Senior Software Engineer - Controlone Bridge

About Us:

Cytracom delivers infrastructure software purpose-built to empower managed service providers (MSPs) and IT professionals (ITSPs) with cloud solutions that connect and secure both traditional and hybrid workforces.

Our secure access service edge (SASE) solution provides identity-based network security and connectivity within a single platform that enables businesses to deploy zero-trust networks, enforce compliance and eliminate traditional firewalls and VPNs.

Our unified communications suite (UCaaS) uniquely aligns with the operating needs of MSPs and enables their customers to experience seamless communication and collaboration regardless of physical location.

Here's a closer look at this key role:

Design, implement, and optimize robust backend systems, embedded Rust agents, and Linux-based network appliances, ensuring reliability, security, and high performance. Leverage deep expertise in Linux server management, network engineering, and embedded systems to deliver scalable solutions, enable rapid debugging and recovery, and optimize low-level and high-level packet routing decisions.

Responsibilities

• Architect, develop, and maintain Linux-based systems and embedded Rust agents for the ControlOne Bridge product.
• Design and implement network configurations and protocols to ensure optimal performance and security for a SOHO router/firewall.
• Manage and troubleshoot Linux servers at scale in both customer environments and private cloud environments.
• Analyze and optimize network performance by understanding Linux's frame and packet routing decisions.
• Implement and maintain observability stacks (metrics, logs, events, traces) to ensure system visibility and rapid incident response for distributed environments.
• Debug complex production issues, including deep stack trace analysis for Rust agents and network troubleshooting for Linux systems.
• Collaborate with other engineers to deliver seamless full-stack features and maintain API contracts for the ControlOne platform.
• Ensure security and compliance best practices are embedded throughout the software and appliance lifecycle.
• Automate build, deployment, and monitoring workflows using CI/CD pipelines, infrastructure as code, and tools specific to embedded development and Linux server management.
• Write clear, maintainable documentation and contribute to a culture of operational excellence and continuous improvement, specifically for Linux server management and networking practices.

Core Competencies

• Advanced proficiency in Python for backend programming and Rust for embedded agent development.
• Expertise in Linux server administration and management at scale.
• Deep understanding of computer networking (TCP/IP, HTTP, DNS, routing protocols, firewalls, load balancing, security).
• Strong knowledge of the Linux network stack.
• Experience with embedded systems development and firmware updates.
• Expertise in modern observability stacks (Prometheus, Grafana, OpenTelemetry, ELK/Loki) for both application and Linux server monitoring.
• Performance analysis and troubleshooting using eBPF, profilers, distributed tracing tools, and Linux system tools (e.g., tcpdump, iptables, nftables, iproute2).
• Debugging complex issues using stack traces, core dumps, log/event correlation, and network packet analysis.
• Familiarity with containerization (Docker, Kubernetes) and cloud-native deployment patterns, specifically for Linux-based systems.
• Experience with version control (Git), CI/CD systems (GitHub Actions, CircleCI, Argo), and ticket management (Jira, Azure DevOps) for both application development and Linux infrastructure management.
• Strong written and verbal communication skills; ability to document and explain technical concepts clearly, especially related to Linux server management and networking.

Our Benefits:

• Medical, dental, and vision insurance is available
• 401K
• Disability and Life Insurance
• Paid vacations and holidays
• Flexible PTO policy
• Casual, laid-back work environment
