Description

Software Engineering Intern – Post-Quantum Cryptography

Duration: 6 months

Location: Paris, Oxford, Remote

Start Date: ASAP

💼 About The Role

We are looking for a motivated Software Prototype Intern to help integrate and benchmark our post-quantum cryptographic libraries PQMicroLib-Core, PQCryptoLib-Core, and PQCryptoLib-SDK with higher-level software solutions.

This internship focuses on building practical integration scenarios on top of our cryptographic core, validating real-world usability, and benchmarking performance against existing alternatives. The goal is to create credible use cases that support product strategy, customer discussions, and future R&D priorities, while identifying performance bottlenecks and improvement areas.

⚒️ What You’ll Be Doing

Develop integration scenarios using PQMicroLib-Core and related libraries with higher-level software components.
Explore real-world use cases using open-source and proprietary software.
Perform benchmarking and performance analysis of cryptographic operations.

Compare results with existing alternatives and identify performance bottlenecks.

Propose and validate potential optimizations.

Produce technical documentation and internal demonstrations.

Work closely with R&D engineers to validate feasibility and reduce technical risk

🎯 Required Skills And Qualifications

Currently pursuing or recently completed a Master’s degree in Computer Science, Software Engineering, Cybersecurity, or a related field.
Proficiency in C/C++ and Python (or similar systems/programming languages).
Basic understanding of cryptography and secure software design.
Experience with Linux and open-source development environments (embedded is a plus).
Strong analytical mindset and interest in performance engineering.
Clear written and verbal communication skills.
Interest in post-quantum cryptography is a strong plus.

📈 Expected Outcomes

Integration Demonstrations – Two working proof-of-concept integrations built on top of PQMicroLib-Core.
Benchmarking & Analysis – Clear performance benchmarks, comparison with alternatives, and identified bottlenecks.

Documentation & Knowledge Sharing – Integration guides, benchmark reports, and final presentation to the team.

Strategic Impact – Results that can be reused by product, sales, and partnerships to support customer discussions.

🧠 What You’ll Gain

Hands-on experience with post-quantum cryptographic software.
Exposure to real-world integration and performance challenges.
Direct impact on product strategy and customer-facing use cases.
Mentorship from experienced engineers and security experts.
Visibility across engineering, product, sales, and management teams.
