Platform Engineer AI Builder

Canada/United States

MaintainX is the world's leading Asset and Work Intelligence platform for industrial and frontline environments. We are a modern IoT-enabled cloud-based tool for reliability, safety, and operations on physical equipment and facilities. MaintainX powers operational excellence for 13,000+ businesses including Duracell, Univar Solutions Inc., Titan America, McDonald's, Brenntag, Cintas, Xylem, and Shell.

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

The way software gets built is changing faster than most companies can keep up with. At MaintainX, we're not waiting to see how it plays out, we're building the infrastructure that puts our developers at the leading edge of it.

We're forming a dedicated team focused on accelerating how our developers build and ship software with AI. The team will develop agentic tooling across the software development lifecycle — starting with autonomous coding agents that can take a ticket, implement the change, and open a pull request, with minimal manual intervention.

In this role, you'll own the infrastructure that makes that possible: reproducible developer environments, containerized sandboxes, agent orchestration, MCP tool integrations, and the observability layer that makes AI agents trustworthy at scale. You'll be a foundational contributor to a system that every developer at MaintainX will rely on.

What you’ll do: 

  • Build and operate the full agent infrastructure stack: isolated dev environments, agent orchestration, and the MCP tool registry that gives agents to internal systems.
  • Design and maintain reproducible developer environments, ensuring dev, CI, and agent environments are identical by construction.
  • Integrate agents with internal and external tooling so agents can be triggered from anywhere and agents have the context they need to act.
  • Instrument agent runs with OpenTelemetry to produce traces of tool invocations, CI outcomes, and failure points, turning AI pipelines from black boxes into observable systems.
  • Establish standards for MCP tool development and agent configuration sharing so teams can author capabilities once and reuse them across repos.
  • Collaborate with product and platform teams as internal customers, running enablement, demos, and office hours to drive adoption of the agent platform.

About you:

  • 4+ years of experience in platform engineering, developer experience, or infrastructure — you've felt the friction of inconsistent environments and flaky CI, and you know how to fix it.
  • Hands-on experience with AI coding tools (Claude Code, OpenCode, Cursor, or similar) and a genuine interest in making agentic workflows your full-time focus.
  • Strong working knowledge of containerization (Docker, Dev Containers) and CI/CD pipelines (GitHub Actions or equivalent).
  • Comfortable with Node.js, TypeScript, Python, or similar.
  • Knowledge about LLM agent frameworks, MCP, or tool-use patterns is a strong differentiator.
  • A product mindset: you build platforms with and for internal customers, not just for yourself.
  • Bonus: you've already shipped an agent integration to production.

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 Optimists.
    • We believe in meritocracy, where ideas and effort are publicly celebrated.

About us:

Our mission is to deliver one platform for maintenance, repair & operations teams to keep the physical world running. We believe the greatest asset in any organization is the people. That’s why we built an intuitive, mobile-first solution to help boost productivity and collaboration across teams and locations.

MaintainX is committed to creating a diverse environment. All qualified applicants will receive consideration for employment without regard to race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

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.
