• Work closely with delivery leads and product owners to ensure solutions meet business needs
• Contribute to strategic planning around tooling, technology choices, and platform direction
• Perform technical reviews and provide input on system design, integration, and performance
• Advocate for engineering best practices, clean code, testing, observability, and performance
• Stay up to date with emerging technologies and propose relevant improvements
  

Requirements

• 8+ years of software engineering experience, with a strong background in full-stack or frontend/backend systems
• Experience with modern frontend ecosystems (React, Vue, etc.) and/or backend stacks (Node.js, Java, Python)
• Exposure to cloud platforms like AWS, GCP, or Azure
• Familiarity with DevOps practices, CI/CD pipelines, and performance monitoring tools
• Experience leading large technical projects and mentoring other engineers
• Previous experience in eCommerce, retail, or large-scale customer-facing platforms

• Excellent problem-solving and analytical skills; able to break down complex challenges
• A strong communicator who can translate technical detail into clear plans and decisions
• Experience working in collaborative product and delivery teams
