Senior Full - Stack Engineer

Job Summary


About the role


Responsibilities

• Build marketing sites, customer portals and CRMs in Next.js and TypeScript, from the data model to production.
• Model content in a headless CMS and Postgres so that editors can publish, preview and schedule without a developer.
• Keep every release inside its budgets - Core Web Vitals, WCAG 2.2 AA and security headers - with checks that run in CI.
• Build the measurement layer with the growth team: GA4 events, server-side conversions and the CRM integrations that show which leads closed.
• Review pull requests, pair with two mid-level engineers and write the handover notes clients keep.

Requirements

• Six or more years building for the web, including three or more with React and TypeScript in production.
• Depth in the Next.js App Router: Server Components, static generation, caching and on-demand revalidation.
• Sound relational data design and SQL - Postgres preferred.
• A testing habit: unit tests, end-to-end tests in Playwright and accessibility checks with axe.
• Clear written English - you will explain trade-offs to clients who are not engineers.

Nice to have

• Payload CMS, or another headless CMS such as Sanity, Strapi or Contentful.
• CRM integrations: HubSpot, Zoho, Salesforce or a custom API.
• An LLM feature in production, such as retrieval-augmented search over a client s own documents.
