You will be responsible for designing, evolving, and ensuring the reliability of the database infrastructure that supports millions of operations daily. We expect you to act as a technical reference for the team, collaborate on architectural decisions, and promote a culture of excellence, automation, and security.
This is an opportunity for someone who masters database environments, cloud technologies, software knowledge, security, and thinks like a platform owner. This is a remote opportunity, under a CLT contract, with a 40-hour work week.
Join us in helping companies manage their businesses simply and intelligently through technology!
Responsibilities and Attributions
Responsibilities:
- Design and evolve distributed, resilient, and scalable database architectures on AWS, focusing on high availability and disaster recovery (DR).
- Administer and perform deep tuning of MySQL/MariaDB engines and TiDB clusters, ensuring performance in high-concurrency scenarios.
- Lead architectural reviews (Design Reviews) with Product and Engineering teams, ensuring data design supports business growth.
- Develop robust automations using Python, Go, or Bash for infrastructure provisioning, maintenance, and self-healing (IaC).
- Implement and maintain an advanced Observability strategy, going beyond basic monitoring to include distributed tracing and structured logs for rapid anomaly detection.
- Mentor analysts and engineers, raising the team's technical bar in modern database and cloud practices.
- Ensure data security "by design," implementing hardening, encryption (in transit and at rest), access management (IAM with least privilege principle), and compliance with network policies.
- Lead critical incident response (War Rooms), conducting Post-Mortems focused on preventing recurrence.
Requirements and Qualifications
Technical Requirements:
Database Core & Distributed Systems:
- MySQL/MariaDB Mastery: Deep knowledge of internal architecture (InnoDB), replication (GTID, Galera, Async/Semi-sync), partitioning, manual sharding, and complex performance troubleshooting. Practical experience in administering, operating, and tuning clusters.
- Data Migration: Experience with Change Data Capture (CDC) tools or migrating monoliths to distributed architectures.
- Observability: Ability to diagnose problems beyond CPU/RAM, interpreting wait events, slow logs, and distributed tracing.
Cloud & Infrastructure (AWS):
- Advanced AWS: Hands-on experience with EC2 (instance families, EBS IOPS, Nitro), VPC (Peering, Transit Gateway, PrivateLink), S3, and advanced IAM in both managed and unmanaged environments.
- Security (SecOps): Solid knowledge of database hardening, encryption (KMS, TLS/SSL), secrets management (Secrets Manager/Vault), and compliance (Security Hub).
Engineering & Automation:
- Infrastructure Automation: Fluency in Bash and at least one robust scripting language (Python or Go) for creating automations, internal CLI tools, and maintenance scripts.
- FinOps & Costs: Proven experience in cloud cost management (Rightsizing, use of Spot/Graviton instances, and tagging strategy for cost allocation).
Differentiators
- Experience with TiDB (or similar NewSQL): Practical experience in administering, operating, and tuning TiDB clusters (PD, TiKV, TiDB), understanding distributed storage concepts and consensus algorithms (Raft).
- Infrastructure as Code (IaC): Experience with Terraform or similar for database provisioning.
- Kubernetes: Ability to operate databases within Kubernetes (using TiDB Operator or similar) is a significant plus.
- Development Background: Ability to read and debug application code (PHP, Node.js, or Go) to help developers refactor inefficient queries directly at the source.
- SRE Mindset: Experience with defining SLIs/SLOs/SLA, Error Budgets, and using modern monitoring tools (Prometheus, Grafana).
- Good practices with FinOps, managing cloud budget, implementing tagging strategies, and continuous cost optimization (Rightsizing, Savings Plans, serverless architecture when applicable).
