Senior Full Stack Engineer (Core)

About the role

Join Rocket Money as a Senior Full Stack Engineer, where you'll build and operate core services and platforms that power foundational systems like authentication, data privacy workflows, AI enablement, and internal tooling. You'll own projects end-to-end, partner closely with product engineers, data teams, and operations partners, and improve reliability and observability across critical workflows. The ideal candidate has 7+ years of experience with Node.js/TypeScript, React (or similar framework), and Postgres (or similar relational database). Key missions: Construire et exploiter des services et des plateformes Core qui alimentent des systèmes fondamentaux tels que l'authentification, les flux de travail de confidentialité des données, l'activation de l'IA et les outils internes.. Posséder des projets de bout en bout : définition du problème, conception technique, mise en œuvre, déploiement et fiabilité continue.. Collaborer étroitement avec les ingénieurs produit, les équipes de données et les partenaires opérationnels pour créer des systèmes sûrs, évolutifs et agréables à utiliser. Profile: - The ideal candidate is local to and interested in working from any of our offices (Silver Spring, NYC, SF, Miami, Denver) local to them 1-2x per week - You are highly autonomous. You can take an ambiguous problem, align with stakeholders, and drive it to a reliable production outcome - You understand how observability impacts reliability and enjoy digging into the details to solve performance, data accuracy, and user experience issues - You’re effective in a large organization, building trust across teams, untangling ownership and dependencies, and maintaining momentum from ambiguity through execution - You are an early adopter of AI-assisted engineering workflows and consider these tools a core part of how you ship. You use tools like Claude Code, Cursor (or similar) to accelerate exploration, implementation, debugging, and iteration while maintaining strong engineering judgment - You have a collaborator’s mindset and dig deep to understand nuanced and multi-faceted problems and tenaciously break them down into tractable pieces. You love giving and receiving feedback, and considering new and novel ideas - You're not just interested in what you're building, but also why you're building it. You want to see the bigger picture of how the software you‘re building is benefitting our users - You have 7+ years of professional experience working with some combination of Node.js/TypeScript, React (or similar framework), and Postgres (or similar relational database). Experience with GraphQL is a plus - AI enablement / LLMOps: model gateways, prompt tooling, provider integrations - Privacy & sensitive data: access requests, deletion workflows, least-privilege patterns - Auth & identity: Auth0, OAuth, SSO, session management
