We recently completed a $150 million Series D round, bringing our total funding to $254 million and valuing the company at $2.5 billion.

MaintainX’s mission is to be the go-to work execution platform for manufacturers across Maintenance, Operations, and Safety. Our Security Team plays a critical role in enabling this mission by ensuring the integrity, confidentiality, and availability of our systems, data, and products.

We are looking for a Product Security Developer to join our growing Security Team. This role is a hands-on engineering position focused on designing, building, and integrating security solutions across the MaintainX stack. You will collaborate with multiple product and infrastructure teams to embed security into everything we build and operate.

As part of the Security Team, you’ll report to the Security Lead and work on initiatives that improve the overall security posture of MaintainX, from secure coding practices and internal tooling to automation and vulnerability management.

What You’ll Do:

  • Design and implement security-focused features across our stack (TypeScript, React, Node.js, GraphQL, AWS) in collaboration with product, platform, and DevOps teams.
  • Develop internal security tooling to automate vulnerability detection, dependency management, and compliance validation.
  • Perform secure code reviews and contribute to improving developer security awareness through tooling and education.
  • Integrate security scanning and observability tools into CI/CD pipelines to ensure continuous protection and visibility.
  • Contribute to incident response and threat modeling efforts, helping to identify risks and propose mitigations at the application and infrastructure layers.
  • Collaborate with engineering and infrastructure teams to implement secure-by-design patterns and strengthen authentication, authorization, and data protection mechanisms.
  • Continuously evaluate and enhance the security architecture for MaintainX’s cloud environment.
  • Contribute to security documentation, playbooks, and standards that align with our compliance frameworks (SOC 2, ISO 27001, etc.).

About you:

  • 3+ years of professional software development experience with TypeScript, Node.js, and web technologies.
  • Experience developing or integrating security solutions (e.g., SAST/DAST, vulnerability management, authentication systems, secrets management, identity services).
  • Strong understanding of web application security principles (OWASP Top 10, secure session handling, input validation, XSS/CSRF prevention).
  • Familiarity with cloud security concepts (IAM, network segmentation, encryption, logging).
  • Ability to write maintainable, testable, and secure code.
  • Strong communication skills and ability to partner with product, engineering, and compliance teams.
  • Demonstrated experience working in fast-paced, modern cloud environments.

Nice to Have

  • Experience with React Native and/or GraphQL security considerations.
  • Knowledge of AWS security services (IAM, KMS, GuardDuty, WAF, etc.).
  • Familiarity with DevSecOps pipelines and CI/CD automation (GitHub Actions, CircleCI).
  • Prior experience contributing to or leading security automation or hardening initiatives.
  • Certifications such as OSCP, CSSLP, or AWS Security Specialty are a plus.

What’s in It for You

  • Competitive salary and meaningful equity opportunities.
  • Healthcare, dental, and vision coverage.
  • 401(k) / RRSP enrollment program.
  • Take what you need PTO.
  • A Work Culture where:
  • You’ll work alongside folks across the globe that reflect the MaintainX values, Smart Humble Optimist.
  • We believe in meritocracy, where ideas and effort are publicly celebrated.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

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.
