Middleware Software Engineer Job Description
This is a pivotal role that requires connecting embedded firmware systems with higher-level software applications and clinical platforms. The ideal candidate will bring a strong background in C#, Visual Studio, .NET, API development, and real-time device communication within a regulated medical environment.
As a Middleware Software Engineer, you will have the opportunity to work at the intersection of software, hardware, and real-time data systems as part of a highly collaborative engineering team focused on developing advanced technology for critical applications in the healthcare space.
Key Responsibilities:
* Develop and maintain ASP.NET Web API applications for ingesting, processing, and exposing data from medical hardware systems.
* Integrate with hardware device APIs to collect, measure, and analyze ionizing radiation data for quality assurance.
* Implement real-time data streaming using SignalR, allowing clinicians and systems to interact with live device data.
* Maintain and improve Windows Communication Foundation (WCF) services and Windows Services for reliable transmission of data from distributed devices to on-prem servers.
* Build and optimize data storage/retrieval workflows using Entity Framework with SQL Server and MongoDB, including writing and optimizing SQL queries.
* Collaborate with firmware, hardware, software, and medical physics teams to identify system-level requirements and troubleshoot integration issues.
* Develop internal tools and utilities, potentially using WPF, to support operations and product diagnostics.
* Ensure all middleware components comply with FDA regulations and industry standards like IEC 62304, DICOM, and HL7.
* Participate in design reviews, risk analysis, and support testing and documentation required for regulated environments.
* Serve as a technical escalation point for product support teams.
Requirements:
* 7+ years of experience in middleware, backend, or systems software engineering.
* Highly proficient in C#, Visual Studio, and .NET, including ASP.NET Web API and WCF.

* Experience integrating with hardware or embedded systems APIs.
* Proficiency with Entity Framework, SQL Server, and MongoDB, including writing and optimizing SQL queries.
* Experience with real-time communication using SignalR or similar frameworks.
* Familiarity with JSON and XML for data exchange and parsing.
* Prior work with medical devices, oncology/radiation systems, or other regulated industries.
* Strong testing and debugging skills across software and hardware boundaries.
* Excellent documentation practices and communication skills.
Preferred Qualifications:
* Background in radiation oncology, medical physics, or QA of therapy devices.
* Experience developing or supporting dose calibrators, PACS/RIS, or clinical QA software.
* Understanding of FDA 21 CFR Part 820, ISO 13485, IEC 62304, or similar compliance frameworks.
* Prior experience delivering Tier 2 support or collaborating with R&D and product teams.
