Senior Principal iOS Architect

Insulet Corporation•San Diego, CA

21h•Hybrid

About The Position

The Senior Principal iOS Architect defines the technical vision, architecture, and engineering strategy for Insulet’s iOS mobile application, which serves as the patient-facing controller for a connected insulin delivery system. The app securely connects to insulin pumps and continuous glucose monitors (CGMs) using Bluetooth Low Energy (BLE), issues therapy commands, captures device and therapy data, and synchronizes information to the cloud. This is a hands-on individual-contributor architecture role. The architect sets long-term technical direction, establishes standards for iOS engineers, mentors senior engineers, and makes critical design decisions. The role partners with firmware, cloud, cybersecurity, quality, human factors, and regulatory teams to support a safe, reliable, maintainable, and FDA-compliant medical device. It is hybrid, with 1–2 days per week in the office.

Requirements

Bachelor’s degree in Computer Science, Electrical Engineering, or Computer Engineering.
At least 10 years of professional software engineering experience, including substantial recent experience architecting and shipping production iOS apps.
Deep experience with Swift and Apple platform APIs, including application lifecycle, background execution, networking, and local storage.
Demonstrated iOS Bluetooth Low Energy experience using Core Bluetooth, including connection management, pairing, and reliable command and notification handling.
Experience defining architecture for a connected system in which a mobile app controls or acts as a gateway for a physical device and cloud backend.
Working knowledge of HIPAA as it applies to collecting, storing, and transmitting protected health information from a mobile medical app.
Experience in a regulated quality system, such as medical device, aerospace, or another design-control environment, including requirements traceability and verification.
Ability to write and defend architecture decisions that balance safety, security, reliability, and delivery speed.
Clear written and verbal communication with engineers and quality, regulatory, and clinical partners.

Nice To Haves

Experience with insulin delivery, CGM, or other Class II or Class III connected medical devices.
Working knowledge of IEC 62304, ISO 14971, IEC 62366, FDA design controls, and FDA premarket cybersecurity guidance.
Mobile medical software security architecture experience, including secure storage, certificate pinning, authenticated cloud APIs, and BLE security modes.
Experience with Android apps to keep iOS and Android controllers aligned across capabilities.
Flutter or Kotlin Multiplatform experience limited to shared non-UI logic, with the therapy user interface remaining native iOS.
Experience with offline-first synchronization, conflict handling, and auditability of device data uploaded to the cloud.
Production-scale experience with SwiftUI and UIKit, modularization, and dependency boundaries that isolate safety-critical paths.
Experience contributing technical content to regulatory submissions or design history files.
Graduate degree in Computer Science, Electrical Engineering, or Computer Engineering.
Experience mentoring senior and principal-level engineers and setting engineering standards across teams as an individual contributor.

Responsibilities

Define and evolve iOS architecture for pump control, CGM and pump data capture, local persistence, and cloud upload, including behavior during connection loss, background execution, and app lifecycle events.
Own the app’s BLE strategy, including connection models, pairing and bonding, reconnection, reliable commands and data handling, and coordination with pump firmware constraints.
Set the iOS platform’s technical vision and turn it into roadmaps, architecture decision records, interface contracts, and implementation standards.
Design for a regulated medical device, including traceable requirements, risk controls, verification and validation, and FDA design-control software lifecycle practices.
Establish security and privacy architecture for therapy commands and protected health information in transit and at rest, aligned with HIPAA, FDA cybersecurity expectations, and healthcare privacy obligations.
Define data integrity rules for glucose, insulin delivery, and device-state data from phone capture through cloud upload and reconciliation.
Review designs and critical code paths, and mentor senior engineers to maintain architectural intent through implementation.
Partner with firmware, cloud, quality, human factors, and regulatory teams on interface contracts, hazard mitigations, and technical evidence for submissions.
Evaluate cross-platform options such as Flutter or Kotlin Multiplatform for shared non-UI logic while keeping the therapy user interface native iOS.
Identify and mitigate technical risks involving connectivity, battery life, latency, data loss, and upgrade compatibility.
