Long hours, for one. Perhaps lack of job security. Likely an immature set of processes, or no process at all. You'll probably be expected to wear many hats.

Long hours, for one. Perhaps lack of job security. Likely an immature set of processes, or no process at all. You'll probably be expected to wear many hats. That is, develop, QA, maintain build systems, deal with customers, etc. A lot of this depends on how new the startup is and how many employees. Now for the good points: - likely very little bureaucracy - usually very interesting projects - the ability to pivot (change product direction) very quickly, so you won't be bored - progressive environment You may be offered a couple choices for compensation. For example, 1% of the company in stock & $80k or 0.5% stock and $85k.
