## Description

As a Senior Software Engineer in the Infrastructure R&D team, you will lead development of high-performance, on-device medical software applications that securely connect to cloud for telemetry, command & control, remote diagnostics, and over-the-air updates. You will collaborate closely with a multi-functional team of systems, hardware, firmware, quality, and regulatory partners to deliver safe, reliable, and scalable software that directly impacts patient outcomes., * Experience with relational databases and embedded databases such as SQLite, including schema design, data modeling, and data normalization. Strong proficiency in writing, optimizing, and debugging SQL queries.

 * Develop concurrent, multi-threaded components and services using REST APIs and databases, with an architecture that supports evolution and versioning.
 * Design and implement secure device-to-cloud connectivity using modern, secure technologies like IoT, authenticated APIs.
 * Use secure coding principles to ensure cybersecurity and patient safety with appropriate technologies and cybersecurity processes. Examples: X.509 device identity, mutual TLS, certificate rotation, secure storage (e.g., integration with Key Vault), threat modeling, and least-privilege access.
 * Build cloud-connected backends and integrations in Azure or similar cloud environments (Functions, App Service, containers where appropriate) to support telemetry ingestion, command routing, and fleet operations.
 * Drive software quality through unit/integration/system tests (including hardware-in-the-loop), profiling, observability (structured logging, metrics, traces), and CI/CD integration.
 * Contribute to regulatory documentation, traceability, and V&V aligned with IEC 62304, ISO 14971, and related guidance; support submissions (e.g., FDA 510(k)) as needed.
 * Collaborate in Agile/Scrum workflows, mentor junior engineers, and lead design/code reviews to sustain long-term maintainability., * Strong proficiency in full-stack C#/.NET development, object-oriented design, and core CS fundamentals (data structures, algorithms).
 * Demonstrated expertise in multi-threaded/concurrent programming, asynchronous patterns, performance optimization and database read-write operations.
 * Hands-on experience developing on embedded Windows targets (e.g., Windows IoT/Windows services), including integration with device controllers and peripherals.
