Pros & Cons
Helsing
- Highest talent density of any tech company — world-class AI and engineering leadership
- Extremely important mission with rewarding impact and competitive salary
- Ridiculous expectations of work hours — high salaries do not mean constant overtime
- Some management not experienced enough to lead; lacking in performance feedback
MongoDB
- World-class enablement — best training programs many employees have encountered
- Competitive pay with strong equity, especially for senior roles
- No 401k match and culture has gotten more political at scale
- Work-life balance is team-dependent — some teams have long hours expectations
Bottom Line
Helsing
Strong engineering culture with a clear mission — but that mission (AI for defense) is not for everyone. Research the ethics carefully before applying; those aligned will find unusually meaningful work.
