Looking for Philippines-based candidates
Job Role: Sr AI-Augmented Full-Stack Developer / Solutions Engineer
Compensation range: $2,500 AUD - $3,500 AUD / Monthly
Engagement type: Independent Contractor Agreement
Work Schedule: This role is expected to align with the AU business hours (approx. 9 AM - 5 PM, Monday to Friday) for collaboration, but as a contractor, you’ll have flexibility in how you manage your time.
Who We Are: At Hunt St, we help Australian companies hire top remote talent in the Philippines. For this role, you will be engaged directly by the client as an independent contractor. We are not an outsourcing agency. All of our roles are 100% remote so you'll be able to work from home.
Who The Client Is: The company is an established Australian technology company with 20+ years in business, wholesaling IT hardware including industrial solutions and point-of-sale systems. Their work runs on serial numbers, warranties and stock movement, all managed through our long-standing ERP system, Ostendo.
Ostendo works well for them and has API access available, so they are building on it. Nexus is their internal AI transformation program: four AI-enabled applications that will lift productivity, automate repetitive work, put company knowledge at our team's fingertips, and extend Ostendo with new modules.
MVPs already exist for the applications, so you'll start with a clear picture of what we need
Role Overview: We're looking for a senior software engineer who uses AI as an accelerator. You bring strong engineering fundamentals and use tools like OpenAI Codex, Claude Code and Cursor every day to design, build, debug, test and document faster.
You'll own each application end to end:
Requirements → Architecture → Development → Testing → Security Review → UAT → Deployment → Documentation → Handover
The goal is software that is secure, maintainable, well documented and ready for our internal team to support long after handover. Our Brisbane team will supply requirements, business knowledge and heavy involvement in UAT, so you can focus on building it right.
Key Responsibilities:
Application Development
Design and build the four Nexus applications, from front end and back end to database and integration layers
Translate business requirements from the Australian team into practical technical solutions
Integrate Nexus with our Ostendo ERP via its API, adding new modules and capabilities
Use AI-assisted development extensively to move fast, while reviewing and owning every line that ships
AI Integration
Integrate applications with LLM platforms including OpenAI, Claude and Microsoft AI services
Build a knowledge engine for our product specs and documents using RAG, embeddings and vector search
Apply structured outputs, function calling, AI agents and workflow automation where they add value
Choose confidently between AI and conventional software logic for each problem
Software Architecture
Establish a technical architecture built for security, reliability, maintainability, scalability and auditability
Set up separate development, testing and production environments
Explain architectural decisions to our IT team in plain language
Source Code and Version Control
Run professional Git practices: branching strategy, pull requests, code reviews, release management and rollback procedures
Keep all source code in company-controlled repositories with a clear change history
Security
Implement authentication, Microsoft Authenticator / 2FA and role-based access control
Manage API authentication, secrets and keys, database security and encryption
Build in logging, audit trails, input validation and dependency/package security
Protect against common web vulnerabilities and handle confidential company information with care
Review, test and validate all AI-generated code before it is accepted
Testing and UAT
Establish unit, integration, automated and regression testing
Set up UAT environments and support the Australian team through business-process validation
Build robust error handling, logging and monitoring
Documentation and Knowledge Transfer
Deliver system architecture, repository, database and API/integration documentation
Write deployment, environment/configuration, administrator and troubleshooting guides, plus security notes
Run regular knowledge-transfer sessions so our internal team can confidently maintain and support every application
Add clear code comments where they aid understanding and maintenance

Git and professional version control workflows
Authentication, authorization and application security
Cloud deployment and production maintenance
Testing and debugging
Daily use of AI development tools (Codex, Claude Code, Cursor or similar) across design, development, debugging, testing and documentation, with real examples to share
