Software Engineer I

F5 is seeking an entry-level Software Development Engineer (AI) to join its Digital organization and help build solutions across its digital ecosystem. The role focuses on contributing to scalable systems, exploring AI and machine learning technologies, and collaborating with mentors and teammates on coding, testing, documentation, and design reviews.

What you'll do:

• Contribute to real-world projects across the full development cycle, collaborating with the team to deliver solutions that meet project goals
• Work with peers to design, implement, and test code in a collaborative environment, receiving feedback and guidance from senior engineers
• Analyze requirements, test features, and integrate components into applications with support and mentorship
• Create technical documentation for designs and new features, learning best practices in technical writing and communication
• Participate actively in design and code reviews to absorb best practices, understand quality standards, and continuously improve code quality
• Collaborate with your team to explore and develop data-driven solutions using machine learning and AI technologies
• Ask questions, seek clarification, and leverage mentorship to navigate challenges and accelerate your learning

What they're looking for:

• Bachelor's degree in Computer Science, Software Engineering, Information Technology, Computer Engineering, or a related field
• Demonstrated programming experience in Python (preferred) or Java/C++/Go, including building APIs/services, writing tests (pytest/JUnit), and using Git in a collaborative codebase
• Hands-on exposure to machine learning and deep learning concepts and tooling, such as PyTorch (preferred) or TensorFlow/JAX, including training/inference workflows and basic model evaluation
• Familiarity with modern LLM tooling and patterns, such as Hugging Face Transformers, prompt engineering, and retrieval-augmented generation concepts (embeddings + search)
• Exposure to data handling for ML, including common formats and pipelines (e.g., Parquet, basic ETL, and data quality checks)
• Demonstrated knowledge of computer science fundamentals (e.g., data structures and algorithms)
• Must be willing to relocate to Seattle, WA or San Jose, CA if not currently based in one of these locations
• Experience with API development (e.g., FastAPI/Flask, REST/gRPC) and backend fundamentals (auth, pagination, error handling)
• Experience implementing retrieval-driven AI applications using LangChain/LlamaIndex and vector search technologies (e.g., pgvector, Pinecone, Milvus, Weaviate)
• Familiarity with fine-tuning approaches (e.g., LoRA/PEFT) and/or ML experimentation tools (MLflow or Weights & Biases)
• Exposure to containers and modern DevOps: Docker, Kubernetes basics, CI/CD (e.g., GitHub Actions, GitLab CI)
• Observability basics: logging/metrics/tracing (e.g., OpenTelemetry, Prometheus/Grafana concepts)

Benefits:

• Comprehensive health, wellness, and retirement benefits
• Professional development and continuous learning opportunities
• Work-life balance benefits including flexible work arrangements
• Hybrid work environment with periodic in-office collaboration in Seattle
• Mentorship and career growth opportunities within the F5 Digital organization
• Access to F5's employee resource groups and community
• You may also be offered incentive compensation, bonus, restricted stock units, and benefits
