About The Position

TeamViewer provides a leading Digital Workplace platform that connects people with technology—enabling, improving and automating digital processes to make work work better. Our software solutions harness the power of AI and shape the future of digitalization. We believe that our diverse teams and strong company culture are key to the success of our products and technologies, that hundreds of millions of users around the world and around 645,000 customers across all industries rely on. With more than 1,900 employees worldwide, we celebrate the unique perspectives and talents that each individual brings to the table and foster a dynamic work environment where new ideas thrive. The Client Web Shell team owns the foundation that loads, orchestrates, and connects all product features into one seamless experience: the overall features, frontend architecture, build system, and performance of our web application. This role will shape how a large-scale React application is composed and shipped — from module federation and build tooling to AI-powered experiences embedded at the core of the product. This role sits at the intersection of product-facing UI work and deep frontend platform engineering.

Requirements

• 8+ years of production software engineering experience, with strong C#/.NET expertise, solid React skills, and a strong foundation in software engineering principles.
• Deep expertise in distributed systems, including microservices, messaging, consistency trade-offs, and diagnosing failures in high-load environments.
• Experience working with SQL databases, non-relational data stores, cloud platforms, containerized deployments, and event-driven or streaming architectures at scale.
• Regular use of AI coding agents within production codebases, coupled with accountability for the correctness, security, and maintainability of delivered software.
• Proven ability to expose capabilities to AI systems through tool and function interfaces, structured APIs, MCP servers, or similar model-facing integration patterns.
• Strong understanding of common AI model failure modes, including hallucinations, context degradation, prompt injection, non-determinism, and silent regressions, along with effective mitigation strategies.
• Critical evaluation of generated code at scale, with the ability to identify and reject plausible but unsafe outputs while leveraging tests, evaluations, and architectural context to ensure reliability.
• Excellent English communication skills, a collaborative mindset for working with teams across EMEA, and a strong interest in shaping AI-native engineering practices.

Responsibilities

• Design and build scalable .NET services and React frontends across Web Shell, Agentic Ecosystem, and Endpoint Observability domains.
• Build event, telemetry, and audit pipelines covering ingestion, correlation, retention, export, and access control at enterprise scale.
• Expose platform capabilities safely to Tia and third-party agents through MCP tools, typed APIs, and tenancy-aware authorization.
• Deliver production features in a microservices codebase using AI coding agents, contract tests, schema validation, and integration coverage.
• Debug distributed, partly model-driven systems and build the tracing needed to understand non-deterministic behavior.
• Maintain service-layer context for agents, including API contracts, domain vocabulary, architectural decision records, and repository instructions.
• Own performance, scalability, reliability, and AI-assisted cost profiles for the services you ship.
• Partner with product management and EMEA anchor teams to refine requirements and shape architectural decisions.
