Job Description

Senior Platform Engineer – DevOps, Infrastructure and Platform

OZmap

• Design, operate and evolve AWS (EC2) and on-premises environments with containers (Docker), ensuring availability, security and scalability; • Operate and administer Linux production environments (systemd, kernel/network tuning, I/O, process troubleshooting); • Build and evolve CI/CD pipelines from scratch, including quality and security gates; • Develop end-to-end observability (instrumentation, exporters, PromQL, SLI/SLO, alerts); • Lead advanced troubleshooting, root cause analysis and blameless post-mortems — driving structural change afterwards, not just producing a report; • Implement automation using Infrastructure as Code; • Analyze and optimize cloud costs: rightsizing, usage analysis and proposing data-driven alternatives; • Act as a technical reference for developers and engineers, influencing architecture without relying on formal authority.

Job Requirements

  • Required: production experience operating core primitives in AWS (~4+ years): EC2, VPC/networking, IAM and security — production operation and technical decision-making;
  • Linux and networking (~4+ years): server administration and production troubleshooting — disk full, OOM killer, network diagnostics; processes, memory and I/O;
  • CI/CD built from scratch (~3+ years): pipelines created and evolved by you (GitHub Actions, Jenkins, self-hosted runners, secrets, caching, gates);
  • End-to-end open-source observability (~2+ years): Prometheus, Grafana, Loki, VictoriaMetrics or equivalents — configured and operated by you, not just used. OpenTelemetry — including instrumentation, exporters, PromQL and SLI/SLO definition;
  • Operation under managed layers: concrete experience with nginx/HAProxy/Envoy, Linux underneath, and leading the resolution of critical incidents you have driven;
  • Docker in production (~3+ years): real operation of containers in critical environments — volumes, networking, resource management, graceful shutdown of services;
  • High autonomy: receives an ambiguous problem ("our observability is weak") and delivers end-to-end;
  • Ownership and proactivity: anticipates problems before they become incidents;
  • Clear communication and technical influence, connecting development, infrastructure and business teams;
  • Conducts post-mortems focused on root cause, organizational learning and continuous improvement, without a blame culture;
  • Maturity to self-manage while working remotely.

Benefits

  • 💻 Equipment allowance – to ensure a comfortable work setup;
  • 💚 Health support – because your well-being matters;
  • 📚 Education support – we support your continuous development journey;
  • 🎂 Birthday gift – because we like to celebrate together;
  • 🏅 Recognition for tenure – your time with us is valued;
  • 🗣️ Language support – to help you go beyond borders;
  • 🏋️ TotalPass (for employee use only);
  • 🌴 Paid leave after 12 months of employment;
  • 🎉 Online integration events and socials.

This role will work closely with engineering, architecture, and operations teams to improve multi-tenant deployment velocity, infrastructure scalability, platform observability, and rigid tenant isolation safety boundaries. Key Responsibilities - Design, configure, and manage high-availability AWS cloud infrastructure (VPC layouts spanning 3 AZs with segregated public, application, and data tiers) using Infrastructure-as-Code (IaC) best practices. - Build and maintain scalable CI/CD pipelines supporting automated multi-tenant deployment workflows and immutable release paths. - Configure and manage AWS networking, egress-only NAT gateways, private EKS API endpoints, identity/access management (CASL architecture), and environment configuration. - Support AWS deployment automation, logging, alerting, and operational readiness, explicitly monitoring threat vectors emitted to Amazon CloudWatch and CloudTrail. - Partner with engineering teams to optimize the velocity and stability of application onboarding cycles (e.g., standardizing patterns learned during the VELMA / Legal launch). - Troubleshoot complex infrastructure, deployment, cross-tier networking, and multi-tenant isolation configuration anomalies. - Support automated data protection operations, verifying 30-day credential rotations via AWS Secrets Manager and automated snapshots within an isolated AWS Backup vault. - Contribute to core platform standards, compiling detailed operational runbooks to convert tribal knowledge into repeatable assets. - Participate in agile ceremonies including standups, backlog refinement, and retrospectives. - Enforce security and compliance requirements (e.g., SOC2 metrics) across all staging, performance, and production environments. Qualifications - Extensive (5+ years) hands-on experience in engineering, scaling, and debugging enterprise AWS infrastructure platforms. - Deep expertise with AWS CDK, Terraform, or CloudFormation templates, with a mandatory emphasis on using CDK to maintain modular cloud architectures. - Advanced experience building and maintaining automated deployment code workflows (specifically via GitHub Actions). - Mastery across AWS services powering multi-tenant frameworks, explicitly including: Amazon Cognito (multi-pool structures), Amazon Aurora PostgreSQL, Redis/ElastiCache, Amazon S3, CloudFront/AWS WAF, CloudWatch, EventBridge/SQS/Step Functions, and AWS Secrets Manager. - Solid understanding of multi-tenant security strategies, policy-based access layers (RBAC/ABAC), and network boundary definitions. - Experience tracing and debugging errors across heavily decoupled cloud systems and microservices. Nice to Have Skills - Experience in engineering enterprise-scale multi-tenant SaaS cloud platform hosting models. - Experience supporting containerized and serverless AWS workloads, with emphasis on Amazon EKS on Fargate running inside isolated private subnets. - Prior exposure to developer enablement practices and building automated onboarding templates to abstract platform complexity. - Experience maintaining infrastructure inside tightly audited, regulated, or security-sensitive environments (SOC2 alignment). Soft Skills - The ability to understand the daily frustrations of application development teams and approach infrastructure as a service that enables—rather than blocks—their engineering velocity. - Maintains extreme clarity, calm focus, and structured communication during high-pressure platform outages or deployment rollbacks before escalating to Slalom’s Incident Command. - Possesses the open, friction-free communication style needed to pair directly with the Brazil team (OE) to absorb complex cloud infrastructure topologies and code patterns.
