Upstart is a leading AI lending marketplace partnering with banks and credit unions to expand access to affordable credit. As we transitioned to being a public company, we’re now poised to leverage our domain expertise and revolutionize every aspect of lending and credit risk evaluation. We’ve recently expanded our offerings to include automobile refinancing and we plan to take on more verticals as the business grows.

📋 Description

• Define and drive Upstart’s infrastructure security strategy, aligning secure-by-default principles with business priorities, regulatory expectations, and Upstart’s cloud-native engineering roadmap. • Own the security roadmap for cloud, platform, compute, and deployment environments, partnering with infrastructure, platform, SRE, and product engineering leaders to reduce risk across multiple organizations. • Lead security architecture reviews for critical infrastructure initiatives, influencing technical decisions in areas such as cloud IAM, Kubernetes, container security, network segmentation, secrets management, CI/CD, and infrastructure-as-code. • Identify and reduce systemic infrastructure security risks by designing durable preventative controls, guardrails, and automation that improve security outcomes across engineering teams. • Establish standards and patterns for production access, service identity, workload trust, infrastructure hardening, vulnerability management, and secure operational practices. • Partner with engineering teams to improve the security of AI-assisted developer workflows and GenAI-enabled systems, including agentic tooling, coding assistants, and internal AI integrations that interact with production or sensitive environments. • Serve as a senior technical authority during high-severity security or production incidents, driving root cause analysis, risk-based prioritization, and long-term architectural improvements. • Elevate infrastructure security maturity across Upstart by mentoring engineers, influencing senior stakeholders through clear risk communication, and helping teams build secure systems with less friction.

(Preferred) • Experience owning a security roadmap for a technical domain that spans multiple teams or organizations. (Preferred) • Experience with Kubernetes security, service-to-service trust models, workload identity, runtime security, or cloud-native network controls. (Preferred) • Experience improving cloud security posture management, hardening baselines, drift detection, or infrastructure vulnerability management programs. (Preferred) • Experience building or scaling infrastructure security programs, including defining metrics, maturity models, and risk-based prioritization frameworks. (Preferred) • Familiarity with security considerations for AI-assisted engineering workflows, including code generation, code review tooling, agentic automation, and sensitive data exposure risks. (Preferred) • Experience partnering with Legal, Risk, Compliance, or Audit teams to operationalize security controls in a regulated environment.
