About Us

At Todyl, we're on a mission to make world-class cybersecurity and networking accessible to businesses of all sizes. Our cloud-native Security Platform brings together SASE, SIEM, Endpoint Security, GRC, MXDR, and more into a unified, single-agent solution purpose-built for MSPs, MSSPs, and mid-market IT professionals.

We're a fast-growing, innovative cybersecurity company focused on simplifying complex security challenges and helping our partners protect their customers against an evolving threat landscape.

Our success is driven by a team that values collaboration, accountability, and continuous improvement. We move quickly, solve complex problems, and take ownership of the technology we build. At Todyl, you'll have the opportunity to make a meaningful impact, tackle challenging technical problems, and help shape the future of cybersecurity.

What You'll Do

• Build and enhance networking and security functionality across proxy, DNS, VPN, firewall, routing, and related services.
• Develop C/C++ data-plane components with attention to correctness, throughput, latency, and resource usage.
• Build Go control-plane services, APIs, and tools for configuring and managing multitenant network services.
• Implement configuration changes that can be validated, applied reliably, and diagnosed when something goes wrong.
• Own well-scoped features and defects from investigation and design through implementation, automated testing, and release validation.
• Diagnose production issues using logs, packet captures, debuggers, profiling, and Linux networking tools.
• Develop tests covering protocol behavior, failure conditions, performance, and regressions.
• Work with engineering, operations, and customer-facing teams to deploy and support services across our global network.

Required Skills & Experience

• 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 developing and supporting production Linux systems or networking software, beyond administering Linux servers or deploying applications.
• Strong proficiency in C, C++, Go, or a similar systems-oriented language, with demonstrated experience building and debugging production Linux systems or networking software.
• Strong understanding of TCP/IP, DNS, routing, sockets, and packet flow, including hands-on experience diagnosing networking problems.
• Practical experience with Linux networking behavior and APIs.
• Understanding of concurrency, synchronization, memory and resource management, process behavior, and failure handling.
• Experience investigating performance or reliability problems and using evidence to identify bottlenecks and root causes.
• Ability to independently investigate unfamiliar code and deliver tested, maintainable changes.
• Clear communication of technical decisions, tradeoffs, progress, and risks.
• Level Expectations
• At the Software Engineer II level, you can independently deliver well-scoped work, make sound implementation decisions, and recognize when to seek input.
• At the Senior level, you can also turn ambiguous problems into practical designs, evaluate data-plane and control-plane tradeoffs, lead changes spanning services, and improve engineering quality through technical guidance and design reviews.
• Level will reflect demonstrated scope, judgment, and ownership.

Nice to Have

• Experience developing firewalls, proxies, VPNs, DNS services, IDS/IPS, or other networking and security products.
• Production development experience in both C/C++ and Go.
• Familiarity with BGP, EVPN, VXLAN, and Linux routing.
• Experience with multitenant configuration management and distributed control planes.
• Experience profiling and optimizing network-intensive applications.
• Effective use of AI-assisted development tools, supported by testing and careful review of generated changes.
