Proof of work

The team

Kraken is looking for an enthusiastic and skilled Senior Custody Engineer to join a newly created team and project within Kraken. Our mission is to move the economy away from fiat to stablecoins. People should not have to go through a centralized body to custody their money. Banks fail and mismanage customer funds all the time. DeFi gives the power back to the people - with the convenience of cash but the safety of digital assets. We are building embedded finance, but on DeFi rails. Enabling developers to open up DeFi wallets for their users, both self-custody and multi-sig, through easy-to-use SDKs for full onboarding and management for their accounts. 

We’re seeking a strong communicator and a collaborative team player who can decompose complex problems into manageable tasks. You’ll work alongside engineers across the team and organization, learning and exploring innovative ways to address issues and improve workflows.

This role is open to onsite work in San Francisco or remote work within PST hours.

The opportunity

• Build robust backends that handle wallet management, payments, and treasury functionalities

• Strong understanding of authentication protocols, key management and access controls

• Experience implementing commonly used cryptographic techniques for self or joint custodial solutions

• Design and implement APIs that developers can integrate easily into their applications

• Ensure system security and reliability in handling stablecoin transactions across jurisdictions.

• Develop scalable infrastructure for onboarding users in key target markets

Skills you should HODL

• Proficient in building highly scalable backend systems using languages like Python, Go, Rust, or Node.js

• Strong experience working with blockchain technologies, DeFi protocols, and stablecoins

• Expertise in designing secure and efficient APIs

• Knowledge of key management and cryptographic methods

• Familiarity with integrating on/off ramps and payment systems

• 5+ years of backend engineering experience, ideally in fintech or blockchain sectors

• Highly autonomous and able to execute complex technical projects independently
