## Description

We are looking for a senior software engineer to help us build the next-generation network data plane to enable our Confluent Cloud platform to achieve 10x the current scale. This role blends strong independent software development with hands-on operational ownership.

Cloud networking is a strategic investment area with significant potential to impact the company's growth. The Traffic team is responsible for the network platform of Confluent Cloud with a focus on performance, security, reliability, and cost optimizations for all network traffic that ingresses and egresses a customer's Kafka and DSP deployments as well as all internal service to service traffic on Confluent Cloud.

You will design and build highly scalable, cost efficient, networking data plane solutions, while ensuring these systems are reliable, observable, and resilient in production. You'll independently drive complex projects from design through production, working closely with engineers across the Traffic team, and help grow more junior engineers along the way.

Key Responsibilities:

 * Design, develop, and operationalize high-performance, scalable, reliable, and resilient systems for the Confluent Cloud network data plane platform.
 * Independently drive the execution of software projects, delivering complex work in production with a focus on quality.
 * Leverage cloud providers and open-source software to deliver impactful business solutions.
 * Troubleshoot and improve operations for a complex technical stack that spans across AWS, Azure, and GCP, including microservices, containers, and virtualization.
 * Mentor junior engineers on the team, helping them grow their technical skills and engineering judgment.
