Position Overview

We’re looking for a highly skilled Front-end Developer with a strong grasp of modern web technologies and a passion for innovation. You will join an agile, cross-functional team and help evolve Askia’s data-collection platform using a modern full-stack JavaScript/TypeScript toolchain. Your work will focus on building flexible, maintainable, and extensible codebases that stay resilient as features grow.

Tech stack & ecosystem

Our main stack includes Svelte, SvelteKit, TypeScript, JavaScript (ESNext), Node.js, Vite, TailwindCSS, PostCSS, Vitest, Playwright, Storybook, Chromatic, Docker, and Google Cloud .

Development Philosophy

We build modern web applications using:

• Component-Driven Development (CDD) – isolate, document, and test UI components to encourage single-responsibility and reusability.
• Declarative & Reactive Programming – describe what the UI should look like, letting the framework handle the how, which reduces coupling and eases future extensions.
• Universal / Full-Stack JavaScript – leverage a single language across client and server for seamless SSR and API development, promoting clear contracts and predictable dependencies.
• Automated Quality – unit, integration, and visual-regression testing (Vitest, Playwright, Storybook/Chromatic) with CI/CD pipelines, ensuring that small, focused modules can evolve safely.

Responsibilities:

• Develop well-structured, reusable front-end interfaces for Ipsos Askia products according to specifications.
• Write maintainable and easily extendable code and libraries.
• Analyze existing solutions and propose incremental improvements for user experience and performance.
• Provide technical support (installation, administration, configuration, and maintenance) for developed applications.
• Monitor and evaluate emerging web technologies and advise on their potential use to keep designs open to enhancement.
• Debug and resolve issues reported by QA or Product Owners with a focus on clear boundaries and minimal side effects.
• Participate in agile ceremonies and contribute to specifications, development, and testing of the online suite front ends.
• Join technical and architectural discussions to implement loose coupling and clean abstractions.

Requirements:

• 5+ years of experience with front-end technologies and related component-based frameworks (React, Next.js, Vue, Nuxt, SolidJS, Astro). Svelte knowledge is a strong plus.
• 2 years' experience with JavaScript, TypeScript, and Node.js.
• Understanding of unit testing, modular architecture, and scalable design patterns. (Carbon Design System knowledge is a plus.)
• Experience with REST APIs, Git for version control, and basic Docker usage (Kubernetes exposure is a plus).
• Basic database knowledge.
• Excellent English communication skills.
• Collaborative mindset, strong interpersonal skills, and a proactive attitude toward designing for change and growth.

Benefits:

• Flexible Benefits platform (e.g. private pension, Kindergarten support, and more)
• Referral bonus
• Bookster subscription
• Wellhub subscription
• Employee Assistance Program.
