## Description

About Us Visa is a world leader in payments technology, facilitating transactions between consumers, merchants, financial institutions and government entities across more than 200 countries and territories, dedicated to uplifting everyone, everywhere by being the best way to pay and be paid. At Visa, you'll have the opportunity to create impact at scale — tackling meaningful challenges, growing your skills and seeing your contributions impact lives around the world. Join Visa and do work that matters – to you, to your community, and to the world. Progress starts with you. Job Description Visa's Cyber Analytics and AI Innovation organization builds the security capabilities that let the enterprise adopt Generative AI responsibly and safely. This is an innovation-oriented team: our charter evolves as GenAI threats evolve, and our core service is a growing suite of guardrail services that protects AI applications, LLMs, agents, tools, and data interactions from AI-specific threats. As a Senior Software Engineer, GenAI Security, you'll be a hands-on individual contributor who owns problems end-to-end — from technical design and prototyping through production deployment, monitoring, and support. Because this is an innovation org, you won't be boxed into one feature lane: your work may span detection engines, agent and tool security, evaluation frameworks, or platform integration as priorities shift, and you'll often be handed a problem with real latitude in how you solve it rather than a fixed spec. Essential Functions Build and operate GenAI security systems: design, build, deploy, and maintain production services and APIs that detect and mitigate risks such as prompt injection, jailbreak attempts, sensitive-data exposure, and unauthorized or unexpected tool/agent behavior — spanning LLMs, agents, tools, APIs, MCP servers, plugins, and enterprise data sources. Apply deterministic, policy-driven controls where predictable enforcement matters, and model-based approaches where judgment is needed. Measure and improve: build automated evaluation, testing, and feedback loops, plus production observability (logging, metrics, tracing, alerting, dashboards), so detection quality, latency, and false-positive/negative rates stay visible and auditable — then use that telemetry to close gaps. Integrate and scale: containerize and deploy services with Docker and Kubernetes, and integrate GenAI security capabilities into enterprise applications, model gateways, developer workflows, and cloud or on-premises platforms. Practice secure engineering: apply threat modeling, secure coding, dependency and secrets management, code review, and vulnerability remediation; participate in architecture and design reviews and document decisions, interfaces, and operational requirements clearly. Explore and influence: evaluate emerging GenAI security technologies and frameworks through structured proofs of concept, provide technical guidance to other engineers, and help shape the team's engineering standards and practices. Collaborate and operate: work with engineers, researchers, architects, product managers, and infrastructure teams to translate emerging AI-security risks into product capabilities, and support production releases, incident analysis, and defect resolution. Position Location This position may be based in Ashburn, Virginia, under Visa's hybrid working model. The expectation for days in the office will be confirmed by the hiring manager. No relocation budget is available for this position. Visa requires at least 3 days in office, expectations of these days will be confirmed by your Hiring Manager. Qualifications Basic Qualifications 2+ years of relevant work experience and a Bachelors degree, OR 5+ years of relevant work experience Professional software-development experience building backend services, APIs, platforms, or distributed applications. Experience developing production software using Python, Java, Go, or another modern programming
