Blockchain Engineer 2

Summary

Prometheum is building regulated market infrastructure that brings securities onto the blockchain through digital asset issuance, custody, clearing, and trading. The Blockchain Engineer 2 will own blockchain features and epics end to end, contribute to technical design, and build secure applications involving custody contracts, transaction signing, orchestration, and key management.

Responsibilities

• Build and maintain secure and optimized blockchain applications
• Own epics end to end, from story writing and pointing through delivery and release
• Build across many different languages taking on the large, complex problems in your team's scope
• Report progress on your epic regularly and accurately, and raise risks before they become surprises
• Partner with senior engineers on technical design, architecture decisions, and future epics
• Demonstrate a passion for learning, building, and constantly improving cutting-edge applications
• Communicate often to encourage tight and quick feedback loops and remove potential blockers
• Use AI coding tools as a default part of your workflow, and review what they produce with the same rigor you would apply to your own code
• Review teammates' code in a way that catches design concerns, edge cases, and test gaps
• Work directly with neighboring systems throughout delivery, not just at the handoff
• Investigate and resolve issues found in QA, UAT, and production

Skills

• 3 or more years of professional software engineering experience building and shipping production software
• Strong blockchain fundamental knowledge including in-depth knowledge of top chains (i.e. Bitcoin and Ethereum)
• Familiarity with basic cryptography commonly utilized by blockchains
• Strong administrative/organizational skills (ability to effectively prioritize, manage time, and meet deadlines on multiple projects)
• Automated testing as a habit rather than an afterthought
• Hands-on experience with AI coding assistants, plus the judgment to know when their output is wrong
• Clear written communication with a strong command of the English language, which matters more on a fully remote team
• Able to reason through technical disagreements with evidence, and to update your view when the evidence shifts
• Authorized to work in the U.S. or Canada
• Experience mentoring or onboarding other engineers
• Background in finance, brokerage, trading, or custody
• Exposure to regulated environments and the audit trails they require
• Experience with Jira, Confluence, or similar
