Kerja Full-Stack Engineering Intern, Gaji tinggi SGD 700 di Finprojections - Maukerja

About Finprojections
Finprojections is a Singapore-based finance advisory firm for startup founders and the investors who back them. We're becoming an AI-native CFO office, with AI built into how we deliver finance work.

For founders, we help with fundraising readiness, financial modelling, stress testing and ongoing CFO support. For investors, we build portfolio management software. We also run finance education and recruitment programmes.

About the role
We're hiring a full-stack engineering intern to help build and ship a live web app used by startup founders and their investors.

The app brings a startup's financial data into one place and connects it to the tools founders already use:

• Where data comes from: it pulls numbers from Xero and Google Sheets and keeps them in sync automatically.
• Where data lives: one PostgreSQL database, with each company's data kept separate.
• How people use it: founders work in the web app or ask Claude, which connects through our MCP server.
• Who sees what: investors a founder invites get read-only access in Claude, limited to what the founder shares.
• AI: built-in AI features run on Google's Gemini.

The product is already running in production, so you'll start on real code, not a blank project.

What you'll work on

The app is three TypeScript services sharing one PostgreSQL database, and you'll work across all three.

• Web app (React): build and polish the screens founders use to view and manage their data.
• Backend (Node.js, Express): add API routes, data models and database migrations, and keep the Xero and Google Sheets connections reliable.
• MCP server: build the tools Claude uses to read and update a company's data, with investors limited to what founders share.
• Integrations: Xero and Google Cloud (Sheets, Drive and Docs APIs, Google sign-in), plus AI features built on Gemini and Claude.
• Deployment: move the app to AWS and run it there, monitor the background refresh jobs, and fix what breaks in production.
• Quality and security: write tests, set up automatic test runs (CI) on GitHub, and help prepare for client security reviews.

What you need

• Solid TypeScript or JavaScript, with React on the front end and Node.js on the back end.
• SQL and a relational database, ideally PostgreSQL.
• Everyday Git and GitHub: branches, pull requests and code review.
• Hands-on AWS: you've deployed an app there and kept it running, using services like EC2, ECS or App Runner, RDS for PostgreSQL, and IAM.
• Google Cloud and OAuth 2.0: enabling APIs, setting up consent screens and credentials, and building sign-in and account-connection flows.
• You can open an unfamiliar codebase of 60,000+ lines and explain how its parts fit together within your first week.
• No finance background needed, but you must be keen to learn what a P&L, a forecast and a cap table are.

Nice to have

• Prisma, Vite or Express.
• Building with LLM APIs (Gemini, Claude or OpenAI), function calling, or the Model Context Protocol (MCP).
• Third-party APIs such as Xero, Google Workspace or Stripe.
• Background job queues and scheduled tasks.
• Setting up CI with GitHub Actions.
• Coursework or interest in finance, accounting or startups.
