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 enable 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 over the rapidly evolving cyber-attack threats.

We’re seeking a Senior Software Engineer, Streaming Attribution to join our team. Our Internet Intelligence Platform is the growth product for Censys and it relies on us having a world-class Streaming Attribution engine for the most real-time solution in the industry. Our ability to correctly attribute internet entities (hostnames, IP addresses, etc.) to the correct organization is the foundation. It will require someone who has both deep internet knowledge and experience to build a highly scalable streaming attribution engine. In addition to deep internet domain knowledge, the candidate will have experience in data pipelines, stream/batch processing at scale, and building out APIs.

We expect all of our employees to consider customer happiness as our primary goal and a willingness to come to work every day with a great attitude, both eager to learn and educate, which helps to make us a better organization every day.

Why Censys Sticks Out:

• Humble Brilliance: We celebrate intelligence and foster a culture where tackling cybersecurity challenges is exciting and rewarding.
• A Mosaic of Minds: Our diverse team brings together various talents and backgrounds, fostering true innovation through diverse perspectives.
• Thinkers and Tinkerers: At Censys, we encourage questioning the status quo, experimenting, and pushing boundaries to drive breakthroughs.
• Coffee-Fueled Collaboration: Collaboration is at the heart of our success, fueled by a shared passion for disrupting the cybersecurity scene.
• Trailblazing Impact: Your innovations at Censys make waves in real-world cybersecurity, shaping the future and leaving a lasting legacy.
• Life Beyond the Firewall: We prioritize work-life balance and support your well-being inside and outside the office.
• Empowered Voices: Your voice matters at Censys; we champion an inclusive culture where diverse perspectives drive change.

What you’ll do:

• This role has 2 parts. First, you will research solutions to increase attribution coverage and reduce false positives. Second, you will help implement those solutions as code in the Streaming Attribution data pipeline.
• You will be using and exploring multiple technologies, often being the first to try a new platform or architectural design.
• Develop “pivot” microservices to find potential paths that can be attributed. For example, one might be certificate domains to IP addresses.
• Design automated solutions for building, testing, monitoring, and deploying applications in a Continuous Integration (CI) and continuous Delivery (CD) environment.
• Maintain a strong customer focus, prioritizing customer feature requests and helping define the Streaming Attribution roadmap.

What you’ll bring:

• A positive attitude biased towards action and iterative problem solving, learning as we grow every step of the way.
• A deep understanding of internet data and how internet asset attribution to a company might work. For example, WHOIS, Certificate Subject Alternative Names (SANs), and DNS record types should not be foreign to you.
• 3 years of experience building out scalable data pipelining solutions across billions of records.
• 5 years of experience with common data-oriented programming languages, such as Golang, Python, and Scala.
• 3 years of experience with continuous integration and continuous delivery tools and methodologies.
• Experience with REST/GRPC and service-oriented architectures.
• The ability to thoughtfully participate in technical discussions and drive towards data-driven decisions amidst ambiguity and competing priorities.
• Strong communication and documentation skills. Explaining complex technical concepts to other engineers, designers, salespeople, and content marketers is no problem for you.

Skills that set you apart:

• A cyber security engineering background with existing knowledge of helpful data sets and services that could be used for attribution.
• You have experience with multiple streaming and batch processing solutions such as Spark, Flink, GCP Dataproc, microservice-based designs with GCP PubSub, etc, and know their tradeoffs.
• You understand the value of building maintainable software. Some of your first tasks when building a new service are ensuring test coverage enforced by CI, adding linters, and adding code complexity checks. You enjoy a good abstraction, and promote established design patterns, but also know when to think outside the box.

Our target salary range for this role is between $160,000 - $190,000 USD bonus eligibility and equity.

We are located in Ann Arbor, Michigan, however we are open to hiring this position fully remote, with travel opportunities to meet customers and connect with colleagues.
