Principal, Client Delivery & Implementations

About this role

Company Overview

Arcesium is a global financial technology firm that solves complex data-driven challenges faced by some of the world’s most sophisticated financial institutions. We constantly innovate our platform and capabilities to meet tomorrow’s challenges, anticipate the risks our clients encounter, and design advanced solutions to help our clients achieve transformational business outcomes.

Financial technology is a high-growth industry as change and innovation continue to disrupt the status-quo and prompt major transformation. Arcesium is at a particularly interesting time in our own growth as we look to leverage our successfully established market position and expand operations in pursuit of strategic new business opportunities. We value intellectual curiosity, proactive ownership, and collaboration with colleagues, and we empower you to meaningfully contribute from day one and accelerate your professional development.

Position Summary

The Principal, Client Delivery & Implementations owns the end-to-end success of one or more concurrent Arcesium implementation projects for institutional clients. This is a client-leadership role that requires the judgment to navigate complex organizational environments, the credibility to partner with senior stakeholders, and the discipline to drive outcomes when competing priorities and structural complexity create headwinds.

Your client counterparts will be senior operations leaders, CFOs, CTOs, and COOs — accomplished professionals with deep expertise in their own businesses. They are entrusting Arcesium with a consequential technology transformation while continuing to run their operations. Your job is to make that dual burden as manageable as possible by leading the engagement with clarity, foresight, and rigorous execution.

Why This Role Exists

Arcesium’s implementation teams bring deep expertise in the domain (fund accounting, reconciliation, treasury, investor services) and in the product. This role adds a complementary layer: seasoned experience in leading complex client engagements where organizational dynamics, competing priorities, and multi-stakeholder alignment are as important to success as technical execution. You will be the person on each engagement who anticipates how the natural complexity of enterprise transformation will affect the project — and acts on that anticipation proactively.

What You Will Own

• Client Partnership at the Leadership Level. You build and maintain trusted relationships with client executives (COO, CFO, CTO) alongside the day-to-day project team. You establish steering committees and executive touchpoints as forums for shared visibility, ensuring that leadership on both sides has a clear, consistent view of project progress and risks.

• Stakeholder Alignment Across Complex Organizations. You develop a nuanced understanding of each client’s organizational structure, decision-making processes, and internal priorities. You recognize that different stakeholders bring different perspectives shaped by their roles and responsibilities, and you tailor your engagement approach accordingly to build alignment and maintain momentum.

• Expectation Management Across Transitions. You ensure continuity between the sales and implementation phases, taking ownership of aligning what was envisioned with what will be delivered. You manage onboarding of new stakeholders who join mid-project, ensuring they have the context needed to engage productively without losing the ground already covered.

• Documentation as a Shared Asset. You build and enforce a documentation practice where every scope evolution, decision rationale, and priority shift is captured in durable written form. You do this to give both Arcesium and the client a shared, reliable record — because in long-running engagements, institutional memory fades on both sides, and a clear written trail protects everyone.

• Delivery Execution Through the Team. You work through Arcesium’s existing PMO, FDSA, and FDDS staff — coaching them on stakeholder engagement while leveraging their product and domain expertise. You do not replace them; you amplify their effectiveness by providing the senior client-leadership layer that complex engagements demand.

• Go-Live and Transition Leadership. You recognize that the transition to production is a high-stakes moment for client organizations and lead accordingly. You design hyper-care plans that provide visible, steady support during the critical post-go-live period, building client confidence through responsiveness and transparency.

Qualifications

• This section describes what we are evaluating. Titles and years of experience are proxies; the demonstrated judgment below is what matters.

• 10+ years in enterprise software implementation delivery, with at least 5 years in a client-facing leadership role where you were accountable for the outcome, not just the plan. Financial services or fintech strongly preferred.

• Experience leading engagements with diverse stakeholder dynamics — where success required building alignment across stakeholders with different levels of enthusiasm, different priorities, and different relationships to the technology being implemented. You should be able to describe how you built productive working relationships in these environments.

• A track record of managing the transition from sales to implementation. You have taken ownership of aligning client expectations with delivery scope, navigating situations where the two were not fully synchronized, and doing so in a way that strengthened the client relationship.

• Demonstrated commitment to documentation discipline. You maintain rigorous records of decisions, scope changes, and rationale even when the pace of the project makes it tempting to skip. You can describe how this discipline has benefited both your team and your clients in practice.

• Experience with data migration and legacy system transitions in environments where the migrati
