Job Description: Senior AI Software Development Engineer F5 Digital is executing an enterprise-scale Agentic AI transformation to enable secure, observable, and production-grade AI agents across the organization. We are seeking a Senior AI Software Development Engineer to lead the implementation, rollout, and optimization of high-code agent development and orchestration frameworks, as well as enterprise AI integrations, as part of our Gemini rollout and adoption. This is a highly technical, hands-on engineering role. The Senior Engineer will develop scalable agentic systems, apply robust engineering standards for AI workflows, and support engineering teams across F5 in building production-ready agents using Gemini, Vertex AI, and internal AI platform infrastructure. The ideal candidate has strong backend and distributed systems experience, solid hands-on familiarity with LLM architectures and agent frameworks, and a proven track record of writing secure, high-performance production code. Key Responsibilities: Agentic Architecture & Orchestration • Build and optimize enterprise-grade agent orchestration frameworks supporting tool use, memory, RAG, agentic workflows and automation. • Develop patterns for multi-agent collaboration, event-driven execution, and workflow chaining across enterprise systems. • Implement standards for agent lifecycle management, state persistence, and context engineering. Gemini & Vertex AI Integration • Integrate Gemini models via Vertex AI, ensuring secure, scalable API consumption and robust model routing. • Develop and maintain internal SDKs, abstractions, and reusable components to standardize Gemini usage across F5 teams. • Implement and refine prompt engineering, token efficiency, grounding strategies, and structured output patterns. High-Code Agent Enablement • Develop reference implementations and reusable libraries for high-code agents in Java, Python, Go, or TypeScript. • Implement secure integration patterns for agents interacting with Salesforce, Snowflake, SharePoint, ServiceNow, and internal APIs. • Build and maintain MCP (Model Context Protocol) servers and secure API integration gateways. Observability, Safety & Governance • Build logging, tracing, telemetry, and evaluation pipelines for agent performance and reliability. • Apply safety guardrails including input/output validation, hallucination mitigation, prompt injection defenses, and policy enforcement. • Collaborate with Security to ensure secure data handling, RBAC enforcement, and compliance alignment. Developer Enablement & Technical Support • Guide and support engineering teams adopting Gemini Code Assist, CLI workflows, and internal AI development platforms. • Create high-quality technical documentation, internal libraries, and code samples for developer teams. • Participate in code reviews and provide guidance for AI-enabled applications across F5. Performance & Scalability • Optimize inference latency, parallelization, and cost management strategies across agent workflows. • Implement caching strategies, streaming responses, and batching techniques to improve throughput. • Conduct performance testing and benchmarking of agents/models across different workloads. Required Qualifications • 6+ years of experience in software engineering, with strong experience in distributed systems and backend architecture. • Deep hands-on coding expertise in Python and at least one of: Go, Java, or TypeScript. • Hands-on production experience with LLM-based systems, including prompt engineering, tool calling, RAG, embeddings, and agent frameworks. • Experience with Vertex AI, Gemini APIs, OpenAI APIs, or similar enterprise AI platforms. • Strong understanding of API design, microservices, and cloud-native architectures (Docker, Kubernetes). • Experience building or integrating orchestration frameworks (e.g., LangChain, LlamaIndex, custom orchestration layers). • Familiarity with vector databases, embedding pipelines, and retrieval strategies. • Strong understanding of authentication, authorization, and enterprise security patterns. • Proven ability to build robust, reusable code and clean APIs. Preferred Qualifications • Experience building multi-agent systems or autonomous workflow engines. • Experience with model evaluation pipelines and AI quality metrics. • Familiarity with structured output enforcement (JSON schemas, function calling). • Experience working with enterprise data systems such as Snowflake, Salesforce, ServiceNow, SharePoint. • Knowledge of cost modeling and inference optimization techniques. • Experience contributing to internal developer platforms or SDK ecosystems. What Success Looks Like: A successful Senior AI Software Development Engineer in this role will: • Deliver and optimize a secure, scalable orchestration layer for enterprise agents. • Enable engineering teams to build production-grade high-code agents with clean, reusable components. • Maintain robust observability, evaluation, and safety controls for AI-driven workflows. • Accelerate AI agent rollout by building integrations, SDKs, and ready-to-use reference implementations. Impact • This role will directly contribute to how F5 builds and scales agentic AI across engineering, sales, support, finance, and product teams. • You will build the core technical solutions that enable pro-code AI development while ensuring enterprise-grade reliability, governance, and security.
