Resilience Engineering III

Description

Hey, come meet Gobrax! Today we are the best company in Latin America in the management of connected fleets, and we want to become the best in the world. At Gobrax, we are driven by an obsession with the customer, we act with attitude, simplicity, and speed, always guided by data and the power of sharing. ✨ **Your mission at Gobrax:** We are forming a Chaos Engineering front within Gobrax engineering. The objective of this position is simple to describe and difficult to execute: break the production environment in a controlled manner, before it breaks on its own. You will design and execute chaos experiments, continuously monitor deployments and production platforms, investigate anomalies in tools like Datadog, and direct corrections to the right teams, before they become incidents visible to the customer. **Responsibilities** * Design, implement, and execute chaos engineering experiments in production and pre\-production (network failure, induced latency, kill of pods/instances, CPU/memory saturation, unavailability of dependencies), always with controlled blast radius and rollback plan. * Develop internal tools and frameworks in Go and Python to automate resilience testing (integrating or replacing solutions like Chaos Mesh, Litmus, or Gremlin). * Continuously monitor deployments, CI/CD pipelines, and production platforms, identifying anomalies and risks before they impact users. * Thoroughly investigate observability data (Datadog, logs, metrics, distributed traces) to find the root cause of performance and availability issues. * Direct and prioritize the problems found together with frontend, backend, AI, and DevOps teams, defining criticality and following up on resolution until closure. * Create and maintain runbooks, incident response playbooks, and disaster recovery plans. * Conduct blameless postmortems and retrospectives after incidents and experiments, disseminating learnings across engineering. * Define SLOs, SLIs, and error budgets in conjunction with Tech Leads and Team Leaders. * Mentor full-stack and junior developers in reliability, observability, and chaos engineering practices. * Act as a technical reference in architectural decisions related to resilience and fault tolerance. **Requirements** * 5\+ years of experience in backend development, with solid mastery of Go and Python in production environments. * Practical experience with chaos engineering (Chaos Mesh, Litmus, Gremlin, AWS Fault Injection Simulator, or proprietary tooling). * Mastery of observability: Datadog (or equivalent — New Relic, Grafana/Prometheus), APM, and distributed tracing. * Experience with Kubernetes, containers, and orchestration in high availability environments. * Deep knowledge of distributed systems and resilience patterns (circuit breaker, retry with backoff, bulkhead, timeout, idempotency). * Experience with public cloud (AWS, GCP, or Azure) and infrastructure as code (Terraform, Pulumi, or similar). * Proven track record of working in critical production environments, including incident management (on\-call). * Clear and assertive communication to direct technical problems to multiple teams and leadership levels. **Differentiators** * Certifications related to SRE or cloud (e.g., CKA, AWS/GCP Professional). * Previous experience in SRE, Platform Engineer, or Infra positions. * Open\-source contributions in chaos engineering or observability tools. **Gobrax Benefits** **Flexible Benefits — Caju** Flexible voucher \+ meal voucher on a single card. **Bonus for meeting goals.** **Health Plan — Unimed** Affordable monthly fee \+ copayment. **Dental Plan — DentalUni** Affordable monthly fee and extensive accredited network. **Transportation Voucher** *or* **Fuel Reimbursement** (option with 6% discount on payroll) **️‍ ️ WellHub (Gympass)** Access to the well\-being platform, gyms, and health services. **Zenklub** Emotional health platform, with psychological support and well\-being content. **️ SESC Agreement** Discounts and advantages in various units and services. **Gobrax Academy** Technical, behavioral, and leadership development tracks. **Extended maternity and paternity leave** **️ Life Insurance — MetLife** **Fresh fruits during working hours** **Happy Hour on Fridays** **Our Culture** At Gobrax, we are driven by an obsession with the customer, always seeking to generate value and delight, in a simple and efficient way.
