Job description

Location: Singapore (on-site / hybrid) Reports to: CTO & Founder

What Makes This Role Different

• You're employee-level early — real ownership, real equity, real influence over what we build and how.
• You'll work directly with our CTO. Architecture and technical direction are set together; you own execution, delivery, and the team on the ground.
• No bureaucracy. Decisions happen in a room (or a chat), not in a committee.

You’ll help hire and lead the engineers who come after you.

What You’ll Actually Be Doing

• Own end-to-end full-stack delivery of our core product — from the payroll module to AI-powered workplace features.
• Turn product ideas into shipped, working features fast — and iterate based on real client feedback.
• Set engineering standards, run code reviews, and mentor and lead a small and growing engineering team.
• Work shoulder-to-shoulder with the CTO on architecture, and with the founder on roadmap and priorities.

Be the technical voice in cross-functional conversations — with product, with leadership, and sometimes directly with clients.

Requirements

1. Product mindset

• Treats the product’s success as your own; focused on outcomes, not just task completion.
• Pushes back constructively when something doesn’t serve the user or the business.

2. Leadership and communication

• Able to lead and mentor engineers — set direction, review work, and raise the bar without crushing morale.
• Communicates clearly across all levels — technical and non-technical stakeholders alike.

Able to keep a team aligned and moving independently.

3. Full-stack engineering experience

• Approximately 5 years of experience building real products as a product-minded engineer.
• Demonstrated track record of shipping end-to-end, not just maintaining existing systems.
• Comfortable across the stack: modern frontend (e.g. React / TypeScript), backend (e.g. Node.js or Python), relational databases (e.g. PostgreSQL), and cloud (AWS).
• Makes pragmatic engineering trade-offs — knows when to build it right and when to ship and iterate.

Nice to Have

• Domain experience in fintech, payroll, or HR tech.
• Experience integrating LLMs / AI into products (e.g. Claude or OpenAI APIs, MCP, agentic workflows).

Early-stage or startup experience.

Tech Stack (Indicative, Not Rigid)

Frontend: React / TypeScript

Backend: Node.js or Python

DB: PostgreSQL

Cloud: AWS

AI: Claude / OpenAI APIs, MCP

What We Offer

• Founding‑team role with meaningful equity.
• Direct, visible impact — what you build ships and reaches clients quickly.
• Salary commensurate with experience.
• Room to grow into a senior technical leadership role as the team scales.
