Job Description
Back End Developer maintaining C#/.NET services, APIs, and data processing applications. Collaborating within a multi-regional team to enhance a global benefits platform.
Responsibilities:
- Create and maintain C# applications and services using best practices and patterns — web applications, Web APIs, Azure Functions, Windows Services, and scheduled/batch processing jobs.
- Design, build, and maintain RESTful APIs (JSON and XML) consumed by web, mobile, and partner integrations.
- Develop and tune SQL Server stored procedures, advanced queries, and data-manipulation processes against large datasets.
- Build and support third-party integrations such as SSO, payment providers, CRM, and email/notification pipelines — including understanding and correctly applying each vendor API’s semantics and contracts.
- Use AI coding agents (Claude Code or similar) as a daily part of the development workflow: feature implementation, debugging, test generation, and pull request preparation.
- Perform substantive code reviews on teammates’ pull requests: verify changes against ticket acceptance criteria, validate assumptions against real data, identify root causes rather than symptoms, and provide clear, prioritized, actionable written feedback — including on AI-generated code.
- Write clear pull request descriptions that document the problem, root cause, fix, and test plan.
- Collaborate with the rest of the engineering team to design and launch new features, including staged rollouts behind feature flags across multiple regions.
- Maintain quality, responsiveness, code integrity and organization.
- Knowledge of code versioning tools such as Git and Azure DevOps.
Requirements:
- A Bachelor’s degree in computer science, engineering or equivalent professional experience.
- 3+ years of experience working with C# and the .NET ecosystem.
- 3+ years of experience working with MSSQL Server: Stored Procs, Advanced Queries, and Triggers.
- Experience working with RESTful APIs using XML and JSON.
- Hands-on experience using AI coding agents (Claude Code, GitHub Copilot, Cursor, or similar) in real production development workflows — required.
- Candidates should be able to demonstrate how they direct an agent through a non-trivial change and how they validate its output.
- Demonstrated code review experience: able to read unfamiliar code, evaluate applications, identify issues, and articulate solutions in writing.
- Data manipulation of varying formats and sizes.
- Experience with Azure (Functions, Blob Storage, Application Insights, serverless architectures) preferred.
- Windows Services and scheduled tasks preferred.
- Experience with multi-tenant or multi-region platforms preferred.
- Experience with Git version control.
- Effective verbal and written communication skills in English.
- Attention to detail and strong analytical skills.
- Proven abilities to take initiative and be innovative.
- Good organizational skills, with a disciplined approach to implementation, support and documentation.
Benefits:
- Medical, Vision, and Dental (Employer paid 75% of monthly contributions)
- Domestic Partner Coverage for all insurance plans
- 100% employer-paid Life Insurance
- 401(K) retirement plan options (including employer contribution)
- Generous Paid Time Off (PTO)
- Generous Paid Paternity and Maternity Leave Policies
- 11 Holidays (Including office closed day after Thanksgiving)
- Professional development opportunities
- Flexible work schedules
- Collaborative and innovative work environment
- Remote-friendly work arrangements
- Employee discount program
- Flexible Spending Account program
- Voluntary Benefit Programs (STD, LTD, Life Insurance, Accident)
