Backend / Fullstack Engineer, AI-first

This is a fully remote position, open to applicants in Chile.

📋 Description

• Develop and enhance tools and services within the B2B domain: transaction management, counterpart reconciliation, and partner support.

• Design and operate automated workflows — including agents that manage end-to-end B2B flows where manual intervention was previously necessary.

• Work across the entire stack: robust backend, integrations, and the internal product layer that supports it.

• Integrate with Salesforce and existing back-office flows.

• Automate operational processes that currently hinder the growth of the B2B channel.

• Refactor and strengthen legacy code with the same attention to detail as new code.

⛳️ Requirements

• Strong experience as a **senior backend or fullstack developer** in **Node.js / TypeScript** and **AWS**.

• Experience building in **B2B** domains or managing complex integrations between systems/counterparts.

• Work with an **AI-first** approach: utilizing agents and AI tools in your development process as the standard, not the exception.

• Engineering judgment in real-money systems: idempotency, eventual consistency, reconciliation, and resilience.

• Know when to automate with an agent and when not to — and design the guardrails for when the model makes mistakes.

🏝️ Benefits

• 100% remote in LATAM · time overlap with Chile.

• Real technical challenges: eventual consistency, idempotency, reconciliation, and resilience.

• A team that understands that **speed without quality in fintech is an existential risk**.

• Holidays based on your location + flexible rest policy.
