Clearance Requirements

Several Reenblox positions require security clearance. Clearance applications are initiated by the company following a conditional offer and are conducted by a third-party assessment body.

Candidates are advised that clearance processing can take between 4 and 16 weeks depending on the level required for the role.

Roles designated RD-tier require the highest clearance level. These processes are handled exclusively by the Depth Mapping Authority.

A Note On Field Roles

Field positions at Reenblox are not typical survey postings. Our sites are often remote, access is restricted, and some locations present environmental conditions that require specific preparation.

We do not misrepresent this. Candidates who are uncomfortable with extended isolation, irregular instrumentation behavior, or working in environments that are not fully characterised should consider whether field placement is the right fit.

We find that the people who thrive at Reenblox are those who are comfortable not having all the answers immediately.
