Delivery Pipeline Caching Technical Debt Production Code Front End Software Development

Job description

You will work alongside a named Vercel Forward-Deployed Engineer who provides technical architecture and delivery assurance. You and the Sophus team will execute the assessment, migration, engineering, testing, CI/CD, deployment, and stabilization work.

This is not an advisory-only or front-end UI role. You must be comfortable entering an ambiguous legacy environment, defining an incremental migration path, writing production code, and owning delivery outcomes.

Responsibilities

? Assess legacy Ruby/Rails applications, AWS architecture, dependencies, APIs, data flows, infrastructure, deployment pipelines, and technical debt.

? Translate the assessment into an incremental migration strategy with defined workstreams, risks, acceptance criteria, coexistence patterns, cutover plans, and rollback procedures.

? Modernize legacy front ends and monolithic applications to React, TypeScript, Next.js, and Vercel.

? Build production applications using Next.js App Router, React Server Components, SSR, SSG, ISR, streaming, caching, and personalization.

? Preserve necessary Ruby/Rails and AWS services during staged migration while progressively moving appropriate workloads to Vercel.

Requirements

? 6+ years of professional software-engineering experience.

? At least 2 years in a customer-facing technical role such as consulting, professional services, solutions architecture, or forward-deployed engineering.

? Expert-level TypeScript and strong React engineering experience.

? Deep, recent, production-level Next.js experience.

? Proven ownership of at least one substantial legacy-application or large-codebase migration.

? Strong understanding of incremental modernization rather than only “big-bang” rewrites.

Strongly preferred

? Direct production experience deploying applications on Vercel.

? Ruby/Rails-to-Next.js modernization experience.

? Migration from Pages Router to App Router.

? Vercel AI SDK, AI Gateway, eve, Fluid Compute, Workflows, Sandbox, and Observability.

? Experience with high-volume retail, e-commerce, media, healthcare, or financial-services applications.

? Enterprise security, compliance, identity, and multi-region deployment experience.

? AI-assisted migration or code-transformation automation experience.
