Cryptography Engineer Internship information

What does a cryptography engineer intern do?

A Cryptography Engineer Intern assists in designing, developing, and testing secure cryptographic systems and protocols. Their work typically involves supporting senior engineers in implementing encryption algorithms, analyzing security vulnerabilities, and conducting research on cryptographic techniques. Interns may also help review code for security flaws and contribute to the development of secure software applications. This role offers hands-on experience with cutting-edge security technologies and fosters an understanding of how cryptography protects sensitive information.

What are the key skills and qualifications needed to thrive as a cryptography engineer intern?

To thrive as a Cryptography Engineer Intern, you need a strong foundation in computer science, mathematics (especially number theory and algebra), and familiarity with cryptographic algorithms, typically supported by coursework or relevant academic experience. Familiarity with programming languages such as Python, C/C++, and use of cryptographic libraries and tools (e.g., OpenSSL, GPG) is essential. Attention to detail, analytical thinking, and the ability to work collaboratively are crucial soft skills in this role. These skills ensure secure implementation and analysis of cryptographic protocols, contributing to robust data protection and system security.

What types of projects or tasks can I expect to work on during a cryptography engineer internship?

As a Cryptography Engineer Intern, you will typically assist with designing, analyzing, and implementing cryptographic protocols and algorithms. Your responsibilities may include supporting code reviews, performing security assessments, and helping to integrate cryptographic solutions into existing applications. Interns often work closely with senior engineers and security teams, gaining hands-on experience with real-world encryption challenges while contributing to projects that protect sensitive data. This role provides a unique opportunity to learn about the latest advancements in cryptography and develop practical skills in secure software development.

What is the difference between Cryptography Engineer Internship vs Cryptography Engineer?

AspectCryptography Engineer InternshipCryptography Engineer
Required CredentialsTypically pursuing or recent graduate in Computer Science, Cybersecurity, or related fieldsBachelor's or Master's in Computer Science, Cybersecurity, or related fields; relevant certifications may include CISSP, CEH

Job description

Andalusia Labs is building foundational economic infrastructure for programmable global markets, connecting capital, computation, and coordination across the internet. Our work sits at the intersection of distributed systems, finance, and machine intelligence, with the goal of growing the world’s programmable GDP.

Our team has shipped massively scalable systems and products at Coinbase, Google, AWS, Microsoft, X, TikTok, Goldman Sachs, and High‑Frequency Trading firms. We are backed by Coinbase, Mubadala, Lightspeed, Bain Capital, Pantera, Framework, Digital Currency Group, Proof Group, Nima Capital, Naval Ravikant, Arthur Hayes, and founders, GPs, and executives from organizations like Founders Fund, Google, and Coinbase.

Role

We are hiring a New Grad Software Engineer to help build systems that power programmable markets. You will contribute to core services, ship high‑performance code, and learn across the stack. You will work alongside founders, senior engineers, and product partners to turn new primitives into production systems that handle high usage.

Responsibilities
  • Contribute to core services across networking, consensus and execution, tokenization, exchange, settlement, and data pipelines
  • Design, implement, and operate high‑quality services in C++, Rust, Go, or Solidity with guidance from senior engineers
  • Profile and improve performance for throughput, tail latency, memory, storage, and network efficiency
  • Build correctness and safety with unit tests, property‑based testing, fuzzing, static analysis, and thorough reviews
  • Support production reliability with clear SLOs, alerting, dashboards, and participation in incident response after onboarding
  • Create and maintain internal libraries, developer tooling, and CI to speed delivery and raise code quality
  • Write clear design docs that explain tradeoffs and support sound technical decisions
  • Collaborate with peers in design and code reviews and contribute to a high engineering bar
  • Partner with product, research, security, and go‑to‑market to scope milestones and ship new capabilities
  • Learn, model, and help implement financial primitives and risk logic with rigorous testing and telemetry
Requirements
  • BA/BS in Computer Science, Computer Engineering, Electrical Engineering, or a related technical field, or equivalent practical experience
  • 0 to 2 years of experience through internships, research, or significant projects working with at least one of these languages (C++, Rust, Go, Solidity)
  • Strong understanding of distributed systems, data structures, algorithms, and software design
  • Experience building performant applications in internships, research, or significant projects
  • Exposure to compilers, runtimes, optimization, or static analysis through internships, research, or significant projects is a plus
  • Familiarity with Git, continuous integration, and automated testing for C++, Rust, Go, and or Solidity stacks
  • High ownership, ability to learn quickly with minimal guidance
  • Ability to work in a fast‑paced environment and across the product engineering stack
  • Clear written and verbal communication
Bonus
  • MA/MS, PhD, or advanced degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical field, or equivalent practical experience
  • Familiarity with cryptography, key management, TEEs, or zero‑knowledge systems
  • Experience or coursework in fintech, algorithmic trading, or financial primitives
  • Experience with React, Node, and/or TypeScript
  • Interested in startups.
