Senior Software Engineer

About the role

WHO WE ARE

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 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.

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
