Senior Full-Stack Software Developer

Job Description We are seeking a highly skilled Senior Full-Stack Software Developer to lead the development, stabilization, and enhancement of the SHERQ365 application. This role requires managing a complex project involving an AI-generated codebase, with responsibilities encompassing code assessment, backend API development, authentication, database infrastructure, notifications, offline synchronization, and testing. The candidate must deliver production-ready features across modules, mitigate technical debt and risks, and propose efficient compromises to align with quality and timeline objectives. The project involves refining an AI-generated frontend (built with v0.dev), characterized by inconsistent patterns, absent documentation, incomplete error handling, and hardcoded mock data, into a robust enterprise system with integrated backend functionalities. Requirements Required Skills and Experience Bachelor's or Master's in Computer Science or related field. Certifications: Azure Developer Associate, AWS Certified Developer, or Scrum Master preferred. Portfolio/references for authentication, offline sync, and API projects. Technical Expertise : Full-stack proficiency in JavaScript/TypeScript (React/Node.js/Express). Database management with PostgreSQL/Neon. Authentication: OAuth, Azure AD, MFA, RBAC. RESTful API design for complex workflows. Notifications: Resend, Twilio, cron scheduling. Offline tech: IndexedDB, Service Workers, PWA, sync tools (e.g., PowerSync). Git, CI/CD, testing (Jest/Cypress), security (OWASP). Project Management : Experience with AI/legacy codebases, time estimation, and risk assessment. Soft Skills : Analytical trade-off evaluation, communication, independent work. Experience Level : 7-10 years in enterprise software, preferably SHERQ or similar domains. KPI’s KPI Description Target Measurement Method Project Completion Timeline Adherence to the overall project schedule, ensuring delivery within the estimated 725 hours. Complete project within 725 hours or less, with no more than 10% overrun. Track total hours logged against the compromised estimate using time-tracking tools (e.g., Jira or Toggl). Module Delivery Efficiency Successful completion of individual modules (e.g., Authentication, Incident Management) within allocated hours. Achieve at least 90% of modules on or under budgeted hours (e.g., Authentication: 60 hours). Compare actual hours spent per module against proposed hours via project management reports. Code Quality and Stabilization Reduction of technical debt and standardization of the AI-generated codebase. Attain 80% code coverage in tests and resolve at least 90% of identified issues from initial audit. Use code analysis tools (e.g., SonarQube) for coverage metrics and audit logs for issue resolution tracking. Feature Implementation Accuracy Delivery of core features, including compromises (e.g., defer Google OAuth, email-only notifications). Implement 100% of mission-critical features (e.g., offline sync) and at least 95% of all specified requirements. Conduct milestone reviews and user acceptance testing (UAT) to verify feature completeness against the document's scope. Risk Mitigation Effectiveness Management of high-risk areas (e.g., Authentication, Offline Sync) to prevent production issues. Reduce high-risk items to medium or low by project end, with zero critical security vulnerabilities. Perform risk assessments at key milestones using tools like OWASP checklists and track via a risk register. Testing and Security Compliance Thorough testing and hardening to ensure application reliability and security. Achieve 95% pass rate in unit/integration tests and pass all security audits. Monitor test results from frameworks (e.g., Jest, Cypress) and security scan reports (e.g., from Snyk or similar). Documentation and Reporting Production of necessary documentation and timely progress reports. Deliver bi-weekly reports and lightweight docs covering 100% of key modules. Review submission logs and completeness checklists in project management software. Overall Budget Adherence Alignment with financial constraints based on hourly rate. Stay within R616,250 budget equivalent. Calculate total expenditure from hours and rate, reviewed monthly. Benefits Compensation and Benefits Competitive salary. Flexible remote/hybrid options in Johannesburg, Gauteng. Professional development and future project opportunities.
