Principal Backend / Data Architect

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.
