Your Role:
Tenable is seeking a Senior Software Engineer to join our VM Platform team. Our team sits at the center of our Tenable One architecture; we ingest massive volumes of assets and find data from collection teams, process it to calculate the "state of the world" for our customers, and feed it to downstream search and reporting products.
We are not just building web apps; we are solving a complex Big Data problem. You will build and maintain the high-throughput, event-driven pipelines responsible for processing the history of assets and vulnerabilities. You will move beyond simple CRUD operations to design systems that handle massive scale, ensuring that when we say an asset is vulnerable (or patched), that data is accurate and available in real-time.
To be considered for this role, you must meet one of the following criteria:
- Hybrid: Ability to commute to our Columbia, MD/Northern VA office.
- Hybrid: Ability to commute to our Boston, MA office.
- Remote: Currently reside in the San Francisco Bay Area, CA
Your Opportunity:
- Build the Future of Exposure Management: We are currently developing the backend that powers Tenable’s flagship Exposure Management (EM) platform. You will be building the future that powers our EM platform.
- Solve Complex Data Problems: Work on "team-named data processing" challenges. You will design logic that collapses millions of incoming findings into a single, accurate state record.
- Architect for Scale: Transition our systems to a new architecture designed to be faster, cheaper, and more reliable. Your work will unblock integrations across the entire company.
- Own Your Stack (DevOps): We support our services in the wild. You won't just write code; you will use Terraform and Datadog to deploy, monitor, and ensure the health of your services in production.
What You’ll Need:
- 4+ years of Backend Engineering experience with a focus on high-volume data processing or distributed systems.
- Strong JVM Proficiency: Deep experience with Java, Kotlin,is required. You should understand memory management and performance within the JVM ecosystem.
- Stream Processing Architecture: Proven experience with Kafka (ideally), AWS Kinesis, et al. You understand topics, partitions, and how to process teams of data asynchronously
- To be considered for this role, you must meet one of the following criteria: Hybrid with the ability to commute to our Columbia, MD/Northern VA office, Hybrid with the ability to commute to our Boston, MA office, or Remote: Currently reside in the San Francisco Bay Area, CA
- Distributed Systems Knowledge: You understand the challenges of microservices, eventual consistency, and data resiliency.
- Stateful Processing Logic: Experience calculating "state" from a history of events. You understand how to take a stream of raw data and "collapse" it into a current status.
- DevOps Mindset: Hands-on experience with Terraform for infrastructure-as-code and observability tools like Datadog to monitor metrics and graphs.
- Database Experience: Proficiency with SQL and NoSQL data stores (PostgreSQL, DynamoDB, or similar) to store and retrieve state data.
And Ideally:
- Experience with Event Sourcing or CQRS patterns.
- While security background is a plus, we value Big Data/Data Pipeline experience first. If you can process data at scale, we can teach you the security domain.

The Platform Services team builds and maintains the systems that software developers across NCBI use to ensure that they are consistently pushing and deploying high quality code that complies with Federal Standards for application security and mature code practices. We're involved in the entire development lifecycle including:
- Tools for creating and setting up new projects consistently across the org.
- CI pipelines and build tools for consistent expectations across languages and application frameworks
- Testing frameworks and metrics to assure only quality and secure code can be sent to production.
- Deployment and publishing pipelines to bring applications to their users in on-premises and cloud environments, and to provide public access to Open Source projects.

- Documentation knowledge bases for each component project and the DevEx platform as a whole, in READMEs and on Confluence.
- Leading smaller projects within the DevEx teams to add new capabilities to the platform.
What we look for
While we have roles at all levels of experience, we are looking for proactive developers with some experience building software or maintaining DevOps infrastructure and a strong interest in learning more.
Required Skills
- Strong coding fluency in at least one programming language. NCBI uses Python, C++, JavaScript/Typescript, some Kotlin & Scala, and small amounts of Golang and Rust.

- Familiarity with GitLab CI/CD pipelines
Bonus skills and experience
- Experience building high availability applications
- Experience configuring multi-tenent Kubernetes clusters
