Cogneet s Software & Technology practice builds the websites, CRMs and web apps our clients run their business on. As Senior Full-Stack Engineer you lead two or three builds at a time in Next.js and TypeScript, from the content model to production.
It is a hands-on role in a small senior team: you write code most days, review your colleagues pull requests and join client workshops with the strategists and performance marketers who will use what you build.
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.
- Explicit 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.
