We are seeking an experienced and passionate Linux Kernel Developer to join our EDR/XDR Agent/Sensor Development Team. The ideal candidate will have a minimum 6+ years of deep expertise in Linux internals, Linux Kernel Module (LKM) development, C/C++ programming, and a strong understanding of container technologies. You will be part of the EDR/XDR agent/sensor development team, responsible for building core components of our EDR/XDR agent/sensor that operates in both user-space and kernel-space, focusing on system monitoring, threat detection, and remediation within Linux environments, including containerised workloads.
What You’ll Do At Cyble
- Work alongside our senior lead kernel developers to design, develop, and maintain Linux Kernel Modules (LKMs) for various EDR/XDR modules.
- Write LKMs for device management capabilities like USB and Bluetooth device controls within Linux environments.
- Develop user-mode services that interface with kernel modules for event processing, policy enforcement, and interaction with container runtimes.
- Implement real-time remediation actions such as process termination, file deletion/quarantining, and system snapshot/restore functionalities.
- Debug and resolve kernel panics, race conditions, memory leaks, and performance bottlenecks in kernel and user-space components.
- Develop and enhance monitoring capabilities for containerized environments (e.g., Docker, Kubernetes), understanding interactions between the host and containers, and leveraging kernel features like namespaces and cgroups.
- Integrate with backend admin consoles using various integration methods and data exchange formats like JSON and Protobuf.
- Integrate with Threat Intelligence Systems and other downstream components.
-
Collaborate with cross-functional teams (security analysts, product managers, QA) to translate detection use cases into scalable agent capabilities for Linux and container environments.
- Strong proficiency in C and C++, including multithreading and synchronization primitives.
- Deep knowledge of Linux OS internals (e.g., process management, memory management, VFS, system call interface, scheduling, namespaces, cgroups).
- Experience in developing Linux Kernel Modules (LKMs); familiarity with frameworks like eBPF, kprobes, tracepoints, or Linux Security Modules (LSMs) is a plus.
- Strong understanding of Linux security architecture, process/thread management, file system architecture, and inter-process communication.
- Solid understanding of container technologies (e.g., Docker, Kubernetes, containerd, CRI-O) and their underlying kernel primitives.
- Experience in developing security solutions for containerized environments, including monitoring container activity and host-container interactions.
- Familiarity with monitoring frameworks and tools in Linux (e.g., Auditd, perf, ftrace, SystemTap).
- Hands-on experience implementing kernel hooks and callback mechanisms; strong experience in writing user-mode code interacting with kernel components.
- Experience writing components that perform YARA rule lookups.
- Experience with kernel telemetry pipelines (e.g., using eBPF, Auditd, or custom solutions).
- Proven experience writing kernel/user-mode hooks for events such as process creation/execution, library loading, file system changes, network activity, and device access (e.g., USB, Bluetooth).
- Proficiency in building remediation components for various threat categories.
- Familiarity with Linux debugging tools (e.g., GDB, KGDB, crash, ftrace, perf) and analyzing kernel panic dumps.
-
Understanding of endpoint security concepts, including EDR/XDR product behavior.
- A dynamic and collaborative work environment.
- Opportunities for learning and career growth.
-
Mentorship from experienced developers to guide you in advancing your skills.

Senior Embedded Software Engineer
@ Embedd 
What we're looking for
At embedd.it, we power hardware-software integration in embedded devices. We turn fragmented semiconductor chip data into configurable digital twins, then deterministically generate code, tests, and documentation – making integration faster, cheaper, and resilient to supply chain shocks.
We’re looking for a true legend – someone with abstract thinking and deep expertise in low-level software development. You’ll build vendor-agnostic tooling for MCU and peripheral integration to solve hardware-software integration once and for all. We work at the intersection of embedded systems, code generation, compilers, and machine learning. It’s your chance to help redefine how low-level development is done.
Responsibilities
- Drive the architecture of the driver structures and system layout
- Define scalable patterns for cross-architectural integration across bare-metal, Zephyr, Linux, and other environments
- Deconstruct complex SoC device trees and translate hardware descriptions into structured internal models for automated reasoning
- Partner with the ML team to shape data and annotation models for AI-driven data-extraction tooling
Qualifications
- 5+ years of experience in embedded systems development, including bare-metal and RTOS-based systems
- Proficiency in C/C++
- Familiarity with firmware configuration, SoC bring-up, and system-level debugging
- Hands-on experience with code generation tools, or low-level compiler/decompiler/emulator technologies
- Strong background in embedded toolchains: compilers, linkers, debuggers, and build systems
- Python or scripting for automation and tooling is a plus
- Experience with functional-safety standards is a plus
Why embedd.it?
- Dynamic, venture-backed team of engineers challenging the status quo 🚀
- Work at the intersection of embedded systems, code generators, compilers, and ML 🤖
- Unusual challenges requiring out-of-the-box abstract thinking 🧠
- Competitive compensation: cash + equity 💰
- Remote work possible 🌍
About Us
embedd.it is a UK-based startup reinventing embedded development. Our platform transforms unstructured semiconductor data into structured digital twins, enabling automatic generation of drivers, tests, and documentation. We're building a single, traceable source of truth to make integration fast, vendor-agnostic, and future-proof.
