Engineering Manager II - Whatsapp

The role

You will lead the WhatsApp engineering team, which owns onboarding, template management, high-volume message delivery and usage metering. You will set the architecture for scale and reliability and grow a team of 8+ engineers.

What you will do

• Own the high-level architecture and scaling decisions for core Phone platform components, including CPaaS abstractions, provider adapters and shared messaging/voice APIs.
• Own Phone Billing end to end: usage metering, rating, reserve/commit lifecycle, idempotency, reconciliation and audit trails for Phone and WhatsApp.
• Lead the evolution of Trust & Compliance systems into a configuration-driven, rules-based platform.
• Work hands-on with NestJS, Firestore, MongoDB, PostgreSQL, Redis, queuing systems, data warehousing and service mesh microservices.
• Lead cross-cutting work to improve reliability, latency and throughput across time-sensitive APIs and workflows.
• Drive observability and resilience, including monitoring, alerting (Prometheus/Grafana) and incident response.
• Use LLMs and AI tools to write, refactor, test and debug code, with guardrails to reduce hallucination.
• Partner with product, infra, security, finance and legal teams on data integrity, access control and compliance.
• Develop EM I leaders and senior engineers, build a leadership pipeline and succession plans, and raise the hiring bar.
• Take part in design reviews, deep dives and on-call rotations.

Required qualifications

• 9+ years of backend engineering experience
• 2+ years of leadership experience
• Proven track record of designing fault-tolerant systems at a scale of billions of hits or events
• Deep expertise in distributed systems, event-driven architectures and asynchronous job processing
• Experience building systems where correctness is non-negotiable, such as metering, ledgers, billing, payments or comparable transactional domains
• Working grasp of idempotency, exactly-once semantics and reconciliation
• Proven experience optimizing availability, performance and reliability under load
• Strong experience with relational and NoSQL data models, especially complex transactional data
• Experience designing policy- or rules-driven systems that evolve with external requirements
• Familiarity with monitoring, SLOs and root-cause analysis in production
• Familiarity with hallucination mitigation strategies
• Excellent communication and cross-functional collaboration skills, including with Finance, Legal and external partners

Nice to have

• Experience with usage-based billing or metering engines in a high-volume product, managing millions of transactional events per hour
• Exposure to telecom trust and compliance regimes such as 10DLC, toll-free verification, TCPA/TSR, DLT, carrier filtering or number portability
• Experience building provider-agnostic integration layers across multiple third-party vendors
• Experience with AI tools and communication APIs such as Twilio or Plivo
• Contributions to open-source tools, internal platforms or engineering blogs
