The Opportunity

- Apply established coding standards, architectural patterns, SOLID principles, and unit/behavioral test automation practices to directly contribute to product development.
- Own the architecture for medium-to-high complexity .NET-based features and system-level functionality,



balancing new development with support of existing functionality.
- Build reusable code and libraries for future use.
- Translate complex Product requirements into scalable, performant, and well-architected technical designs; lead architecture and design reviews and critiques for the team.
- Evaluate architectural trade-offs — build vs. buy, monolith vs. microservice, sync vs. async — and make sound, well-reasoned decisions that hold up as the system scales.
- Lead or contribute to the overall engineering architecture beyond your own team's boundaries, and act as a go-to for diagnosing and resolving system-level challenges — scalability bottlenecks, cross-service integration issues, and reliability risks that span multiple components.
- Optimize services for maximum speed and scalability.
- Provide technical leadership and mentorship to junior and mid-level engineers while continuing to deliver high-quality code personally.
- Collaborate with team members and stakeholders; occasionally engage with customers or external teams, including customer escalations as needed.
- Work with development and product teams to understand, estimate, and refine requirements for product features and stories.
- Perform code reviews and help set the bar for best practices and coding standards across the team.
