Our Agent Resilience platform helps organizations understand how AI agents are performing, evaluate their quality through AI-specific metrics, monitor token usage and cost, and apply runtime controls to help agents make safer and more reliable decisions. Within Cisco, Agent Resilience Team sits at an exciting intersection of AI, observability, security, and infrastructure. Our technology is integrating with platforms such as Splunk AI Observability and has the opportunity to extend across Cisco's broader portfolio-from applications and AI agents to infrastructure, networking, and security. This creates a unique opportunity to build AI experiences that operate across complex, multi-agent enterprise environments. You'll join a fast-moving, collaborative product engineering team that brings together front-end and backend engineers, AI researchers, product managers, and designers. The team owns key areas of Agent Resilience, including observability, AI metrics, tokenomics, budgeting and alerting, and runtime agent control. Your Impact As a Frontend Engineer Agent Resilience Team within Galileo at Cisco, you will build the customer-facing experiences that bring complex AI observability, metrics, and agent-control capabilities to life. You'll translate sophisticated backend and AI capabilities into intuitive enterprise experiences that help customers understand and manage their AI agents. * Design and develop scalable, customer-facing web applications and dashboards for agent observability, AI metrics, token usage, budgeting, alerting, and runtime agent control. * Collaborate with backend engineers, AI researchers, product managers, UX designers, and QA engineers to translate technical capabilities and customer requirements into intuitive product experiences. * Build reusable front-end components and integrate with backend APIs to visualize and interact with complex operational, observability, and AI-related data. * Develop and maintain automated tests to support reliable feature delivery and contribute to the overall quality, scalability, and maintainability of the product. * Participate in architecture discussions, code reviews, troubleshooting, and continuous improvement of front-end engineering practices as the Galileo platform expands across Cisco and Splunk. Success in this role means consistently delivering high-quality customer-facing features while collaborating effectively across disciplines. You will help create experiences that are reliable, scalable, easy to understand, and capable of supporting enterprise customers operating increasingly complex AI environments. ## Related Videos - [How Cisco embraced a DevOps culture within its network engineering team](https://www.wearedevelopers.com/videos/99-how-cisco-embraced-a-devops-culture-within-its-network-engineering-team) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Our journey with Spring Boot in a microservice architecture](https://www.wearedevelopers.com/videos/511-our-journey-with-spring-boot-in-a-microservice-architecture) - [Lessons learned from building a thriving Vue.js SaaS application](https://www.wearedevelopers.com/videos/1666-lessons-learned-from-building-a-thriving-vue-js-saas-application) - [Computer Vision from the Edge to the Cloud done easy](https://www.wearedevelopers.com/videos/263-computer-vision-from-the-edge-to-the-cloud-done-easy) - [Common Mistakes in Vue.js and How to Avoid Them](https://www.wearedevelopers.com/videos/958-common-mistakes-in-vue-js-and-how-to-avoid-them) ## Related Articles - [React Developer Salary [2023]](https://www.wearedevelopers.com/magazine/198-react-developer-salary-2023) - [The Best 7 Frontend Frameworks for Developers in 2025](https://www.wearedevelopers.com/magazine/400-the-best-7-frontend-frameworks-for-developers-in-2025) - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Frontend Developer Salary in The UK](https://www.wearedevelopers.com/magazine/233-frontend-developer-salary-in-the-uk)
