About the role

We are looking for a C# Developer to contribute to the development and maintenance of an application-protection product built on C# and IL. This person works alongside two senior engineers on implementation and problem-solving, building familiarity with obfuscation and runtime protection. Comfort supervising AI-assisted development and verifying results is part of the role.

What you will do

Contribute to development and maintenance of Dotfuscator, PreEmptive's C# and IL-focused application-protection product.
Work alongside two senior engineers to implement product changes and solve technical problems.
Build understanding of the product's obfuscation and runtime-protection context, including its interaction with customer application builds.
Break down implementation tasks and seek clarification from teammates when requirements or technical approaches are unclear.
Use Claude Code in daily development while retaining responsibility for reviewing and verifying the resulting implementation.
Contribute to adjacent technical tasks when required, using investigation, collaboration, and AI assistance to work beyond the primary stack.

Must haves

Hands-on C# software engineering skills at a mid-level proficiency, of at least 3 years.
Ability to work collaboratively with senior engineers on product implementation and technical problem-solving.
Critical thinking: break problems into clear steps, identify gaps in understanding, and ask useful questions of teammates and AI agents.
Ability to supervise AI-assisted development, review generated code, and verify that implementations achieve the intended result.
Willingness to learn and contribute outside the primary stack, including C++ packages, front-end tasks, and CI/CD, when needed.
Upper-Intermediate English level.

Nice to haves

Familiarity with .NET Intermediate Language (IL) and how C# applications are built and executed.
Experience with code obfuscation, runtime protection, or application-security tooling.
Experience with command-line tools and build-process integrations.
