Senior Platform Developer, AI Builder

MaintainX is the world's leading AI-powered maintenance and asset management platform, serving 14,000+ customers including Duracell, Shell, Cintas, and Brenntag. We raised $150M in Series D funding led by Bessemer Venture Partners and Bain Capital Ventures, bringing our total funding to $254M. We were named to the Forbes 2025 Cloud 100, the definitive ranking of the top 100 private cloud companies in the world. We're growing fast and hiring the talent to match.

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 development, 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.
