mtmail is correct, they are used interchangeably now, for the most part. Still, there's a difference. To me a developer is someone who creates software. They may design it, or be implementing someone else's design. An software engineer is someone who uses a repeatable process to design software, possibly also implementing it, and who takes the necessary steps to enable communicating details of the software to stakeholders (users, management, customers, other teams, etc.). For me, what differentiates a software engineer from a developer is enabling communication and using process. A good software engineer will be continually improving their processes, and documenting them so other engineers can learn from their successes (and mistakes) - which is another area where communication comes in. The better the developer, the more they become a software engineer, in my opinion.
