Your Career

As a Senior Software Engineer on this team, you will contribute to the entire development lifecycle of our systems. Your responsibilities will range from designing and building scalable backend services and APIs to developing robust frameworks and internal tools. You will work on creating efficient, reliable systems that support our platform's core functionalities and enable other engineering teams to build and innovate effectively.

Your Impact

  • Design, build, and maintain the core services and data pipelines for our Attack Surface Management platform.

  • Take part in architecture strategy sessions—work with your colleagues to design solutions that accommodate the requirements of the various modules across Cortex.

  • Collaborate with your team to solve problems, reduce technical debt, and evolve development practices.

  • Drive technical best practices and evangelize new technologies within the engineering organization.

  • Collaborate with other engineers and ensure that your team delivers high-quality output.

  • Take ownership of projects, drive them to completion, and support them in production.

Your Experience

  • 5+ years of professional experience in software engineering, with a proven track record of designing, developing, deploying, and supporting complex, scalable software systems.

  • Proficiency in one or more programming languages such as Python, Java, or Golang.

  • Extensive experience with API design and development, including RESTful APIs and microservices architecture.

  • Demonstrated experience in building and maintaining data pipelines and ETL processes.

  • Working knowledge of data processing frameworks and tools (e.g., Apache Spark, Apache Beam, or similar).

  • Significant experience with software development best practices, including CI/CD, automated testing, and agile methodologies.

  • Significant experience working with at least one major cloud platform (e.g., GCP, AWS, or Azure), and their data services.

  • Proven experience driving design and implementation of technical solutions in the face of ambiguity—we will ask you about this.

  • Experience and interest in mentoring other engineers in order to contribute to the technical growth of the team.

In this role, you will be an integral part of the group that enables customers to engage with their data through our web application. You will work across teams to architect solutions to some of our most challenging technical problems, then lead projects to implement them, including designing and building data models, APIs, and user interfaces for user-facing features. You will draw upon your experience to rapidly investigate and prototype new functionality, then switch to implementation mode to deliver products. You will guide and mentor your team in enterprise software development, architecture and technical design, and the evaluation thereof. You will represent your team in technical roadmap planning and cross-team design review sessions, working regularly with senior engineers from other teams, UX designers, and product managers.
