Senior Software Engineer

Requirements:

• 5+ years of full-stack development experience, with engineering team leadership preferred.
• Proficiency in languages like PHP, Python, or Node.js, with strong hands-on experience in enterprise frameworks like Symfony or FastAPI.
• Proficiency in MySQL (or similar relational database), including schema design, query optimization and data integrity.
• Hands-on experience developing and delivering modular, scalable frontend applications with Vue 3 and TypeScript.
• Hands-on experience implementing Elasticsearch for search and filtering features.
• Hands-on experience with cloud services (AWS preferred) and container technologies like Docker, including building, deploying, maintaining, and troubleshooting production applications in production environments.
• Familiarity with AI coding assistants (e.g., Claude Code, Codex, GitHub Copilot, etc) for code generation and problem-solving.
• End-to-End Quality: Take full ownership of code quality by implementing robust unit, integration, and API automated tests to verify changes before release.
• High Autonomy: Navigate ambiguity by proactively clarifying requirements, proposing scalable technical solutions, and driving delivery with cross-functional stakeholders.
• Communication & Mentorship: Mentor junior peers and explain technical concepts to non-technical business partners in excellent English. Cantonese is a plus.

Responsibilities:

• Own the end-to-end delivery of full-stack features, from requirements clarification and technical design through implementation, testing, deployment, and post-release support.
• Work directly with product, operations, and app engineering teams to translate business needs into practical technical solutions, communicate trade-offs, and proactively resolve delivery blockers.
• Develop and extend Sylius/Symfony modules with clear domain models and maintainable business logic. Design and optimize database schemas and queries to support application performance and data integrity.
• Build and maintain reusable Vue 3 and TypeScript components, and evolve the frontend architecture to deliver consistent, responsive user experiences.
• Design, implement, and maintain APIs and integrations supporting native Android/iOS apps, e-commerce operations systems such as Odoo, and internal services, ensuring reliable data exchange and backward compatibility.
• Improve search and product discovery with Elasticsearch through relevance tuning, query optimization, and reliable indexing and data synchronization workflows.
• Take ownership of code quality through automated unit, integration, and API tests, covering critical business workflows, edge cases, and integration contracts before release.
• Deploy and support applications in cloud and containerized environments, monitor changes after release, and troubleshoot production issues. Identify root causes and implement improvements that reduce recurring incidents.
• Guide technical decisions, conduct constructive code reviews, and mentor junior engineers. Proactively improve engineering practices and address technical debt to keep the codebase maintainable as the business grows.

Nice to have:

• Experience working with ERP platforms (especially e-commerce operations workflows and understanding finance/accounting requirements).
• Experience working within a retail or e-commerce business environment (domain knowledge of inventory, promotions, logistics, etc.).
• Mobile-facing API design experience (versioning, backward compatibility, performance).

Additional information:

• The team is lean: successful candidates are highly self-directed.
• End-to-end ownership: you're accountable for outcomes after release.
• High autonomy and proactivity: you move work forward with minimal hand-holding.
• Stakeholder engagement: you can work directly with product, operations, and app teams.
• Quality first: clean code, pragmatic architecture, and reliable tests.
