Senior Software Engineer, Web Application

Remote (US/Canada)

Company Background

Censys’ mission is to be the one place to understand everything on the internet. Frustrated by the lack of trustworthy Internet intelligence, we set out to create the industry’s most comprehensive, accurate, and up-to-date map of the Internet. 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.

Role Summary:

Censys is seeking a high-caliber Senior Backend Software Engineer to help build and evolve our next-generation Censys Platform. In this role, you’ll develop scalable microservices and design robust APIs that power our SaaS product. You’ll work closely with product and engineering teams to translate complex requirements into well-architected, maintainable software that powers critical security insights. Your contributions will help users explore and understand the global Internet, enabling them to uncover threats and better protect their organizations.

What You’ll Do:

• Design, build, and enhance backend services that power core functionality across the Censys Platform
• Partner with Product, Design, and Frontend Engineers to deliver features that solve real customer problems
• Integrate with internal and external APIs to support rich, data-driven experiences
• Own the full development lifecycle by automating build, test, deployment, and monitoring workflows
• Contribute to an iterative development process that emphasizes continuous improvement and rapid feedback

What You’ll Bring:

• 5+ years of professional experience building distributed web applications and APIs
• Strong expertise building backend microservices in Golang
• Experience with REST/gRPC and service-oriented architectures.
• Familiarity with Docker and interest in improving our CI/CD deployment process
• Desire to improve test coverage and increase code maintainability
• 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:

• Familiarity with a service-oriented architecture using gRPC or REST to coordinate and communicate between services and systems
• 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.

Censys is an equal opportunity employer. We welcome and encourage diversity in the workplace.
