ABOUT THIS ROLE

We're hiring a Senior Platform Product Manager to own two of our most critical platform areas: our API gateway and our observability platform.

The API gateway is the public entry point for all Apex APIs, handling hundreds of millions of requests per month (and growing). Observability is the foundation for how we monitor and report on that traffic.

What You'll Own

• End-to-end product strategy and roadmap for both platform areas
• Core API gateway capabilities including traffic management, rate limiting, and logging
• Standards and experience for metrics, logs, traces, alerting, dashboards, and operational reporting (powered by Datadog)

What You'll Do Day-to-Day

• Set a clear product vision for both platform areas and translate it into multi-quarter and multi-year roadmaps
• Partner with engineering leaders across two teams to shape priorities, drive execution, and unblock delivery
• Balance client commitments, commercial opportunity, technical health, security/compliance needs, and unplanned demand
• Define measurable outcomes and use them to guide prioritization
• Write crisp requirements and strategy documents that scale across engineering and senior leadership
• Maintain a healthy Jirabacklog and communicate progress proactively

What We’re Looking For

• 5+ years of product management experience, with a track record of owning cloud platform infrastructure
• Good understanding of API concepts - latency, rate limiting, response codes
• Experience with Datadog or comparable observability tooling
• Demonstrated ability to set product vision and strategy, and communicate it credibly to technical and non-technical stakeholders
• Excellent prioritization judgment in ambiguous, high technical areas
• Strong written communication: specs, strategy docs, and proposals that stand on their own with both technical and executive audiences

Nice to Have

• Experience with API gateway platforms (Apigee, Kong, AWS API Gateway, or similar)
• Fintech or financial infrastructure experience
