We are looking for a Principal Backend & Data Architect to own the architecture of a complex data-intensive product from the ground up.
This is a hands-on technical leadership role for someone who has designed production-grade platforms where data modelling, versioning, traceability, permissions and long-term architectural decisions are critical.
What you will own
Core backend and data architecture
Domain and data modelling
Versioned and temporal data structures
Data provenance, lineage and historical recomputation
Multi-tenant architecture and data isolation
Permission models including RBAC / ABAC
Auditability and traceability
Computation and semantic layers
Technical standards and architecture documentation
Technical leadership and review of backend implementation
What we are looking for
8+ years of backend/software engineering experience
Proven experience architecting complex, data-heavy production systems
Excellent system design and data modelling skills
Strong PostgreSQL / SQL expertise
Experience with distributed systems, queues, background processing and APIs
Experience with temporal, versioned or event-driven architectures
Strong understanding of multi-tenancy, authorization and data security
Ability to make architecture decisions and remain hands-on during implementation
Experience leading senior engineers technically
Strong advantage
Experience with regulated or sensitive data, healthcare, fintech, insurance, IoT, analytics or decision-support platforms.
This is not a pure management or solution-architecture role. We are looking for someone who can design the foundation, challenge assumptions and stay close to implementation.
