Senior Audio Plugin Software Engineer | C++, Security, Licensing Keys & Backend Infrastructure

Senior Audio Plugin Software Engineer | C++, Security, Licensing & Backend Infrastructure

Mishkal Audio | Remote

We've built a suite of 50 plugins. Now we need someone exceptional to help us turn them into a secure, scalable commercial software company.

Mishkal Audio is developing a suite of professional audio plugins, including EQs, dynamics processing, analog modeling, vocal processing, and other advanced audio tools.

Our founder brings deep subject matter expertise in professional audio engineering and has developed a growing catalog of plugins using C++ and AI-assisted development.

We understand that our current programming capabilities can only take us so far. We're looking for an experienced, hands-on software engineer who can take ownership of the entire technical infrastructure required to launch, protect, maintain, and scale our products.

This is a high-ownership role. You'll be our primary software engineer, working directly alongside the founder.

What You'll Own

Security & Code Auditing

• Audit our existing C++ codebase, including AI-generated code, for vulnerabilities, bugs, stability issues, and performance problems.
• Implement ongoing security improvements, secure coding practices, and automated vulnerability testing.
• Protect proprietary algorithms, source code, compiled plugins, customer information, and licensing infrastructure.
• Implement practical anti-piracy and anti-tamper protections to make unauthorized distribution, reverse engineering, and license cracking more difficult.

Licensing, Subscriptions & E-Commerce

• Build or integrate a secure licensing system supporting perpetual purchases, monthly and annual subscriptions, short-term rentals, trials, and product bundles.
• Integrate payment processing and e-commerce platforms with automated license creation, activation, renewals, expiration, and revocation.
• Manage failed payments, refunds, cancellations, device activations, offline licensing, and customer account recovery.
• Ensure a seamless experience from checkout to download, installation, and activation.

Backend & Customer Infrastructure

• Develop and maintain secure APIs, databases, customer accounts, administrative dashboards, and licensing services.
• Build internal tools for customer support, subscription management, purchase history, license resets, and troubleshooting.
• Establish monitoring, logging, backups, disaster recovery, and reliable cloud infrastructure.

Plugin Compatibility, Updates & Maintenance

• Ensure plugins operate reliably across supported DAWs, including Pro Tools, Logic Pro, Ableton Live, Cubase, FL Studio, REAPER, and others.
• Maintain compatibility across Windows, macOS, VST3, AU, and AAX where supported.
• Build automated testing, compilation, packaging, code signing, installer distribution, and software update systems.
• Push bug fixes, security patches, and feature updates without disrupting existing customers or recording sessions.
• Troubleshoot crashes, performance issues, CPU usage, latency, and compatibility problems.

Development Operations

• Establish proper GitHub repositories, version control, CI/CD pipelines, and secure release processes.
• Organize our AI-assisted development environment, including Claude Code, shared project knowledge, testing, and code review.
• Work alongside the founder to turn new plugin ideas, improvements, and customer feedback into stable commercial releases.
• Evaluate established third-party services instead of unnecessarily rebuilding licensing, billing, authentication, or security infrastructure.

Who We're Looking For

• Strong professional experience with C++, JUCE, VST3, AU, AAX, and commercial audio plugin development.
• A proven history of developing, launching, or maintaining real audio plugins used by paying customers.
• Experience with software licensing, DRM, anti-piracy, and systems such as PACE/iLok, LicenseSpring, or Cryptlex.
• Strong backend development experience, including APIs, databases, authentication, cloud infrastructure, and payment integrations.
• Experience with Stripe, Paddle, or similar merchant processing and recurring billing platforms.
• Strong understanding of application security, software deployment, cross-platform compatibility, and automated updates.
• Ability to independently troubleshoot complex technical challenges and own a product's engineering lifecycle.
• Comfortable working with AI-generated code while applying professional engineering standards.

The Person We're Really Looking For

You're not someone who just writes code. You've actually brought commercial software products to market and understand everything that happens after the software itself is built. You know how to protect it, sell it, license it, deploy it, support it, update it, and keep it running reliably for thousands of customers. You can work independently, make sound architectural decisions, and know when to build something versus integrating an established solution.

We don't need a large engineering department. We need one exceptionally capable engineer who can own this entire technical ecosystem.

Mishkal Audio is building the audio technology. Your responsibility is to build and maintain the engineering infrastructure.

Pay: $115,000.00 - $250,000.00 per year

Application Question(s):

• Commercial audio plugins or desktop software products you've personally developed, launched, or maintained.
• Your experience with software licensing, anti-piracy, and subscription infrastructure.
• Your experience auditing and maintaining C++ software, including AI-generated code.

How you would approach taking an existing catalog of approximately 50 C++ audio plugins from development into a fully secure, supported commercial launch.

• Describe your weaknesses to being a one stop developer for project like this.
