Reimagine the infrastructure of cancer care within a community that values integrity, inspires growth, and is uniquely positioned to create a more modern, connected oncology ecosystem.

We’re looking for a Security Engineer to join our Security Assessment team to help us accomplish our mission to improve and extend lives by learning from the experience of every person with cancer.

What You'll Do

In this role you will report into the Security Assessment Team and will be a central part of the larger Information Security organization that works to keep our patient data and applications secure.

You’ll work across various security specialties to automate and optimize current workflows, as well as create novel solutions to industry problems. In addition you will:

  • Lead vulnerability management efforts across all domains, including application security (SAST and SCA) and cloud infrastructure (Infrastructure and IAM).
  • Coordinate between a variety of teams and stakeholders to prioritize and remediate security findings, effectively managing conflicting priorities to make meaningful changes in our environment.
  • Perform expert triaging of security tools results and penetration test findings to identify and escalate critical risks.
  • Analyze vulnerability data and provide recommendations for continuous optimization of our security posture and assessment workflows.
  • Advocate for security by teaching engineers and stakeholders how to integrate security into their daily workflows.
  • Collaborate cross-functionally by working closely with engineering and DevOps teams to reduce friction and integrate security into development processes.
  • Creatively think out of the box to identify and design improvements and automation in our team processes.

Who You Are

You're a kind, passionate, and collaborative problem-solver who values the opportunity to think beyond the way things are. You are an empathetic communicator who understands the impact of your work on both technical teams and the broader mission.

  • You have at least 2–4 years of experience in security engineering or vulnerability management.
  • You have a proven track record of coordinating between diverse teams with conflicting priorities to achieve successful outcomes.
  • You possess excellent interpersonal communication skills and the ability to navigate complex organizational structures.
  • You have a strong foundation in application security (web security, SAST, SCA) and a general knowledge of cloud architectures and deployment processes.
  • You are able to deal with the ambiguity associated with working in a fast-paced and changing environment.

Extra Credit

  • You have hands-on experience in software development (e.g., Python, Go, or C#/.NET).
  • You have deep experience securing complex IAM policies and cloud-native infrastructure.

Where You Will Work
