About the Client

A production company that blends traditional marketing with content marketing to create engaging, audience-centric campaigns. Rather than simply “talking at” people, the agency focuses on producing creative content—such as video and other media—that connects with audiences by “talking with them,” fostering stronger engagement and impact.

About the Role

We’re looking for a senior full stack engineer to lead development on modern, high-traffic Next.js applications. You’ll own end to end delivery across product features, integrations, performance, and reliability. The role is fully remote and highly collaborative with product/design and stakeholders.

• Own full feature lifecycles: design, implement, test, ship, and iterate in a Next.js App Router codebase.

• Build and maintain robust server-side modules and integrations:

  • Payments (Stripe), auth (Clerk), content (Storyblok), email (Mailjet).

  • External Domain APIs including data backfills, sync, and webhook flows.

  • Background jobs/queues (QStash), secure admin endpoints, and operational tooling.

• Model and evolve data with Prisma; write efficient queries and safe migrations.

• Design and implement intuitive, scalable, and reusable content models within modern headless CMS platforms (e.g., Storyblok, Payload, Contentful, Sanity, or similar) which balances editor usability with technical flexibility.

• Improve performance, accessibility, SEO metadata, and SSR/ISR behavior.

• Perform QA and testing for websites, landing pages, and emails.

• Strengthen reliability: logging, error handling, idempotency, retries, rate limit strategies.

• Maintain a clean, modular architecture; refactor shared layouts/utilities to reduce duplication.

• Create scripts for data backfills and maintenance; document operational runbooks.

• Review code, mentor peers, and champion best practices for DX, testing, and security.

• Collaborate closely with design to deliver polished UI/UX and smooth interactions/scroll experiences.

• Develop and implement marketing assets for platforms including SFMC, Mailchimp, and Campaign Monitor.
