Software Engineer II / Senior Software Engineer – Endpoint Agent

Todyl•Atlanta, GA

3d•$160,000 - $190,000•Hybrid

About The Position

Build and maintain Todyl’s Go-based endpoint agent and platform-specific integrations for customers’ Windows, macOS, and Linux devices. The agent delivers networking and security capabilities that must work reliably across diverse customer environments. The role involves operating-system APIs, background services, networking, concurrency, and production troubleshooting. The position requires strong systems-programming experience in at least one operating system and the ability to independently deliver well-scoped features and resolve difficult defects. Endpoint-agent experience is valuable, but relevant experience with native services, networking clients, storage, device management, or other OS-integrated software is also applicable. Expertise in all three operating systems is not required. This is a hybrid/in-office role, with a collaborative hybrid work model and offices in Denver’s LoDo neighborhood, Midtown Atlanta, and Augusta, Georgia. Level—Software Engineer II or Senior Software Engineer—will reflect demonstrated scope, judgment, and ownership.

Requirements

Typically 4+ years of professional software engineering experience, with demonstrated ownership of production software; relevant depth and delivery experience matter more than a strict tenure cutoff.
Experience building and supporting software that interacts directly with operating-system APIs, such as native services, networking software, endpoint tools, or other systems-level applications.
Strong proficiency in Go, or substantial C, C++, or Rust experience and willingness to work primarily in Go.
Practical understanding of concurrency, synchronization, process and thread behavior, resource management, and failure handling.
Ability to independently investigate unfamiliar code, identify root causes, and deliver tested, maintainable fixes.
Clear communication of technical decisions, tradeoffs, progress, and risks.
Working knowledge of TCP/IP, DNS, routing, sockets, and VPN concepts, with experience investigating networking behavior.
Strong systems-programming knowledge on at least one of Windows, macOS, or Linux.

Nice To Haves

Production experience with endpoint agents, VPN clients, device-management tools, or security products.
Experience with cgo or integrating Go with C/C++ libraries.
Cross-platform development experience and familiarity with platform-specific networking or security APIs.
Socket programming using Winsock or BSD sockets.
C# or Swift experience.
Familiarity with SASE, EDR, or endpoint-security concepts.
Effective use of AI-assisted development tools, supported by testing and careful review of generated changes.

Responsibilities

Develop and maintain the Go-based agent, including cgo integrations for platform-specific functionality.
Build and enhance agent capabilities supporting SASE and endpoint security.
Integrate with Windows, macOS, and Linux APIs for networking, processes, services, and other system-level functionality.
Own well-scoped features and defects from investigation and design through implementation, automated testing, and release validation.
Diagnose production issues using logs, debuggers, traces, packet captures, and reproducible tests.
Improve reliability, resource usage, and behavior across operating-system versions and changing network conditions.
Work with engineering and customer-facing teams to resolve escalated issues, communicate risks, and coordinate dependencies.
At the Senior level, turn ambiguous problems into practical designs, evaluate cross-platform tradeoffs, lead changes spanning components, and improve engineering quality through technical guidance and design reviews.
