The Job

The Software Engineering team builds the systems that power Teraswitch's customer experience and internal operations-our customer portal and APIs, billing platform, and the internal tooling that supports high-performance infrastructure at global scale.

This role is backend-leaning, but we value engineers who can think across the stack and understand the user experience end-to-end. You'll work on a mix of mature systems and new functionality, partnering closely with Infrastructure, Operations, Support, and other internal stakeholders to deliver reliable, secure, and scalable software.

We're not looking for a narrow specialist. The right person for this role is a strong all-around engineer who takes ownership, follows through, and looks for ways to improve systems over time. Success in this role requires strong individual contribution, good judgment, and a willingness to engage when needed to improve reliability, support production systems, and help drive issues through resolution.

What You'll Do

• Design, build, and maintain backend services and APIs using C# and modern .NET
• Own features across customer-facing systems, billing workflows, and internal tooling
• Build APIs and application workflows that support account management, permissions, billing, and service lifecycle operations
• Contribute to front-end applications in React and TypeScript, as well as internal applications built with Blazor
• Integrate with third-party systems and infrastructure platforms that support core business and operational workflows
• Work with asynchronous, real-time, and event-driven application patterns
• Contribute to analytics and data workflows across transactional and high-volume systems
• Improve software quality through code reviews, testing, documentation, and shared engineering standards
• Support production readiness through observability, troubleshooting, and operational improvements
• Collaborate across engineering, operations, support, and other stakeholders to deliver practical solutions

Basic Qualifications

• 3+ years of professional experience building production software with C# and modern .NET
• Strong backend engineering fundamentals, including API design, data modeling, debugging, performance, and secure coding practices
• Experience building and maintaining APIs and integrating with external systems
• Experience working with SQL databases, including schema design and query optimization
• Ability to contribute across the stack, including front-end development in React and TypeScript
• Familiarity with modern engineering workflows including Git, code reviews, testing, and CI/CD practices
• Strong ownership mindset, including the ability to work through ambiguity and follow through on improvements
• Comfortable collaborating across functions and supporting production systems responsibly
• Comfortable working in a fast-paced, results-oriented environment

Preferred Qualifications

You do not need all of these-depth in a few areas plus strong fundamentals is sufficient:

• Experience with distributed systems, microservices, or asynchronous workflows
• Experience with messaging, background processing, or event-driven systems
• Experience with real-time application patterns
• Experience building applications with Blazor
• Experience with analytics or high-volume data systems
• Familiarity with containerized deployments and modern delivery practices, including Kubernetes, Helm, GitOps, and CI/CD pipelines
• Experience with observability and production diagnostics, including logs, metrics, traces, and related tooling
• Experience integrating with identity, billing, or other external platforms
• Exposure to infrastructure, hosting, cloud, or hardware-adjacent software systems
• Experience working in environments with security and compliance expectations
• Curiosity and willingness to work in a primarily C# ecosystem that occasionally touches adjacent technologies
• Product-minded approach to engineering, with an understanding of how technical decisions shape user and operator experience
