Role Overview

As a Backend Architect, you are a critical individual contributor and architectural leader within our engineering organization.

• Ensure the performance, quality, and responsiveness of applications
• Collaborating with a mature, interdisciplinary dev team, engineering leaders, and architects to design and deliver high-performance, scalable, and reliable architecture
• Understand clear sub-system boundaries, and make recommendations on where functionality belongs across different sub-systems
• Develop and maintain code quality standards and enforce them across the org
• Proactively identify and drive architectural enhancements and strategic refactorings that improve system scalability, performance, and long-term maintainability.
• Design and implement automated tests at the most effective architectural layer to maximize signal, minimize brittleness, and ensure long-term maintainability.
• Conduct code reviews and architectural reviews for features developed by other members of the team
• Lead code and architectural reviews to ensure alignment with system design principles, promote engineering excellence, and elevate the quality and resilience of team-delivered features.
• Maintain and improve our continuous integration and development environments
• Being a mentor for other engineers across the organization

• Proven success applying Domain-Driven Design (DDD) principles across multiple teams or domains
• Experience in architecting and building event-driven systems using distributed messaging tools (i.e. Kafka, SQS)
• Experience with defining and improving CI/CD pipelines (e.g., Jenkins, Gitlab, etc) and automated testing strategies (e.g., e2e, canary tests, integration tests, etc)
• Expertise in scalable API design and management (i.e. RESTful APIs; GraphQL is a plus)
• Strong background in system observability practices (logs, metrics, tracing) and performance diagnostics
• Bachelor’s degree in Computer Science, Engineering, or related field, or equivalent work experience
