Fullstack Developer (FTC)

Location: Gothenburg

Department: Technology - Freelance

At AKQA (part of WPP), we believe in the imaginative application of art and science to create beautiful ideas, products and services. With an entrepreneurial and collaborative approach, we design adaptive digital services and applications that capture the imagination, delivering impressive returns for our clients.

Located in Gothenburg, you will take technical ownership of medium to large-scale web platforms, contributing hands-on while guiding architectural and delivery decisions. Working closely with design, UX, product, and client stakeholders, you will translate business goals into robust, scalable technical solutions. You will provide technical leadership through mentoring, code reviews, and pairing, helping to raise engineering standards and quality across the team.

The role involves designing and evolving front-end and back-end architectures with a strong focus on performance, accessibility, security, and maintainability, while proactively identifying technical risks, delivery bottlenecks, and systemic issues. You will champion high-quality engineering practices such as automated testing, CI/CD, and observability, and operate comfortably within Agile, Lean, or hybrid delivery models, adapting processes pragmatically to suit the context.

ROLE REQUIREMENTS

• Strong, modern JavaScript and TypeScript expertise, with deep understanding of browser and runtime behavior.
• Production experience with a primary front-end framework (React-based preferred, e.g. Next.js), and the ability to evaluate alternatives when appropriate.
• Advanced CSS, layout systems, animation, and modern styling approaches.
• js and API-driven back-end development, including REST and GraphQL.
• Cloud-native development on AWS, Azure, or GCP, including serverless and managed services.
• Experience designing and operating microservice or modular architectures.
• Headless CMS platforms (e.g. Contentful, Sanity, Strapi, DatoCMS).
• Strong grounding in web standards, accessibility (WCAG), and internationalisation.
• Relational and non-relational data stores, including cloud-hosted databases.
• Build tooling, automated testing, and CI/CD pipelines.
• Performance profiling, monitoring, and optimisation across the full web stack.
• Hands-on experience building LLM-powered web applications in production.
• Experience with LLM orchestration frameworks such as Vercel AI SDK, LangChain, LlamaIndex, or equivalent, while implementing agents, tools, and function-calling patterns.
• Understanding of prompt design, system instructions, and structured outputs.
• Experience monitoring, evaluating, and iterating on LLM behavior (quality, latency, cost).
• Familiarity with deploying and scaling LLM-backed services in cloud environments.

QUALITIES AND EXPERIENCE

• You are comfortable making architectural trade-offs and explaining them clearly.
• You consider security, privacy, and resilience as first-class concerns.
• You design systems for longevity, not just delivery.
• You can communicate complex technical ideas to non-technical audiences with clarity and confidence.
• You take responsibility for the technical health of the work, not just your individual tasks.
• You can reason about when not to use an LLM, and articulate the trade-offs between probabilistic AI systems and traditional software approaches.
