Role Name: Full-Stack Platform Engineer Location: Los Angeles, US (Onsite) Duration: 12+ Months Full-Stack Platform Engineer (Contentstack Launch + Next.js) — FocusFeatures and UAA/UPAH Scale About the role You will be the primary engineer developing, operating, and troubleshooting two high-visibilitycontent sites built on a shared stack: Next.js/React delivered via Contentstack Launch withSSR and CDN caching/revalidation. Editorial changes publish into time-based cache windowsrather than instantly. Backend/platform scope spans: title/asset ingestion from OVC with assets from CVP/MPXinto Contentstack (in a separate AWS account) for UAA/UPAH, plus AWS serverless featuresand mParticle integration for Focus Features, with DataDog planned and Cloudflare beingdecommissioned. Required years of experience 7+ years professional software engineering for large-scale web platforms.3+ years building and operating Next.js/React applications with SSR and CDNcaching/revalidation.2+ years hands-on with headless CMS and Contentstack Launch (content models,environments/builds, cache invalidation triggers).2+ years operating AWS serverless workloads (e.g., Lambda, API Gateway) and productionintegrations (e.g., mParticle).2+ years production monitoring/alerting and incident response (e.g., DataDog plannedadoption).Experience with media title/asset ingestion flows (OVC, CVP/MPX ? CMS) and coordinatingacross accounts/environments. Key responsibilities Frontend (Next.js/React + SSR)Own SSR routes/components, performance, accessibility/SEO; manage cache-controlheaders and confirm edge caching/revalidation behavior.CMS and Launch operations (Contentstack)Evolve content models; manage Launch environments/builds and automations that triggerpage-level cache invalidation after publish.Caching and freshnessTune time-based cache policies and revalidation for page types (e.g., titles, lists, search;typical windows around 5 minutes, configurable).Ingestion and data quality (UAA/UPAH)Maintain mappings/transforms from OVC/CVP/MPX into Contentstack; align data freshnesswith cache windows; coordinate with the separate AWS account.Serverless features and integrations (Focus Features)Operate and troubleshoot AWS serverless features (e.g., Insiders, Facebook Leadgen) andmaintain mParticle integration paths.Observability, reliability, and releasesImplement/maintain monitoring and alerting (DataDog planned), create runbooks, leadincident response across frontend/Launch, ingestion, and serverless paths.Own CI/CD via Contentstack Launch; coordinate release timing with cache revalidation andingestion cycles; support system simplification (e.g., Cloudflare decommission). Minimum qualifications Proficiency with Next.js/React SSR and CDN caching/revalidation at scale.Hands-on expertise with Contentstack Launch operations and page-level cache invalidationflows.Experience operating AWS serverless features and data integrations (including mParticle formembership features).Demonstrated ownership of ingestion pipelines for media metadata and assets into a CMS(OVC/CVP/MPX ? Contentstack).Solid monitoring/alerting, on-call participation, and incident response. Preferred qualifications Introducing or maturing DataDog dashboards/APM/alerts; driving platform simplification (e.g.,retiring secondary CDN components like Cloudflare).Strong collaboration with editorial teams on caching expectations and publishing workflows;tuning TTLs and revalidation behavior. Primary troubleshooting domains CDN cache headers/revalidation, stale content windows.Ingestion timing/field mapping issues across OVC/CVP/MPX into Contentstack.Serverless endpoints/integrations for Insiders/Leadgen and related data paths.
