Job description

Overview

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 or Canada.

Role

We’re seeking a Full Stack Engineer with a backend focus to join our Threat Hunting and Advanced Solutions team. This team is responsible for building high-impact product features and workflows on top of the Censys platform. You’ll design and deliver APIs that power core experiences in the platform, while also contributing to frontend features. You’ll collaborate closely with product, design, and engineering peers to deliver secure, resilient, and user-friendly workflows. Your work will directly shape how customers discover, investigate, and respond to threats on the Internet.

What You’ll Do

• Develop and maintain backend APIs in Go, including integrations with distributed data and AI-powered services.
• Design production-grade systems end-to-end, with a focus on scalability, fault tolerance, and spec-driven development.
• Model and query relational data (e.g., Postgres, MySQL), applying a deep understanding of SQL and database semantics (consistency models, isolation levels, indexing, and query optimization).
• Apply distributed systems concepts (idempotency, retries, consensus) to ensure reliable workflows.
• Help push real software to production by contributing to CI/CD pipelines, testing automation, deployment strategies, and implementing observability and monitoring practices to validate system behavior in distributed environments.
• Work cross-functionally with product managers and designers to plan and deliver impactful features.

What You’ll Bring

• Professional experience with Golang for building production services.
• Proficiency with SQL and a strong understanding of database semantics.
• Hands-on experience designing and implementing performant gRPC services.
• Frontend Development
  • Collaborate with frontend engineers to support end-to-end delivery.
  • Ensure smooth integration between backend services and frontend applications.
• Experience reasoning about system design tradeoffs (scalability, performance, resilience, fault tolerance).
• Familiarity with distributed systems concepts and messaging patterns (idempotency, retries, consensus, pub/sub).
• Proficiency with containerization and orchestration technologies (Docker, Kubernetes) and deploying services in cloud environments (GCP, AWS).
• Quality and Reliability
  • Strong commitment to building resilient, high-quality systems backed by effective testing strategies.
  • Experience validating distributed system behavior beyond unit/integration tests.
  • Familiarity with observability and monitoring tools; comfort handling sensitive data securely.
• Ability to communicate technical information clearly to different audiences.
• Partner cross-functionally with product, design, and engineering peers to align on priorities and deliverables.

Bonus Points

• Experience integrating backend services with AI/LLM systems.
• Familiarity with frontend performance considerations in data-heavy applications.

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
