Role Mission
We're hiring a senior developer/architect to lead the development and QA teams and manage the project itself across the next phase of a large-scale, high-traffic digital platform modernization: migrating a headless Next.js + CMS stack onto Vercel, in parallel with a personalization/experimentation build shipping on the current infrastructure. You'll direct both teams responsible for this engagement, own technical oversight across every workstream, run the project plan and tracking, and sit client-facing co-designing the architecture in real time with the client's engineering leadership and their UX/UI implementation partner.

Requirements

Key responsibilities; Lead both the development team and the QA team across the full engagement — assigning work, reviewing implementation, setting the technical and quality bar, and acting as the escalation point across all workstreams.; Own project management for the initiative: maintain the project plan and timeline, run the Linear-tracked exit-criteria checklist through weekly review, and report status and risk to stakeholders.; Direct QA and acceptance testing for the Payload-on-Vercel migration build (cold-start/connection-pool behavior, Jobs Queue rebuild, bulk-operation limits) — the build is executed by another party; this role owns sign-off, not the implementation itself.; Direct QA across the entire initiative — every workstream in the migration and personalization build passes through development and QA review before it's considered done.; Define and validate performance budgets for the new architecture (TTFB, LCP, INP, CLS, personalization latency, tentpole-load behavior), and test the Vercel build against them under simulated peak traffic.; Decide and stand up observability tooling — infrastructure monitoring, uptime checks, and application performance/error tracking — instrumented on Vercel from day one.; Own disaster-recovery design and testing for the new Vercel/Neon topology.; Support cost modeling — projecting Vercel usage cost at steady-state and traffic-spike volume against a proposed dollar ceiling.; Co-lead security and privacy validation of the new architecture — access management, secrets, application security, edge/runtime security, monitoring, and consent/privacy compliance (GDPR/CCPA) via OneTrust — alongside client stakeholders.; Partner with the client's UX/UI implementation team on caching correctness (cache-hit/miss behavior, cross-visitor isolation, invalidation) as part of the migration test suite.; Act as direct technical point of contact with client-side engineering and product leadership, translating architecture tradeoffs into terms non-technical stakeholders can act on.; Skills & experience; 7+ years of experience in full-stack development, software architecture, or similar roles, with hands-on experience in Vercel, Next.js/React , headless CMS, GraphQL, and Postgres (Neon is a plus).; Experience leading development and QA teams, setting technical standards, reviewing implementations, and owning acceptance criteria and deliverable quality.; Experience in technical project management, including planning, tracking, risk management, and stakeholder communication. Linear experience is a plus.; Knowledge of QA, testing, performance, observability, disaster recovery, security, and privacy, ideally with OneTrust and GDPR/CCPA knowledge.; Experience migrating or re-architecting high-traffic production systems, particularly in cloud/edge environments. Cloudflare Workers and AWS are a plus.; Knowledge of personalization, experimentation, CDP/identity systems, or Salesforce Marketing Cloud is a plus.; Experience working with clients, agencies, and external teams, with fluent English and strong communication skills across technical and non-technical stakeholders.; Ability to work effectively in ambiguous, fast-paced, and cross-functional environments, making technical decisions and translating architectural trade-offs into business needs.; Benefits; Work your way — Flexible schedule, hybrid work, and the opportunity to work up to 3 weeks a year from any SAMY office around the world.; Time that matters — Celebrate your birthday with a day off, plus company holidays on December 24th and 31st to recharge.; Grow with us — Global mobility opportunities, mentorship, parenthood support, and a transparent performance-driven compensation framework.
