Full Stack Engineer

About UnlockLand

UnlockLand is a Singapore-based AI technology company building intelligent software for land development, urban planning and pre-development decision-making.

Our platform connects planning policies, land data, development evidence and AI-powered workflows, helping developers, planners and public-sector organisations evaluate opportunities and make better decisions.

We are expanding rapidly and are looking for a hands-on Full-Stack Engineer who can independently build, ship and improve production-ready products.

About the Role

You will work across the entire product stack—from user interfaces and geospatial data to backend services, databases and AI-powered workflows.

You will collaborate closely with product managers, planners, designers and enterprise customers to turn complex requirements into reliable software. You will also build customer-specific POCs, validate new product ideas quickly and develop successful prototypes into scalable production features.

This role is suited to a product-minded engineer who enjoys ownership, moves quickly and can deliver complete solutions without requiring narrowly defined specifications.

Key Responsibilities

Build and maintain full-stack web applications across frontend, backend, database and infrastructure.

Develop intuitive interfaces for land, planning, development and geospatial workflows.

Design APIs, data models and backend services for complex planning and property data.

Build AI-powered features using LLMs, agents, retrieval systems and structured data workflows.

Integrate external datasets, APIs, mapping services and document-processing systems.

Build functional POCs and prototypes for enterprise and public-sector customers.

Turn successful prototypes into secure, reliable and scalable production features.

Work with product managers and domain specialists to understand client requirements and design technical solutions.

Participate in selected client meetings, technical workshops and product demonstrations.

Make practical technical decisions based on delivery speed, maintainability and customer value.

Improve system performance, security, observability and reliability.

Write maintainable code, conduct reviews and establish appropriate testing and deployment practices.

Use AI coding tools effectively while remaining responsible for architecture, code quality and final delivery.

Requirements

Strong hands-on experience building and deploying modern full-stack web applications.

Proficiency in JavaScript or TypeScript and a modern frontend framework such as React or Next.js.

Backend development experience using Python, Node.js or a comparable technology.

Strong understanding of APIs, relational databases, authentication and cloud deployment.

Experience integrating AI models, LLM APIs or AI-powered workflows into real products.

Ability to independently take a product from concept to working prototype and production deployment.

Strong product judgment and ability to work with incomplete or evolving requirements.

Experience using AI-assisted development tools such as Cursor, Claude Code, Codex or similar tools.

Ability to move quickly without compromising security, reliability or maintainability.

Strong problem-solving, communication and cross-functional collaboration skills.

Professional-level English.

Comfortable working in a fast-moving startup environment with significant ownership.

Preferred Experience

Experience with React, Next.js, TypeScript, Python, PostgreSQL, Supabase or similar technologies.

Experience building AI agents, retrieval systems, document-processing pipelines or structured-output workflows.

Experience with GIS, mapping libraries, spatial databases or geospatial data.

Experience building enterprise SaaS, data platforms or workflow software.

Experience delivering enterprise or public-sector POCs.

Familiarity with architecture, urban planning, real estate development, construction or the broader built environment.

Experience working directly with enterprise customers to clarify requirements and resolve technical issues.

A portfolio of products or applications that you have personally built and deployed.

What Success Looks Like

Shipping functional product improvements quickly and reliably.

Turning customer requirements into clear technical solutions.

Building a working POC independently within a short delivery cycle.

Converting prototypes into stable production systems.

Taking ownership of features from architecture and implementation through deployment and monitoring.

Using AI tools to increase development speed while maintaining engineering quality.

Building software that customers actively use in real planning and development workflows.
