Tetragon Software Engineering Technical Leader
Job Description
Your Impact:
Tetragon is a flexible, Kubernetes-aware observability and security tool that delivers real-time insights and enforcement. Leveraging the power of eBPF, Tetragon provides low-overhead, in-kernel visibility and intelligence across diverse environments.
As a Technical Leader, you will be at the forefront of advancing Tetragons capabilities. You will guide architectural direction while staying deeply engaged in building the systems that power our platform. Your impact will span designing high-performance data pipelines, optimizing database and distributed system performance, and ensuring massive streams of system events can be ingested, aggregated, and distilled into meaningful intelligence.
You will collaborate closely with teams across, including Hypershield and Splunk, to create the integration points that transform raw data into actionable insights for enterprise security. In this role, youll solve some of the most complex system-level challenges in observability and infrastructure, helping Tetragon evolve to meet the needs of modern cloud-native environments.
What youll do:
Develop high-quality Go (and eBPF) code for the Tetragon project.
Design and implement new Tetragon features to enhance its capabilities for Runtime security detection and enforcement
Design and optimize systems for large-scale Tetragon deployment and operation in K8s or VM platforms
Architect infrastructure that converts raw event data into intelligence streams with minimal performance overhead.
Contribute to open-source projects and represent us in community discussions.
Participate in architecture reviews, code reviews, and documentation.

We are looking for a highly motivated and customer-focused professional. As part of the Tier 3 Cortex XDR support team, you will serve our customer base by providing technical support, by answering incoming support inquiries and managing escalations, phone calls, and emails in an effective, efficient, and friendly manner within defined service level agreements.
Our methodology is first class support. Weve been recognized for it as an industry leader and were dedicated to continuing this standard. In this role, you will work with our technical account managers to personalize our customers experience. You will learn your clients business objectives in and out within their technical environment and focus on mitigating risks and resolving any technical issues in their networks. Youre close to the deployment of cybersecurity solutions - and we need you to recognize risks before they arise. You get a thrill from seeking out complex issues and finding their resolutions - and you dont wait for those issues to escalate from our clients. Instead, you find them. Youll be working hand in hand with our developers to reproduce the issues you find and develop permanent solutions to prevent them in the future.
Key Responsibilities
Respond to customer-reported issues in adherence to established Service Level Agreements
Triage customer reported issues and respond to them via ticketing system, phone, or remote sessions
Perform advanced troubleshooting at the application level and OS level, using your knowledge and relevant expertise
Identify the area of fault (code, environment, or configuration) and work with the appropriate team(s), characterizing and implementing the fix
Provide timely feedback on the development process on customer-reported product problems
Document actions to effectively communicate information internally and to customers
Facilitate root cause investigations and manage the implementation of corrective and preventative measures.

We are seeking PHY Algorithm Technical Leader, Silicon One Israel
Meet the Team:
You will join the SerDes System Algorithm team within Silicon One High Speed in Israel, part of our silicon development organization. The team works across modem technology, system modeling, and signal processing for high-speed SerDes devices.
We are at the center of our ASIC group, building next-generation network devices for AI networks, the 5G era, and the future of routing. Our design center brings silicon hardware and software disciplines together in one site, combining a small-team startup atmosphere with the scale and stability.
Your Impact:
As a PHY Algorithm Technical Leader, you will provide technical leadership for the development, modeling, configuration, and optimization of algorithms for advanced SerDes modem systems. You will work with the latest silicon technologies and processes to help build large-scale, complex devices at the edge of feasibility.
Your work will contribute to Silicon One, a unified and programmable silicon architecture designed for service provider and web-scale markets. The role requires technical depth in digital signal processing, modem behavior, and using MATLAB for algorithm development, with the ability to guide algorithm work from initial concept through advanced SerDes system implementation.
Provide technical leadership for research, design, and development of PHY and modem algorithms for high-speed SerDes devices.
Define and use system models to analyze modem behavior, signal-processing performance, architecture constraints, and algorithm tradeoffs.
Guide modem configuration, tuning, and optimization to improve performance, robustness, and implementation feasibility.
Use MATLAB for algorithm development, simulation, testing, and data analysis.
Guide technical decisions, review algorithm tradeoffs, and mentor engineers on complex PHY and modem development tasks.
Lead cross-functional technical collaboration with system, silicon hardware, and software teams to move algorithms from modeling into practical implementation.
Support lab-based validation and debug activities when required.

We are seeking a skilled and experienced Software Engineer to develop a Go-based control plane within Kubernetes, with a focus on traffic security. You will be responsible for building and enhancing a Kubernetes-native control plane to provide seamless management of our eBPF datapath, enabling a secure traffic management in cloud and hybrid enterprise environments. You will work with a highly collaborative and skilled team to build solutions that advance the next generation of networking and security in Kubernetes environments.
Design and develop a Go-based control plane managing our enterprise-grade traffic security engine.
Develop APIs, tools, and custom resources to streamline secure traffic management, scaling, and failover within Kubernetes environments.
Debug, troubleshoot, and resolve performance, reliability, and security issues in the control and dataplane.
Participate in code reviews, architectural discussions, and contribute to technical documentation.

Required Tetragon Threat Detection Engineer - Isovalent
Job Description
About this role:
Cilium Tetragon is a flexible, Kubernetes-aware security tool, with real-time observability and enforcement. Leveraging the power of eBPF, Tetragon offers a low-overhead, in kernel solution that enhances security posture by monitoring system behaviors such as process executions, system call activities, and both network and file access events.
Tetragon Threat Detection Engineers primarily focus on creating and maintaining
Tetragon runtime security policies, based on the latest threat intelligence, vulnerability disclosures, and their own research.
Policies can act either as a mitigation to known vulnerabilities or as monitoring and protection against unknown security issues.
What youll do:
Develop and maintain Tetragon runtime security policies to ensure customers have good visibility of suspicious activity on their infrastructure and are protected against the latest emerging threats
Help design frameworks and architectures that allow customers to easily consume policies and understand their overall security posture
Monitor vulnerability disclosures (CVEs) and the latest threat intelligence to develop Tetragon runtime security policies
Work with software engineers at Isovalent and us to improve and enhance the capabilities of Tetragon security policies
Interact with solution architects and customers as necessary to support and deploy Tetragon security policies in production
Publish content and give talks based on your work.
