Descripción de la vacante

dLocal, a global payments platform, is seeking a Cloud Architect focused on NoSQL and AWS to expand our data layer. You’ll own critical database services, drive performance, automation, and cost efficiency across our cloud data stack, including DynamoDB and MongoDB ecosystems.

You will design and optimize distributed databases, implement guardrails, and collaborate with distributed teams to ensure scalable, reliable solutions with robust observability and security.

Formación

• Hands-on, senior-level expertise operating DynamoDB in production, including data modeling, capacity strategy (provisioned/on-demand), GSIs/LSIs, TTL, Streams, backup/restore, and multi-region patterns.
• Experience with AWS MSK or Kafka for event-driven and streaming use cases.
• Experience with DocumentDB and/or MongoDB administration (cluster sizing, replication/sharding, indexing, backups, upgrades, performance tuning).
• Solid command of AWS cloud fundamentals for data platforms (IAM, KMS encryption, networking basics, S3 patterns, monitoring/alerting with CloudWatch; DMS and Lambda are a plus).
• Automation proficiency using Python or JavaScript/TypeScript, GO the AWS CLI, and SDKs to build repeatable operations and safety checks.
• Working knowledge of relational databases as a plus (MySQL/Aurora, PostgreSQL) to partner with peers.
• Clear communication in English and a collaborative, service-oriented mindset working with distributed teams.

Responsabilidades

• Own, operate, and optimize DynamoDB workloads in production, including data modeling, capacity strategy, GSIs/LSIs, and multi-region patterns.
• Design, deploy, and maintain relational and non-relational databases, including sharding, indexing strategies, backups, and performance tuning.
• Leverage AWS data stack services (S3, KMS, IAM, CloudWatch, DMS, Lambda) to build reliable, observable, and secure data solutions.
• Implement automation‑as‑code for schema and capacity changes, operational tasks, and guardrails to reduce toil and error.
• Establish and improve observability for databases (metrics, logs, traces, dashboards, SLOs/alerts) and lead RCAs.
• Collaborate with engineers to design data access patterns and guide migrations with minimal downtime.
• Participate in reliability engineering (backups, DR, chaos testing, incident reviews) across NoSQL platforms.
• Join on‑call rotations and assist during off-hours as needed.
