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.

Key Responsibilities

• Design, evolve, and optimize database schemas, indexes, queries, and stored procedures to support high‑performance application workloads.
• Own database performance tuning, query optimization, and capacity planning across environments.
• Manage availability, backup/restore, disaster recovery, and survivability strategies in Azure SQL.
• 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.
• 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.
• Design and operate solutions using Microsoft Azure, with a focus on reliability and observability.
• Support CI/CD pipelines and deployment practices using Azure DevOps.
• Work with monitoring, logging, and alerting to ensure system health and rapid issue resolution.
• Collaborate on infrastructure decisions that impact scalability, performance, and cost.

Required Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, or equivalent experience.
• 7+ years of professional experience in C# / .NET software development.
• Strong written and spoken English (C1 or C2 proficiency).
• Strong SQL Server / Azure SQL expertise, including advanced T‑SQL, stored procedures, query optimization, indexing strategies, execution plan analysis, performance tuning, and troubleshooting.
• Proven experience owning database operations, backup, restore, high availability, disaster recovery, performance monitoring, scaling, and cost and capacity management in Azure.
• Expert‑level proficiency in C#, .NET Core, and .NET Framework.
• Experience building and maintaining RESTful APIs.
• Experience with Microsoft Azure services, including App Services, Functions, and Storage.
• Front‑end experience with Angular (7–17).
• Familiarity with Agile / Scrum development methodologies.
• Proficiency with Git and Azure DevOps.
• Excellent communication skills, with the ability to explain complex technical topics.
• Strong analytical and problem‑solving abilities.
• Ability to work independently and take ownership of critical systems.
• High attention to detail and commitment to quality and reliability.
• Collaborative mindset with experience working in cross‑functional, distributed teams.
• Bonus: Microsoft Azure certifications (Developer Associate, Solutions Architect, or similar).
• Bonus: Experience with Plivo or Twilio.
• Bonus: Experience with message‑based systems (Azure Service Bus, RabbitMQ, etc.).
• Bonus: Strong understanding of DevOps practices and production operations.
• Bonus: Experience working in HIPAA‑regulated environments.

What We Offer

• Competitive salary commensurate with experience.
• Opportunity to own critical systems and influence architectural decisions.
• A collaborative engineering culture that values quality, accountability, and continuous improvement.
