Senior Software Engineer

Software Engineer Engineered to outperform, Teraswitch is on a mission to provide high-performance infrastructure services for critical workloads. With 20+ datacenter locations around the world interconnected by our low latency global backbone network, we are the class leader in performance bare metal hosting and are rapidly expanding into additional infrastructure services. 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. A key part of this role is building software that helps provision, manage, and operate physical infrastructure across our global footprint. You'll work on systems that interact with hardware, infrastructure platforms, and operational workflows in addition to more traditional application and API development. 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 across a mix of mature systems and new initiatives, 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 can take on meaningful technical scope, make sound decisions, and help improve systems over time. What You'll Do Design, build, and maintain backend services and APIs using C# and modern.NET Drive the design and delivery of features and systems across customer-facing applications, billing workflows, and internal tooling Build application workflows and make sound technical decisions around integrations, data flow, reliability, and maintainability Contribute to front-end applications in React and TypeScript, as well as internal applications built with Blazor Work with asynchronous, real-time, and event-driven application patterns Contribute to analytics and data workflows across transactional and high-volume systems Participate in production support and on-call responsibilities, including troubleshooting issues and improving operational readiness over time Collaborate across engineering, operations, support, and other stakeholders to deliver practical solutions Mentor other engineers through technical guidance, code review, and day-to-day collaboration Basic Qualifications 5+ 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 designing and building 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 technical judgment and the ability to work effectively through ambiguity Comfortable collaborating across functions and exercising sound judgment in production environments Preferred Qualifications You do not need all of these—depth in a few areas plus strong fundamentals is sufficient: Experience with distributed systems, messaging, asynchronous workflows, or 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 Product-minded approach to engineering, with an understanding of how technical decisions shape user and operator experience Compensation and Benefits Health, Dental, and Vision Insurance 401(k) with company profit sharing PTO and 11 Company Paid Holidays Location Preference given to full-time onsite candidates in Pittsburgh, PA.
