This position requires fluent English - do not apply with a non-English profile / resume as it will be automatically filtered. 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

• Database Architecture, Performance & Ownership
  • 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
  • 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
  • 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

• Experience & Education
  • 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)
• Technical Skills (Priority Order)
  • Strong SQL Server / Azure SQL expertise, including
    • Advanced T-SQL
    • Stored procedures and query optimization
    • Indexing strategies and execution plan analysis
    • Performance tuning and troubleshooting
  • Proven experience owning database operations, including
    • Backup, restore, high availability, and disaster recovery
    • Performance monitoring and scaling
    • 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
• Soft Skills
  • 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 Points
  • Microsoft Azure certifications (Developer Associate, Solutions Architect, or similar)
  • Experience with Plivo or Twilio
  • Experience with message-based systems (Azure Service Bus, RabbitMQ, etc.)
  • Strong understanding of DevOps practices and production operations
  • 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
