What is a senior network engineer?

Senior Network Engineers are experienced IT professionals responsible for designing, implementing, and managing complex computer networks within organizations. They oversee network infrastructure, troubleshoot issues, ensure network security, and optimize performance. Typically, they lead network projects, mentor junior staff, and collaborate with other IT teams to support business operations. Their expertise covers a range of technologies, including routers, switches, firewalls, and cloud networking.

What does a senior network engineer do?

A senior network engineer builds and maintains data communication networks for a company or organization. As a senior network engineer, you have several years of industry experience and lead a team of junior network engineers and network administrators to ensure both the local area network (LAN) and wide area network (WAN) are functioning properly. Your job duties include installing software and hardware, creating a layout plan for cables, and troubleshooting and solving problems that arise with the networks for which you are responsible.

What are the key skills and qualifications needed to thrive as a senior network engineer, and why are they important?

To excel as a Senior Network Engineer, you need a deep understanding of network architecture, protocols, security, and typically a bachelor's degree in computer science or a related field. Expertise in configuring and troubleshooting routers, switches, firewalls, and experience with tools like Cisco IOS, Juniper, or cloud networking platforms, along with certifications such as CCNP or CCIE, are highly valued. Strong problem-solving abilities, communication skills, and leadership are crucial for designing solutions and collaborating with IT teams. These competencies ensure reliable, secure, and scalable network infrastructures that support critical business operations.

What are some common challenges faced by senior network engineers when managing large-scale network infrastructures?

Senior Network Engineers often encounter challenges such as integrating new technologies into legacy systems, ensuring network security across a growing number of devices, and maintaining high availability while performing upgrades or troubleshooting. Balancing the demands of multiple stakeholders—like IT, security, and business units—can also be complex. Staying updated with evolving protocols and proactively identifying potential performance bottlenecks are crucial parts of effectively managing large-scale environments.

What is the difference between Senior Network Engineer vs Network Administrator?

AspectSenior Network EngineerNetwork Administrator
CertificationsCCNP, CCIE, Cisco certificationsCCNA, CompTIA Network+
Work EnvironmentDesign, implement, and troubleshoot complex networksMaintain and support existing network infrastructure
ResponsibilitiesNetwork architecture, advanced troubleshooting, project leadershipNetwork setup, monitoring, routine maintenance

While both roles involve network management, a Senior Network Engineer focuses on designing and implementing complex network solutions, often leading projects. In contrast, a Network Administrator primarily maintains and supports existing networks, ensuring smooth daily operations.

Job description

Position Title: Senior Software Engineer – Interoperability 

Reports to: Senior Manager Global Software Engineering

FT/PT : Full-time

Location : US Office, Hybrid- Office 3 days a week

Position Summary: Join our dynamic engineering team to help develop our revolutionary radiotherapy products for upright therapy. This role sits at the intersection of medical device software engineering and clinical systems integration, with a primary focus on DICOM-RT interoperability between our treatment system and the broader clinical ecosystem — including Oncology Information Systems (OIS), PACS servers, and other networked medical devices. 

The ideal candidate brings deep hands-on experience with DICOM-RT standards, network-level system integration, and medical device software development under IEC 62304. You will play a key technical leadership role in defining and implementing the interoperability architecture that connects our treatment delivery system to the clinical workflow, working closely with partners, clinical customers, and internal cross-functional teams. 

The position requires flexibility in daily tasks with attention to detail and a self-motivated work ethic. The successful candidate will have demonstrated experience working in cross-functional and cross-disciplinary teams and providing technical leadership in the development of novel products. 

Key responsibilities:

  • Lead the design, specification, and implementation of DICOM-RT interoperability features, including RT Plan, RT Dose, RT Structure Set, RT Image, and RT Ion Plan objects. 
  • Architect and develop network API interfaces enabling communication between the treatment delivery system, OIS (e.g. ARIA, Mosaiq), and PACS servers. 
  • Define and maintain the system’s DICOM Conformance Statement and related integration documentation. 
  • Drive end-to-end integration testing with clinical systems, including HL7/FHIR messaging where applicable. 
  • Perform as a technical lead on significant software development projects spanning interoperability and clinical connectivity. 
  • Write specifications, requirements, design documents, and test protocols for software projects in accordance with IEC 62304 and the company design control process. 
  • Develop safety-critical software for imaging and treatment delivery systems. 
  • Work with external partners and clinical customers to develop, validate, and support system interfaces and integrations. 
  • Contribute to the design and development of service and validation tools for DICOM interoperability. 
  • Provide engineering support to partners, customers, and field service teams. 
  • Support regulatory submissions (e.g. 510(k)) as they relate to interoperability and software. 
  • Contribute to system architecture and software development process improvements. 
  • Mentor less experienced engineers in interoperability standards and medical device software practices. 
  • Manage contractors relating to software component development where applicable. 

Relevant Knowledge and Skill requirements:

DICOM-RT and Clinical Interoperability 

  • Deep working knowledge of DICOM-RT standards: RT Plan, RT Dose, RT Structure Set, RT Image, RT Ion Plan, and related SOP classes. 
  • Practical experience integrating radiotherapy treatment systems with Oncology Information Systems (OIS) such as Varian ARIA or Elekta Mosaiq, and PACS servers. 
  • Proficiency with DICOM networking protocols: C-STORE, C-FIND, C-MOVE, C-GET, DICOM TLS, Storage Commitment, and Worklist services. 
  • Experience developing or maintaining a DICOM Conformance Statement. 
  • Familiarity with HL7 v2 and/or FHIR messaging as used in oncology workflows is advantageous. 
  • Understanding of IHE Radiation Oncology profiles (e.g. RO-PIR, IHE-RO) is a plus. 

Medical Device Software Engineering 

  • Proven experience developing medical device software in compliance with IEC 62304, including software lifecycle planning, classification, architecture, unit testing, and maintenance. 
  • Familiarity with associated standards and guidance: ISO 14971 (risk management), IEC 62443 (cybersecurity), and applicable FDA/CE regulatory requirements for software. 
  • Experience supporting regulatory submissions (510(k), CE Technical File) for software-intensive medical devices. 
  • Experience with design and specification of software systems using UML. 

Networking and Software Engineering 

  • Solid understanding of TCP/IP networking: routing, firewalls, VLANs, TLS/SSL, and network security as it applies to connected medical devices. 
  • Experience with REST and/or gRPC API design and integration in a clinical or embedded systems context. 
  • Strong programming skills in Python and at least one of C++, C#, or Java. 
  • Experience with Linux, shell scripting, and systems-level debugging. 
  • Proficiency with version control (Git), CI/CD pipelines, and software testing frameworks. 

Experience 

  • Minimum 5 years of domain-specific experience in medical device software engineering within radiotherapy, radiation oncology, or a closely related imaging/treatment modality. 
  • 10+ years of total software engineering experience, with demonstrated seniority in at least one prior role, is strongly preferred. 
  • Experience working in cross-functional teams including clinical physics, systems engineering, quality, and regulatory affairs. 
  • Ability to mentor and provide technical leadership to less experienced engineers.
