About the company:
Our client is a wellness technology company dedicated to helping organizations build healthier, more engaged, and productive workplaces. It offers customizable employee wellness programs that align with organizational culture, values, and business goals.
The company combines fitness technology, mobile applications, web-based tools, health content, and wellness services such as fitness classes, webinars, and health coaching. Its platform enables employees to track healthy habits, participate in wellness activities, earn rewards, and engage in friendly challenges, helping organizations foster a strong culture of health and well-being.
About the Role:
We're looking for a Senior C# Architect to own the technical architecture of our core platform, spanning legacy ASP.NET MVC/Web API services and modern cloud-native systems. You'll balance hands-on coding with high-level design, guide a team of engineers, and drive decisions on scalability, performance, and modernization including migration paths from .NET Framework to .NET 8+.
Key Responsibilities:
- Own end-to-end architecture for ASP.NET MVC and Web API applications, including API design, service boundaries, and data access patterns
- Lead technical design reviews and set coding/architecture standards across teams
- Drive cloud infrastructure decisions (AWS) compute, networking, storage, caching, and managed database services
- Identify and resolve performance bottlenecks in production systems (SQL Server, IIS, connection pooling, caching layers)
- Design and implement caching strategies (Redis/ElastiCache) to decouple read-heavy workloads from primary databases
- Guide migration strategy from ASP.NET Framework (4.x) to .NET Core/.NET 8+, including hosting model changes (IIS to containerized/cloud-native)
- Architect for high availability, disaster recovery, and horizontal scalability
- Mentor senior/mid-level engineers on system design and code quality
- Collaborate with product and infra teams to translate business requirements into scalable technical solutions
- Own technical documentation, RFCs, and architecture decision records (ADRs)
- Participate in incident response and root-cause analysis for critical production issues
Required Qualifications:
- Deep expertise in C#, ASP.NET MVC, ASP.NET Web API (both .NET Framework and .NET Core/.NET 8+)
- Strong background in RESTful API design, versioning, and security (OAuth2/JWT)
- Proven experience architecting solutions on AWS (EC2, RDS, ElastiCache, Lambda, S3) equivalents
- Solid SQL Server expertise: query optimization, indexing strategy, execution plan analysis, stored procedures
- Experience with distributed caching (Redis) and message queuing (SQS, RabbitMQ)
- Strong understanding of IIS configuration, application pools, and Windows Server hosting environments
- Experience with CI/CD pipelines, containerization (Docker), and infrastructure-as-code (Terraform/CloudFormation)
- Track record of leading legacy modernization/migration projects
- Excellent communication skills able to explain architecture tradeoffs to both engineers and business stakeholders
Preferred Qualifications:
- Experience with microservices architecture and event-driven design
- Familiarity with Entity Framework/EF Core and ORM performance tuning
- Exposure to mobile backend architecture (APNs, push notification systems, mobile API design)
- Experience in health/wellness, fintech, or other regulated/data-sensitive industries
- AWS/Azure architecture certification
What Success Looks Like:
- Reduced latency and improved scalability on high-traffic APIs
- Clear technical roadmap for legacy-to-cloud-native migration
- Fewer production incidents tied to architecture-level issues (connection pooling, caching gaps, DB contention)
- Mentored engineers taking on more architecture ownership over time
