Profil recherché
### You are a great match if:* **Experience:** 5+ years in Node.js/TypeScript. You’ve ideally seen a startup grow
* **Precision Mindset:** You understand that in fintech, a bug isn't just a ticket; it's a financial consequence. You care about decimal precision and idempotency.
* **Pragmatic Architecture:** We don't follow a named architecture style. We structure our code around business logic, clear entry points, explicit boundaries, and readability by anyone on the team. We care about code that makes sense, not code that follows a manifesto.
* **Product-Minded Engineering:** You don’t just "write tickets." You understand the business logic behind the code and take ownership of the features you build. You enjoy collaborating with product stakeholders to ensure the technical solution perfectly serves the user experience.
* **Domain Curiosity:** A background in finance or fintech is a plus, but not a requirement. Private equity has its own logic and vocabulary; we'll teach you the domain. What matters is that you're genuinely curious about how it works.
