      <title>Principal Software Engineer I - CI/CD - Platform Engineering Productivity</title>
      <description><![CDATA[<p>Elastic, the Search AI Company, enables everyone to find the answers they need in real time, using all their data, at scale , unleashing the potential of businesses and people.</p>
<p>The Platform Engineering Productivity team operates the CI, CD, and Release infrastructure for the company. We ensure developers can efficiently and safely deploy changes across our various environments and at scale. In an age of AI, the landscape is evolving rapidly from scaling needs to, more than ever, securing our supply chain.</p>
<p>We&#39;re looking for a proactive systems thinker who delivers on business-driven projects while identifying and driving the work that keeps our infrastructure ahead before scaling and security challenges become problems.</p>
<p><strong>Responsibilities</strong></p>
<ul>
<li>Define the roadmap and technical vision for CI/CD, from problem identification through org-wide adoption.</li>
<li>Identify where CI/CD is a bottleneck, a source of friction, or a security risk before it becomes an incident, and drive the remediation rather than waiting to be assigned it.</li>
<li>Design and enforce release gates covering supply chain integrity, artifact provenance, and release readiness, built to scale across teams without becoming a tax on engineering velocity.</li>
<li>Direct engineers on your team through complex, multi-quarter projects: break down the architecture, assign the work, and own the outcome even when the execution is distributed.</li>
<li>Drive clear technical communication and alignment across teams, and produce high-quality documentation for systems, processes, and architectural decisions.</li>
<li>Serve as Incident Commander on high-severity supply chain or release incidents, and use each incident as a forcing function for structural improvements.</li>
<li>Raise the engineering bar across the org through code review, mentorship, design review, and by setting standards others adopt voluntarily.</li>
<li>Remain hands-on at the right depth: you&#39;ll review code, prototype approaches, and debug production issues, but your primary leverage at this level is through the work of others, not your own output.</li>
</ul>
<p><strong>Requirements</strong></p>
<ul>
<li>Deep expertise in CI/CD and what it takes to harden a release pipeline against supply chain attacks.</li>
<li>Strong debugging instincts across the full pipeline stack: you trace failures from test runner to artifact store to cluster deployment without needing a specialist for each layer.</li>
<li>Hands-on with CI infrastructure (Buildkite, GitHub Actions, or equivalent), GitOps/ArgoCD, and Kubernetes.</li>
<li>You use AI to accelerate your own work and your team&#39;s and you understand AI&#39;s impact on supply chain security and scale.</li>
<li>A track record of multi-quarter, cross-org ownership: you&#39;ve identified the right problem, designed the solution, and gotten organizations that didn&#39;t report to you to change how they work.</li>
<li>The judgment to push back on a prescribed plan when it&#39;s the wrong call, and the credibility to get alignment on a better approach.</li>
<li>Experience directing the work of other engineers toward outcomes not just collaborating, but breaking down complex problems into executable work and holding the outcome.</li>
</ul>
<p><strong>Compensation and Benefits</strong></p>
<p>The typical starting salary range for this role is: 369,400 zł - 584,300 zł PLN Competitive pay based on the work you do here and not your previous salary Health coverage for you and your family in many locations Ability to craft your calendar with flexible locations and schedules for many roles Generous number of vacation days each year Increase your impact - We match up to $2000 (or local currency equivalent) for financial donations and service Up to 40 hours each year to use toward volunteer projects you love Embracing parenthood with minimum of 16 weeks of parental leave</p>

      <description><![CDATA[<p>Elastic, the Search AI Company, enables everyone to find the answers they need in real time, using all their data, at scale , unleashing the potential of businesses and people.</p>
<p>The Context Engine team builds the knowledge layer that AI agents use to work with enterprise data in Elasticsearch. As a Principal AI Engineer, you own the improvement loop of this product end to end: how agents, automations and skills behave in production, how we observe them, how we evaluate them, and how we ship changes to them safely.</p>
<p><strong>Responsibilities</strong></p>
<ul>
<li>Own the production improvement loop for Context Engine: understand how extraction automations, retrieval tools and memory behave, based on offline evaluations and customer conversations and telemetry.</li>
<li>Define how we iterate on agents and skills safely: versioning and rollout of prompts, skills and automations, regression coverage, staged and shadow evaluation, and the guardrails that let us change behaviour without breaking customers.</li>
<li>Design the telemetry we need to make data-informed engineering decisions: what to capture from agent traces, tool calls and knowledge retrieval, how it lands in Elasticsearch, and how it feeds evaluation, dashboards and the feedback loop.</li>
<li>Partner with the data science team on evaluation strategy: golden datasets, evaluators to gate on quality, latency and cost.</li>
<li>Raise the bar across the team: review designs and PRs, mentor engineers in eval-driven development, and write the technical proposals that shape the roadmap.</li>
</ul>
<p><strong>Requirements</strong></p>
<ul>
<li>10+ years of software engineering experience, with the recent years spent shipping and operating AI-driven products on real production traffic.</li>
<li>A track record of eval-driven product improvement: you have diagnosed agent or LLM behaviour from traces and user feedback, designed the evaluation that exposed the problem, shipped the fix and measured the outcome.</li>
<li>Direct experience building agents with state and memory, and iterating on prompts, skills and tool behaviour safely in production.</li>
<li>Familiarity with MCP, including exposing public MCP servers and tools.</li>
<li>Experience designing telemetry for AI systems, and using it to make engineering and product decisions.</li>
<li>Strong backend engineering skills in either Python or TypeScript: APIs, stateful workflows, data pipelines and production services.</li>
<li>Comfort working with data scientists, engineers, and product managers as peers, translating between measurement and shipping, and communicating trade-offs clearly.</li>
</ul>
<p><strong>Nice to Have</strong></p>
<ul>
<li>Experience with agent frameworks such as LangGraph, CrewAI, Claude Agent SDK, or similar.</li>
<li>Agentic retrieval experience, including knowledge representation.</li>
<li>Practical Elasticsearch experience.</li>
</ul>
<p><strong>Compensation</strong></p>
<p>The typical starting salary range for this role is: 369 400 zł-584 300 zł PLN</p>

      <title>Principal Product Manager - Identity Threat Detection &amp; Response</title>
      <description><![CDATA[<p>Elastic, the Search AI Company, enables everyone to find the answers they need in real time, using all their data, at scale , unleashing the potential of businesses and people.</p>
<p>We&#39;re looking for a Principal Product Manager to guide the vision, strategy, and execution for Identity Threat Detection and Response (ITDR) within Elastic Security. Attackers not only break in - they log in. Identity is now a major target for attacks. These attacks can happen in on-premises setups, cloud environments, or with self-directed agents. Detecting and responding to identity-based attacks is essential for any modern Security Operations Center (SOC).</p>
<p>In this high-impact role, you will define how Elastic detects, investigates, and responds to identity-based threats, building on our Entity Analytics and Entity Store foundation to deliver a credible, differentiated ITDR function. You will also own the roadmap for securing non-human and AI agent identities within Elastic Security, one of the fastest-growing and least-governed attack surfaces in the enterprise. You will work at the intersection of identity, detection engineering, and AI, partnering with threat researchers, data scientists, and engineers, and evangelizing our approach to a global community of security practitioners.</p>
<p><strong>Responsibilities</strong></p>
<ul>
<li>Define and own the vision, strategy, and roadmap for a credible ITDR function within Elastic Security, evolving our Entity Analytics and Entity Store foundation from behavioral analytics into an identity-defense outcome.</li>
<li>Manage the plan for non-human and AI agent identities in Elastic Security. This involves modeling service accounts, workloads, secrets, and self-directed agents as important identities. Each identity will have its own behavior standards, ownership, and lifecycle. You will also establish how to detect identities that operate continuously and at machine scale.</li>
<li>Work with threat research and detection engineering. Focus on identity-specific threats. These threats include credential access, privilege escalation, and identity-based lateral movement. They also involve the abuse of identity providers and tokens. Ensure that these threats relate to real-world adversary tactics.</li>
<li>Drive the response and containment strategy. This is the &#39;R&#39; in ITDR. Turn detections into action. Use identity-system integrations and automated responses. Make sure there is human oversight for important actions.</li>
<li>Work closely with our enterprise customers. Collaborate with security operations teams, sales, and solution architects. Your goal is to understand the requirements for identity attacks. You will also discuss priorities and clarify product needs.</li>
<li>Work with the design team to develop investigation and response experiences. These experiences will emphasize identity in the analyst workflow. Integrate identity signals with endpoint, cloud, and network data in the SIEM and XDR functions of our security operations platform.</li>
<li>Gain deep knowledge of the identity-security market. Know its major trends and the changing threat landscape. Use this information to develop a unique strategy and engage with analysts.</li>
<li>Be the product expert and evangelize Elastic&#39;s identity capabilities through content such as blog posts, talks, and open community interaction.</li>
</ul>
<p><strong>Requirements</strong></p>
<ul>
<li>Extensive Experience: 10+ years of experience in product management or solution delivery for security products such as SIEM, XDR, EDR, identity security, or detection and response. A consistent record of leading sophisticated, data-intensive products from inception through launch and iterative growth.</li>
<li>Identity Security Depth: A solid knowledge of identity-based attack techniques and the identity fabric. This includes Active Directory, cloud identity providers, SSO, OAuth, and privileged access. It also involves knowing how identity threats can occur in both on-premises and cloud environments. Knowledge of ITDR as a discipline and with entity behavioral analytics (UEBA).</li>
<li>You need to be fluent in non-human identities. This includes service accounts, workloads, secrets, and AI agents. You should also understand why traditional human-identity rules don&#39;t apply to identities that act independently and continuously.</li>
<li>AI and ML Fluency: Deep technical comprehension of the AI/ML landscape, including behavioral analytics, anomaly detection, LLMs, and agentic systems. You are comfortable working closely with data scientists and engineers, and you treat AI agents both as a subject to be secured and as a tool that consumes identity context.</li>
<li>Bias to action: You are able to advance fast and quickly learn from experiments and tests. You utilize AI tools to help accelerate your processes and bring clarity to your decisions.</li>
<li>Management and Influence: Demonstrated ability to lead across a matrixed organization, align multiple stakeholders toward a common vision, and drive execution in a dynamic, remote-first environment. You operate with the autonomy and judgment expected of a principal-level product leader.</li>
<li>Communication Excellence: Outstanding spoken and written communication skills and practices. You can distill complex detection engineering and identity concepts into compelling narratives for both technical and non-technical audiences, including executive leadership.</li>
<li>Customer Obsession: An interest for industry trends and a commitment to solving real-world customer problems. You are an advocate for the security analyst and detection engineer, and you are focused on building products that help defenders stay ahead of identity-based threats.</li>
</ul>
<p><strong>Benefits</strong></p>
<ul>
<li>Competitive pay based on the work you do here and not your previous salary</li>
<li>Health coverage for you and your family in many locations</li>
<li>Ability to craft your calendar with flexible locations and schedules for many roles</li>
<li>Generous number of vacation days each year</li>
<li>Increase your impact - We match up to $2000 (or local currency equivalent) for financial donations and service</li>
<li>Up to 40 hours each year to use toward volunteer projects you love</li>
<li>Embracing parenthood with minimum of 16 weeks of parental leave</li>
