From disconnected data to confident, explainable decisions

data² delivers trustworthy, explainable AI (eXAI) that automates critical workflows and turns complexity into clarity. Our patented, hallucination-resistant eXAI reView platform harmonizes data across your ecosystem delivering real-time actionable insights.

Job Description

reView is a microservices backend over a graph data layer. Correctness in our system depends not just on API behavior, but on whether data is correctly structured, linked, and queryable across services. In a regulated-industry product, the difference between a result that runs and a result that is right is the entire value of the platform.

Concrete examples of what that means in practice:
- Did the right nodes and relationships get created across multiple services?
- Does a multi-step query return the correct result, not just a plausible one?
- Are data integrity guarantees holding under realistic load and failure conditions?

If testing API contracts and data integrity across a graph sounds interesting, this role is designed for that.

Scope




- Backend and data-focused testing (not UI-heavy)
- Integration and workflow correctness over broad end-to-end coverage
- Deeper performance and full-system validation evolve over time
- Embedded with the platform team, pairing closely with backend engineers
- Local and test environments are containerized (Docker-based), with shared staging for integration validation

Leveling

At the mid level, you will execute and extend an evolving test strategy. At the senior level, you will shape that strategy and influence how the platform is built for testability.

Requirements

API & Service Quality (Primary)
- Design and maintain automated tests for FastAPI services
- Validate request/response schemas, error handling, and auth flows
- Write tests across layers: unit tests (targeted handler-level validation), integration tests (service-level using test environments), and API-level smoketests against runnin
