You'll take ownership of the application's server-side layer while also collaborating closely with front-end developers on product delivery. The role offers substantial technical responsibility, from data access and authentication to complex business logic and third-party integrations. You'll work with a modern stack including Next.js, TypeScript, Tailwind, and shadcn, with AI tools integrated into the development workflow. The environment is fast-paced, autonomous, and focused on shipping high-quality software rather than basic CRUD development. This is an opportunity to become a key technical contributor to a growing product while helping shape its continued evolution. Accountabilities: * Own the application back end integrated directly into the Next.js application, including Server Actions and API Routes. * Design and manage efficient data access and the underlying application data layer. * Develop and maintain third-party integrations and authentication mechanisms. * Implement and optimise complex business logic, including credit management, job pooling, and API timing or delay management. * Collaborate closely with front-end developers to support seamless integration and ensure consistent product experiences. * Contribute directly to the product roadmap and deliver features aligned with business and user needs. * Act as a technical contributor who proactively proposes improvements and solutions rather than simply executing predefined specifications. * Write clean, maintainable, robust, and sustainable code that can evolve with the product. * Investigate and address performance challenges to ensure a reliable and responsive application. * Integrate AI-powered development tools into the engineering workflow while applying appropriate technical judgement to their output. * Communicate effectively within a fully remote team and maintain strong alignment across development activities. * Remain adaptable and, when required, contribute to other products within the wider SaaS portfolio. ## Related Videos - [GraphQL + Apollo + Next.js: A Lovely Trio](https://www.wearedevelopers.com/videos/311-graphql-apollo-next-js-a-lovely-trio) - [Rest API Antipatterns](https://www.wearedevelopers.com/videos/100208-rest-api-antipatterns) - [Level up your Angular CSS with Tailwind CSS](https://www.wearedevelopers.com/videos/640-level-up-your-angular-css-with-tailwind-css) - [Web development best practices in 2021](https://www.wearedevelopers.com/videos/280-web-development-best-practices-in-2021) - [From Zero to Hero: NextJS 13 and Tailwind CSS for Beginners](https://www.wearedevelopers.com/videos/766-from-zero-to-hero-nextjs-13-and-tailwind-css-for-beginners) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) ## Related Articles - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Frontend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/195-frontend-developer-salary-in-germany-2023) - [7 Most Popular Web Developer Jobs in Europe](https://www.wearedevelopers.com/magazine/163-7-most-popular-web-developer-jobs-in-europe)
