• Work collaboratively with Project Managers and stakeholders to ensure assigned tasks are completed accurately, efficiently, and within established project timelines.
• Provide clients with clear and professional status updates, technical guidance, and implementation-related communications throughout project engagements.
• Document all project work, configurations, implementation procedures, network diagrams, technical findings, and deployment outcomes within company documentation systems including IT Glue.
• Maintain accurate project notes, task updates, and time entries within HaloPSA.
• Follow established implementation methodologies, standard operating procedures, and Professional Services best practices.
• Assist with project handoffs, knowledge transfers, internal reviews, and post-implementation support activities.
• Identify project risks, technical concerns, and operational challenges early and communicate them appropriately to stakeholders.
• Support continuous improvement efforts through development of standards, templates, documentation, and repeatable implementation processes.
• Participate as an escalation resource in the company’s on-call rotation for critical after-hours support issues.
• Serve as a point of escalation providing cross-team collaboration with the client services team on technical issues outside of their technical capabilities.
• Act as a technical resource and mentor to junior engineers when guidance or project assistance is needed.

• Identify potential scope deviations, risks, or unforeseen requirements as early as possible.
• Communicate scope concerns promptly to Project Management and leadership teams.
• Avoid unauthorized project expansion (scope creep) without appropriate client approval and internal review.
• Assist in the identification and documentation of potential change-order opportunities when client requests or when technical requirements exceed the approved project scope.
• Maintain a disciplined and professional approach to project execution while helping ensure consistent delivery outcomes and client expectations remain aligned.

Skills, Knowledge & Expertise

• Demonstrated awareness of project scope, including identifying potential scope creep, communicating out-of-scope requests, and supporting appropriate change-order processes when necessary.
• Strong client satisfaction through professional communication, responsiveness, and technical competency throughout project engagements.
• Timely completion of project documentation, including implementation notes, configuration details, technical procedures, network changes, and client-specific knowledgebase updates within IT Glue.
• Prompt and accurate entry of all work performed within HaloPSA, including time entry required for billing, project tracking, forecasting, resource planning, and project performance metrics.
