Job responsibilities

• Executes software solutions, design, development, and technical troubleshooting with ability to think beyond routine or conventional approaches to build solutions or break down technical problems
• Creates secure and high-quality production code and maintains algorithms that run synchronously with appropriate systems
• Produces architecture and design artifacts for complex applications while being accountable for ensuring design constraints are met by software code development
• Gathers, analyzes, synthesizes, and develops visualizations and reporting from large, diverse data sets in service of continuous improvement of software applications and systems
• Proactively identifies hidden problems and patterns in data and uses these insights to drive improvements to coding hygiene and system architecture
• Contributes to software engineering communities of practice and events that explore new and emerging technologies
• Adds to team culture of diversity, opportunity, inclusion, and respect

• Leverages enterprise-authorized AI coding assist tools within the work environment to improve code quality, delivery speed, and productivity across complex deliverables (e.g., code generation/refactoring, unit test creation, documentation), while validating outputs through peer review, automated testing, and secure coding standards; contributes learnings and reusable patterns to improve broader team effectiveness

• Applies knowledge of tools within the Software Development Life Cycle toolchain, including enterprise-authorized AI-assisted development and automation capabilities, to improve the value realized by automation

Required qualifications, capabilities, and skills

• Formal training or certification on software engineering concepts and 3+ years applied experience

• Hands-on practical experience in system design, application development, testing, and operational stability

• Experience with a strong focus on front-end engineering. Strong proficiency in React (building dynamic UIs), JSX, HTML5, and CSS (responsive layouts)

• Hands-on experience with modern JavaScript frameworks/libraries (e.g., React, Angular) and core web technologies (JavaScript, HTML5, CSS)
• Experience with frontend state management (e.g., Redux)
• Hands-on experience deploying and operating front-end applications on AWS using S3 (static hosting) and CloudFront (CDN), including cache invalidation and release/versioning strategies
• Strong understanding of securing static web hosting on AWS: S3 Block Public Access, CloudFront Origin Access (OAC/OAI as applicable), least-privilege IAM, and enforcing HTTPS/TLS via CloudFront
• Knowledge of edge/web protection concepts including TLS/HTTPS, AWS WAF, and secure HTTP headers (e.g., CSP, frame-ancestors, HSTS).

Proven experience building CI/CD for S3/CloudFront deployments (build → artifact → upload to S3 → CloudFront invalidation), including environment promotion, rollbacks, and post-deploy smoke checks

• Hands-on experience using enterprise-authorized AI-assisted software development tools within the work environment (e.g., for coding, test creation, troubleshooting, or documentation) with demonstrated ability to critically evaluate, validate, and refine AI-generated outputs for correctness, performance, and security
• Understanding of responsible AI use in engineering workflows, including data sensitivity considerations, secure handling of inputs/outputs, and adherence to resiliency and security expectations; ability to guide peers on safe and effective usage within team practices

Preferred qualifications, capabilities, and skills

• Familiarity with modern front-end technologies
• Exposure to cloud technologies
