Job summary

Hammerjack Pty Ltd in the Philippines is seeking a Software Engineer to join our Information Systems team. You'll work across full-stack development, systems integration, and internal tooling, taking ownership of features end-to-end and contributing to technical decisions along the way.

This role suits an engineer with a few years of hands-on experience who can work independently, occasionally guide juniors, and apply AI/LLM tools to real engineering challenges—from AI-assisted development

Qualifications

• 2–4 years of professional software development experience.
• Proficiency in at least one back-end language (PHP/Laravel or similar) and one front-end framework (React).
• Experience using AI coding tools (Cursor, ChatGPT, Claude, Copilot) for coding or debugging.
• Understanding of REST APIs and third-party integrations.

Responsibilities

• Build and maintain features across front-end (React) and back-end (PHP/Laravel) with minimal supervision.
• Contribute to the design of internal tools, dashboards, and automation workflows.
• Implement and maintain APIs and third-party integrations (billing systems, ticketing, messaging, identity verification, etc.).
• Write clean, testable, well-documented code and actively participate in code reviews.
• Use AI coding assistants (Cursor, Claude, Copilot) effectively as part of your daily workflow, and help share best practices with the team.
• Build AI-powered features — e.g., calling LLM APIs for text processing, summarization, or automation — with some autonomy over implementation approach.
• Debug and troubleshoot moderately complex issues across the stack, including with the help of AI tools where appropriate.
• Provide guidance and code review feedback to junior engineers.

Job description

Job Summary:

We're looking for a Software Engineer to join our Information Systems team. You'll work across full-stack development, systems integration, and internal tooling, taking ownership of features end-to-end and contributing to technical decisions along the way. This role suits an engineer with a few years of hands-on experience who can work independently, occasionally guide junior teammates, and has practical experience applying AI/LLM tools to real engineering problems — from AI-assisted development workflows to building features that call AI APIs.

Responsibilities:

• Build and maintain features across front-end (React) and back-end (PHP/Laravel or similar) applications with minimal supervision
• Contribute to the design of internal tools, dashboards, and automation workflows
• Implement and maintain APIs and third-party integrations (billing systems, ticketing, messaging, identity verification, etc.)
• Write clean, testable, well-documented code and actively participate in code reviews
• Use AI coding assistants (e.g., Cursor, Claude, Copilot) effectively as part of your daily workflow, and help share best practices with the team
• Build AI-powered features — e.g., calling LLM APIs for text processing, summarization, or automation — with some autonomy over implementation approach
• Debug and troubleshoot moderately complex issues across the stack, including with the help of AI tools where appropriate
• Provide guidance and code review feedback to junior engineers

Requirements:

• 2–4 years of professional software development experience
• Solid, hands-on experience in at least one back-end language (PHP with Laravel, JavaScript/Node, or similar) and one front-end framework (React preferred)
• Good understanding of REST APIs and experience integrating third-party systems
• Practical experience using AI coding tools (Cursor, ChatGPT, Claude, Copilot, etc.) for coding, debugging, or documentation
• Working understanding of how LLMs/AI APIs work (prompts, tokens, basic tool use) and some experience integrating them into features
• Comfortable with Git and standard version control workflows, including branching and code review processes
• Good problem-solving skills and ability to work independently on well-scoped tasks
• Strong communication skills and ability to collaborate across product, QA, and other engineering teams

Nice to Have:

• Experience working in AI-assisted IDEs like Cursor for codebase navigation and refactoring
• Exposure to workflow automation tools (e.g., n8n, Zapier)
• Some experience mentoring or supporting junior engineers
• Experience shipping AI-powered features (OpenAI, Anthropic, or similar APIs) in a production environment

This is a fully onsite role with no work-from-home or hybrid work arrangement, ideal for candidates who enjoy a collaborative, dynamic, and hands-on work environment.
