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., 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., * 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. ## Description * 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. ## Related Videos - [ZEISS & Microsoft - Building the Next Generation Medical Ecosystem in the Cloud](https://www.wearedevelopers.com/videos/424-zeiss-microsoft-building-the-next-generation-medical-ecosystem-in-the-cloud) - [From Bedside Beeps to Interoperable Bytes – Getting your medical devices ready to talk the IEEE 11073 language](https://www.wearedevelopers.com/videos/771-from-bedside-beeps-to-interoperable-bytes-getting-your-medical-devices-ready-to-talk-the-ieee-11073-language) - [ChatGPT and Java: A Match Made in Heaven or Hell?](https://www.wearedevelopers.com/videos/536-chatgpt-and-java-a-match-made-in-heaven-or-hell) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Beyond UML: Making Sense of AI-Generated Code through Visual Architecture](https://www.wearedevelopers.com/videos/2102-beyond-uml-making-sense-of-ai-generated-code-through-visual-architecture) - [Git for Code Reviews](https://www.wearedevelopers.com/videos/429-git-for-code-reviews) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering)
