About the Product

Secure File Gateway is a gateway that sits between a WAF and the web app backend. It ensures every uploaded file is scanned and sanitized by MetaDefender Core (via ICAP) before reaching the application; no WAF config changes needed. This solves the gap left by WAFs that don't support ICAP, or can't handle CDR-sanitized data.

What You'll Do

• Design, build, and test SFG in C++ or Rust (Windows/Linux) as the transparent proxy between WAF and backend.

• Implement the core flow: intercept uploads → forward to MetaDefender Core over ICAP → return sanitized files, with low latency and high reliability.

• Build multi-threaded, high-concurrency networking components.

• Build and use agentic workflows (e.g., Claude Code, autonomous coding agents) daily for coding, testing, and debugging.

• Work within a Scrum team; collaborate with Product Management; do peer code reviews.

What We Need

• Strong OOP background (Java/C#), willing to learn/work in C++ or Rust.

• Solid multi-threading and network programming skills.

• Comfort with protocol/network-level concepts (TCP/IP, HTTP, proxying).

• Genuine interest in using AI tools in your dev workflow.

• Experience building or using multi-agents

• Good coding/debugging skills, strong communication, self-motivated.

Nice to Have

• ICAP protocol, reverse proxy / gateway experience.

• REST API design.

• Agile/Scrum, Git/Bitbucket/Jira/Confluence/TeamCity.

• DBMS (SQLite,…
