Senior Software Engineer (Linux, Networking, Rust)

Our client is looking for an Software Engineer ControlOne. This role consists of designing, implementing, and optimizing 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.

As part of that commitment, we believe in providing clear information about how our hiring technologies work and how your data is used. The following section outlines our AI-assisted interview process and your rights as a candidate. 

AI-Assisted Interview Experience (Pete & Gabi – Rebecca):

To provide a consistent, fair, and flexible experience for all candidates, we use AI-assisted tools—including our proprietary platform Pete & Gabi – Rebecca—to support parts of the interview process. These tools help us:

• transcribe interviews,
• summarize candidate responses,
• generate job-related insights
• streamline communication and scheduling.

Please note that

• AI does NOT make hiring decisions.
• All decisions are made by our human recruiters, hiring managers, or client partners.
• The AI does not evaluate facial expressions, emotions, or physical traits.
• It is used only to support fairness, consistency, and efficiency.

If you prefer a non-AI interview format, we will gladly provide an alternative.

Technical or Case Interviews (Role-Dependent):

For certain positions, you may participate in:

• a technical interview
• a coding challenge
• a case study
• a client-specific assessment.

We will always explain what to expect in advance so you can prepare with confidence.

Human Review & Selection:

Every candidate’s profile—including interviews, conversations, and assessments—is reviewed by experienced recruiters and hiring leaders.

AI insights may assist with organization and evaluation, but final decisions are always human-driven.

Your Rights as a Candidate

At PTP, every candidate has the right to:

• Request a non-AI interview path
• Ask how your data is being used
• Request access to transcripts or interview recordings
• Request deletion of your AI-recorded interview
• Receive clear, timely communication

Our goal is to ensure you feel respected, informed, and supported throughout your experience
