Full Stack Software Engineer

Software Engineering PositionThe 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 DoDesign, build, and maintain backend services and APIs using C# and modern.NETOwn features across customer-facing systems, billing workflows, and internal toolingBuild APIs and application workflows that support account management, permissions, billing, and service lifecycle operationsContribute to front-end applications in React and TypeScript, as well as internal applications built with BlazorIntegrate with third-party systems and infrastructure platforms that support core business and operational workflowsWork with asynchronous, real-time, and event-driven application patternsContribute to analytics and data workflows across transactional and high-volume systemsImprove software quality through code reviews, testing, documentation, and shared engineering standardsSupport production readiness through observability, troubleshooting, and operational improvementsCollaborate across engineering, operations, support, and other stakeholders to deliver practical solutionsBasic Qualifications3+ years of professional experience building production software with C# and modern.NETStrong backend engineering fundamentals, including API design, data modeling, debugging, performance, and secure coding practicesExperience building and maintaining APIs and integrating with external systemsExperience working with SQL databases, including schema design and query optimizationAbility to contribute across the stack, including front-end development in React and TypeScriptFamiliarity with modern engineering workflows including Git, code reviews, testing, and CI/CD practicesStrong ownership mindset, including the ability to work through ambiguity and follow through on improvementsComfortable collaborating across functions and supporting production systems responsiblyComfortable working in a fast-paced, results-oriented environmentPreferred QualificationsYou do not need all of these—depth in a few areas plus strong fundamentals is sufficient:Experience with distributed systems, microservices, or asynchronous workflowsExperience with messaging, background processing, or event-driven systemsExperience with real-time application patternsExperience building applications with BlazorExperience with analytics or high-volume data systemsFamiliarity with containerized deployments and modern delivery practices, including Kubernetes, Helm, GitOps, and CI/CD pipelinesExperience with observability and production diagnostics, including logs, metrics, traces, and related toolingExperience integrating with identity, billing, or other external platformsExposure to infrastructure, hosting, cloud, or hardware-adjacent software systemsExperience working in environments with security and compliance expectationsCuriosity and willingness to work in a primarily C# ecosystem that occasionally touches adjacent technologiesProduct-minded approach to engineering, with an understanding of how technical decisions shape user and operator experienceCompensation and BenefitsHealth, Dental, and Vision Insurance401(k) with company profit sharingPTO and 11 Company Paid HolidaysLocationPreference given to full-time onsite candidates in Pittsburgh, PA, followed by hybrid candidates.
