- Design, develop, test, and maintain robust, scalable, secure, and production-ready applications using modern full-stack technologies, including React, TypeScript, .NET 8, and C#.
- Take end-to-end ownership of assigned features and code repositories, from technical design and implementation through deployment, monitoring, and production support.
- Leverage AI-powered development tools, including GitHub Copilot and coding agents, to accelerate code exploration, implementation, refactoring, debugging, automated testing, and documentation while maintaining rigorous quality standards.
- Collaborate with senior engineers to establish secure, repeatable, and effective AI-assisted development practices, reusable workflows, and appropriate validation and review processes.
- Participate in code reviews, establish development standards, and improve engineering efficiency through high-quality technical feedback and streamlined pull-request workflows.
- Continuously improve application architecture, repository health, automated test coverage, code quality, and security by addressing technical debt, vulnerabilities, and SonarQube findings.
- Work closely with product, architecture, quality assurance, DevOps, platform, and data teams to deliver innovative solutions within an agile development environment.
- Contribute to incident investigations, root-cause analysis, application observability, and sustainable corrective actions to ensure reliable production systems.
- Share technical knowledge through demonstrations, pair programming, mentoring, and documentation to encourage the adoption of AI-assisted engineering practices across the team.
- Drive measurable improvements in software delivery, including shorter development cycles, fewer recurring defects, stronger security, and greater engineering efficiency without compromising production quality.

- Has 7+ years of professional software development experience, including significant ownership of production systems and strong full-stack expertise in React, TypeScript, .NET 8, and C#.
- Has hands-on experience with AI-assisted development tools, such as GitHub Copilot and coding agents, across implementation, refactoring, testing, debugging, and documentation, including prompt and context management.
- Demonstrates strong technical judgment, particularly in evaluating AI-generated code, identifying security risks, and ensuring appropriate validation and review practices.
- Has solid knowledge of modern software architecture and engineering practices, including API design (REST, GraphQL), distributed systems, BFF, microservices, automated testing, CI/CD, observability, secure coding, and cloud-native development.
- Is proficient with modern development technologies and tools, including PostgreSQL, GitHub, SonarQube, Playwright, performance testing, and Google Cloud Platform (Cloud Run, Pub/Sub, Cloud SQL).
- Understands software quality and security best practices, including repository ownership, pull-request workflows, vulnerability remediation, Okta SSO, least-privilege access, secrets management, auditability, and secure SDLC.
- Combines strong problem-solving skills with autonomy and collaboration, demonstrating sound technical decision-making, clear communication, accountability, and a willingness to share knowledge and support teammates.
