ppScience advances fastest when researchers can collaborate across boundaries — institutional, geographic, and disciplinary. Research Topics are how Frontiers makes that happen: themed, peer-reviewed article collections where leading researchers from around the world propose a theme, invite contributors, and curate the resulting work into an openly accessible body of knowledge — free for anyone, anywhere to read and build upon. /p pWe are looking for a bSenior Full-Stack Engineer with a strong backend lean /b to join the team that builds and evolves the platform powering this experience. You will work on the bResearch Topic Management (RTM) /b application — a distributed .NET system with Vue/Nuxt frontends, SQL Server-heavy data operations, Github/Azure DevOps-driven deployments, and async integration workflows connecting multiple internal services. /p pThis is a senior role where bautonomy, ownership, and technical leadership /b 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. /p pWe have fully embraced bAI-based spec-driven design /b, integrating AI throughout the entire software development lifecycle — using skills, rules, multi-agent workflows, and automation for code review, testing, and code analysis. From specification to implementation, AI tooling shapes how we architect, build, and iterate, making us faster, more deliberate, and focused on what matters most. This isn’t an experiment. It’s how we work. /p pYour work directly enables researchers worldwide to collaborate, publish openly, and push science forward. /p pThese are not just publications. They are communities of researchers working together toward answers that matter: healthier lives, a more sustainable planet, a deeper understanding of the world we share. /p pThe bResearch Topic Management (RTM) /b 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. RTM gives the teams behind Frontiers the tools they need to turn a scientific idea into open, lasting knowledge — one collection at a time. /p h3bResponsabilities /b /h3 ul liDesign, develop, and maintain scalable, high-performance web applications using .NET, Vue.js, and Nuxt. /li liModernise and replace legacy systems — including migrating older Angular applications to our current Vue and Nuxt stack. /li liOwn full-stack projects end-to-end, from specification refinement through delivery to production monitoring. /li liCollaborate with product managers, architects, and cross-functional teams to gather requirements, assess technical feasibility, and determine the best implementation strategy. /li liWork effectively within a multinational, cross-functional team to deliver software aligned with business needs. /li liWrite clean, maintainable, and efficient code, and uphold engineering best practices across the team. /li liEnsure the quality of delivered solutions through robust testing and review. /li liOptimise applications for performance, scalability, and responsiveness. /li liTroubleshoot and resolve complex technical challenges across distributed systems. /li liLeverage AI tooling to raise the quality, speed, and consistency of engineering work. /li liStay current with emerging technologies and bring fresh thinking to keep our stack modern. /li liMaintain a business-oriented mindset, focused on delivering measurable outcomes for end-users. /li /ul ul li5+ years of software engineering experience, with deep expertise in .NET Core / .NET Framework. /li li3+ years of hands‑on experience with modern frontend frameworks (Vue 3 a plus) — and a solid command of the fundamentals: JavaScript, CSS,
