Role Summary:

Censys is seeking a high-caliber Senior Full-Stack Engineer with a strong backend focus 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. While your primary focus will be backend systems, you’ll also contribute to frontend development to deliver intuitive, crafted user experiences. 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:

• Partner with Product, Design, and Frontend Engineers to deliver features that solve real customer problems
• Design, build, and enhance backend services that power core functionality across the Censys Platform
• 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:

• 4+ years of professional experience building distributed web applications, APIs, and frontends
• Expertise building backend microservices in Golang
• Strong experience with common web programming languages such as TypeScript and JavaScript, and at least proficiency in one frontend web framework (e.g. React, Angular, Vue, or Next)
• Familiarity with Docker and interest in improving our CI/CD deployment process
• Desire to improve test coverage and increase code maintainability

This Role Might Be A Good Fit If You…

• You thrive in a fast-paced environment where change is constant, and you are able to navigate with ease and adaptability
• You take ownership of projects and don’t wait for direction—you proactively find ways to move forward
• You believe that to be your best, you need to work alongside the best, and you welcome constructive feedback as part of a growth mindset
• You hold yourself to high standards, striving for excellence in everything you do
• You proactively seek opportunities to go above and beyond, driving innovation, improving efficiency, and enhancing the team’s overall output
• Your soft skills are just as strong as your technical expertise—you excel at collaboration and communication, and people looking forward to working with you

This Role Might Not Be A Good Fit If You…

• Believe that engineering’s role ends once the code is delivered, rather than throughout the product life cycle
• Don’t value the code review process or resist constructive feedback
• Settle for the status quo and don’t seek improvement
• Prefer to wait for direction instead of taking the initiative
• Don’t enjoy supporting and mentoring your colleagues to foster team growth

Our target salary range for this role is between $135,000 USD and $180,000 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 and our innovation is fueled by the team’s global perspectives. For this role, we are open to remote employees across the continental US.
