Backend Engineer, Fintech Excellence

About the role

Fintech Excellence owns the health of payments, accounting and Deel's fintech products (wallets, cards, crypto and payouts). The team watches every financial flow, detects drift early and closes the loop automatically, using AI agents to investigate, verify and fix issues. The role is remote, within a UTC-4 to UTC-9 timezone, with core hours overlapping the Americas team.

Key responsibilities

• Detect problems before customers do, from user intent through to the settled transaction and accounting entry
• Build monitors and reconciliations that find silent failures such as duplicates, stuck states and mismatched balances
• Remove noisy and duplicate alerts so each remaining alert leads to an action or an automated fix
• Investigate incidents across payment service providers, ledgers, wallets, payouts, cards and crypto rails, and fix the code, data model or integration at the root
• Write clear postmortems and turn lessons into guards, tests or monitors
• Build and improve AI agents that triage alerts, investigate with read-only data access, propose or apply fixes and verify results
• Turn runbooks into tools and skills for agents, with maker-checker validation, clear escalation and audit trails
• Partner with payments, accounting, wallets, cards and crypto teams to share fixes and patterns

Required profile

• AI-native: uses AI coding and agent tools such as Claude Code, Cursor or Codex, runs several agents in parallel and knows when not to use AI
• At least 5 years of experience shipping production systems in TypeScript and Node.js or a similar server-side stack, with SQL depth, preferably PostgreSQL
• Production ownership: debugged live, high-volume systems and understood concurrency, idempotency, retries, queues and eventual consistency
• Observability skills: turning logs, metrics and traces into signals for people and agents
• Bias to resolution and clear asynchronous communication in a remote, distributed team

Required skills

• TypeScript and Node.js backend development
• SQL, preferably PostgreSQL
• Observability with logs, metrics and traces
• Bonus: payments, ledgers, reconciliation, card issuing, crypto rails, payment provider integrations, LLM agents, SRE or incident response experience
