Senior Data / Platform Engineer

**About THIA** THIA is transforming how small and medium enterprises build internal applications and automate business processes. Our AI\-powered platform enables business experts to create custom applications using natural language, eliminating the need for expensive development teams. We're well\-funded, generating revenue, and solving real problems for companies that need more than off\-the\-shelf software. **The Role** This is a high\-impact, hands\-on role where data engineering and cloud infrastructure are equally part of the job. You'll own delivery across multiple products and environments — designing schemas, building pipelines, writing Terraform, and spinning up new environments from templates. You'll work closely with a small, senior team and have real influence on technical direction. We move fast, keep our codebase clean, and take tech debt seriously. **What You'll Do** **Platform \& Data Engineering** * Own end\-to\-end infrastructure delivery across all products and environments — from Terraform modules to production deployments * Write and maintain Terraform for our full cloud environment: networking, compute, databases, storage, and secrets management * Deploy and operate containerized services; spin up new environments from templates * Design, build, and optimize PostgreSQL databases and data models for our in\-house built data platform architecture * Build and maintain ETL/ELT pipelines and file\-processing functions * Manage multi\-environment deployments via GitLab CI/CD * Maintain authentication infrastructure (Keycloak/OIDC) across products and client environments * Manage secrets, service accounts, and IAM across multiple cloud projects * Implement security controls aligned with SOC2; remediate findings and keep access policies current * Handle production issues and incident response **Collaboration** * Work autonomously while staying tightly coordinated with a small, async\-first team * Collaborate with AI and App engineering teams on service integrations and API design * Contribute to architectural decisions and internal documentation **What We're Looking For** **Must\-Haves** * Strong PostgreSQL expertise: schema design, query optimization, performance tuning * Hands\-on Terraform experience managing real cloud infrastructure * Docker and managed container platform experience * Experience building and maintaining CI/CD pipelines * Cloud infrastructure experience — GCP preferred, any major cloud considered * Self\-directed, ownership mentality **Strongly Preferred** * Past ownership and maintenance of a production system used by real customers * Background in a startup environment **Nice to Have** * Terminal/CLI\-first approach — preference for scripted, repeatable solutions over manual UI workflows **A Note on AI** We actively encourage using AI tools to move faster. Real\-world experience is still required to direct AI effectively, catch what it misses, and spot security issues before they reach produ
