C# ENGINEER JOB DESCRIPTION

A C# Engineer who consistently misses sprint commitments or ships untested code does not stay in the role long. The discipline required here - from peer code reviews to managing technical debt so velocity stays predictable - is what separates engineering teams that deliver from those that stall. This role owns the full implementation cycle: requirements analysis, solution design, development, and production support across enterprise-grade applications built on .NET. Seven or more years of experience is the baseline because the scope demands it.

As the C# Engineer, you translate complex business requirements into secure, well-tested .NET applications while maintaining code quality standards and supporting production systems that end users depend on daily. You operate within cross-functional Agile teams alongside product owners, QA partners, and engineering managers, with scope spanning design-through-deployment responsibilities across enterprise and web application environments.

Career Impact: Engineers who have owned technical debt management, peer review processes, and solution design at this level build a track record that carries real weight when moving into senior architect or engineering lead roles.

Business Impact: The applications this role delivers and sustains handle enterprise-wide workflows and production traffic, meaning code quality decisions made here have direct consequences for system uptime and user experience.

Growth Opportunity: Consistent exposure to TDD, SOLID principles, Agile delivery, and cloud-native microservice patterns gives engineers a skills profile that remains competitive across financial services, government, and product-led software companies.

• Design and develop enterprise web applications spanning requirements definition through production support within Agile delivery cycles.
• Review peer code contributions to enforce architecture patterns, coding standards, and extensibility requirements.
• Manage technical debt across the codebase to keep delivery velocity responsive and predictable for sprint planning.
• Collaborate with product owners and QA partners to translate user stories into tested, deployable software increments.
• Troubleshoot and resolve production incidents for enterprise applications to restore service within acceptable time windows.
• Implement automated unit tests and integration tests to validate new components against functional and non-functional requirements.
• Mentor junior developers and interns on engineering practices including test-driven development and object-oriented design principles.
• Document solution designs, technical specifications, and release notes to keep the team knowledge base current and accurate.

• Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent work experience.
• 5 or more years of professional software engineering experience, with demonstrated ownership of application design through deployment.
• Proven experience designing and developing applications using object-oriented principles and established design patterns.
• Demonstrated experience with relational database development including schema design, stored procedures, and query optimization.
• Experience applying test-driven development practices including unit testing and behavior-driven testing approaches.
• Solid understanding of Agile and DevOps methodologies including sprint planning, backlog grooming, and CI and CD pipelines.
• Experience developing and consuming RESTful and SOAP-based web services within distributed application architectures.

• Experience working within PCI DSS or Sarbanes-Oxley compliance environments requiring control documentation and audit support.
• Background in cloud-native development using containerized microservice architectures and infrastructure-as-code practices.
• Prior experience as a technical team lead or engineering mentor with accountability for team delivery outcomes.
• Mathematical or analytical background supporting work in quantitative, financial, or data-intensive application domains.

• Code review cycle time, measuring how quickly peer reviews are completed and acted upon within sprint windows.
• Defect escape rate, tracking the percentage of bugs reaching production relative to total features shipped per sprint.
• Sprint commitment rate, reflecting the proportion of planned story points delivered without carryover across consecutive sprints.
• Mean time to resolution for production incidents, measuring speed of diagnosis and fix deployment under live conditions.
• Test coverage percentage, indicating the share of new and modified code protected by automated unit and integration tests.
• Typical tools: Version control (commonly Git), issue tracking (commonly Jira or VersionOne), automated testing frameworks (commonly NUnit, MSTest, or SpecFlow)

• Base Salary Range: $105,000 to $145,000 annually depending on seniority and location.
• Bonus: annual performance bonus of 8 to 15 percent of base salary.
• Equity: RSUs or stock options offered at mid-to-senior levels in product companies.
• Health Benefits: medical, dental, and vision coverage for employee and dependents.
• PTO: 15 to 20 days annually plus federal holidays and sick leave.
• Common Perks: Remote or hybrid flexibility, continuing education reimbursement, and home office stipend.
