Business Systems Manager

About the role

Decagon is growing fast — we're looking for a Business Systems Manager to own the implementation, deployment, and maintenance of our ERP, and to drive ownership across our broader systems landscape — Ramp, Navan, TeamOhana, Aleph, and more.

This isn't a role about evaluating tools and writing decks. You'll be hands-on, driving the full SDLC across all of these systems while partnering closely with every relevant business stakeholder. You navigate and thrive in ambiguous environments, constantly iterating to get to best-in-class. You move with urgency, with a clear goal: transforming our systems landscape to be as efficient and effective as possible.

Responsibilities

• Own and scale the company’s business systems ecosystem — including ERP, Ramp, Navan, TeamOhana, Aleph, Variabl and other critical platforms
• Oversee systems strategy, architecture, configuration, integrations, access governance, data integrity, optimization, and ongoing administration across the organization
• Design and maintain end-to-end processes across the full financial and operational lifecycle, closing gaps between upstream tools and the ERP through disciplined integration design
• Identify operational bottlenecks across Finance, Accounting, People, and Legal, and deploy automated or AI-powered solutions to reduce manual data entry and error
• Lead the rollout of new tools, features, and system upgrades — training teams, running user acceptance testing, and protecting business continuity along the way
• Partner with Finance, Accounting, People, Legal, and Engineering to translate business requirements into scalable system solutions, and communicate impact — time saved, cost reduced, errors eliminated — back to leadership

Requirements

• 6+ years of hands-on experience administering business systems — ERP, HRIS, spend, and travel platforms
• Hands-on experience with AI-native tools and have used them to automate real workflows — you're already using tools like Claude, Claude Code, or Cursor to build and ship solutions, not just experimenting with them
• Deep expertise in end-to-end finance/accounting workflows — AP, AR, GL, month-end close, and consolidations
• Comfort navigating the build vs. buy decision, and knowing when middleware or an off-the-shelf tool beats a custom build
• Ability to align system architecture and business priorities through strong cross-functional collaboration — building trust quickly with Finance, People, Legal, and every other partner
• Proven ability to independently drive complex projects under ambiguity and deliver results, without needing formal authority to get things done

Qualifications

• Led AI transformation initiatives specifically within G&A or back-office functions — knowing the common failure modes and how to avoid them
• A product mindset: building things people actually adopt and love using, not just automations

Benefits

• Medical, Dental, and Vision benefits for you and your family
• Life Insurance and Disability Benefits
• Retirement Plan (e.g., 401K, pension)
• Parental Leave
• Fertility and family building benefits through Carrot
• Monthly stipend to support your wellness, lifestyle, and work-life balance
• Daily lunches and snacks in the office to keep you at your best
• Take what you need vacation policy (subject to local requirements; UK employees receive 25 days of statutory leave)
