These are the six most recent of 51, as Antares published them. The wording is the employer's own; we do not rewrite a job title any more than we rewrite a filing.
Why the count alone says little
A large company always has hundreds of open roles. What carries information is which way that number moves, and which departments it moves in. We record both openings and closures, so a role disappearing from Antares's careers page is a recorded event rather than a silent absence.
Half of these roles were posted within the last 30 days, so this is a board that is actively moving rather than a backlog that has been sitting there.
Being straight about what this is
Not advice, and not a complete picture. This is one company's own careers page. It says nothing about revenue, headcount or plans, and we do not claim otherwise.
A short observation window. We started recording opens and closes on this set in August 2026, so "what changed" is weeks deep and grows daily. The posting dates above come from the employer and reach back further than our own record.
Refreshed once a night, read from eight applicant tracking systems. No salary fields and no candidate data: they are not in the source.
DataSignals Lab publishes data and research. Informational only, not investment advice, not an offer or solicitation. Every figure links back to the official filing so you can verify it yourself.
