How to actually get hired at RadixArk
Why applying the normal way doesn't work
RadixArk runs an applicant tracking system (Ashby), but hiring managers still work referrals first. A cold application to RadixArk isn't dead, it's just fourth in line behind internal referrals, sourced candidates and recruiter pipelines.
Who to contact at RadixArk
No verified contact route for RadixArk yet. Expect the hiring manager for the team that's hiring to make the call, but treat this as a model, not confirmed data.
What RadixArk screens for
relevant experience and ability to operate autonomously
A tailored CV beats a generic one. Use RadixArk's job description language to clear filters.
Mistakes that kill RadixArk applications
Don't send the same CV you sent everywhere else. Whoever reads applications at RadixArk can tell, and it's the fastest rejection there is.
Don't open with what you want. Open with what RadixArk is dealing with right now — is growing, and what you'd do about it.
The wait-and-hope strategy fails. Follow up on day five — response rates roughly double.
