Medical device and healthcare system engineering
Medical work differs from other engineering less in the technology than in the evidence: what you can show about why a decision was made, and what you did to verify it.
Be clear about the regulatory path first
The single most consequential question in a medical project is what regulatory class your product falls into, and it depends on intended use and claims rather than on the technology. A device that displays a heart rate and a device that diagnoses arrhythmia may share hardware and live in entirely different regulatory worlds.
This has to be settled before architecture, because it determines the documentation, verification and design-control burden — and retrofitting design controls onto work done without them is close to impossible. We will be direct about where our capability ends: we engineer to support your regulatory pathway, we are not a regulatory consultancy, and for a Class II or higher submission you want a specialist alongside us.
Reliability as a design property
Watchdogs that actually recover, defined behaviour on every fault rather than undefined behaviour on unexpected ones, and a device that fails into a safe and obvious state rather than a quietly wrong one. Battery and power design with margin, since a monitor that dies silently is worse than one that never worked.
Traceability throughout: which firmware version is on which unit, what changed between them, and what was tested. This is unglamorous record-keeping that becomes extremely valuable the first time a question is asked about a specific device.
Data, privacy and integration
Patient data raises the stakes on ordinary engineering decisions. Encryption in transit and at rest, access control that reflects clinical roles, audit logging of who saw what, and retention policies decided deliberately rather than by default.
Where integration with clinical systems is needed we work to the standards those systems speak. And where AI is involved, we are conservative by policy: models can flag, prioritise and summarise for a clinician, and we will not build something that makes an autonomous diagnostic or treatment decision.
Questions
What people ask before starting
Are you certified for medical device development?
We are an engineering studio, not a certified medical device manufacturer, and we would rather say that plainly than imply otherwise. We build to support your quality system and regulatory pathway, and we work alongside the regulatory specialists and notified bodies who carry that certification. If your project needs a supplier operating under a formal medical quality management system, that is a real requirement and we will tell you rather than take the work.
Can you help decide our regulatory classification?
We can tell you which questions determine it and what each answer implies for engineering cost and timeline, which is genuinely useful early. The determination itself should come from a regulatory professional, and we will recommend getting that opinion before design freeze rather than after.
How do you handle patient data?
Minimise what is collected, encrypt in transit and at rest, control access by clinical role, and log who accessed what. Which specific regime applies — and it varies substantially by jurisdiction — should be established at design time, because data residency and retention obligations shape architecture rather than being configurable later.
Will you use AI in a medical device?
For decision support with a clinician in the loop, yes — flagging, triage, prioritisation and summarisation are genuinely valuable and appropriately scoped. For autonomous diagnosis or treatment decisions, no. That boundary is a deliberate limit on what we will build, not a technical one.

Tell us what you are building
One technical call is usually enough to tell you whether this is straightforward, genuinely hard, or the wrong approach entirely. We would rather say so early than quote for the wrong thing.
