Position Summary

League is seeking a Software Security Engineer to join our Security Engineering org and focus full-time on building internal security tooling and security‑by‑design engineering capabilities across our healthcare platform ecosystem.

This is a highly hands‑on software engineering role focused on developing custom security infrastructure, developer security tooling, and automation systems that strengthen League’s platform security posture at scale. You will work closely with Security, Platform Engineering, Infrastructure, and Product Engineering teams to build tools and workflows that improve secure software delivery, automate security operations, and protect sensitive healthcare and member data.

This is not a governance, audit, or advisory‑only role. We are looking for an engineer who writes production‑quality code, builds scalable systems, and applies strong software engineering principles to solve complex security challenges in a modern cloud‑native environment.

As League continues scaling AI‑native healthcare experiences and enterprise platform capabilities, security engineering plays a critical role in ensuring our systems remain secure, resilient, compliant, and developer‑friendly.

What You will do:

Security Tooling & Platform Engineering

Design, build, and maintain custom internal security tooling used across League’s engineering organization.

Develop automation systems that improve application security, secrets management, identity management, and secure software delivery workflows.

Build developer‑friendly security tooling integrated into CI/CD pipelines and internal engineering platforms.

Create scalable systems for vulnerability detection, remediation automation, policy enforcement, and security telemetry collection.

Secure Software Development

Write secure, maintainable, production‑quality code across backend services, APIs, and cloud‑native systems.

Develop security services and APIs supporting authentication, authorization, secrets management, and access governance.

Build and maintain tooling around OAuth/OIDC flows, token lifecycle management, RBAC, service authentication, and secure session handling.

Build and automate cloud security controls across AWS, GCP, and Kubernetes environments.

Develop tooling for infrastructure security, workload identity, encryption management, and runtime protection.

Partner with Platform Engineering teams to strengthen container security, Kubernetes security posture, and infrastructure hardening.

Improve observability and monitoring for security events, anomalous behavior, and operational risk.

AI & Security Innovation

Build security capabilities that support AI‑native engineering workflows and AI‑powered healthcare experiences.

Evaluate emerging AI‑assisted security tooling and identify opportunities to improve engineering productivity and platform protection.

Develop secure workflows and controls around AI‑enabled systems and sensitive healthcare data usage.

Cross‑Functional Collaboration

Partner closely with Security, Infrastructure, Platform Engineering, Compliance, and Product Engineering teams to drive secure engineering practices.

Translate security concepts into practical engineering solutions that improve developer experience and operational efficiency.

Support security incident response, root cause analysis, and remediation efforts when required.

What You Bring

• 5+ years of software engineering experience with a strong focus on security engineering, platform engineering, or infrastructure security.
• Experience building internal engineering or security tooling in cloud‑native production environments.
• Strong hands‑on backend engineering experience building APIs, services, and automation systems.
• Experience implementing secure authentication and authorization systems in production applications.
• Experience working in regulated or high‑trust environments such as healthcare, fintech, or enterprise SaaS is strongly preferred.
• Experience integrating security tooling into CI/CD pipelines and developer workflows.
• Experience working with Kubernetes and distributed systems in production environments.
• Experience working with AI‑enabled systems, AI‑assisted engineering workflows, or LLM‑based applications is considered a strong asset.
