About Cala

At Cala, we’re working to free people from the burden of chronic disease. We began by creating the first non-invasive prescription therapy for hand tremor. After years of careful fine-tuning and improvements, we released Cala kIQ — our most sophisticated therapy yet. Our products have empowered thousands of people to get back to their lives with confidence and ease.

But we won’t stop there. Our pioneering technology can be applied across neurology, cardiology, and so much more. It’s all part of our mission to help people in their struggle with chronic disease. We’re only just getting started.

A Day in the Life

Vulnerability & Dependency Management

  • Monitor and manage open-source and third-party dependencies using Software Composition Analysis (SCA) tools to identify and mitigate supply chain risks.
  • Track and prioritize Common Vulnerabilities and Exposures (CVEs) affecting our tech stack.
  • Collaborate with development teams to automate dependency updates and integrate security scanning into the CI/CD pipeline.


Penetration Testing & Vulnerability Assessment

  • Manage end-to-end scope, execution, and tracking of external Penetration Tests and bug bounty programs.
  • Analyze penetration testing reports, validate findings, and translate complex technical vulnerabilities into actionable remediation plans for engineering teams.
  • Conduct internal vulnerability scanning and architectural risk assessments.


Security Remediation & Engineering

  • Own and drive security remediation tasks across infrastructure, networks, and applications.
  • Provide hands-on technical guidance and code/configuration reviews to developers to ensure secure coding practices are met.
  • Implement security controls and guardrails (e.g., IAM policies, network segmentation, secrets management) to proactively reduce our attack surface.

Incident Response & Threat Hunting

  • Serve as a core member of the Incident Response (IR) team, participating in an on-call rotation to detect, contain, and eradicate security incidents.
  • Analyze security logs (SIEM, EDR, cloud provider logs) to investigate potential breaches or anomalous behavior.
  • Conduct post-incident reviews (root-cause analysis) and document lessons learned to continuously harden our defenses.


Resilience & Preparedness (Tabletop Exercises)

  • Design, facilitate, and execute regular security tabletop exercises for both technical teams and executive leadership.
  • Develop realistic threat scenarios (e.g., ransomware, supply chain attacks) to test the efficacy of our incident response plans and identify gaps in communication or tooling.


Additional Responsibilities

  • Cloud Security Posture Management (CSPM): Monitor and secure cloud infrastructure (AWS/GCP) configurations to prevent drift and misconfigurations.
  • Security Metrics & Reporting: Define, track, and report on key security performance indicators (KPIs) like Mean Time to Remediate (MTTR) and patch compliance.
  • Compliance Support: Assist in gathering evidence and maintaining controls for security frameworks and certifications (e.g., SOC 2, ISO 27001, HIPAA).
  • Security Awareness: Champion a security-first culture by mentoring junior engineers and creating targeted security training content.

Qualifications & Skills

Required Experience

  • Bachelor’s degree in Computer Science, Software Engineering, or a related technical field
  • 3+ years of experience in Security Engineering, Application Security, or Incident Response.
  • Hands-on experience with modern security tooling (e.g., Snyk, Dependabot, Burp Suite, Splunk, Datadog).
  • Strong understanding of OWASP Top 10, CWE, and cloud security best practices.
  • Hands-on experience with CI/CD pipelines and build automation tools (e.g., Jenkins, GitHub Actions, GitLab CI) to integrate security scanning and controls.
  • Proficiency in Python and Shell scripting (Bash) to automate security workflows and build security tooling.


Preferred Qualifications

  • Familiarity with additional programming languages such as Go, JavaScript/TypeScript, or Rust for deeper code reviews and custom tooling.
  • Experience securing cloud-native environments (Docker, AWS/GCP) and native AWS security tools (AWS Inspector, GuardDuty).
  • Hands-on experience with GRC platforms (e.g., Vanta).
  • Familiarity with Infrastructure as Code (IaC) security scanning (e.g., Checkov, TFLint).
  • Relevant industry certifications (e.g., CISSP, CEH, OSCP, GCIH, AWS Certified Security).
  • Excellent communication skills with the ability to articulate technical security concepts to non-technical stakeholders.
  • Familiarity with bug bounty services like BugCroud.
  • Experience working on cloud connected IoT devices (provisioning, key rotation, OTA update security).

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 07/31/2029

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
