• About the Role.
• Sunsulution / 21Sunpassion (owner of the Bearhouse brand) is scaling toward a planned public listing, and our IT function operates on a lean, high-leverage model: a small team of senior engineers who use modern AI tooling to deliver at scale.
• The Senior Product Engineer is an end-to-end owner. You will take business problems and deliver production software from design through deployment and ongoing maintenance. Your first mandate is to build our Vendor Invoice Intake system replacing a manual, paper-and-email process in Finance/AP with a fully digital workflow that carries a complete, audit-ready trail suitable for external audit under our listing timeline.
• You will work alongside AI coding tools as a standard part of your workflow, while retaining full ownership of the quality, security, and correctness of everything you ship.
• Design and build production-grade, full-stack internal applications (frontend, backend, database).
• Own the Vendor Invoice Intake system end to end: vendor portal, 3-way match (PO / Goods Receipt / Invoice), DOA-based approval workflow, and immutable audit logging.
• Integrate with SAP and enterprise identity via Entra ID (OIDC).
• Use AI coding tools (Claude Code, Cursor, GitHub Copilot) effectively while owning code review, testing, and security validation of all output.
• Build reusable platform components (authentication, workflow engine, audit logging) to accelerate delivery of subsequent internal applications.
• Partner closely with Finance and business stakeholders to understand processes before building.
• Proven track record of shipping production software as a full-stack engineer (demonstrated through portfolio or work samples, not coursework alone).
• Frontend: React / Next.js.
• Backend: Node.js or Python.
• Database: PostgreSQL / SQL Server, with the ability to design schemas and write SQL independently.
• REST API design; authentication via OAuth2 / OIDC.
• Demonstrated ability to use AI coding tools in a real workflow, with the judgment to review, debug, and take full ownership of AI-generated code. A disciplined prompt review test security-check loop is expected.
• A security- and correctness-first mindset: input validation, access control, and logging built in from the outset rather than added later.
• Strong communication of technical trade-offs, including design rationale and associated risks.
• Preferred Qualifications.
• Working knowledge of Finance / Accounts Payable processes (invoicing, PO/GR matching, approval hierarchies, internal controls).
• Prior ERP integration experience (SAP Layer, Microsoft Dynamics 365) or general system-to-system integration (API, webhook, file, EDI).
• Experience delivering systems in a compliance or audit context (PDPA, ITGC, or SOX-equivalent controls), or systems that serve as a system of record.
• Experience establishing CI/CD, automated testing, or observability.
