Crypto Blockchain Infrastructure Engineer

job summary

Role Overview

As a key technical leader within our payment and digital asset initiatives, you will drive the high-level design, architecture, and proof-of-concept (POC) development for our next-generation digital asset platforms.

While the global financial landscape rapidly shifts toward decentralized networks, you will ensure we remain highly competitive by designing robust, secure, and scalable architectures for cryptocurrency, tokenized assets, and smart contracts.

This is a high-visibility, hands-on role where you will evaluate vendor ledgers, architect deposit-to-tokenization pipelines, and collaborate with cross-functional bank teams to map out our future-state digital ledger infrastructure.

Key Responsibilities

High-Level Design & Architecture: Map out the integration of digital assets, ledger systems, and tokenization processes (e.g., designing how traditional fiat deposits are securely tokenized).

Lead Proof of Concepts (POCs): Evaluate third-party and vendor ledger systems. Install, configure, test, and determine the optimal toolstack (potentially utilizing FastAPI for rapid prototyping).

System Integration & Messaging: Ensure seamless communication between decentralized ledgers and legacy systems, utilizing ISO 20022 payment messaging formats.

Standards & Compliance: Solid, practical understanding of ISO 20022 payment messaging standards.

Architecture & Setup: Proven ability to design system integrations from scratch, including setting up vendor-provided ledgers, configuring APIs, and establishing deposit-tokenization workflows.

Architectural Communication: Outstanding verbal, written, and visual communication skills, with the ability to articulate complex blockchain/crypto designs to non-technical stakeholders.

Agile Mindset: Comfortable navigating fast-moving, iterative environments with a high degree of autonomy.

Preferred & Nice-to-Have Skills

Banking/Financial Services Experience: Prior exposure to a large-scale bank environment is highly preferred to help navigate communication channels, risk/compliance frameworks, and complex internal architectures.

FastAPI Experience: Practical experience using Python's FastAPI framework for building and testing APIs during POCs.

Legacy Messaging Networks: Any familiarity with the traditional SWIFT network (such as SWIFT Alliance, Web Platform, or SWIFT protocols) is a plus, but not required.
