Forward Deployed Engineer

About the role

Forward Deployed Engineers sit between our clients and our platform. You will embed with client teams, understand the real problem behind the requirement, and build the solution yourself on ServiceNow, working alongside SN Architect, our eight-agent delivery workflow. You own the outcome from discovery through go-live, and what you learn in the field shapes the tools and patterns the rest of MainStack uses.

What you'll do

• Embed with client teams to understand their processes, data, and constraints, and turn them into clear technical designs.
• Build and configure ServiceNow solutions across ITSM, CMDB/CSDM, ITOM, CSM, and Now Assist.
• Direct AI agents through discovery, build, test, and documentation, and keep human review at every gate.
• Build integrations, scripts, and automations that hold up in production.
• Feed field insights back into SN Architect and our delivery playbooks.

What we're looking for

• Hands-on experience building on the ServiceNow platform (scripting, flows, integrations, data model).
• Strong JavaScript skills and comfort working with REST APIs and integration patterns.
• Confidence working directly with client stakeholders, from engineers to senior leaders.
• An ownership mindset: you would rather ship a working solution than hand over a document.
• Fluent written and spoken English.

Nice to have

• ServiceNow certifications (CSA, CAD, or a Certified Implementation Specialist track).
• Experience with LLMs, AI agents, or Now Assist.
• Consulting or client-facing delivery background.
