Censys knows the internet and cloud better than anyone else. Attack Surface Management provides customers with an attacker-centric view of all externally facing internet and cloud to extend visibility, prioritize, and remediate the most critical risk exposures that will actually lead to a breach. Our daily IPv4 scans and the world's largest SSL/TLS Certificate database enables customers with the most accurate and continuously updated attack surfaces. Enterprise security teams leverage Censys to keep pace with the speed of the business and gain an advantage on the rapidly evolving cyber-attack threats.
Role Summary:
We're looking to hire a Distributed Systems Engineer to build highly-available and scalable, data-driven services that provide value directly to customers and across our organization. Censys operates distributed infrastructure for Internet-wide scanning, bulk DNS resolution, and X.509 certificate ingestion: your job will be to go below the surface of our data, and help us build the highest quality datasets and APIs.
At Censys, we believe in working iteratively, but we're always thinking about the big picture. We're building a platform that enables fast development of future products, and integration with new data collection methods. You'd be great for this position if you're someone who considers not just initial development, but ongoing maintenance and monitoring. You consider delivery and developer experience, and everything you do can be built upon in the future by others.
Role Responsibilities:

• Design and build services that power existing and future products at Censys by continuing to improve and expand our Internet Map.
• Build and extend large scale, real-time streaming services and applications which leverage our massive datasets to power internal product APIs and external applications.

• Interface with a polyglot codebase, including working with existing Scala and Go applications.

Required Qualifications:

• 3 years of software engineering experience writing distributed and streaming applications.
• Familiarity with functional programming and reactive programming techniques,
• Familiarity with object-oriented programming techniques and languages such as Go, Rust, or Python.
• Experience with message queue technologies such as Kafka, Google Pub/Sub, AWS Kinesis and delivery semantics such as Exactly-once and At-least once.
• Proficiency with distributed databases, such as BigTable, Cloud Spanner, HBase, Cassandra, with an understanding of trade-offs on consistency, durability, and replication of using such technologies.
• Ability to build horizontally scalable systems, with a high degree of availability and fault-tolerance leveraging techniques such as distributed locking, load-shedding, etc.
• Design automated solutions for building, testing, monitoring, and deploying data streaming pipelines in a continuous integration environment
• Interested in solving problems, not completing tasks
• Ability to write understandable, testable code with an eye towards maintainability
• Have strong communication skills and can explain complex technical concepts to other engineers, designers, and product managers.

Preferred Qualifications:

• Familiarity and comfort working in a Linux based environment.
• Familiarity with a service-oriented architecture using gRPC or REST to coordinate and communicate between services and systems.
• Familiarity with data serialization technologies such as Protobuf, MessagePack, etc.
• Experience building, deploying, and maintaining containerized services in a Kubernetes based environment.
• Experience working with cloud-native technologies and environments, such as AWS, GCP, or Azure.
• Collaborate and communicate well with other engineers working on related systems.
• Enjoy technical architecture discussions and want to drive technical decisions within your team.
• Continually improve skills, technical approaches, and familiarity with new technologies to help contribute to the success of the team.
