Senior Software Engineer, Streaming Attribution

At Censys, our mission is to bring internet visibility and intelligence to the world’s security teams. Our platform not only identifies potential threats, but provides actionable insights and enables proactive defense strategies. Founded by researchers and practitioners, we are deeply committed to the quality, trustworthiness, and transparency of our data and results. As our own strongest critics, we continuously innovate to better understand the Internet and empower our customers with the visibility they need to succeed.

Role Summary:

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 processing and analyzing billions of internet telemetry data points. The candidate will have experience in data pipelines, stream/batch processing at scale, and building out APIs. Having a solid understanding of internet inter-workings is a big plus.

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 $170,000 - $205,000 USD + bonus eligibility and equity.

In addition to our great compensation package, our benefits are effective on day one and include but are not limited to 401k match, health, vision, dental, and more! Please see our careers page for more details.

Our roots are in Ann Arbor, Michigan with location hubs in Seattle, the Bay Area, and Tysons, VA. Our innovation is fueled by the team’s global perspectives and diverse backgrounds. For this role, we are looking for candidates based in one of our four hub locations: Seattle, WA, Los Altos, CA, Tysons, VA, or Ann Arbor, MI.

Don't meet every single requirement? Studies have shown that women and people of color are less likely to apply for jobs unless they feel they meet every qualification. At Censys we are dedicated to building a diverse, inclusive, and authentic workplace - so if you're excited about this role but your past experience doesn't align perfectly with every listed requirement in the job description, we encourage you to apply anyway. You may be exactly who we need to fill this role or others!
