Cloud-Native Deployment: Advance your containerization expertise by working directly with Microsoft Azure and Azure Kubernetes Service (AKS).
Interoperability Domain Depth: Deepen your knowledge of digital health standards by implementing cutting-edge healthcare data exchange protocols.
Inclusive Engineering Focus: Refine your user-interface capabilities by designing web layers with an explicit focus on universal accessibility requirements.
Responsibilities
Component Architecture Design: Prepare and present detailed technical analyses and structural models to support software component designs for the project team.
Full-Stack Software Engineering: Analyze, design, code, test, debug, and document complex, multi-tier web applications using modern front-end and back-end languages.
Cloud & Containerization Management: Configure, manage, and deploy containerized application components within Microsoft Azure and Kubernetes environments.
Interface & Accessibility Development: Develop responsive, user-friendly graphical interfaces with a dedicated focus on meeting digital accessibility compliance mandates.
API & Data Exchange Integration: Design and construct high-performance RESTful web services that adhere strictly to modern healthcare data exchange protocols and reference frameworks.
Database & Storage Optimization: Create, optimize, and maintain complex relational and document-oriented schemas using modern database systems.
Agile Framework Collaboration: Participate actively in project focus groups, joint application design (JAD) sessions, daily scrums, and technical alignment meetings with infrastructure providers.
Critical Production Support: Provide ongoing technical investigations, environment troubleshooting, and software corrections for production-tier application systems.
Proactive Risk Mitigation: Identify, trace, and communicate systemic code issues, infrastructure requirements, and project risks to delivery management before they impact deployment schedules.
Protocol & Lifecycle Assurance: Review network, software, and hardware communication requirements to ensure all integration pieces conform to established technical templates and protocols.
Qualifications
Core Technical & Full-Stack Requirements
Multi-Engine Programming Fluency: Deep, hands-on software development experience writing code across a diverse technology stack including Java, JavaScript (ES6+), TypeScript, and Node.js.
Advanced Framework Expertise: Proven capability building microservices and web apps using Spring Framework, Quarkus, Angular 9+, and Angular Material.
Cloud Infrastructure Depth: Practical experience configuring and deploying applications inside cloud environments, specifically Microsoft Azure and Azure Kubernetes Service (AKS), or related alternatives (OpenShift, Docker, AWS).
Healthcare Interoperability Knowledge: Foundational understanding of digital healthcare data exchange standards, with a specific focus on Fast Healthcare Interoperability Resources (FHIR). (Familiarity with HAPI FHIR or SmileCDR platforms is considered a strong asset).
Database & Protocol Savvy: Solid experience managing data tiers utilizing PostgreSQL relational databases alongside an understanding of standard communication protocols (HTTP, HTTPS, SFTP, TCP/IP).
Business Rules Configuration: Structural familiarity with workflow or rules-engine automation tools such as Drools is an asset.
Engineering Methodologies & Software Design
Modeling & Specifications: Strong background in technical analysis, object-oriented software engineering, and utilizing UML diagramming to model software solutions.
Accessibility Compliance: Demonstrated experience designing user interfaces that comply with strict digital web accessibility standards (AODA guidelines).
Document Assembly Asset: Practical experience programmatically assembling dynamic PDF and Word documents is considered a beneficial asset.
Professional Leadership & Soft Skills
Risk Management Acumen: Exceptional capability to proactively profile, isolate, and mitigate development blockers or architecture constraints before they impact delivery timelines.
Consultative Articulation: Excellent verbal, written, and presentation communication skills, with polished ease when explaining technical system trade-offs to cross-functional teams.
Collaborative Execution: A reliable, detail-oriented team player with strong negotiation and interpersonal skills who maintains a proven track record for meeting strict project deadlines.
