Postmark is a cloud email infrastructure product that allows businesses to send and receive transactional emails from their applications. We make it easy for our customers to add email communication to their applications using a full-featured REST API, as well as through the standard SMTP protocol.
What’s it like to work on Postmark
A Postmark backend engineer will primarily write C# code to improve and enhance the API and backend services. You will use/improve/scale out our infrastructure software which currently consists of MySQL, RabbitMQ, and Elasticsearch.
A Postmark engineer is responsible for their tasks, breaking them up into manageable bits with an emphasis on deployability and backward compatibility, communicating technical decisions to the engineering team, and communicating timelines and customer impact to the product manager.
A Postmark engineer is responsible for the health of our production system. You’ll be part of an on-call schedule and help mitigate abuse of the system by spammers.
You’ll scale-out infrastructure, optimize code and queries, and make changes to improve reliability.
Engineers on Postmark have a tremendous amount of autonomy on the technical direction of our product but are held to a high standard for the reliability, maintainability, and usability of code they write. With this autonomy, individual engineers are expected to evaluate the current landscape of our product, as well as consider future directions to develop the best solution for today, with the understanding that there will be inevitable time constraints associated with growing and maintaining a successful product like Postmark.
How interviews typically go:
- A few short written questions to gauge technical skill and written communication.
