## About the Role

Software Engineering, Administrative Skills, Juniper Networks Product Family, Global Financial Markets, Funding, Artificial Intelligence (AI), Problem Solving Skills, Category Development, Software Engineering, Quality Assurance, * 7+ years of experience in backend and/or full-stack software engineering

 * Strong backend engineering experience with Python and frameworks such as FastAPI, Flask, Pyramid, or Django
 * Experience with relational/NoSQL databases, including schema design, query optimization, and data modeling
 * Experience with cloud-native technologies such as AWS, Docker, and Kubernetes, and infrastructure as code
 * Strong understanding of CI/CD, observability, and operating services in production
 * Comfort working full-stack when the problem calls for it (TypeScript/React experience a plus)
 * Ability to break down complex technical problems and deliver pragmatic, maintainable solutions
 * Strong ownership mindset, with the ability to drive projects independently while collaborating effectively across teams
 * Clear communication skills, with the ability to explain technical tradeoffs to engineering and cross-functional partners
 * Hands-on experience with AI-native development tools (e.g., Cursor, Augment), and demonstrated AI Fluency: a deliberate point of view on when AI is (and isn't) the right tool, adapted code review practices for AI-generated code, and safeguards against over-reliance on AI tooling
 * Bachelor's degree in Computer Science or equivalent work experience
 * Hands-on experience building or integrating AI/LLM-powered systems in production (e.g., RAG pipelines, agent frameworks, evaluation workflows, guardrails, prompt/tool orchestration, or model observability)
 * Comfort operating in ambiguous, fast-evolving technical territory where best practices and patterns are still being established

Nice to Have

 * Background in financial services or fintech
 * Experience with API gateway/infrastructure, security & governance tooling, retrieval and data-access systems, or agent frameworks at production scale
