Senior Business Transformation Manager, Finance Transformation

Do you want to be a part of the clean energy movement? Are you passionate about improving our environment for this generation and those to follow? Are you ready to take on new challenges and collaborate with a future-focused team leading the way into new markets? Join Nexamp! This is where you can learn from industry leaders and become one yourself. It's fast-paced, mission-based work that challenges the status quo. Be on the team that's changing the world. What we’re looking for: Nexamp is looking to hire a Senior Business Transformation Manager, Finance Transformation. In this role, you will lead a multi-year portfolio of cross-functional initiatives that improve the scalability, reliability, control, and decision-readiness of Nexamp’s Finance ecosystem. Accounting will be the initial anchor for this work, with the portfolio extending across critical Finance interfaces such as Treasury, FP&A, Tax, Legal, Project Finance and Capital Markets, Asset Management, and selected business units. You will lead defined workstreams from discovery through future-state design, implementation, adoption, measurement, and transition to the teams that will own the work day to day. This is an implementation-oriented role for someone who can connect Finance domain knowledge with operating-model design, process improvement, systems enablement, and change management. You will own the transformation work—not the Finance functions’ line-management responsibilities—and will be accountable for measurable, sustainable improvement rather than recommendations alone. This role supports hybrid work out of our Boston, Chicago, or Washington, D.C. offices. You will report to the Director, Operations Enablement and work closely with Finance leadership and cross-functional partners. What you’ll do: • Own the Finance transformation portfolio by building and maintaining an integrated roadmap across Accounting and critical Finance interfaces. Sequence work based on risk, value, effort, dependencies, and organizational capacity; define problem statements, outcomes, decision rights, milestones, and success measures; and maintain the implementation backlog, dependency log, decision log, and executive reporting rhythm. • Lead complex Finance transformation workstreams end to end, from problem framing and current-state diagnosis through future-state design, implementation, adoption, measurement, stabilization, and transition. Escalate unresolved trade-offs and sponsor misalignment so decisions are made at the right level. • Convert existing process documentation, current-state maps, and capability work into implementation. Validate findings through interviews, walkthroughs, transaction and reporting samples, data analysis, and direct observation. Distinguish root causes from symptoms and local process issues from enterprise operating-model issues. • Apply Lean, Six Sigma, continuous improvement, and organizational design methods to redesign Finance workflows, roles, handoffs, decision rights, review points, escalation paths, controls, and backup coverage. Establish practical target-state frameworks for month-end, quarter-end, and year-end close and reporting without adding unnecessary bureaucracy. • Connect financial architecture, controls, data, and technology across legal entities, projects, ownership structures, financing arrangements, tax-equity structures, intercompany relationships, consolidations, reporting dimensions, and technical-accounting judgments. • Partner with Product & Technology and Finance system owners to optimize NetSuite and connected systems, including integrations, reporting, data quality, workflow configuration, and controlled automation.
