Principal Software Engineer - TransactionsApply
About the job:
Twilio's customers send millions of communications every day. These communications become a firehose of micro-transactions, processed at a fraction of a penny at a time. As a pay-as-you-go service, it's critical to external and internal customers that we bill transactions in a timely and accurate manner. As a shared platform within Twilio, we have a responsibility to ensure that our systems can quickly and easily scale to support new products and use-cases.
We're seeking engineers with experience in real-time data processing, microtransactions, financial data, and a passion for API design & REST. We build our services in Scala and Python, and use Spark to process our large-volume data. Redis also plays a key role as a tool to coordinate processing in a distributed environment.
As a member of the Billing Platform team, you'll have an opportunity to take on some of the most challenging problems in distributed computing, HTTP, data persistence, and more. We're looking for someone who writes quality, maintainable code in Scala and Python with thorough test coverage in a continuous delivery environment. But more than just writing code, we need someone with the ability to break down requirements, estimate tasks and plan work accurately to ensure delivery to production.
As a Principal Engineer on the Billing Platform team, you'll lead development of services and tools to create scalable, reliable, resilient, accurate and secure capabilities of the micro-transaction system that processes customer usage data. You'll work directly with product management to define, architect, build and test new internal and external facing services. As an owner-operator of our services, you'll also develop evaluation, monitoring, and deployment plans to minimize operational risk and ensure that systems run smoothly from day one. As a Principal Engineer, you'll collaborate with other teams and mentor engineers on development best practices.
