Job Summary
Architect production-scale TypeScript monorepos using Nx or Turborepo, design Next.js and Node.js services, and implement deep PostgreSQL data modeling for financial or ledger-style systems with strict transactional integrity. Embed security and compliance directly into architecture by designing RBAC/MFA, immutable audit trails, and data residency strategies aligned with SOC 2 Type II and the EU Data Act. Demonstrate the ability to design data isolation architectures for systems combining sensitive persisted data with AI or third-party processing. This role requires proven experience in fintech or regulated domains, cloud-agnostic IaC fluency, and collaboration with security-focused teams from the Discovery phase. Start date is end of September 2026 for a 4-month project duration.
Required Qualifications
- Proven experience architecting TypeScript monorepos (Nx or Turborepo) at production scale
- Deep experience with Next.js and Node.js service design
- Strong PostgreSQL data modeling experience, ideally with financial or ledger-style data (transactional integrity, auditability, state machines)
- Hands-on experience designing security and compliance into an architecture — RBAC/MFA, immutable audit trails, data residency/segregation — rather than bolting on controls after the fact
- Working familiarity with SOC 2 Type II and/or the EU Data Act (or comparable regulatory frameworks), with the ability to translate compliance requirements into concrete architectural decisions
- Demonstrated ability to design data isolation/segregation architectures for systems that combine sensitive persisted data with AI or third-party processing
Desired Qualifications
- Prior architecture experience in fintech or another regulated domain (healthtech, insurtech, etc.)
- Cloud-agnostic Infrastructure-as-Code fluency (Terraform or similar) to keep a three-environment setup vendor-neutral
- Experience working alongside a security-focused PM or compliance function from the Discovery phase onward
