Senior Platform Engineering Manager - AI-Driven Reliability

The Opportunity

Every product surface at Hinge Health—the ones helping 18M+ people move beyond pain—depends on the foundational infrastructure your team will own. As Senior Engineering Manager, Service Enablement, you'll lead the platform-minded team responsible for keeping our cloud infrastructure rock-solid while accelerating the shift to AI-native engineering workflows. Your work will be a force multiplier for every engineer, product manager, and designer in the company.

This is a high-impact leadership role for someone who thrives at the intersection of platform reliability, developer enablement, and autonomous AI-driven operations

What You'll Accomplish

In your first 3 months:

• Establish relationships with key stakeholders across Security, Product Engineering, Data Engineering, and the India-based SRE team. Audit the current infrastructure posture, on-call practices, and CI/CD pipelines to identify the highest-leverage improvement opportunities.
• Assess your team of 8–10 engineers (Staff, Senior, and mid-level SREs), understand individual growth trajectories, and begin shaping a coaching-first operating cadence.

• Own Platform Reliability & Scalability — Guarantee stability and performance across multiple EKS clusters, maintaining 99.9%+ uptime while optimizing cost-efficiency as AI workloads scale.
• Drive the Harness Engineering Initiative — Define safety rails, test harnesses, and verification systems that allow autonomous AI agents to reliably build, test, and maintain infrastructure in production-grade environments.
• Scale the NestJS Monorepo & CI/CD Platform — Accelerate migration of all NestJS services into the monorepo, ensuring NX, Git Hub Actions, and Okteto deliver a world-class developer experience.

• Execute Vendor Strategy & Cost Optimization — Own relationships with AWS, Datadog, Cloudflare, Temporal, and Infisical; deliver significant cost savings as Hinge Health scales infrastructure and AI workloads.
• Champion Operational Excellence — Run a follow-the-sun support model, maintain 24/7 on-call coverage, lead the Incident Review Board, and continuously improve SLOs, runbooks, and observability to reduce MTTR.
• Build a High-Performing, Inclusive Team — Develop talent toward Senior and Staff levels, maintain sustainable on-call practices, and foster a culture of blameless retros and continuous improvement.

• A Platform Thinker — You see infrastructure as a product. You obsess over developer experience metrics (DXI, DORA, PR throughput) and build systems that reduce friction for every team you serve.
• AI-Forward — You're energized—not threatened—by the shift to AI-assisted engineering. You've experimented with tools like Cursor, Claude Code, or Copilot and can envision a world where engineers act as architects and auditors of AI-generated code.
• A Trust Builder — You communicate effectively across engineering, security, product, and executive stakeholders to align infrastructure decisions with business priorities.
• A Learn-it-All — You don't have all the answers, but you have a proven framework for finding them. You lead blameless retros that convert insights into action and measure what matters most.
• Hands-On & Accountable — You know the ins and outs of your team's tech stack and spend ~15% of your time working in the code. You take owner-operator pride in supporting production systems.
• Resilient — You thrive in fast-paced, ambiguous environments and can make results happen even with imperfect data—whether that's navigating a breaking-change migration at scale or an unexpected incident.

• At minimum, 3-4 years of professional experience in technology, with depth in SaaS platforms and large-scale distributed systems.
• At minimum, 3-4 years managing engineering teams of 6+ direct reports
• Bachelor’s Degree (or equivalent) in Computer Science, Engineering, or a related technical field.
• Deep hands-on expertise with cloud infrastructure (AWS), container orchestration (Kubernetes/EKS), and Infrastructure as Code (Terraform).
• Proven track record owning platform reliability at scale — including incident management, SLO-driven operations, and cost…
