Our Origin Story in a Nutshell

KeyCaliber was founded by a former Executive Office of the President and Department of Homeland Security security leader who saw the same pattern across organizations: security spending kept increasing, but security outcomes did not. Companies layered on more products, and expanded their budgets—yet they remained exposed because their fundamentals weren’t solid. Critical assets were overlooked. Controls were inconsistently applied. Gaps remained hidden—not from lack of effort or investment, but from lack of visibility into what was truly protected.

No amount of spending can mature, scale, or strengthen a security program if the foundation is shaky.

KeyCaliber’s mission is to give organizations the sturdy foundation they need. When the fundamentals are properly addressed, every dollar spent becomes more effective, every control becomes more consistent, and the entire security program becomes more resilient, efficient, and proactive.

Careers

  • We are looking for an experienced full-stack software engineer who ships code, not someone who needs a committee to approve a button color. You'll take ambiguous problems and turn them into working code in days, not quarters.

    You'll split time between:

    • Data pipeline (~50%)

    • Front-end features (~40%)

    • Back-end API (~10%)

    Required skills:

    • Python

    • PostgreSQL

    • Redis

    • Argo Workflows

    • Kubernetes/Docker/Helm

    Requirements:

    • Experienced - With at least 3 years of hands-on work

    • Self-directed - Figure out the problem, propose a solution, build it. Don't wait to be told what to do.

    • Fast - We'd rather have a reasonable solution Tuesday than a perfect one never. You can refactor later.

    • Pragmatic - Know when to build quick and when to build right. Most of the time it's both.

    • Comfortable with ambiguity - Requirements will be "make it show the coverage gaps somehow"

    • Full stack capable - Strong in either Python or React, competent in the other

    Nice to have:

    • Cybersecurity domain knowledge

    • Experience with data pipelines (Spark, Airflow, similar)

    • Kubernetes familiarity

    • Worked at a startup before (or want to)

    Not a fit if:

    • You need detailed specs before writing code

    • You prefer tickets with story points and sprint ceremonies

    • You're uncomfortable deploying your own code

    • You want someone else to handle "the other half" of the stack

    Location:

    • Maryland, US. No remote work from a different state or country.
