Senior Website Developer - Replatform Initiative

Our client is undertaking a major replatforming initiative from Sitecore XP to Sitecore XM Cloud and is seeking a Senior Developer to play a key technical role in designing, building, and optimizing a modern, headless digital experience platform. This role will serve as a hands-on technical leader and subject matter expert, driving best practices across frontend architecture, cloud-native development, and the greenfield implementations. Position is based in Buckhead and is 3 days per week onsite. This is a full-time role.

Key Responsibilities

• Design, develop, and maintain enterprise-scale, cloud-native web solutions supporting the migration from Sitecore XP to Sitecore XM Cloud.
• Serve as a technical subject matter expert across the full software development lifecycle, including architecture, development, testing, deployment, and production support.
• Build and integrate headless frontend experiences using Next.js, React, TypeScript, and GraphQL, leveraging Sitecore JSS and XM Cloud.
• Collaborate closely with architects, product owners, and cross-functional teams to deliver scalable, well-integrated solutions aligned with business and platform goals.
• Define and implement modern rendering strategies (SSG, SSR, ISR) to optimize performance, SEO, and Google PageSpeed scores.
• Design and optimize personalization and real-time content experiences using Sitecore CDP/Personalize and Sitecore Search.
• Own and optimize CI/CD pipelines and deployment workflows, including Vercel deployments, environment configuration, and performance optimization.
• Ensure adherence to application architecture standards, secure coding practices, and cloud observability (monitoring, logging, and alerting).
• Perform code reviews, mentor developers, and promote knowledge sharing and technical excellence across the development team.
• Troubleshoot and resolve highly complex production issues, serving as an escalation point and providing third-level application support (including on-call rotation).
• Evaluate and recommend tools, frameworks, and vendor solutions to support ongoing platform evolution.
• Address security scan findings and ensure compliance with security and quality standards.

Required Qualifications

• Sitecore XM Cloud or similar product.
• 2+ years of hands-on, production experience with Sitecore XM Cloud (XM Cloud experience required; legacy XP/XM alone is not sufficient).

Skills and Experience

• Frontend & Headless Development: Strong expertise in Next.js, React.js, TypeScript, and GraphQL.
• Sitecore Headless Architecture: Advanced knowledge of Sitecore JSS, headless CMS patterns, and modern web architecture preferred.
• Cloud & DevOps: Experience with Vercel, CI/CD pipelines, and tools such as Azure DevOps or GitHub Actions.
• Engineering Excellence: Strong understanding of cloud-native principles, performance optimization, and observability.
• Collaboration & Problem Solving: Ability to work independently on complex initiatives while partnering effectively across teams.
