Design and manage multi-tenant PostgreSQL database architecture for a SaaS product ensuring performance, reliability, security, and developer experience on AWS with automated testing and observability.
7+ years PostgreSQL production experience, expertise in multi-tenant design, AWS PostgreSQL tuning, strong security and compliance knowledge, .NET integration experience, automated testing, and excellent communication skills.
Job Description: • Own the database architecture for a multi-tenant SaaS: select and implement tenancy model(s), design schemas, and define migration/versioning strategies for safe, zero-downtime releases. • Raise the performance ceiling: index strategies, partitioning, connection pooling, query tuning, caching patterns, and workload isolation for noisy-neighbor control. • Build for reliability: set RTO/RPO targets; design backup, PITR, DR, and blue/green or expand-migrate-contract rollout patterns. • Embed security & compliance: encryption in transit/at rest, least-privilege access, secrets management, audit logging, PHI handling, and HIPAA-aligned controls and documentation. • Productionize on AWS: stand up and tune Aurora/RDS for PostgreSQL; integrate VPC, subnets, SGs, KMS, CloudWatch/CloudTrail; advise on ECS/EKS/Fargate service patterns that affect DB workload. • Level-up developer experience: define database interfaces for .NET services, enforce SQL and migration conventions, and enable efficient local/dev/test workflows (containers, seed data). • Test like you mean it: establish automated database testing —pgTAP or equivalent for unit tests, migration tests in CI, and load/perf testing harnesses tied to release criteria. • Observability & SLOs: build dashboards and alerts for latency, throughput, autovacuum, bloat, locks, and error budgets; drive incident reviews and continuous tuning. • Partner & influence: work shoulder-to-shoulder with our architect, app engineers, QA, and security to ship features that are correct, fast, and safe—while advocating best practices. • AI First Mentality: Use modern AI tools to draft queries/migrations/tests, explain query plans, generate fixtures, and accelerate root-cause analysis responsibly and securely. Requirements: • 7+ years owning PostgreSQL in production at scale for a SaaS product. • Demonstrated expertise in multi-tenant design (RLS, schema or DB-per-tenant), with opinions on trade-offs. • Proven track record of query and schema optimization, indexing, partitioning, and connection management. • Hands-on experience running PostgreSQL on AWS (Aurora or RDS) and tuning for throughput & cost. • Strong security mindset: access control, secrets, encryption, auditing; experience operating under compliance frameworks (HIPAA preferred, but experience within any regulated industry). • Experience enabling .NET services to use Postgres effectively (EF Core, Dapper, migrations). • Habit of building automated testing for databases and performance/load gating in CI/CD. • Excellent communicator who can write clear design docs, propose standards, and influence cross-functional teams. • Ability to speak up and express opinions or concerns in a positive and constructive manner. • AI First Mentality on developing schema design, migration strategies and automated testing for performance. Benefits: • Health insurance • Flexible work arrangements • Professional development opportunities
