• The company advertised an “Artificial Intelligence Researcher” role marked “Entry level”, with fit signals like Python proficiency rather than a long years-of-experience gate.
• 3AI’s current careers page lists a single opening, “Machine Learning Engineer”, described as mid-to-senior level.
• The company’s public footprint shows a very small team and a small number of open roles at a time, which makes early-career access feel intermittent rather than recurring.

‍

• The company outlines a sequence for at least one role that starts with a quick meeting with the CEO, followed by a “novel task” as an assessment.
• 3AI routes candidates to email or a general contact flow for “Joining the team”, which is workable for a small company but gives less process clarity than a standard ATS flow.
• The company’s Machine Learning Engineer posting is clear about responsibilities, tech stack (Python and C#), and the core requirements (numeric Python, cloud, testing and CI/CD).

‍

• The company advertises unusually direct senior exposure in at least one role, stating the CEO is the key contact through recruitment and offering reading sabbaticals intended to accelerate ramp-up.
• 3AI’s Machine Learning Engineer role includes “mentoring of junior team members”, which suggests juniors are expected to exist in the team structure at times.
• The company’s employee review feedback highlights easy access to colleagues and openness to ideas, paired with “lots of responsibility”, which usually means learning-by-ownership with limited guardrails.

‍

• The company does not publish salary ranges on the careers page roles reviewed, and at least one role asks candidates to reach out directly rather than applying into a pay-transparent process.
• 3AI has very positive compensation-and-benefits sentiment in the small number of public reviews available, but the sample size is too small to treat as reliable for most early-career candidates.
• The company mentions “competitive equity opportunities” in hiring copy, but 3AI does not publish equity mechanics or standard benefits in a way that helps juniors compare offers.

‍

• The company has only a small number of public employee reviews, but those reviews rate work-life balance, culture, and career opportunities at the top end and mention direct access to colleagues.
• 3AI’s LinkedIn footprint shows a very small employee base, so promotion velocity and 12–24 month retention patterns are hard to validate publicly.
• The company does not publish early-career outcome data such as internship conversion, time-to-promotion ranges, or retention reporting for junior cohorts, which caps this pillar.
