Part Time Full Stack Developer

Company Description

nuBorn Medical is developing an innovative smart bottle system designed to provide real-time feeding insights for clinicians and parents. Our goal is to support optimal care and nutrition for newborns, from the NICU to the comfort of their homes. Through cutting-edge technology, we aim to empower caregivers with accurate and actionable data to enhance feeding experiences for infants. By addressing critical challenges in newborn care, we are committed to making a positive impact on families and healthcare providers.

Role Description

We are seeking an experienced Contract Full Stack Developer to design and build a secure, HIPAA-compliant mobile and cloud application. The initial focus will be an iOS application that communicates with a Bluetooth-enabled IoT medical device, securely harvesting device data and transmitting it to an AWS-based API and storage stack for processing and persistence.

The IoT device itself is not network-enabled and will rely entirely on the mobile application as a secure data relay. The architecture is expected to evolve over time toward a full JavaScript-based middleware application layer supporting advanced business logic, analytics, and UI-driven calculations.

Key Responsibilities

AWS Backend Infrastructure and iOS Mobile Application Development

Design and build an iOS application to:

* Communicate with Bluetooth (BLE) enabled IoT devices

* Securely collect and validate device data

* Transmit data to AWS via secured API endpoints

Ensure mobile application and backend infrastructure adheres to HIPAA compliance standards, including:

* Secure data transmission

* Encryption at rest and in transit

* Secure device handling and authentication

* Design the mobile architecture to be future-compatible with Android (e.g., shared logic, cross-platform considerations)

* Backend & Cloud Development

Develop and maintain AWS-based API infrastructure, initially leveraging:

* AWS Lambda for API routes

* API Gateway for secure access

* SQL database (e.g., RDS or Aurora) for structured data

* Amazon S3 for object and raw data storage

* Implement secure read/write operations from mobile clients to cloud services

* Ensure AWS infrastructure follows HIPAA-aligned security best practices

Architecture & Evolution

Contribute to the design of a future full-stack JavaScript middleware layer that will:

Perform calculations, transformations, and business logic

Support application-level functions consumed by the mobile app

Collaborate on architectural decisions that support scalability, compliance, and long-term maintainability

Required Qualifications

* U.S. Citizen (required due to data sensitivity and compliance requirements)

* This will be a W2 role, no 1099, no agencies or C2C

* Proven experience as a Full Stack Developer with mobile and cloud components

* Strong experience developing iOS applications (Swift preferred)

* Hands-on experience with Bluetooth / BLE communication in mobile apps

Solid knowledge of AWS infrastructure, including:

* AWS Lambda

* API Gateway

* SQL databases (RDS/Aurora)

* Amazon S3

* Experience building secure, HIPAA-compliant applications

* Understanding of secure API design, authentication, and encryption practices

Preferred / Nice-to-Have Skills

* Android development experience or cross-platform frameworks (e.g., React Native, Flutter)

* JavaScript / TypeScript experience for future middleware layer development

* Experience with IoT data ingestion workflows

* Familiarity with healthcare or regulated environments

* Experience designing scalable, event-driven architectures on AWS

Deliverables & Success Criteria

* Secure, production-ready iOS application communicating with a Bluetooth IoT device

* HIPAA-compliant data flow from device → mobile app → AWS

* Clean, well-documented cloud APIs and data storage patterns

* Architecture ready for future Android support and middleware expansion
