Senior Software Engineer C#.NET in Edinburgh

At Spacelabs Healthcare, we are on a mission to provide continuous innovation in healthcare technology for better clinical and economic outcomes. Our scalable solutions deliver critical patient data across local and remote systems, enable better-informed decisions, increase efficiencies, and create a safer environment for patients.

As a Senior Software Engineer, you will play a key role in the ongoing development and evolution of Spacelabs’ healthcare software portfolio. This role spans both new cloud‑based application development on AWS and significant ongoing work on existing, production systems that are actively used in clinical environments today. Spacelabs is transitioning from predominantly on‑premise and Windows‑based applications toward modern, cloud‑hosted architectures. You will help shape and execute this transition by contributing to the design, development, and deployment of AWS‑hosted services and applications, while maintaining, enhancing, and modernising established products that remain business‑critical—ensuring continuity of service, regulatory compliance, and a strong customer experience.

You will have meaningful influence over how cloud technologies are adopted, including architectural patterns, deployment approaches, security posture, and engineering standards. You will work with stakeholders to translate product and regulatory needs into pragmatic technical plans, while driving improvements to existing applications—addressing customer priorities, technical debt, performance, reliability, and operational resilience.

The successful candidate will bring hands‑on experience with production AWS systems and will thrive in a mixed environment where cloud‑native development, incremental migration, and legacy system enhancement coexist. You will raise the technical capability of the wider team through practical leadership—setting direction, mentoring, strengthening review practices, and modelling high standards of delivery and craftsmanship.

The core application stack is C# / .NET, spanning desktop, browser‑based, and service‑oriented solutions. Experience working in regulated or safety‑critical environments (such as medical devices) is advantageous but not mandatory; you are expected to apply disciplined engineering practices, with a strong focus on software quality, reliability, security, and traceability across the development lifecycle. This role is based on‑site in Edinburgh, with the possibility of hybrid working arrangements.
