Job description

Core Competencies:

• Deep understanding of modern cryptography: Proficiency in symmetric and asymmetric encryption, hashing algorithms, key management, and cryptographic protocols. Blockchain protocols experience is a plus.
• Secure coding expertise: Demonstrated ability to write secure, efficient, and well‑documented code in Go, C++, C, and Rust, with a focus on cryptographic implementations.
• Systems thinking: Ability to analyze complex systems, identify potential vulnerabilities, and design robust security solutions within a distributed architecture. Experience with Hardware Security Modules is a plus.
• Strong problem‑solving skills: Capacity to troubleshoot cryptographic issues, analyze security threats, and develop effective mitigation strategies.
• Excellent communication and collaboration: Ability to clearly explain complex cryptographic concepts to both technical and non‑technical audiences.

Technical Skills:

• Develop and implement high‑quality, secure code for cryptographic controls throughout our infrastructure.
• Review code throughout the technology stack and help engineering teams resolve issues related to security guardrails.
• Foster an efficient testing culture while reducing technical debt and unnecessary processes.

Complexity and Impact of Work:

• Build robust, resilient components that are easily integrated by other teams to ensure asset and data security.
• Develop and maintain threat models for cryptosystem guarantees, both internal and external. Monitor technical debt and proactively identify areas for improvement.
• Lead or substantially contribute to medium and large Security Team initiatives with minimal oversight. Coordinate team members across engineering boundaries and drive projects from inception to completion.
• Break complex projects into manageable tasks with accurate time and scope estimates. Present options clearly, analyze trade‑offs thoroughly, and provide well‑reasoned priority recommendations.
• Deliver work that aligns with departmental objectives, subject to review upon completion. Take ownership of tactical business targets that affect team performance.

Organizational Knowledge:

• Understand and help implement the company's strategy by participating in planning and defining the Security Team's strategic goals in alignment with Anchorage Digital's overall objectives.
• Stay alert to emerging company objectives and industry trends that could affect organizational success.
• Consider security holistically across the entire product ecosystem while fostering a security‑first company culture.
• Balance speed of delivery with careful planning and precision.

Communication and Influence:

• Share knowledge broadly across the team while preventing single points of failure.
• Mentor and guide engineers throughout the Engineering team. Help them understand security's impact on Anchorage Digital's strategic goals, enabling them to develop new technologies and services safely with appropriate oversight.
• Collaborate across teams to solve problems, review specifications, and engage in technical discussions. Communicate insights and recommendations clearly to improve processes and address technical debt.
• Demonstrate empathy by understanding others' context, needs, motivations, and concerns—adapting communication style to maximize effectiveness.

You may be a fit for this role if you have:

• Cryptography: You possess a strong foundation in applied cryptography, including symmetric/asymmetric encryption, hashing algorithms, digital signatures, key exchange protocols, and common cryptographic libraries.
• Security Architecture and Implementation: You can contribute to the design and implementation of secure systems, with a focus on security best practices and industry standards.
• Hardware Security Modules (HSMs): You have experience configuring and using HSMs for secure key generation, storage, and management, and understand their role in protecting sensitive cryptographic operations.
• Authentication and Authorization: You understand and can implement various authentication and authorization mechanisms, including multi‑factor authentication, OAuth 2.0, and role‑based access control (RBAC).
• Threat Modeling: You can identify and assess potential threats to systems and applications, and effectively prioritize mitigation strategies.
• You have developed "computer science fundamentals", i.e. concurrency, algorithms, and data structures.
• You genuinely care about code quality and test infrastructure.
• You prioritize security, end‑user experience, and business value over "cool tech."
• You self‑describe as some combination of the following: creative, humble, ambitious, detail‑oriented, hardworking, trustworthy, eager to learn, methodical, action‑oriented, and tenacious.

Although not a requirement, bonus points if:

• In your mind the word "crypto" stands for cryptography, not cryptocurrency.
• You read blockchain protocol white papers for fun, and stay up‑to‑date with the proliferation of cryptoasset innovations.
• You were emotionally moved by the soundtrack to Hamilton, which chronicles the founding of a new financial system.
