Job description

Jora Malaysia will close on 9th September 2026. Thank you for being with us, we are cheering you on as you continue your career journey.

We are a Malaysian technology company developing a specialist AI-powered tax advisory and research platform designed specifically for Malaysian taxation.

Our platform combines artificial intelligence with real-world professional tax expertise, enabling individuals, businesses and tax and finance professionals to obtain practical tax guidance, research Malaysian tax legislation and guidance, and analyse tax-related documents through a digital platform.

The platform uses technologies including Generative AI, Retrieval-Augmented Generation (RAG), semantic search, specialised AI agents, document analysis and multilingual text and voice capabilities.

We are now building our in-house technology team to further develop the platform, enhance its AI capabilities and introduce new features.

For the advertisement, I would keep the requirements quite targeted. You need someone who can take over and improve an existing system, not someone whose AI experience is mainly theoretical.

Job Scope – AI & Software Engineer

The role will be responsible for the ongoing development, maintenance and enhancement of the AI platform, working closely with the founder and content team.

Key responsibilities:

Manage and enhance the AI components of the YourTax platform, including RAG, retrieval, prompts, AI agents and response-generation workflows.

Improve the accuracy, relevance and consistency of AI-generated tax responses, including investigating hallucinations, incorrect retrieval and source-citation issues.

Manage the ingestion, indexing and retrieval of Malaysian tax legislation, Public Rulings, guidelines, case law and YourTax proprietary content.

Develop and improve document analysis capabilities, including user-uploaded financial statements, tax computations, tax returns and supporting documents.

Develop and enhance existing and new YourTax product features across the web application.

Troubleshoot and resolve issues involving the AI engine, APIs, database, backend services and integrations.

Work on multilingual AI functionality across English, Bahasa Malaysia, Mandarin and Tamil, including text and voice features.

Monitor AI performance, response quality, latency, token/API usage and system reliability.

Conduct technical testing and support UAT, staging and production deployments.

Maintain proper development, testing and production environments and ensure changes do not disrupt the live platform.

Maintain technical documentation covering system architecture, AI workflows, integrations, deployment processes and system access.

Implement appropriate version control, backups, access controls and deployment procedures.

Work with external developers/vendors where necessary while ensuring that YourTax retains sufficient internal technical knowledge and control of the platform.

Evaluate and implement new AI models, tools and technologies where they can improve YourTax's performance or functionality.
