OneStream Planning Architect

Job Title: OneStream Planning Architect

Location: United Kingdom

Henderson Drake is partnering with a Diamond-level OneStream consultancy to appoint a Planning Architect with the technical depth and delivery experience to shape planning solutions from the ground up.

You'll bring a level of OneStream expertise that goes beyond configuration, someone who can make considered architectural decisions across planning, budgeting, and forecasting workstreams, articulate the rationale to senior stakeholders, and provide the technical backbone that delivery teams can build around with confidence.

What you will be doing

• Define and own the technical architecture across OneStream planning engagements, from initial design through to delivery
• Translate complex planning, budgeting, and forecasting requirements into scalable, maintainable OneStream solutions
• Navigate driver-based modelling, workforce planning, and complex allocation requirements from the outset
• Set technical standards and design patterns for delivery teams to work within
• Engage senior client stakeholders on solution design, platform strategy, and long-term planning roadmap decisions
• Identify and resolve architectural risks early, before they become delivery problems
• Support pre-sales and scoping activity, providing technical credibility at the earliest stage of an engagement
• Mentor and guide consultants across the practice on OneStream planning best practice
• Guide clients through UAT, validation, and transition to business-as-usual

What you will bring

• Deep hands-on OneStream experience across planning, budgeting, and forecasting in complex client environments
• A track record of owning architectural decisions on large-scale EPM planning programmes
• Confidence handling driver-based models, complex hierarchies, and multi-dimensional planning challenges without needing to escalate the fundamentals
• Strong communication skills, capable of translating technical design into language that resonates with finance stakeholders
• Experience providing technical leadership across delivery teams without losing sight of the commercial and client context
• The ability to manage project teams and senior client relationships simultaneously
• Confidence making design calls and standing behind them under scrutiny

Why this opportunity

• Work with a Diamond-level OneStream partner on planning programmes where architecture genuinely matters
• Full lifecycle ownership, from initial scoping through to a clean client handover
• Direct influence over how planning solutions are designed and how the practice evolves its delivery standards
• A consultancy that invests in its technical community rather than treating architecture as an afterthought
• Growing demand for senior OneStream planning expertise as finance functions move away from legacy tools towards more agile, integrated platforms
