Everything we do centers around people. That means we obsess over how to make the lives of our customers, and their customers, better. And it means we prioritize a diverse F5 community where each individual can thrive.

As a Senior Software Development Engineer bridges software development and quality assurance, writing code to build automated test frameworks, validate complex system architectures, and lead quality strategy across engineering teams.

Core Responsibilities

• AI-Driven Automation Infrastructure: Design, build, and scale end-to-end automated testing frameworks, integrating AI agents for autonomous test generation, maintenance, and self-healing suites.


• Framework Architecture: Develop and maintain scalable test tooling and infrastructure across backend APIs, distributed cloud architectures, and web/mobile interfaces.


• AI & LLM Validation: Establish testing strategies for features powered by Large Language Models (LLMs), focusing on prompt regression, hallucination detection, bias evaluation, and determinism.


• Code & Quality Reviews: Act as a technical subject matter expert (SME) for code hygiene, guiding design reviews, and evaluating testability and architectural health.


• Test Strategy & Coverage: Define and drive test strategies spanning functional, regression, API, performance, load, contract, and chaos/resilience engineering.


• CI/CD Integration: Integrate automated test suites and infrastructure into continuous integration and deployment pipelines (e.g., GitHub Actions, Jenkins, Azure DevOps, GitLab)


• Debugging & Root Cause Analysis: Investigate complex system failures, performance bottlenecks, race conditions, and production issues.


• Cross-Functional Collaboration: Partner with software developers, product managers, and DevOps teams to align acceptance criteria and improve system observability.


• Mentorship: Guide junior and mid-level engineers while advocating for a strong quality-first culture.

Key Requirements & Skills

• Experience: Typically 5 to 9+ years of combined experience in software development, backend engineering, or specialized SDET/test engineering roles.


• Programming Languages: Proficiency in languages such as Python (highly preferred for AI workflows) , Java, TypeScript.


• Automation Frameworks: Hands-on experience with modern tools like Playwright, Selenium, Cypress, or TestNG/JUnit.


• Cloud & Distributed Systems: Familiarity with cloud platforms ( AWS, GCP, Azure ) and containerized or distributed stacks ( Docker, Kubernetes, Kafka, Redis, Cassandra ).


• Infrastructure & Monitoring: Experience using observability and logging tools (e.g., Grafana, New Relic, Elasticsearch)
