Full Stack Engineer (C++)

Zipdev is helping its client in building and evolving software that supports modern clinical and operational workflows. The product surface includes Windows desktop applications and connected services, with a strong emphasis on reliability, maintainability, and customer experience. As a Full‑Stack Engineer, you will deliver end-to-end capabilities across the Windows client, service/business logic layers, and the database. Your primary stack will include C++ (MFC) for desktop UI and application behavior, C# for services and shared business logic, and MS SQL for data persistence. **Key Responsibilities** **Full‑Stack Delivery (End‑to‑End)** * Design, build, and maintain features across the full stack (C++/MFC desktop → C# services/business logic → MS SQL). * Own features from requirements through implementation, test readiness, release, and production support. * Collaborate with QA and product partners to refine acceptance criteria, validate behavior, and ensure release readiness in an Agile cadence. * Participate in AI-augmented development workflows, reviewing and validating AI-generated code against acceptance criteria. * Follow Git best practices: feature branches, pull requests for all changes, and clear commit hygiene; proactively update documentation when behavior or architecture changes. **Desktop (C++ / MFC)** * Design, build, and maintain Windows workflows using C++ and MFC. * Debug and remediate defects across UI, threading, memory/resource management, and performance hotspots. * Modernize and refactor legacy areas to improve maintainability, testability, and stability while preserving user workflows. * Implement defensive coding patterns and robust error handling suitable for regulated environments. **Services & Business Logic (C#)** * Develop and maintain C# components and service layers that support desktop workflows and integrations. * Design and consume APIs or internal contracts as needed to connect client and service components. * Implement secure authentication/authorization patterns appropriate for enterprise and regulated contexts. * Create and maintain automated checks and diagnostics to support supportability and observability. **Data Layer (MS SQL)** * Design and evolve MS SQL schemas with emphasis on clarity, performance, and data integrity. * Write and optimize queries, stored procedures, and migration scripts where appropriate. * Collaborate with QA and Engineering to validate data correctness and enable reliable test data setup. * Contribute to troubleshooting production issues through data analysis and root cause investigation. **Quality, Testing, and Agile Execution** * Demonstrate knowledge of QA processes in an Agile environment, including acceptance criteria, defect triage, regression awareness, and collaboration with QA roles. * Contribute to test strategy (unit/integration as appropriate), and ensure features meet functional, security, and reliability expectations. * Maintain a disciplined approach to compliance and secure engineering practices. **Core Technical Skills** * Strong experience developing Windows desktop applications using C++ and MFC. * Strong experience developing with C# (services, libraries, or application layers). * Solid relational database skills with MS SQL (schema design, query awareness, performance basics). * Proven ability to debug complex issues across layers (UI ↔ business logic ↔ database) and drive fixes to completion. * Familiarity with Git-based workflows (pull requests, code reviews) and maintaining engineering documentation. **AI‑Augmented Development (Required)** * Hands-on experience using AI coding assistants as part of daily development, with a clear understanding of the Human → AI → Human review loop and human accountability. * Ability to maintain supporting documentation such as READMEs, architecture notes, and engineering guidelines. **HIPAA & Compliance Awareness (Required)** * Strong understanding that Protected Health Information (PHI) must never appear in code, logs, tests, commits, or error messages; comfort working with synthetic/mock data. * Awareness of secure coding practices (no hardcoded credentials, least-privilege access patterns, safe error handling). **Must be located in LATAM and have high English proficiency (C1+).** **Preferred / Nice‑to‑Have Qualifications** * Healthcare or dental domain experience. * Experience maintaining and modernizing mature/legacy Windows desktop codebases. * Experience with performance profiling and memory diagnostics in native Windows applications. * Experience contributing to a product that integrates desktop and cloud/hosted services. * Work remotely Monday - Friday, 40 hours a week (no weekends) * Health Care Reimbursement * Active Lifestyle Reimbursement * Quarterly Home Office Reimbursement * Did we mention it's REMOTE?!!
