Application Software Developer Jobs in Minnesota

The Principal Mobile & Application Software Engineer is a hands-on technical leader responsible for the design, development, and delivery of the top-level software platform for next-generation medical imaging devices. This includes mobile applications (iOS/Android), system-level software integration, user interface development, and overall application architecture.

This role owns the transformation of processed imaging and sensor data into intuitive, reliable, and clinically actionable user experiences. Working in close partnership with Vision Software and Vision Systems Engineering, this position integrates complex multimodal data (RGB, thermal, fluorescence, NIRS, 3D) into a cohesive application layer.

In addition to development, this role is responsible for software process execution (JIRA/Agile), documentation, and software verification and validation within a regulated medical device environment.

ROLES AND RESPONSIBILITIES

Application Architecture & Technical Leadership:

Own the architecture and implementation of the top-level software platform, including mobile applications and system integration layers.

Define application-level software architecture, including:

- Data flow from embedded device → mobile application → cloud/storage.

- Real-time visualization and interaction models.

- System state management and device control interfaces.

Establish performance targets for application responsiveness, reliability, and usability.

Serve as the primary technical lead for application-layer software across the program.

Mobile Application Development (iOS & Android):

Lead development of cross-platform or native mobile applications for medical imaging systems.

Design and implement:

- Real-time visualization of multimodal imaging data.

- UI/UX for clinical workflows (capture, review, annotation, export).

- Device connectivity (Wi-Fi, BLE, USB).

Optimize performance on mobile SoCs (CPU/GPU/NPU) for real-time interaction.

Ensure consistent behavior and performance across iOS and Android platforms.

Collaborate with UX/UI designers and clinical stakeholders to deliver intuitive, high-value interfaces.

Support multispectral, NIR, fluorescence, thermal, or depth-based imaging pipelines as required by the product roadmap.

System Integration (Device ↔ App ↔ Cloud):

Define and implement communication between embedded imaging hardware and mobile applications:

- Streaming, buffering, and synchronization of image data.

- Command/control interfaces for device operation (LEDs, capture modes, sensors).

Architect data handling strategies:

- On-device processing vs mobile vs cloud partitioning.

- Compression, storage, and transfer of large imaging datasets.

Support integration with backend/cloud systems and EHR workflows where applicable.

Software Process, Program Execution & JIRA Ownership:

Own software execution framework using Agile/Scrum methodologies.

Build and manage:

- JIRA epics, stories, and sprint plans.

- Cross-functional dependencies (vision SW, firmware, hardware).

Translate system and product requirements into clear, actionable software work packages.

Drive execution discipline across the software team (planning, tracking, delivery).

Identify risks, bottlenecks, and mitigation strategies early.

Verification, Validation & Regulatory Compliance:

Define and execute software verification and validation strategies for the application layer.

Develop test frameworks for:

- Functional validation.

- UI/UX validation.

- System integration testing.

Ensure compliance with medical device standards including:

- IEC 62304

- ISO 13485

Support Design History File (DHF) development, including:

- Software requirements.

- Architecture documentation.

- Traceability

- Verification evidence.

Participate in risk management and usability engineering activities issues.

Cross-Functional Collaboration:

Partner closely with: Vision Software Engineers (algorithms, image processing), Vision Systems Engineers (hardware, optics, sensors), Firmware and embedded teams.

Translate complex technical outputs into usable application features.

Participate in system-level tradeoffs:

- Latency vs fidelity.

- On-device vs. mobile compute.

- UX vs technical constraints.

Interface with external partners, contractors, and software vendors.

Documentation, Productization and Compliance:

Create and maintain clear, structured documentation for:

- Application architecture.

- APIs and interfaces.

- Data models and workflows.

Support regulatory submissions and audits with well-organized documentation.

Contribute to product readiness including:

- Release management.

- Field support tools.

- Post-market updates.

Stakeholder Engagement:

Support technical discussions with suppliers, manufacturing partners, and internal stakeholders.

Assist with product launches, field issue investigations, and post-market support as needed.

Translate clinical, system, and business requirements into actionable imaging engineering specifications.
