As a Senior Cloud Security Engineer at our company, you'll own the security controls customers actually trust us to ship. Every major cloud - AWS, Azure, GCP, OCI - gives you a partial set of our company controls, and none of them cover what an enterprise security team really needs. You'll close the gaps: research what each cloud exposes, design controls that produce a consistent security outcome across all of them, and tailor each one to the provider it runs on. You'll work end-to-end. Research, threat model, design, infrastructure-as-code, rollout, production validation. No handoffs, no thrown-over-the-wall designs
Key Responsibilities
As a Senior Cloud Security Engineer, you'll take full ownership of security controls - from concept to delivery.
You'll engage with customers, align with our strategic direction, and identify what you and the team should build next.
You'll ship MVPs directly in production with real customer environments, iterate quickly based on feedback, and ensure the long-term success of your work.
And yes - you'll also jump in as a Security Hero, helping customers understand what their cloud is doing and what to do about it.

As a Cybersecurity GRC Specialist at our innovative healthcare startup, you will own our information security program end to end. We are on a mission to bring the first Hybrid Drug to market: a groundbreaking therapeutic entity that integrates mobile apps with traditional medication. Operating at the intersection of digital health and pharma means security, privacy, and compliance are core to what we build - and you'll be the one making sure we get it right. If you're excited to shape and lead the security function of a growing company (rather than inherit one), read on

About the Role
This is a hands-on role with broad ownership. You'll act as our security lead, serving as the go-to person for all things governance, risk, and compliance - working directly with leadership, engineering, quality, and clinical teams. It's a great fit for someone with a few years of GRC experience who's ready to take on company-wide responsibility, not a traditional executive CISO position.

we are looking for a Lead Security Researcher.
You will lead security research. This is not a bug hunting role. Your job is to invent the approaches that become product capabilities: new ways to detect, triage, and remediate vulnerabilities using LLMs and program analysis, proven on real data before a customer ever sees them.
You own the path from idea to shipped capability. You form the hypothesis, build the proof of concept, measure whether it actually works, and partner with engineering until it is in the product. You also own the quality bar: the benchmarks and evaluations that decide whether what we ship is good enough to put in front of customers.
You will set the research agenda, not just execute one. As the team grows, you will shape how research works here.

We're looking for an experienced Security Researcher to join our core team and deep dive into CVEs, conducting cutting-edge vulnerability research that directly powers Echo's revolutionary approach to eliminating container vulnerabilities at the source.
Responsibilities:
Conduct deep-dive research into CVEs and vulnerabilities, analyzing root causes and attack vectors to inform our AI-powered prevention platform
Perform reverse engineering analysis using tools like IDA Pro, Ghidra, or similar platforms to understand complex security vulnerabilities and exploitation techniques
Research and analyze complex low-level system mechanisms including kernel vulnerabilities, network security issues, and operating system weaknesses
Think outside the box, challenge existing assumptions, and create innovative approaches to vulnerability research and prevention
Work in a unique environment where your research insights are rapidly implemented into our product, creating direct real-world impact from your vulnerability research
Contribute to Echo's technical knowledge base and help establish new methodologies for proactive vulnerability identification and mitigation

This is a full-time on-site role located in Haifa for a SecOps professional. The responsibilities include maintaining and optimizing security operations, identifying and mitigating potential vulnerabilities, implementing security monitoring solutions, and responding to security incidents. The role involves working collaboratively with cross-functional teams to ensure the deployment of robust security measures and policies across systems and infrastructures.

we are looking for a WAF Security Specialist.
What You'll Do:
Create - Produce production WAF rules across providers for high-impact CVEs and customer findings - driving the Copilot harness on most of them, writing the expression yourself on the hard ones (no public PoC, exploitable path reasoned out of a patch diff, urgent customer coverage). Your rules ship, and they set the bar generated rules are measured against.
**Optimize -**Tighten generated rules for real production constraints: WCU and rule-capacity budgets, latency, provider expression limits, and the anchoring required for a rule that fires against all traffic behind a shared Web ACL - not just the vulnerable app.
Validate - Own the adversarial pass. Build exploit variants the PoC doesn't cover, hunt bypasses in our own rules, and run the false-positive side seriously - verifying against how the legitimate client actually behaves on the wire, not against an assumption.
Monitor - Watch deployed rules in production: false-positive signals, hit patterns, coverage drift as managed rulesets shift underneath us, and the log→block promotion decision. Retire what no longer earns its capacity.
Make it reproducible - Turn every finding into a regression test. Build and curate the golden CVE datasets and scoring rubrics that gate whether a new Copilot version ships.
Set the coverage line. Judge which CVEs are genuinely WAF-mitigatable and which aren't, and make the call on what enters and leaves our managed rulesets - with the reasoning written down.
