Apex is seeking a Senior Product Manager to lead the Client Platforms and Configuration product suite within Ascend. This is a strategic role at the heart of Ascend's growth: you will own the configuration layer that underpins every product team's ability to deliver firm‑specific, market‑specific, and jurisdiction‑specific capabilities to our clients.

You will be responsible for the ongoing evolution of Client Configuration and provisioning, serving as the central product manager for how firms are set up, configured, and managed across the Ascend platform. You will partner with product teams across the organization to facilitate their domain‑specific configuration needs while leading the design and delivery of a new firm‑level configuration architecture that will power Ascend's ambitions and support increasingly complex multi‑market, multi‑entity, and multi‑jurisdictional requirements.

This role requires a strategic thinker who can balance the operational demands of a production platform serving millions of accounts with the forward‑looking architecture needed to scale Ascend significantly beyond its current scope.

• Define and own the Client Platforms and Configuration vision and multi‑quarter roadmap within Ascend, balancing operational reliability, product team enablement, and platform scale.
• Lead the strategic initiative to design and deliver a firm‑level configuration layer that supports international expansion, multi‑jurisdiction requirements, and increasingly complex client structures.
• Prioritize initiatives using data‑driven insights, client feedback, and cross‑team dependencies to maximize platform scalability and onboarding efficiency.
• Build business cases with clear outcomes, investment, and ROI; align stakeholders around priorities and trade‑offs.

• Serve as the central product partner for domain product teams (Trading, Investor Communications, Billing, Cash Management, Account Services, etc.), enabling them to define and manage their domain‑specific configuration within a unified framework.
• Establish standards, patterns, and self‑service capabilities that allow product teams to extend configuration without creating fragmentation or technical debt.
• Define and maintain the configuration data model that governs firm‑level settings, product entitlements, feature flags, and domain‑specific parameters.
• Facilitate cross‑team alignment on configuration schema, validation rules, and dependency management.

• Define RESTful APIs and event models for client configuration, provisioning, entitlements, and firm management; ensure excellent developer experience, documentation, and sandbox coverage.
• Partner with engineering on data integrity, observability, and resiliency to support a configuration layer that underpins all Ascend services.
• Establish SLOs for configuration propagation latency, accuracy, and availability; instrument monitoring and alerting for end‑to‑end reliability.

• Own and continuously improve the client onboarding experience, reducing time‑to‑live and manual intervention required to provision new correspondent firms.
• Define and monitor KPIs such as onboarding cycle time, configuration error rate, provisioning success rate, time‑to‑propagation, and self‑service adoption.
• Lead continuous improvement through automation, validation…
