About CAST

CAST is the market leader in Software Intelligence. Its unique technology thoroughly examines the structure of complex software systems, with MRI-like precision. It delivers accurate, actionable, and automated views of software architecture, critical flaws, quality grades, sizing metrics, open-source usage, and cloud readiness levels. Hundreds of companies rely on CAST for greater objectivity in crucial business decisions, faster application modernization for Cloud, raising the quality and security of their custom software.

Founded more than 25 years ago and backed by nearly $200 million in R&D, CAST’s rapid analysis technology and its advanced ‘MRI for Software’ drive IT transformation and enable automation at the world’s largest systems integrators, hundreds of Global 2000 enterprises, and government agencies, in North America, Europe, India and in China.

CAST provides two sets of products of different technologies, implementation models, and usage:

• CAST Highlight is a SaaS product capable of performing rapid application portfolio analysis. It analyzes source code of applications to measure their cloud readiness, to analyze their composition, resiliency, and technical debt.
• CAST Imaging is an on-premises product (also cloud version since 2025) that can run for reverse-engineers all database structures, code components, and interdependencies in custom-built applications. It provides interactive and accurate architecture blueprints, data-call graphs, and end-to-end transaction flows.

Context

Building Context-Aware Remediation Recipes for Security & Performance Findings in Code.

We work at the intersection of Software Intelligence and Artificial Intelligence, helping organizations improve the security, performance, and quality of their applications. Our mission is to transform static analysis findings (from CAST Imaging and other tools) into actionable remediation insights that developers and AI agents can apply safely and efficiently.

The project aims to design and implement an AI-assisted remediation knowledge base that recommends context-aware fixes for code issues across multiple technology stacks. The goal is to ensure that each proposed fix balances safety, impact, best practices, and ease of implementation.

Proposed work

This project invites you to explore how AI can guide developers toward safe and effective code fixes. Your milestones will include:

• Analyzing CAST Imaging findings across several stacks (Java/Spring, JavaScript/React, .NET, etc.).
• Defining recommended remediations per issue type, including primary fixes, alternatives, and justifications.
• Using LLMs to generate, validate, or refine remediation solutions.
• Prototyping an AI-readable remediation recipe database with metadata (severity, stack, context, side-effects).

Team:

Interns will be joining the CAST R&D team, a dynamic and innovative group of professionals specializing in software research and development. The team consists of experienced software engineers, data scientists, and industry experts who are passionate about pushing the boundaries of software technology. Working in this team offers:

- Exposure to cutting-edge research and development in software technology.

- Opportunities for mentorship and learning from seasoned professionals.

- A collaborative environment where creativity and innovation are encouraged.

- Involvement in projects that have a tangible impact on the industry.

 

Required Skills

To be successful in this internship, candidates should possess:

• A Bachelor’s degree (or currently pursuing) in Computer Science, Engineering or a related field.
• Good programming skills
• Familiarity with static analysis, secure coding, or performance optimization concepts.
• Understanding of machine learning or LLM-based reasoning.
• Strong analytical abilities and attention to detail.
• Ability to communicate clearly and collaborate with technical teams.

Main Technology

The internship will involve working with various technologies, including but not limited to:

• Python
• LLMs and embeddings (OpenAI, Hugging Face)
• Similarity search / vector databases
• Data ingestion pipelines (package managers, Git, SBOM)
• Hybrid AI + human validation workflows
