• Develop application and traffic classification using signature based and ML assisted approaches

• Implement traffic shaping and QoS mechanisms such as hierarchical token bucket

• Integrate high performance pattern matching using Hyperscan

• Perform deep performance optimization using SIMD, cache tuning, and NUMA aware design

• Profile and debug performance bottlenecks using tools such as perf, VTune, or similar

• Work closely with hardware, infrastructure, and backend teams to ensure end to end system efficiency

Requirements

• 5+ years of hands on experience with DPDK in production systems, not research or prototypes

• Strong systems programming background in C++ or Rust, with willingness to work in Rust

• Deep understanding of poll mode drivers, mbufs, lockless data structures, and NUMA architectures

• Solid knowledge of TCP/IP stack internals and packet level protocol parsing

• Proven experience building and optimizing low latency, high throughput network systems

• Strong debugging and performance analysis skills

• Ability to work independently on complex, low level technical problems

• English level sufficient for technical discussions in an international engineering team

Nice to have

• Experience working at networking vendors or telecom equipment companies

• Background in carrier grade DPI systems

• Hands on experience with traffic shaping or QoS implementations

• Experience with ML inference pipelines such as ONNX Runtime

• Familiarity with eBPF, XDP, or kernel bypass techniques

• Experience with hardware offload technologies such as Flow Director or SR IO V

This is a long term opportunity to work on a technically extreme system at the core of a growing Canadian startup, solving hard performance problems at scale and building software that operates at the limits of modern networking hardware.

We are hiring a DevOps / Infrastructure Engineer for a Canadian product startup building a high performance intelligence and security platform.

• Implement monitoring, dashboards, and alerting using Prometheus and Grafana

• Manage ClickHouse operations including replication, partitioning, TTLs, and performance tuning

• Set up and maintain lab environments with physical servers, NICs, and traffic generators

• Troubleshoot networking and hardware issues in test and staging environments

• Collaborate with engineers to improve system reliability, scalability, and operational practices

Requirements

• 5+ years of hands on experience with Linux systems, including bare metal and containerized environments

• Strong production experience with Docker and Docker Compose

• Practical experience with Ansible or Terraform for infrastructure automation

• Solid knowledge of monitoring and observability stacks, including Prometheus and Grafana

• Experience building and maintaining CI/CD pipelines

• Good understanding of networking fundamentals such as VLANs, routing, and traffic flows

• Ability to work independently in complex infrastructure environments

• Conversational English level sufficient for daily communication with an international team

Nice to have

• Experience with Kubernetes in production environments

• Background in carrier grade, ISP, or telecom infrastructure

• Hands on experience with high performance networking or DPDK based systems

• Hardware level troubleshooting experience

This is a long term opportunity to work on a technically complex platform in a growing Canadian startup, with real world impact and deep infrastructure challenges.
