We are looking for a Senior Full-Stack Engineer with a strong backend lean to join the team that builds and evolves the platform powering this experience. NET system with Vue/Nuxt frontends, SQL Server-heavy data operations, Github/Azure DevOps-driven deployments, and async integration workflows connecting multiple internal services.
This is a senior role where autonomy, ownership, and technical leadership are central. You will own complex backend systems and full-stack features end-to-end — from specification refinement and architectural decisions, through implementation, to production monitoring and incident resolution. You will work on real production systems where SQL performance, distributed reliability, and integration correctness matter daily.
We have fully embraced AI-based spec-driven design , integrating AI throughout the entire software development lifecycle — using skills, rules, multi-agent workflows, and automation for code review, testing, and code analysis. It’s how we work.
Your work directly enables researchers worldwide to collaborate, publish openly,



and push science forward.
Science advances fastest when researchers can collaborate across boundaries — institutional, geographic, and disciplinary. Research Topics are how Frontiers makes that happen.
Each Research Topic is a themed collection of peer-reviewed articles built around an emerging or critical area of science. The Research Topic Management (RTM) application is the platform that makes this possible at scale. It supports the full lifecycle — from the moment a researcher proposes a topic, through editorial coordination, contributor recruitment, and submission tracking, all the way to publication and closure. Design, develop, and maintain scalable, high-performance web applications using .NET, Vue.js, and Nuxt.
Modernise and replace legacy systems — including migrating older Angular applications to our current Vue and Nuxt stack.
Own full-stack projects end-to-end, from specification refinem
