Our software runs in several IaaS cloud services for production scalability. We use Python as our primary development language, and appreciate a good microservice-based REST architecture.

Responsibilities

Designing and building efficient, scalable, and resilient RESTful and batch-based services that run in an IaaS provider such as AWS or Azure.

Committing tested, documented, and reviewed code on a frequent basis, ideally daily. Code reviews and automated testing are core to our quality approach. Task decomposition and continuous iterative delivery are a way of life at Pensa.

Collaborating with Product Management, UX, and other engineers to clarify requirements and design, and accurately estimating scope. A clear understanding of our customers’ needs, and how to make large amounts of data easy to consume is instrumental in this process.

Deep architectural understanding of good SaaS deployment patterns, and the technical options available from the various IaaS providers such as AWS or Azure.

Actively supporting our continuous journey of applying good architecture and design patterns so that we can do our best work every day. Strong opinions are encouraged.
