Job DescriptionSenior Backend Engineer Node.js/TypeScript

We are looking for a Senior Backend Engineer (Node.js / TypeScript) to join a fintech infrastructure team building the next-generation compliance and routing layer for licensed financial institutions essentially a SWIFT for stablecoins.

The core mission: create a global addressing and payments routing system that delivers:

• secure & fast cross-chain transfers

• institutional-grade stablecoin rails

• full Travel Rule (IVMS-101) alignment

• audit-ready transparency and policy enforcement

This is a centralized-by-design rails layer not a bridge, not a DEX.
Think audited controls, deterministic policy engines, strict SLAs, MPC custody integrations, and production-grade financial infrastructure.

You will architect and ship systems where real money moves and real risks exist.

Why this matters now

Institutional stablecoin adoption is scaling rapidly as banks and regulated players move from pilots to production.

This team is building the backbone for that evolution a secure, policy-driven execution layer for compliant global stablecoin settlement.

• Handle CCTP flow, attestations, and proof handling

• Listen to Tron & EVM events and finalize settlement logic

• Build treasury controls, float-monitoring, and rebalancing logic

• Architect an intent ledger & reconciliation layer (no state drift)

• Deliver idempotent APIs, error taxonomies, retries, timeouts

• Stand up observability: logs, metrics, dashboards, SLOs

• Ship evidence bundles & webhook delivery 99.9% SLO

• Define engineering best practices & help hire senior backend peers

Tech & Concepts

• Node.js + TypeScript (must)

• Event-driven distributed systems

• Postgres (indexes, replication, migration strategy)

• CI/CD, SRE practices, SLIs/SLOs

• Kubernetes / ECS, Terraform

• Hands-on MPC custody integration experience

• Designed systems where funds are at risk

Nice to have

• Travel Rule / IVMS-101 familiarity
