About the Company

We are a global market leader in commercial equipment manufacturing, with a portfolio of brands serving hospitality, healthcare, multi-housing, laundromat, and industrial customers worldwide. Our software team builds the connected-product ecosystem that sits on top of that hardware, from the edge gateways on the machines themselves to the cloud services and applications customers use every day. We are an established, profitable organization investing seriously in modern software, with an engineering team distributed globally and remote work built into how we operate.

Position Summary

We are hiring a Senior Software Engineer to design, build, and maintain the backend services and APIs that power our digital product ecosystem, including applications that integrate with and run on edge gateway devices. This is a senior individual contributor role for someone who wants to write production .NET code against real hardware, not just another web tier. You will work directly with architects, firmware engineers, and product managers to turn requirements into resilient, well-tested systems that hold up in the field.

What You'll Do

• Design, develop, and maintain ASP.NET Core APIs and backend services supporting edge gateway and IoT device communication
• Build applications that interface with firmware over TCP sockets and local WiFi using offline-tolerant architectures
• Write clean, maintainable, well-tested code and participate actively in code review
• Troubleshoot and debug complex issues across distributed systems
• Contribute to API specifications, technical documentation, and system design decisions
• Support CI/CD pipeline improvements and DevSecOps practices

Required

• 5–8 years of professional software engineering experience
• Strong, current C# / .NET and ASP.NET Core development experience
• Deep understanding of RESTful API design and integration patterns
• Entity Framework Core or a comparable ORM
• Experience with PostgreSQL and SQLite
• Experience with edge gateway or IoT communication patterns
• Proficiency with Git-based workflows and CI/CD pipelines
• Solid grounding in unit, integration, and end-to-end testing
• Demonstrated daily use of AI-assisted development tools such as Claude Code, Cursor, Windsurf, Codex, or GitHub Copilot, with strong code quality and security standards
• Bachelor's degree in computer science, engineering, or a related field, or equivalent experience

Preferred

• Distributed systems experience
• MQTT, RabbitMQ, or AWS SQS
• AWS cloud services
• Docker and container orchestration
• React.js or another modern frontend framework
• Trunk-based development
