We are seeking a highly motivated and technically proficient Senior Penetration Tester to join our security research division. This role is dedicated to performing advanced offensive security assessments against the biggest companies in the world
You need to be independent, attentive to details, organized, eager to learn new things, and like to research and solve problems
What youll do:
Lead and execute comprehensive, technically rigorous penetration tests targeting complex web applications, modern API architectures, and enterprise systems for organizations with significant global presence.
Engage in sophisticated Red Team projects, including the identification of undisclosed API endpoints, development of novel bypass techniques for established security controls, and lateral movement within target environments.
Contribute substantively to the design, development, and maintenance of proprietary internal security tools and automation frameworks to enhance the efficacy and efficiency of offensive operations.

Were looking for a Principal Software Engineer to own the RL Gym platform end-to-end: from architecting multi-site web environments that simulate real-world attack surfaces, to optimizing our in-house orchestration harness (AgenticVerse) for high-performance delivery into customer training pipelines.
This is a builder role. Youll lead a small team (including a dedicated web environments engineer), operating with high autonomy, moving fast from concept to working prototype to production system. Youll interact directly with customer engineering teams to understand their infrastructure constraints and deliver environments that meet their scale and reliability requirements.
Why this role:
This is one of the few roles in the industry where your code directly influences how the next generation of AI models are trained. Youll be at the center of advancing AI safety, building systems that the worlds top labs depend on to make their models more robust. The work is technically deep, the problem space is genuinely novel, and the field is moving faster than any team can keep up with alone. Theres no playbook. Youll write it.
What youll do:
Platform & performance:
Own and evolve AgenticVerse, our in-house orchestration harness that provisions and manages RL environments at scale. Focus on performance: low-latency provisioning, high concurrency, minimal overhead per environment instance
Design and build isolated, reproducible web environments using Firecracker microVMs or Docker containers
Architect multi-site scenarios (3-4 interconnected web applications per task) with rich interactions: drag-and-drop, file uploads, authentication flows, LLM-in-the-loop components
Implement deterministic verifiers that evaluate agent behavior with zero ambiguity
Customer delivery:
Work directly with engineering teams at leading AI labs to integrate RL Gym environments into their training and evaluation pipelines
Translate customer specs into working environments, iterating rapidly on feedback
Own the technical relationship: SLAs, API contracts, integration architecture
Adapt environment delivery formats to cus tomer infrastructure (real-time API calls vs. offline batch, managed vs. raw artifacts)
Build customer-facing UIs when needed (dashboards, environment configuration portals, monitoring interfaces)
Rapid prototyping:
Take ambiguous problem descriptions and produce working prototypes within days, not weeks
Validate new environment types, interaction patterns, and verifier approaches quickly
Build internal tooling that accelerates scenario authoring and testing.

Required HR Business Partner
Description
Youll serve as a strategic advisor to managers and leaders, aligning people strategies with business objectives. Youll act as a trusted consultant, helping leaders build high-performing teams, make data-driven people decisions, and foster a culture that supports our mission and goals.
This is a hybrid position; youll be asked to be in our office in Ramat Gan three times per week.
Key Responsibilities:
Partner with managers and leaders to align people strategies with business objectives and organizational priorities.
Use people analytics and workforce data to identify trends, inform decisions, and address organizational risks and opportunities.
Drive talent management initiatives, including workforce planning, succession planning, retention, and leadership development.
Partner with Talent Acquisition and hiring managers to support hiring plans, organizational growth, and critical talent needs.
Coach managers on performance management, employee relations, leadership effectiveness, and team development.
Support employee engagement, culture, and organizational effectiveness initiatives, including survey analysis and action planning.
Partner with leaders to manage organizational change, restructures, and transformation initiatives.
Advise on compensation, promotions, policy interpretation, compliance, and other people-related matters to ensure consistent and effective people practices.

We are hiring a Senior Software Developer to lead the development of our internal malware research platform. This is a senior, hands-on role with end-to-end ownership of development and delivery. You'll be the technical authority - setting code-quality standards, making the architecture calls, and mentoring the developer team.
What makes this role different is who you build for. Our users are our malware researchers, and they use the tool every day. Your job is to sit beside them, learn how they actually work, surface the heuristics and edge cases they carry in their heads, and build agentic tooling that compounds their productivity. The bar isn't "does it ship" - it's "do the researchers reach for it every day." Success is measured in researcher adoption and time saved, not features merged.
Agentic workflows are core to how we build. You should be fluent using them and confident designing systems where agents run in production - with clear judgment about where an agent earns its keep versus where deterministic code or a human-in-the-loop is the right call.
What You'll Do
Lead development and deliveryף
Own technical execution end-to-end: implementation, code review, and release.
Translate research workflows and feature requests into well-scoped tasks with realistic, risk-aware estimates the team can plan against.
Manage day-to-day execution: unblock people, sequence work, catch problems early.
Set and defend the technical bar: review rigor, testing discipline, documentation, architectural consistency.
Partner with the researchers - and amplify them:
Embed with malware researchers to understand their workflow and capture the tacit knowledge and edge cases no spec ever wrote down.
Translate that knowledge into reliable agentic tooling - and know when an agent is confidently wrong before it ever reaches a researcher.
Spend roughly 5-10% of your time doing actual malware research (with structured onboarding) to stay close to how the tool is used.
Be willing to tell a researcher when a proposed workflow won't automate well - and explain why.
Be the technical authority and mentor:
Make the hard architecture and design trade-off calls.
Mentor through code review, pairing, and design discussions. Raise the level of everyone around you.
Dive deep on the critical, difficult features and bug fixes yourself.
Design agentic workflows into the architecture from the start, and build the evaluations and guardrails that keep them trustworthy.
