Software Engineer, Agentic Systems Engineering - ThousandEyes

Please note that we operate a hybrid working model and this role will require you to work from our offices in Oeiras at least 2 days a week.

Cisco ThousandEyes is a Digital Experience Assurance platform that empowers organizations to deliver flawless digital experiences across every network—even those they don’t own. Powered by AI and an unmatched set of cloud, internet, and enterprise network telemetry, ThousandEyes enables IT teams to proactively detect, diagnose, and remediate issues before they affect end-user experiences.

ThousandEyes is deeply integrated across the Cisco technology portfolio and beyond, delivering AI-powered assurance insights within Cisco’s Networking, Security, Collaboration, and Observability products.

Our team develops internal AI-powered tools that help software engineers work more effectively across the development lifecycle. We build agentic workflows, reusable skills, integrations, and supporting platforms that make it easier for developers to understand complex codebases, implement changes, improve quality, and automate repetitive engineering tasks.

We are a collaborative, product-minded engineering team working at the intersection of software development, developer experience, and applied AI. You will have the opportunity to experiment with emerging technologies, learn from real-world usage, and turn promising ideas into reliable tools used by engineering teams across the organization.

As a Software Engineer you will:

• Design, build, test, and operate AI-powered tools and services for software developers.
• Develop agentic workflows, reusable skills, tool integrations, and orchestration capabilities.
• Integrate AI tools with source control, CI/CD systems, issue trackers, documentation platforms, and internal developer environments.
• Build backend services and APIs that are secure, observable, reliable, and easy to maintain.
• Apply software engineering practices to manage the non-deterministic nature of AI systems, including evaluation, testing, monitoring, and feedback loops.
• Work directly with developers to understand their workflows, identify opportunities for improvement, and iterate based on real-world feedback.
• Contribute to technical design discussions and help evolve the architecture of our AI development platform.
• Improve engineering processes, documentation, and operational practices across the team.

• Software development experience using Python.
• Experience designing, building, testing, and operating backend services or developer-facing tools.
• Hands-on experience designing and implementing APIs within distributed software architectures.
• Practical experience using or developing with large language models, AI coding tools, or agentic AI systems.
• Experience working with Git, automated testing, and continuous integration and delivery workflows.

• Bachelor’s degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience.
• Strong problem-solving and communication skills, with the ability to collaborate effectively in a cross-functional team.
• Experience developing AI agents, reusable skills, tool-calling integrations, prompts, evaluation frameworks, or agent harnesses.
• Familiarity with retrieval-augmented generation, embeddings, context management, and model evaluation.
• Experience building internal developer platforms, command-line tools, IDE integrations, or engineering productivity tooling.
• Knowledge of Kotlin, Java, Go or TypeScript.
• Understanding of Kubernetes, containers, and modern cloud deployment practices.
• Experience with observability, security, privacy, and responsible AI practices.
• Familiarity with relational, document-based, or vector datastores.
