Job description

We are seeking a visionary and hands-on CTO to lead the design, development, and scaling of a new Payroll SaaS product. This is an opportunity to build an entire system from the ground up—architecture, team, product, and infrastructure—in a lean, product-focused environment.

You’ll collaborate closely with business stakeholders to ensure the product is not only technically robust but also commercially viable and aligned with market needs.

Key Responsibilities

• Lead the technical design of the payroll system, including core engine (salary calculations, CPF/tax compliance, leave integration, etc.), security, and scalability.

• Write high-quality code in the early phase, set development standards, and gradually build and mentor a technical team.

• Ensure the system meets local statutory requirements (e.g., Singapore MOM, CPF, IRAS, etc.) and implements industry-standard data protection protocols.

• Work closely with product and business teams to define and prioritize features based on customer needs and feedback.

• Own infrastructure decisions (cloud providers, CI/CD pipelines, backup, monitoring).

• Architect for future scale to support multiple countries or complex payroll structures.

• Stay ahead of technological trends and ensure the tech stack is modern, secure, and efficient.

Requirements

• 5+ years of experience in software engineering, with at least 2 years in a leadership or CTO role.

• Proven experience building and deploying B2B SaaS products (preferably HR or FinTech systems).

• Strong backend engineering skills (Node.js, Python, or similar).

• Solid understanding of local payroll processes.

• Experience with relational databases (e.g., PostgreSQL), cloud infrastructure (AWS, GCP), and APIs.

• Ability to work independently, take ownership, and drive both technical and business outcomes.

• Prior experience building a payroll or HRMS product

• Knowledge of financial/payroll integration APIs (banks, IRAS, CPF, QuickBooks, etc.)

• Strong UX sensibility for internal admin tools
