Job summary

Titan OS is looking for a Data Platform Engineer to design, run and scale the cloud infrastructure that powers our data platform. You will build on AWS and Snowflake, manage Terraform/Terragrunt, and own CI/CD tooling used by data teams.

You will work with the Infra team and senior engineers to ensure reliability, security, cost efficiency, and a high-velocity data platform that supports our data engineers and product teams.

Qualifications

• 3+ years of experience in platform, infrastructure, DevOps, or cloud engineering, ideally supporting data workloads.
• Strong hands-on experience with AWS, especially IAM, S3, VPC/networking, KMS and Secrets Manager, plus at least some of Glue, EMR, Kinesis, MWAA, or Lake Formation.
• Solid experience with Terraform (Terragrunt a plus) and managing infrastructure across multiple environments and accounts.
• Experience building CI/CD pipelines (GitHub Actions or similar).
• Good Python skills for automation, tooling and internal libraries; comfortable with Bash.
• Experience with containers (Docker) and some exposure to Kubernetes.
• Experience running or supporting Apache Airflow (MWAA a plus) or similar orchestrators.
• Familiarity with data platform components (Snowflake or another cloud warehouse, Spark, Iceberg/Parquet).
• An operational mindset: monitoring, alerting, troubleshooting and on-call.
• Strong communicator and fluent in English.

Responsibilities

• Design, provision and operate the data platform's AWS infrastructure as code (Terraform/Terragrunt): S3, Glue, EMR, Kinesis, MWAA, Lake Formation, IAM, KMS and networking.
• Own the platform's CI/CD and developer tooling: GitHub Actions workflows, OIDC-based deployments, package publishing (CodeArtifact), local development environments, and our internal Python SDK/CLI that every data product is built on.
• Operate and scale our orchestration (Airflow on MWAA) and ingestion services: upgrades, environment management, capacity, reliability.
• Own privacy-critical workflows, including GDPR deletion pipelines, consent data and PII handling, with full auditability and fine-grained access control through AWS Lake Formation.
• Manage Snowflake as infrastructure: roles and access control, warehouses, integrations with S3/Iceberg, service accounts and secrets.
• Build observability for the platform: monitoring, alerting, logging, lineage and metadata tooling (OpenLineage, OpenMetadata), plus taking part in incident response.
• Track and optimise cloud costs across AWS and Snowflake (storage, compute, warehouses, job sizing).
• Apply security best practices: least-privilege IAM, encryption, secrets management and audit trails, in line with our ISMS.
• Work with Infrastructure, Backend and the data engineers to improve platform standard and remove friction from their workflows.
