Full-Stack Software Engineer (TypeScript)

About the role

Tanatasa builds an online store so AI assistants can shop as easily as people. As a full-stack software engineer you will ship across the whole product: the React storefront, the agent API and MCP server, checkout and payments, and the catalogue and supplier pipelines behind them. The position is based in Singapore and is full-time.

Key responsibilities

• Build and ship features end to end across the React Router storefront, Cloudflare Workers APIs and the D1 (SQLite) database.
• Extend the agent API and MCP server that AI assistants use to search the catalogue, compare products, build carts and complete checkout.
• Improve checkout, payments (Stripe), delivery and order tracking so purchases are reliable and easy to approve.
• Maintain catalogue, pricing and supplier pipelines, product feeds (Google Merchant Center, OpenAI and Meta) and the jobs that keep them fresh.
• Keep the site fast, crawlable and well structured: Core Web Vitals, structured data, sitemaps and accessible UI.
• Write tests, review code, watch production logs and fix issues at the root; use AI coding tools and design APIs and data that AI agents can use safely.

Required profile

• 3+ years of professional software engineering experience shipping web products to production.
• Degree in computer science or a related field, or equivalent practical experience.
• Eligible to work in Singapore.
• Clear written communication and product sense about how shoppers find, compare and buy.

Required skills

• TypeScript and modern JavaScript, with real experience in React and HTTP APIs.
• Solid SQL and data modelling, including designing tables, writing efficient queries and planning migrations.
• Nice to have: Cloudflare Workers, Pages, D1, R2 or other edge/serverless platforms; MCP servers, LLM tool calling or agent integrations; ecommerce experience; technical SEO and schema.org structured data.
