What is a senior software engineer?

A senior software engineer designs, codes, tests, and maintains computer software. While these are your primary responsibilities as a senior software engineer, you may also have supervisory duties. These include overseeing a team of junior software engineers or developers. The senior software engineer title is sometimes used interchangeably with senior developer, and positions for both may share similar job duties and responsibilities. In general, software engineers are distinguished from developers in that software engineers apply engineering principles to software development.

What are some common challenges senior software engineers face when mentoring junior team members?

Senior Software Engineers often mentor junior colleagues, which can be incredibly rewarding but also presents challenges. Balancing mentorship with project deadlines can be demanding, as it requires strong time management and communication skills. Additionally, adapting explanations to different learning styles and levels of experience can be tricky. However, effective mentorship helps build a stronger team and can lead to enhanced leadership opportunities for the senior engineer.

What is the difference between Senior Software Engineer vs Software Developer?

AspectSenior Software EngineerSoftware Developer
CredentialsBachelor's or higher in CS or related field; experience often 5+ yearsBachelor's in CS or related field; entry to mid-level experience
Work EnvironmentDesigning complex systems, leading projects, mentoringWriting code, developing features, debugging
Industry UsageUsed across tech companies, startups, enterpriseCommon in software firms, startups, freelance work
Search & ComparisonOften compared for experience level, responsibilitiesCompared for entry-level to mid-level roles

The main difference between a Senior Software Engineer and a Software Developer lies in experience, responsibilities, and scope. Senior Software Engineers typically have more experience, lead projects, and mentor others, while Software Developers focus on coding and feature development. Both roles are essential in tech companies, but the Senior Software Engineer position involves higher-level planning and leadership.

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

To thrive as a Senior Software Engineer, you need advanced programming skills, deep understanding of software architecture, and several years of experience in software development, often supported by a relevant degree. Familiarity with tools like Git, CI/CD pipelines, cloud platforms, and expertise in technologies such as Java, Python, or JavaScript are typically required. Leadership, problem-solving, and effective communication are crucial soft skills for mentoring teams and collaborating across departments. These skills ensure the delivery of robust, scalable solutions and drive successful project outcomes in complex technical environments.

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.
