What You’ll Do

• Define and implement architectural patterns for distributed, large‑scale backend systems.
• Write robust, maintainable software and contribute across the entire development lifecycle.
• Partner with product, UX, and cross‑functional engineering groups to clarify technical needs and break down complex initiatives.
• Establish engineering guidelines around testing, reviews, documentation, and long‑term code quality.
• Provide mentorship, pairing, and technical guidance to help engineers grow their expertise.
• Diagnose and resolve issues involving throughput bottlenecks, service availability, and system reliability.
• Contribute to platform‑wide modernization efforts and long‑range architectural planning.
• Evaluate emerging frameworks, tools, and methodologies to continuously improve our engineering velocity.
• Lead or participate in significant cross‑team efforts, modernization projects, and technical deep dives.

Required Background

• Degree in Computer Science, Engineering, or equivalent professional experience.
• 10+ years building production‑grade software systems.
• Strong proficiency in at least one of Python, Java, or Go.
• Hands‑on experience designing distributed systems, service‑oriented architectures, and cloud‑native platforms.
• Solid knowledge of REST‑based service design, event‑driven communication, and asynchronous processing patterns.
• Prior experience deploying and running services on Google Cloud Platform.
• Strong grounding in algorithms, data structures, and software design fundamentals.
• Familiarity with CI/CD pipelines, automated testing, and modern Git workflows.
• Ability to make pragmatic architectural choices, reason about trade‑offs, and communicate decisions clearly to diverse audiences.
