What We are Looking For:

We are looking for a Principal Software Engineer to help shape the next generation of Airlock Digital’s macOS and Linux endpoint technology. This is a senior individual-contributor role with broad technical influence. You will set direction through architecture and design work, turn product and customer needs into practical engineering plans, and contribute directly by implementing features, reviewing code, and resolving complex defects.

The macOS/Linux Agent spans operating-system event monitoring and enforcement, privileged services, local policy and data management, secure communications, installation and update workflows, and platform-specific user experiences. You will bring strong macOS and Linux systems judgment to this work, build alignment around important technical decisions, and help other engineers solve difficult problems. You will work across engineering, product, QA, security, support, and cloud teams to improve product quality and customer outcomes.

Key Responsibilities:

- Set and communicate the technical direction for Airlock Digital’s macOS and Linux Agents. Translate product and customer needs into sound designs, architectural decisions, and executable engineering plans.

- Contribute directly to the shared managed-language codebase and platform-specific components by implementing features, reviewing code, and resolving high-priority defects.

- Lead design, architecture, and code reviews. Build alignment around the boundaries between shared Agent capabilities and operating-system-specific integrations while maintaining security, reliability, performance, and maintainability.

- Own technical outcomes for application-control enforcement and Agent lifecycle behavior across supported macOS releases and Linux distributions, including event monitoring, policy evaluation, trusted software handling, installation, updates, recovery, and secure communications.

- Diagnose difficult production issues involving privileged services, concurrency, resource usage, filesystems, process execution, operating-system security controls, package formats, and processor architectures.

- Raise the engineering bar through technical mentorship, knowledge sharing, automated testing, observability, and improvements to build, release, and diagnostic capabilities. Partner with product, QA, security, support, and cloud engineering to manage technical risk and coordinate delivery.
