Position Overview

We are seeking a Senior C#/.NET Developer with deep database ownership experience to join our growing engineering team. This role is intentionally hybrid: you will design and build software while also owning the reliability, performance, scalability, and cost management of our SQL databases.

This position is ideal for a senior engineer who is database-centric but not database-only—someone who enjoys writing production code, building features that interact heavily with data, and taking responsibility for how the database performs in real-world, high-availability environments.

You will work across application code, database architecture, and Azure infrastructure, partnering closely with product and engineering leadership to deliver scalable, reliable systems.

- Monitor and proactively address performance bottlenecks, deadlocks, blocking, and resource contention
- Own database cost management in Azure, including sizing, scaling strategies, and cost optimization
- Ensure data integrity, security, and operational excellence throughout the application lifecycle

Software Development & Feature Delivery

- Design, develop, and maintain enterprise-grade applications and services using C# and .NET
- Build application features that interact deeply with the database, balancing correctness, performance, and maintainability
- Develop and maintain RESTful APIs and backend services that integrate with internal and third-party systems
- Participate in architectural discussions and influence technical direction across the stack
- Perform code reviews and mentor team members on best practices in both application and database development
- Troubleshoot and resolve complex issues across application, database, and infrastructure layers

Azure Cloud & DevOps

- Design and operate solutions using Microsoft Azure, with a focus on reliability and observability

- Work with monitoring, logging, and alerting to ensure system health and rapid issue resolution
- Collaborate on infrastructure decisions that impact scalability, performance, and cost
