About the Role

We’re looking for a Senior hands-on full-stack engineer with strong TypeScript skills and deep AWS experience, who’s excited to modernize how we build, deploy, and run cloud services. You’ll work across product and infrastructure, shaping scalable, secure, and reliable systems using Infrastructure as Code. Team-leading experience is a strong plus, and familiarity with Pulumi (or similar IaC tools like Terraform/CDK) is highly valued. Great opportunity to take a leading role.

Lead the team in delivering high-quality features end-to-end, setting strong engineering standards, and ensuring reliable, well-structured environments across development, staging, and production.
Ensure infrastructure follows best practices for security, monitoring, cost efficiency, and disaster recovery.
Perform root cause analysis and debugging for complex production issues across AWS infrastructure and application layers.
Drive improvements in Backend / Frontend / DBA / DevOps practices, documentation, and team workflows.

Strong grasp of IAM and security best practices: role and policy design, secrets management, least privilege enforcement, and cloud identity governance.
Familiarity with observability tools (e.g., CloudWatch, Datadog, Prometheus, Grafana) for monitoring, logging, and incident response.
Comfortable working in a fast-paced, collaborative team environment, with a high level of ownership, accountability, and adaptability.

Nice to Have
