WHO YOU ARE:

We are hiring a Senior Technical Product Manager for a highly visible, client-facing role. You'll lead the API build and client onboarding and implementation, from technical kickoff through production go-live, and partner with Sales and Pre-Sales to win and launch business.

This is a high-impact role for a hands‑on product manager. You'll define and own the technical requirements, including API design, data models, event‑driven integrations, and traffic management policies such as rate limiting and throttling. You'll bring the technical depth to shape architecture decisions with specificity, not just business cases. When integrations break, you'll dive deep with engineering to find the root cause and drive the fix.

You’ll serve as the technical voice our clients can trust. You'll lead integration design sessions with client architects and technology leaders, turn their requirements into plans your engineering teams can execute, and see those plans through production. You'll write concisely and present complex technical topics with equal clarity to engineers and senior executives.

WHAT YOU'LL DO:

• Write clear, testable product requirements, API specifications (OpenAPI), and acceptance criteria. Drive the SDLC across design, build, test, release, and post-release validation.
• Own and execute client onboarding and implementation end to end, from technical kickoff and integration design through UAT, production readiness, and go-live.
• Serve as the senior technical subject matter expert and point of contact for client engineering, architecture, and security teams. Lead integration design sessions and translate client needs into executable plans.
• Partner with Sales and Pre-Sales as the technical lead on API‑led opportunities, including discovery, solution design, live demos, and RFP and security questionnaire responses.
• Partner with architects and engineering leads on platform architecture, service boundaries, and scalability trade‑offs. Define and review data models and canonical schemas across APIs, events, and persistence layers.
• Define requirements for event‑driven integrations, including Kafka topic and event schema design and webhook payloads, retries, and signing.
• Define API traffic management and access policies, including rate limiting, throttling, quotas, IP whitelisting, and OAuth 2.0 and API key provisioning.
• Own requirements for reference data structures, the reference data engine (RDE), and integrations with document management systems.
• Dive deep with engineering on production issues and client escalations to identify root cause, drive resolution, and keep clients informed.
• Drive execution across large, geographically distributed engineering and QA teams. Establish mechanisms such as release readiness reviews and go/no‑go gates, and report on release predictability, quality, and SLA adherence.
• Build a repeatable onboarding playbook and continuously reduce time to go-live by turning recurring integration friction into product requirements and documentation.
• Bring structured client and field feedback to product leadership to inform roadmap priorities.
