• Design scalable, maintainable, and secure service architectures. • Identify opportunities for platform-wide improvements, new service development, and reduction of technical debt. • Contribute to long-term platform vision and help shape standards for engineering excellence. • Build backend services using C# and TypeScript for web and background worker applications. • Work with both SQL and NoSQL databases; PostgreSQL expertise preferred. • Design, containerize, and deploy services with Docker and Kubernetes. • Build and optimize cloud infrastructure using AWS or similar platforms. • Implement and maintain CI/CD pipelines, Git workflows, and Infrastructure as Code. • Apply security best practices across applications and infrastructure (secure coding, vulnerability assessments, secrets management). • Ensure reliability and scalability through test automation, performance profiling, and optimization. • Integrate and manage third-party APIs with robust monitoring and management practices. • Explore and implement AI/ML-driven features or integrations into applications. • Act as a technical mentor, multiplying team impact by elevating skills and practices of peers and junior engineers. • Collaborate with Product Managers, other Staff Engineers, and cross-functional teams to define requirements, scope projects, and deliver platform solutions. • Work closely with stakeholders to debug, troubleshoot, and resolve complex backend issues across the stack. • Contribute to engineering culture by modeling ownership, accountability, and a growth mindset.

• Conception, design, and implementation of web applications, APIs, databases, and real-time applications • Optimization and continuous development of our e‑commerce software • Maximize AI leverage: agent orchestration, custom workflows, automated pipelines • Work with Kubernetes, Docker, VS Code, and GitLab

• Design, build, and maintain scalable backend services using Node.js, Express.js, and TypeScript • Develop and maintain frontend features in Angular, working closely with designers to deliver clean, performant UIs • Contribute to API design, ensuring consistency, security, and maintainability • Design database schemas, write migrations, and optimize query performance across PostgreSQL and SQL Server • Participate in system design discussions and help define technical direction for new features • Write well-tested, reviewable code and actively participate in code reviews • Diagnose and resolve performance bottlenecks across the stack • Implement security best practices - JWT auth, rate limiting, input validation, prompt shielding • Own production reliability - PM2 process management, graceful shutdown, health checks, structured logging • Collaborate cross-functionally with product managers, QA, and other engineers in an agile environment

• Author and review patches to the PostgreSQL core engine: performance, features, bug fixes, and security. • Maintain Postgres extensions, both open-source (community projects we depend on) and proprietary (Planetscale-owned). • Review community patches with rigor on correctness, stability, and PostgreSQL coding conventions. • Engage the PostgreSQL community in design discussions, the 5 annual Commitfests, and conferences. • Root-cause Postgres issues affecting Planetscale customers and turn fixes into upstream patches when applicable. • Improve documentation for PostgreSQL and our extensions as part of every change.
