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.

Building AI agents is no longer the challenge. Connecting them into a coordinated, governed system is. GSX is that infrastructure. A strategic control plane that governs how agents coordinate, how they operate as one system, and how that system grows to deliver outcomes no individual agent could produce alone.

Founded by Robb Wilson, author of Age of Invisible Machines, OneReach.ai exists precisely at the gap between AI potential and AI value. Will you join us?

In this role, you'll serve as a trusted advisor who aligns technical strategy with business goals while owning planning, execution, and delivery of your portfolio of accounts.

You'll work closely with the team to build a strong understanding of the customer's actual problem, not just the spec. This is a communication-heavy role; things stall when updates don't flow both ways.

There's no rigid playbook here - the team operates with a flat, collaborative culture where decisions get made together, without hierarchy, and people are expected to speak up when they have questions.

What You’ll Do

• Lead planning and delivery of multiple concurrent projects, ensuring alignment with customer goals and organizational priorities.
• Build expertise in the OneReach.ai Communication Studio and related technologies (Voice, SMS, NLU, low-code/no-code).
• Develop and maintain account roadmaps, ensuring visibility, accountability, and clear progress reporting across stakeholders.
• Ensure all technical and business requirements are properly gathered, validated, and communicated to implementation teams.
• Identify and manage interdependencies, risks, scope, and resources across teams to ensure on-time, high-quality delivery.
• Collaborate with delivery, product, and growth teams to align on priorities, timelines, and deliverables.
• 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.

About the product

We’re building Rendi, a mobile app for language learning. The core idea is that the lessons are connected into a single story with recurring characters: the main character, a little star named Rendi, finds herself in a world of differently shaped figures, where she has to learn their language and understand how they live. The learning experience is structured like a text-based visual novel: every grammar or vocabulary topic emerges from Rendi’s interactions with the characters. The lessons combine explanations, exercises, and practice, including AI-powered activities.

What we’re promoting

We are launching paid user acquisition for Rendi. The main channels are Meta (Instagram / Facebook) and TikTok, followed by Google and Apple Search Ads. The goal is app installs and waitlist sign-ups in European markets, primarily among expats. We discuss the creatives (UGC videos, static ads) together and produce them in-house.

What you’ll do

• Set up and manage advertising campaigns in Meta Ads and TikTok Ads (later - Google / Apple Search Ads)
• Build and test combinations of audiences, creatives, and offers
• Run campaigns for app installs, waitlist sign-ups, and leads
• Run A/B tests, scale what works, and cut what doesn’t
• Track the metrics that matter (CPI, CPA, CTR, ROAS) and keep clear reporting
• Work with the team to verify tracking (Meta Pixel / CAPI, events, attribution)

We’ll work well together if you

• Have independently launched and managed campaigns in Meta Ads and TikTok Ads (mobile apps / subscriptions are a big plus)
• Understand the funnel and unit economics: CPI / CPA / ROAS, payback, impact on LTV
• Make data-driven decisions
• Familiar with app tracking (Meta CAPI, MMPs such as AppsFlyer / Adjust are a plus)
• Understand the specifics of advertising in European / English-speaking markets

Terms

• Remote, project-based / part-time
• Work directly with the founder and the team's marketer
• Budgets and compensation - negotiable

How to apply

Send a short introduction about yourself + 2-3 case studies with numbers: what the project was, which platform, the scale of the budget, what the metrics were, and how you moved them.
