Why we read it this way (6)
The role is hybrid (Tue/Wed/Thu in-office) at Vanguard's Malvern, PA campus, near Philadelphia. Remote is not available.
The posting requires 8+ years of overall experience and 3+ years of Node.js specifically; the title carries no seniority label, but the scope (mentoring, technical vision, leading design/code reviews) firmly supports Senior.
The Technology Stack section is presented as a flat list without explicit 'Required' vs. 'Preferred' sub-headings. Node.js, TypeScript, NestJS, Visual Studio Code, RESTful Services (Spring Boot/Java on AWS), CI/CD/GitHub Actions, Git/GitHub, and JIRA are treated as required given the firm '3+ years Node.js' gate and the stack being the team's primary tooling. AWS Cloud services (ECS Fargate, EKS, Lambda) and mobile-native tools (Xcode/Swift, Android Studio/Java) are explicitly called out as 'a plus' and are marked preferred accordingly.
Spring Boot and Java appear together as the backing service layer ('RESTful Services (Spring Boot / Java on AWS)'); they are listed as a single skill with Java as an alternative since the JD treats them as a combined context rather than two independent gates.
Degree requirement: the JD states 'Undergraduate degree or equivalent combination of training and experience' (equivalent experience accepted) and 'Graduate degree preferred' — neither constitutes a hard degree gate.
Visa sponsorship is explicitly not offered.
