, performance optimization, and modern patterns like 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 is strongly preferred.
• High agency with comfort in ambiguity—you thrive when given a problem to solve rather than a task to complete, and you can navigate complex organizations to drive outcomes.
• Exceptional communication skills with the ability to conduct technical discovery, present to executives, mentor engineers, and build lasting customer relationships—all with a low-ego, collaborative approach.
• Business acumen to understand customer objectives, translate technical capabilities into ROI, and identify expansion opportunities throughout engagement lifecycles.
• Willingness to travel 25-40% to customer sites for embedded work and relationship building.

Bonus if you:

• Have led large-scale migrations from legacy frameworks (Create React App, Gatsby, custom webpack setups) to Next.js in enterprise environments.
• Have expertise in performance optimization and Core Web Vitals, with experience diagnosing and fixing LCP, CLS, and INP issues at scale.
• Have experience with Model Context Protocol (MCP), building MCP servers, or implementing complex tool-use patterns in production AI applications.
• Have led enterprise AI transformation initiatives, including building production agents that automated manual processes or replaced legacy systems.
• Have worked with micro-frontends, module federation, or multi-team frontend architectures.
• Have contributed to the Next.js, React, or AI SDK open-source projects, or maintain popular related libraries.
• Have experience with enterprise deployment patterns including security reviews, compliance requirements, and multi-region architectures.
• Have a background in financial services, healthcare, retail/e-commerce, or media—industries with complex frontend ecosystems and growing AI adoption.
• Have spoken at conferences or published thought leadership on frontend architecture, migrations, or AI applications.

Benefits:

• Great compensation package and stock options.
• Inclusive Healthcare Package.
• Learn and Grow - we provide mentorship and send you to events that help you build your network and skills.
• Flexible Time Off - Flexible vacation policy with a recommended 4-weeks per year, and paid holidays.
• Remote Friendly - Work with teammates from different time zones across the globe.
• We will provide you the gear you need to do your role, and a WFH budget for you to outfit your space as needed.

The Role

PhysicsX is building a new category of engineering software — one where physics AI models don't just augment existing workflows, but fundamentally redefine what's possible in design and operations. Our Product team is expanding a portfolio of Engineering Applications that bring this capability directly to the engineers, scientists, and operators who need it most. If you're excited by the challenge of turning cutting-edge AI and simulation research into tools that change how the world's most complex engineering problems get solved, this is the team to do it with.

You'll join the Forward Deployed Applications team, a group that sits at the intersection of product development and customer delivery. Your primary mission is to work closely with customers on real engineering problems — and to turn what you learn into generalised, reusable product capabilities that raise the ceiling for every PhysicsX user. This isn't a traditional customer-facing role or a pure product role: it's the feedback loop that keeps our product grounded in genuine engineering value. You'll work alongside simulation engineers, data scientists, ML engineers, and backend developers, with significant autonomy in how you approach problems, and a direct line of influence over the direction of our growing application suite.

What you will do

• You'll spend meaningful time in conversations — with users unpacking real engineering workflows, with Delivery teams translating those needs into concrete requirements, and with the Product team debating which patterns are worth generalising. Expect to be a connector as much as a builder, and to develop a strong instinct for which customer insights have product-wide implications.
• You'll be expected to bring both rigour and initiative: writing clean, well-considered code, contributing to architecture decisions, and pushing back constructively when a bespoke solution risks diverging from the product vision. This team operates with a high degree of autonomy, and the expectation is that you use it thoughtfully.
• On any given day you might be designing a 3D visualisation that makes a fluid dynamics simulation instantly legible to a non-specialist, building a React interface that surfaces AI model outputs in a live operational context, or refactoring a one-off delivery prototype into something the whole platform can build on. The problems are genuinely novel, and the solutions you build here will define what engineering software looks like next.
• Contribute to a positive team culture through active participation, clear communication of progress and blockers, constructive code reviews, mentoring of junior engineers, and effective cross-functional collaboration with technical and non-technical stakeholders.
• Demonstrate a strong commitment to continuous development by seeking feedback, staying current with technology trends, sharing knowledge through guilds and documentation, and building expertise across multiple technical areas.
• Take initiative in breaking down complex problems, evaluating trade-offs, documenting technical decisions, and strategically addressing technical debt while balancing short-term delivery with long-term vision and business context.
• Write clean, maintainable code following established standards, implement comprehensive testing strategies across the test pyramid, apply secure coding practices and stay current with security threats, and build and maintain CI/CD pipelines and deployment processes with confidence.
• Gather requirements and collaborate with stakeholders to define scope, design systems and interfaces that balance functional and non-functional requirements, document technical decisions clearly, and identify and resolve performance bottlenecks through profiling and optimisation.
• Travel to customer sites in North America, Europe, Asia, Oceania, for an average of 3-4 weeks per quarter, where you'll collaborate closely with customers to build solutions on-site

What you bring to the table

• Effectively leverage HTTP frameworks and concurrency primitives, contribute to service interface design using patterns such as Protobuf and OpenAPI, develop composable client libraries with code-generation tooling, and ensure service availability through throttling, rate-limiting, and standard resilience techniques.
• Write clear and effective SQL with an understanding of database implementation trade-offs, leverage caching, memoisation, and messaging systems such as AMQP or NATS, and understand service discovery, schema drift mitigation, and the principles of 12-factor apps.
• Create API tests using mock services, contribute to service documentation, understand authentication flows and middleware patterns, and contrast architectural approaches such as REST, RPC, gRPC, and GraphQL to make informed design decisions.
• Build responsive web applications using modern frameworks such as React, Vue, or Angular, effectively translate graphic designs to web interfaces with semantic HTML, and develop reusable UI components that maintain design system consistency with a strong understanding of UX practices.
• Write clean type annotations and leverage generics to add type safety across API responses and external data, manage client-server state synchronisation with optimistic updates, and effectively use frontend build tools and bundlers such as Webpack, Vite, or Rollup.
• Understand the browser rendering model and JavaScript execution to identify and resolve performance bottlenecks, leverage HTTP methods, caching headers, CORS, and status codes effectively, and implement security mitigations for CSRF, XSS, and authentication using cookies and local storage.

Ideally

• Confidence working across the full stack — you're at home reasoning about frontend architecture in React and TypeScript as well as backend design in Python, and you understand the tradeoffs in both well enough to make and defend pragmatic decisions.
• Experience building on top of large, established codebases — you know how to move deliberately, contribute incrementally, and improve things without breaking them.
• A track record of delivering in customer-facing or time-pressured environments, with the judgement to know when to ship something fit for purpose now and when to push back in the interest of a more durable solution.
• The instinct to treat customer engagements as a source of product insight — you naturally ask why a workflow exists, not just how to support it, and you channel that curiosity into constructive, well-reasoned feedback to product teams.
• Familiarity with 2D and 3D data visualisation and the ability to make complex simulation or model outputs legible and useful to non-specialist users.
• An agile, collaborative working style — you engage seriously with code review, testing, and CI/CD, and you're as invested in the quality of your team's output as your own
