**About the Team**

The Delivery team is focused on innovating and streamlining how products and services reach our customers.

**What You’ll Do**

- Design and implement user-facing features for critical web properties at scale, making engineering trade-offs between speed, maintainability, and user experience.

- Own the technical design and execution of features, from initial architecture discussions to debugging production issues.

- Collaborate across disciplines, Product, Design, Data Science, and Backend Engineering, to turn ambiguous business needs into clear, scalable front-end systems.

- Champion front-end engineering excellence, defining and leading the adoption of code health, testing, and design standards within your project area.

- Improve core application performance, efficiency, and system reliability, proactively identifying and tackling areas of technical debt in software and processes within your team.

- Mentor junior and mid-level engineers on best practices, system design philosophy, and navigating cross-functional project dynamics.


**What You’ll Need**

- 7 years of professional software engineering experience, with a focus on large-scale, high-traffic web applications.

- Hands-on experience and proficiency in a modern web framework such as JavaScript, React, VueJS, or Angular, plus HTML and CSS.

- Proficiency in fundamental algorithms and data structures, including hash tables, trees, stacks, queues, linked lists, DFS, and BFS.

- Demonstrated understanding of modern web application architecture and design patterns, and their implications for performance and scalability.

- Advanced English communication skills, written and verbal, to effectively collaborate with globally distributed cross-functional teams.


**Bonus Points If**

- Experience leading the technical direction of complex, cross-functional projects with multiple dependencies.

- Familiarity with back-end systems (e.g., Go, Python, TypeScript) to facilitate collaboration and diagnose full-stack issues.

- Experience with the full project lifecycle, from idea inception and stakeholder engagement to monitoring in production.
