Today, Censys delivers real-time Internet intelligence and actionable threat insights to global governments, over 50% of the Fortune 500, and leading threat intelligence providers worldwide.
Location: This position is remote within the United States or Canada.
Role Summary:
Censys is seeking a Senior Backend Engineer to join our Exposure Management team. Our Exposure Management solution is a growth product for Censys and depends on a world-class backend architecture to deliver real-time, high-fidelity visibility to our customers. We’re looking for an engineer who can design, build, and extend large-scale, real-time backend services that leverage Censys’ massive datasets to power internal product APIs and external customer-facing applications.
This role requires someone who is comfortable owning backend services end-to-end, integrating data from multiple internal systems, and operating in production environments where reliability, observability, and correctness matter. As with all roles at Censys, we expect a strong customer focus, a collaborative mindset, and a desire to continuously learn and improve both our systems and our team.
What You’ll Do:
- Design, build, and own backend APIs and gRPC services that integrate data from multiple internal teams and systems in a clean, well-architected manner
- Build and evolve real-time and near–real-time backend services and data pipelines that power Exposure Management and Attack Surface Management products
- Leverage AI and LLMs to enhance automation, accelerate development workflows, and improve customer-facing intelligence
- Partner closely with Product and other Engineering teams to prioritize features, influence the Exposure Management roadmap, and deliver customer value on tight timelines
- Provide technical leadership through design reviews, mentorship, and setting a high bar for code quality, performance, and operational reliability
- Design and maintain automated CI/CD workflows, including testing, monitoring, alerting, and deployment, to ensure services are production-ready and observable
What You’ll Bring:
- A positive attitude biased towards action and iterative problem solving, learning as we grow every step of the way.
- 5+ years of experience in software engineering.
- 3+ years of experience with Golang.
- Experience designing and consuming REST and gRPC APIs in service-oriented or microservice architectures
- Strong distributed systems fundamentals, including experience building horizontally scalable, fault-tolerant systems
- 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.
What Sets You Apart:
- Strong interest in harnessing AI and LLM tools as a force multiplier - using it to code smarter, iterate faster boosting productivity and enhancing product capabilities
- You have experience with microservice-based designs with GCP PubSub, etc, and know their tradeoffs.
- Experience building, deploying, and maintaining containerized services in a Kubernetes based environment.
- 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.
- A deep understanding of how the Internet works. For example, WHOIS, Certificate Subject Alternative Names (SANs), and DNS record types should not be foreign to you.
