Job description

At AKQA (part of WPP), we believe in the imaginative application of art and science to create ideas, experiences, and stories that move people and brands forward. With an entrepreneurial and collaborative approach, we craft culturally resonant work that blends creativity, storytelling, design, technology, and innovation to create meaningful impact.

In the heart of innovation, AKQA Sweden thrives. We are privileged to collaborate with a fantastic portfolio of clients, including Volvo Cars, Google, Volvo Penta, H&M, IKEA, and more. Each partnership is a shared pursuit of creating transformative digital products and services tailored to their distinct needs and aspirations. We are in relentless pursuit of the beyond, shaping the future with our clients, our people, and our planet at the core. Our work is not just our profession, it's our passion, and our commitment is to a future where everyone has the opportunity to shine. We are not just creating for today: we are creating the Future. Faster.

Working in the Tech team connects you with talented experts across disciplines who are passionate about delivering work of the highest quality and creating maximum value for our clients.

You should be an established fullstack engineer, fluent in modern headless web development end-to-end. You build best-in-class applications across the frontend, API layer, and data sources using a serverless-first, composable architecture.

AKQA is a proud member of the MACH Alliance, and we build completely headless, modern web solutions without the overhead of legacy monoliths or self-hosted infrastructure.

ROLE REQUIREMENTS

• Hands-on Delivery: Lead hands-on development on medium-to-large scale client projects.

• Cross-Disciplinary Collaboration: Work closely with UX, Design, Strategy, and Delivery to solve implementation challenges and turn creative visions into performant code.

• Client Alignment: Understand client business goals to architect and implement the right technical solutions.

• Engineering Quality: Own code quality end-to-end, ensuring solutions are accessible (a11y), performant, secure, and thoroughly tested.

• Modern Ways of Working: Active practitioner of Lean & Agile methodologies (Scrum/Kanban) with a focus on continuous delivery and improvement.

• Frontend & Frameworks: Advanced TypeScript / JavaScript (ESLatest), HTML5, Accessibility (a11y), and production-scale mastery of Next.js and React.

• Headless & Composable Web: Experience building with headless CMS platforms like Contentful, Strapi, or Sanity, and search/indexing tools like Algolia.

• Backend & Data: Building light serverless API routes in Next.js, experience with Hasura for GraphQL backends, and hosted databases like Neon Postgres or cloud (No)SQL.

• Platform & Hosting: Deployment on Vercel; familiarity integrating with client enterprise cloud environments (Azure, AWS, or GCP) when client requirements dictate.

• AI-Assisted Workflow: Comfortable using AI developer tools (Cursor, Claude Code, GitHub Copilot) and leveraging the Vercel AI SDK for building AI-driven features into web apps.

• Testing & Performance: CI/CD pipelines, automated testing (Vitest, Playwright, Cypress), performance profiling, and multi-locale internationalisation (i18n).

• Mobile app development using React Native with Expo (Expo-managed workflow) is beneficial.

• E-commerce integrations and payment gateway experience is beneficial.

• Experience with web animation tools such as Framer Motion, GSAP, and CSS animations is beneficial.

We look for self-starting technologists who adapt quickly across a modern web landscape. The technologies above outline our most commonly used technologies at AKQA Sweden; if you have experience with comparable alternatives, that is not a blocker to success.
