/ The honest version
What this is, and what it is not.
Read this before you apply. If the right-hand column is a deal-breaker, it is better to know now than at the offer stage.
The upside
What is good about it
- Real systems, in production, with users who notice when they break
- A hundred people, so your work is visible and so are you
- CMMI Level 5 means the process exists, is written down, and is not invented per project
- Clients in 15 countries, which means exposure to how different markets build
The trade-offs
What it is not
- Not remote first. This is an office role in Kolkata.
- Not a startup. There is process, and some of it will feel like process.
- Not a research lab. The AI work is applied, on live operations, not experimental.
