Job Description – Endpoint Software Developer

Overview

We are seeking an experienced Endpoint Software Developer to design and build high-performance, low-overhead client software for Windows, macOS, and Linux environments. The ideal candidate has deep systems-level expertise, strong networking fundamentals, and hands-on experience working with modern endpoint technologies including eBPF, transparent proxies, and advanced packet inspection.

Key Responsibilities

  • Design, develop, and optimize endpoint agents
    for Windows, macOS, and Linux that monitor system behavior, enforce policies, and enable secure communication with backend services.
  • Leverage eBPF to build high-performance Linux endpoint components
    , including kernel-level monitoring, packet filtering, telemetry generation, and lightweight traffic inspection.
  • Implement robust networking features
    within the endpoint—covering TCP/IP, SSL/TLS, HTTPS, SSE, WebSocket, and gRPC—to ensure secure and efficient data transfer.
  • Build and maintain transparent proxy components
    to intercept, inspect, and route traffic without degrading system performance.
  • Perform deep packet inspection (DPI)
    to identify patterns, enforce rules, or extract relevant metadata for security or analytics use cases.
  • Implement and tune load balancing and SSL handling mechanisms
    , ensuring reliability and scalability across diverse device types and environments.
  • Collaborate with platform, backend, and security teams
    to define data models, optimize communication flows, and integrate endpoint capabilities with cloud services.
  • Conduct rigorous profiling, optimization, and debugging
    at both the kernel and user-space levels to ensure stability, reliability, and minimal resource consumption.
  • Maintain strong code quality
    through thorough documentation, automated testing, CI/CD integration, and adherence to secure development practices.

Required Skills & Qualifications

  • Strong proficiency in systems-level programming
    (C/C++, Rust, or Go).
  • Deep experience building Windows and macOS endpoint software
    , including drivers, services, background daemons, or low-level agents.
  • Hands-on experience with Linux internals
    and expertise in
    eBPF
    , XDP, or kernel networking subsystems.
  • Strong understanding of core networking protocols:
  • TCP/IP, DNS, SSL/TLS, HTTPS
  • SSE, WebSocket, gRPC
  • Experience with traffic interception and inspection
    , including DPI and transparent proxy architectures.
  • Knowledge of load balancing algorithms
    , SSL offloading/termination, and certificate management.
  • Familiarity with
    sandboxing, endpoint security
    , or malware detection concepts is a plus.
  • Experience with
    performance profiling tools
    (e.g., perf, Wireshark, Sysinternals, Instruments).
  • Experience with
    cross-platform development
    and building installers, updaters, or system extensions.
  • Strong debugging skills, problem-solving capability, and attention to detail.

Preferred (Good to Have)

  • Experience with
    endpoint security products
    (EDR/XDR/AV).
  • Experience with
    virtual networking
    , TUN/TAP devices, or user-space networking stacks.
  • Knowledge of
    Zero Trust Networking
    , policy enforcement, and identity-aware traffic routing.
  • Familiarity with cloud platforms (AWS/GCP/Azure) for agent-backend integrations.
