• Lead the architecture and development of complex, scalable frontend systems, ensuring modularity, performance, and long-term maintainability. • Design and build high-quality user-facing features using React, TypeScript, and modern CSS, with strong attention to UX and accessibility. • Own project execution end-to-end: define well-scoped milestones, deliver on time with high quality, and operate with minimal guidance. • Collaborate closely with product managers, designers, and backend engineers to shape product direction and technical architecture. • Define and champion best practices across the engineering lifecycle, including coding standards, testing, documentation, and code reviews. • Prototype rapidly, iterate on evolving ideas, and help bring clarity to ambiguous problem spaces. • Mentor engineers, provide technical guidance, and raise the overall bar for engineering excellence and architectural decision-making. • Drive operational excellence by contributing to observability, rollout safety, incident response, and ongoing system reliability improvements. • Diagnose and resolve production issues across the stack, proactively improving systems to reduce operational and on-call load.

• Build efficient, high-performing front-end features in a modern SPA web framework. • Write efficient, clean, readable, fast, testable, documented code. • Deliver new features to production. • Collaborate with internal and external teams and other engineers to deliver a compelling easy-to-use product for the end-user / users. • Work closely with other engineers in a small, informal, remote team environment. • Ship code often in a fast-paced agile environment with continuous deployment. • Mentor and support other frontend engineers. • Work alongside and learn from talented engineers who have worked at leading advertising and technology companies.

• Design and build microservices and serverless applications in the cloud • Implement web application changes and/or build new web applications using the React framework • Work with Product Owner and UX design to understand and create solutions for diverse user requirements • Collaborate in a fast-paced Agile environment • Help our support team triage bugs and troubleshoot production issues

• Develop services and APIs in C# (.NET / .NET Core) following best practices (REST, SOLID, Clean Architecture, Clean Code). • Develop and maintain scalable, accessible React interfaces (Hooks, Context, global state; preferably with TypeScript). • Model data and implement efficient queries in SQL databases (e.g., PostgreSQL, SQL Server, MySQL) and NoSQL (e.g., MongoDB, DynamoDB). • Ensure quality with unit, integration, and end-to-end tests, code reviews, and engineering best practices. • Ensure security (authN/authZ, OWASP Top 10), observability (structured logs, metrics, tracing) and performance. • Promote best practices and actively participate in code reviews and design reviews. • Collaborate with Product, QA, and UX for continuous discovery and delivery (Lean, Agile, Kanban/Scrum).
