Pros
The management and the working atmosphere are very pleasant. I can reach anyone in the company and talk peer-to-peer. I feel no pressure; I work hard because I like the projects and feel my impact on the company's success. My colleagues are smart and pleasant people. The work is 100% remote and the time schedule is flexible. I can combine work and travel with no issues. There are not many calls or other scheduled events, and I can always move the events. The company has given unlimited days off to everybody recently. So, the work-life balance is great. The salary is very competitive. It's higher than 99% of software engineering positions in Russia. The salary is raised regularly (about once a year). There are no annual bonuses, but I get stock options; according to the latest investment round, the share that I'll receive in few years is already worth ≈$1M. The company is young but already profitable and the ARR grows. I don't doubt that the company will keep growing. I personally like that the company has not many employees yet, so it's pretty cozy. The company is software-developer-focused in terms of marketing positioning and internal processes. I have and use opportunities to grow professionally and to practice English. I'm happy to work here and I don't seek for a new job.
Cons
The following aspect is subjective. For me it's a plus, but somebody don't like it. The company is small and young, so there is almost no bureaucracy, low-level planning, terms, etc. The employees are artists rather than craftsmen. It means that you have a direction of work and you need to be autonomous enough to make researches and decisions and to build projects from scratch by yourself. Even better if you are initiative and propose new ideas. The company requires every employee to receive a MacBook from the company for free and work only on the MacBook. Very soon the company will control the MacBooks using Jamf (remote wipe, reset and maybe more). This is done for security, I understand this decision; just keep in mind if you are concerned about the privacy. There are no clear career promotion paths or education programs, so you can grow only through self-education. But the company itself is a good point in a CV for employees from regions like South America and Russia.
