Обязанности
- You will own outcomes, not a queue. You'll lead workstreams across the security function, pair with and mentor early-career engineers, and be trusted to make calls without waiting for sign-off.
Требования
- 2–4 years in security engineering, cloud security, application security or a closely related engineering role, including hands-on production experience
- Strong, practical knowledge of AWS and/or GCP security: IAM design, network controls, logging and detection, and the ability to read and write infrastructure as code (Terraform or similar)
- Solid programming ability in at least one language (Python, Go, JavaScript/TypeScript): you build tooling and automation, not just review other people's code
- Real secure-code experience: you can find and explain injection, auth/authz, secrets handling and supply-chain issues in code and in CI/CD pipelines, and you know how to get developers to fix them
- Hands-on experience with a SIEM (Splunk preferred) and an EDR platform, including detection engineering and investigation
- Working understanding of LLM-based systems and agents, including their failure modes, and experience using or building with them in a technical setting
- Sound judgment on risk: you know the difference between a finding that blocks a launch and one that ships with a follow-up, and you can defend that call
- Strong written and spoken communication in Spanish and English; you can explain a risk to an engineer, a product manager and an auditor in the same week
- Comfort with pace and ambiguity: priorities move, the stack evolves, and you'd rather build the process than wait for it
Будет плюсом
- Experience in fintech, payments or another regulated environment (PCI DSS, ISO 27001, SOC 2)
- Experience securing or red-teaming LLM applications, agents or MCP tooling
- Kubernetes and container security
- Detection-as-code, SOAR or security automation experience
- Certifications such as AWS Security Specialty, Google Professional Cloud Security Engineer, OSCP, GIAC or CISSP
- Portuguese
- Contributions to open source, conference talks or CTF/bug bounty track record

- Define and operate the controls for how uses LLMs, coding agents, agentic browsers, MCP integrations and internal inference gateways: data handling, identity, permissions, logging
- Own the LLM-based investigation agent on the SIEM: design its instructions and rules, evaluate its accuracy, catch hallucinated attributions and unsupported conclusions, and decide what it is allowed to close autonomously
- Threat-model AI systems as first-class attack surface: prompt injection, data exfiltration through AI tools, over-privileged agents, model and tool supply chain
- Build the guidance and paved paths that let product and engineering adopt AI safely by default, and be a credible voice in those decisions
- Own detection and posture across AWS (GuardDuty, IAM, VPC, CloudTrail) and GCP (Security Command Center, IAM, service accounts, org policies), and drive remediation with the owning teams
- Design and implement guardrails as code: organization policies, SCPs, IAM boundaries, infrastructure-as-code policy checks
- Lead parts of our large-scale GCP project inventory and cleanup program, and turn one-off findings into automated controls
- Secure identity and edge: Auth0, Cloudflare, Google Workspace, SSO and service-to-service authentication
- Run and evolve the application security program: SAST (SonarQube, Semgrep or similar), dependency and secrets scanning, PR review for security-sensitive changes, and CI/CD pipeline hardening
- Review architecture and code for new products and integrations (card issuing, payments, banking partners) and produce actionable, prioritized findings
- Define secure-by-default patterns and libraries for engineers, including for AI-generated code, and measure whether they're being used
- Coordinate pentests and vulnerability disclosure, and drive findings to closure
- Build and tune detections in Splunk across identity/SSO, cloud, endpoint, email and network sources, with a bias toward high-signal alerts
- Lead incident investigation and response through: scoping, containment (EDR isolation, credential revocation, cloud access), root cause and post-incident review
- Own email and web protection policy and the phishing program
- Mentor early-career engineers on investigation technique and evidence-based reporting, and review their work
- Map your controls to PCI DSS and ISO 27001 requirements, and produce the evidence auditors need without slowing the team down
- Support customer security reviews and enterprise sales when a technical voice is needed
- Ownership of problems that matter at a unicorn fintech, with direct exposure to leadership and to the decisions that shape how adopts AI
- Frontier work: securing agentic AI in production, in a company that is actually deploying it
- A modern stack and the mandate to improve it: AWS, GCP, Splunk, Auth0, Cloudflare, SonarQube,, Claude and internal AI tooling
- A team that values evidence over hierarchy, and expects you to push back when the data doesn't hold
- Budget and time for certifications, conferences and the hacker community
- Fast, transparent hiring: application review, a technical deep-dive on real scenarios you've handled, a practical exercise, and conversations with the team and leadership
- Tell us about a control you designed that made engineers faster, not slower. Or an incident you led, a detection you built, a vulnerability you found, or something you've published. We care about how you think about risk and how you get things fixed, not about the length of your tool list.
- #Clarity. We say things clearly, directly, and proactively.
- #Simplicity. We reduce noise to focus on what really matters.
- #Ownership. We take responsibility and never wait to be told.
- #Pride. We build products and experiences we’re proud of.
- #Always Be Changing (ABC). We grow through feedback, risk-taking, and action.
- #Inclusivity. Every voice counts. Everyone contributes to our mission.
- Claridians in a hybrid mode split their time between working from the office, talking to or visiting customers, or working from home. This hits a balance between bringing people together for in-person collaboration and learning from each other, while supporting flexibility about how to do this in a way that makes sense for each individual and team.
- We don't enforce a minimum number of days for most roles, but you're expected to spend time at the office organically, and be at the office most days during your ramp-up or when required by your leader.
