About us

OneReach.ai is the company behind Generative Studio X (GSX), the agentic orchestration platform for enterprises providing the infrastructure to govern, coordinate, and scale AI agents across their organization.

• Serve as a primary point of contact for clients, facilitating design sessions, progress reviews, and key decision meetings.
• Represent the company during onsite customer and partner meetings.

Requirements

• 5+ years of experience in technical account management or technical project/program management in a software, automation, or technology-driven environment.
• Bachelor’s degree in a technical field (Computer Science, Engineering, or related) or equivalent hands-on experience.
• Demonstrated experience working directly with clients or enterprise stakeholders, balancing delivery execution with relationship management.
• Strong documentation and organizational skills, with experience producing structured internal and external program artifacts such as status reports, risk logs, and delivery dashboards.
• Solid understanding of software development lifecycles, system integrations, and automation architectures.
• Experience translating operational or customer requirements into clear, actionable technical plans.
• Excellent communication, presentation, and stakeholder management skills, with the ability to translate complex technical concepts for non-technical audiences.
• Fluent English (written and spoken).

Nice to Have

• Experience with automation platforms, conversational AI, or SaaS product delivery.
• Previous hands-on experience in a technical or engineering role (e.g., software development, systems analysis, solutions engineering).
• Familiarity with low-code / no-code tools or workflow orchestration systems.
• Experience leading distributed or global delivery teams.

Why Join OneReach.ai

• Shape the future of automation: Contribute to a world-class platform that’s redefining how organizations design, deploy, and scale automation.
• Work with global experts: Collaborate daily with a distributed team of innovators in conversational AI, automation, and user experience.
• Enjoy a flexible, remote work culture with opportunities for professional growth and development.
