Staff Software Engineer, Web Frontend - Platform Services

TeamViewer

Ioannina, Greece

Responsibilities

• Lead the design and evolution of our React-based platform architecture, serving as the technical anchor for one of the most demanding and highest-leverage projects in the company.
• Own frontend performance end to end: rendering strategy, bundle optimization, data-fetching patterns, and the observability to prove improvements with real-user metrics (Core Web Vitals, INP, TTI).
• Build and integrate AI-enabled features and infrastructure, including streaming LLM responses, real-time inference-driven UI, agentic workflows, and the state/data patterns that make AI experiences feel fast and reliable.
• Define and champion state management strategy across the platform, choosing the right tool for the job across Redux, Zustand, and RxJS-based reactive patterns, and guiding teams on when and how to use each.
• Evolve our build and developer-experience tooling on Vite, keeping local iteration fast and production builds lean as the codebase scales.
• Partner closely with Product and Design to translate UX intent into technical architecture, advocating for the user in technical decisions and for technical reality in product decisions.
• Mentor senior and mid-level engineers, raise the bar through design reviews, and influence engineering direction beyond your immediate team.
• Make pragmatic build-vs-buy and prioritization decisions informed by business context, considering cost, time-to-market, customer impact, and long-term maintainability.

Requirements

• 8+ years of professional software engineering experience, with deep, hands-on expertise in modern React (hooks, concurrent features, server components are a plus).
• Proven track record designing and scaling frontend platforms or design systems used by multiple teams.
• Expert-level knowledge of state management approaches and their trade-offs. You have shipped production systems with Redux (including RTK), Zustand, and reactive streams with RxJS, and can articulate when each approach is most effective.
• Strong command of frontend performance engineering, including profiling, code-splitting, caching strategies, rendering optimization, and measuring impact with real-user monitoring.
• Experience with modern build tooling, ideally Vite, and a strong point of view on developer experience at scale.
• Hands-on experience building AI-enabled user experiences, including integrating LLM APIs, handling streaming and partial responses, designing UI patterns for non-deterministic systems, or using AI-assisted development tooling thoughtfully in your own workflow.
• Genuine UX sensibility. You understand interaction design, accessibility, and perceived performance, and pay attention to the details that improve the user experience.
• Demonstrated business acumen. You connect technical investments to business outcomes, communicate trade-offs to non-technical stakeholders, and know when a pragmatic solution is more valuable than a perfect one.
• Excellent written and verbal communication skills, with experience driving alignment through documentation, technical specifications, and cross-team collaboration.
• Nice to have: Experience with TypeScript at scale, monorepo tooling (such as Turborepo or Nx), and module federation or micro-frontend architectures.
• Nice to have: Experience with SSR or edge-rendering frameworks and a solid understanding of their performance implications.
• Nice to have: Familiarity with prompt engineering, RAG patterns, or evaluating AI-powered features in production environments.
• Nice to have: Previous experience working on platform, infrastructure, or developer-experience teams.
