Senior Platform Engineer

Role Description

• Architectural Strategy: Define and steer medium and long-term architectural strategies for the platform, ensuring efficiency, scalability, and reliability across all AWS environments.
• Platform as a Product: Codify architecture into practice by delivering reference implementations and Golden Path templates for high-performance builds and standardized scaffolding.
• GitOps & Continuous Delivery: Engineer safe delivery and reusable GitHub Actions. Institutionalize GitOps using ArgoCD/Flux and Flagger for progressive rollouts (canary/blue-green) with automated, SLO-gated rollbacks.
• Cloud-Native Orchestration: Manage and optimize Kubernetes operations using Karpenter for intelligent node provisioning, as well as HPA and KEDA for event-driven autoscaling.
• Observability & SRE: Make observability the default through OpenTelemetry and New Relic. Define SLIs/SLOs, establish error-budget policies, and automate tracking of post-incident actions.
• Security & Service Mesh: Raise cloud and service security, operate and propose improvements related to OAuth2/JWT and secrets lifecycle management (Secrets Manager/KMS). Implement Policy-as-Code adoption across CI/CD and Kubernetes admission controllers.
• Event-Driven Excellence: Design and operate event topologies covering Kafka partitioning, compaction, retention policies, and schema evolution, including performance and reliability.
• AI-Assisted Engineering: Promote the adoption of AI-assisted practices to enhance code quality, automated refactoring, automated operations, and technical documentation.
• FinOps & Efficiency: Drive cost-aware architecture through cloud computing best practices, scalability, and platform/service efficiency, not merely focusing on savings plans or reservations.
• Technical Governance: Implement governance and controls that ensure the correct management of services, security, and compliance of our platforms and technologies, contributing to a culture of excellence.

Qualifications

• Software Engineering & Architecture:
  • Academic Foundation: Background in Computer Science, Engineering, or related disciplines.
  • Expert Development: Extensive hands-on experience in software engineering, with solid proficiency in Java (Spring Boot) and TypeScript/Python.
  • Distributed Systems: Mastery of Domain-Driven Design (DDD) and microservices architecture, designing for high performance and high availability.
  • Build: Deep knowledge of Bazel build systems.
• Cloud & Infrastructure (AWS Expertise):
  • Expert-Level AWS: Deep, practical experience with core services: EKS, Lambda, API Gateway, DynamoDB, S3, IAM, Networking, and Security.
  • Infrastructure as Code: Advanced experience with Terraform (modules/policy enforcement) and Pulumi (multi-language stacks).
  • Kubernetes Internals: Deep knowledge of EKS, including Karpenter for scaling, Istio for service mesh, and Argo/Flux for GitOps.
• Security, Reliability & Observability:
  • SRE & Resilience: Mastery of reliability patterns (circuit breakers, retries, back-pressure, stress tests, application architecture) and SLO-driven operations.
  • Security Hardening: Expert knowledge of AWS security controls, OPA/Rego policy design for admission controllers, and container security (image signing, ECR scanning).
  • Full-Stack Observability: Proficiency in OpenTelemetry design and integration with New Relic, Grafana, and Prometheus.
• Developer Experience (DevEx):
  • Self-Service Platforms: Proven experience building Internal Developer Portals and ephemeral environments.
  • Delivery Automation: Expertise in GitHub Actions, Flagger for progressive delivery, and feature-flag governance.
• Soft Skills:
  • Strategic Mindset: Ability to translate complex business goals into long-term technical direction.
  • Influential Leadership: Excellent communication skills to influence stakeholders and mentor technical leaders.
  • Autonomy & Accountability: High degree of ownership with a bias for action in fast-paced, large-scale environments.
  • Constructive Culture: Active contributor to feedback loops, ADR/RFC hygiene, and continuous learning.
• Industry-Specific Knowledge:
  • Real-world experience in critical workloads and regulated environments (ideally Fintech).
  • Ability to translate compliance controls (PCI-DSS, LGPD) into automated technical patterns.
