Staff Back - end Engineer (golang/crypto) - Finance - Remote Eligible

Staff Back-End Engineer

Looking for competent Staff Back-End Engineers to design and build the platform's core modules. These engineers will play a foundational role in creating a secure, scalable, and modular banking infrastructure that manages real financial transactions and workflows. But there is an essential requirement for deep experience in cryptocurrency technologies. This engineer will own the module responsible for integrating crypto-specific functionalities, ensuring the digital bank's bridge to blockchain infrastructure is reliable and secure.

Responsibilities

1. Design, document, and implement end-to-end backend modules in Golang.
2. Define and propose an architecture for the assigned module(s); present and align designs with the CTO and peer engineers.
3. Integrate individual modules to ensure architectural consistency across the whole platform.
4. Develop systems with strong workflow and state management for key entities (e.g., payments, transactions).
5. Implement and manage transactional logic, ensuring consistency, durability, and fault tolerance across distributed systems.
6. Work with workflow/transaction management frameworks such as Temporal (or similar).
7. Build RESTful and service-based architectures that can integrate seamlessly with enterprise systems.
8. Collaborate with peers to align on standards, APIs, and design decisions.
9. Uphold a design-first mindset—prototyping and iteration occur after architectural alignment, not as trial-and-error coding.

Qualifications and Job Requirements

• Understanding of digital asset custody, wallets, and transaction flows.
• Familiarity with smart contracts and blockchain transaction management.
