Software Engineer

Unleash Your Talents with Us!

Hi there, our future Software Engineer! Happy to see YOU here.

Here at Integrated OS, you'll be part of a team of passionate individuals who are committed to delivering exceptional offshoring services. Bringing in an array of skills and talents from different areas of business from Finance, Human Resources, Information Technology, Customer Service, and Marketing to Sales and Operations.

From humble beginnings, we have built our company from our first team member onwards. Initially, we were lending support to an Australian print manufacturer - The Lamson Group.

Since then, we have continued to uphold our core values and culture and developed a deeper understanding of how people need help to succeed in their goals. And YOU might be a part of this amazing growth as our team keeps growing above all expectations!

What you'll do:

As a Software Engineer, you will work across both legacy system support and the development of a modern platform rebuild. You will play a key role in ensuring business-critical systems remain stable while contributing to the future of the company's technology.

You will investigate and resolve issues, build new features, and collaborate with cross-functional teams to deliver scalable, high-quality solutions. This role requires someone who is comfortable working with both legacy codebases and modern frameworks, with a strong focus on continuous improvement and clean, maintainable code.

Key responsibilities for this role include:

Legacy CRM Maintenance & Support

• Investigate and resolve bugs, data issues, and production incidents across the existing CRM.
• Deliver enhancements and small feature requests in the legacy CodeIgniter/PHP codebase.
• Write and optimize MySQL queries while protecting data integrity and performance.
• Maintain integrations with third-party services (HubSpot, Microsoft Graph, AWS, Stripe, DocuSign).

New CRM Development

• Build and maintain modules and features for the Laravel-based CRM rebuild.
• Design, implement and document RESTful APIs and integrations.
• Create and maintain database migrations, seeders, models and application logic.
• Implement responsive frontend components using the project's current JavaScript libraries and frameworks.
• Contribute to technical design discussions and raise risks or alternative approaches early.

UI/UX, Product Thinking & Continuous Improvement

• Consider the user's goals and workflow when implementing screens and features.
• Suggest practical improvements to navigation, layout, forms, data presentation, accessibility, consistency and usability.
• Help translate business requirements into clear user flows and implementation options; use sketches, wireframes or prototypes where helpful.
• Balance visual polish and usability with technical constraints, delivery priorities and existing functionality.

AI-Assisted Development & Engineering Quality

• Support deployment processes and Docker-based development environments.
• Verify AI-generated suggestions rather than accepting them blindly; understand the code being submitted and test it appropriately.
• Do not expose credentials, confidential business data or production information to unapproved AI tools.
• Write maintainable code, participate in code reviews, document important decisions and contribute to shared engineering standards.

Systems, Infrastructure & Collaboration

• Support Docker-based development environments, deployment processes and CI/CD practices.
• Follow secure coding, access control, data handling and operational best practices.
• Communicate progress, blockers, estimates and recommendations clearly and early.
• Collaborate constructively with the development team, business stakeholders and Australian colleagues; clarify requirements rather than making risky assumptions.

Successful candidates must have:

• At least 3 years of professional software development experience, with strong PHP experience.
• Hands-on Laravel experience (or a comparable modern PHP framework), including REST/JSON APIs, validation, authentication and application logic.
• Solid MySQL or relational database skills, including query writing, schema design, joins, indexing and performance tuning.
• Good JavaScript fundamentals (ES6+); experience with a frontend framework or library such as React or Vue is highly regarded. Familiarity with jQuery and legacy frontend code is useful.
• Working knowledge of HTML5, CSS3, responsive layouts and a CSS framework.
• Experience with Git and team-based version control; Bitbucket is preferred.
• Understanding of MVC, object-oriented programming, API integration, testing and maintainable software design.
• Experience with Docker, AWS, Linux or CI/CD is an advantage.
• Practical experience with AI-assisted coding tools (for example Cursor, Claude Code or OpenAI Codex), or clear evidence of actively learning and experimenting with AI-enabled software development. Candidates should explain how they verify output and manage risks.
• Evidence of UI/UX awareness, creative problem-solving or improving an existing product/interface. A formal design qualification is not required; a portfolio, before-and-after example, prototype or clear explanation of improvements is welcome.

Work Arrangements:

• Schedule: 6:00 AM - 3:00 PM (Philippine Time)
• Work Setup: On-site - Be part of a collaborative and energetic team in a professional office environment.
• Location: Parkway Corporate Center, Alabang, Muntinlupa City
