The posting

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.

Key Responsibilities

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

Required Qualifications

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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
