Role overview
HighLevel is an AI-powered business operating system supporting SMBs across 150+ countries, helping businesses generate over $7 billion in ecosystem value through centralized conversations, automation and intelligence. With 2,000+ team members across 10+ countries, the company operates as a global, remote-first organization. The Engineering Manager role leads the WhatsApp Team, owning the entire WhatsApp ecosystem including frictionless onboarding, complex WABA management, template lifecycles, high-throughput message delivery, and usage metering for monetization. The position involves re-architecting for massive scale at the intersection of product ambitions and Meta's global business platform, navigating high-stakes environment where roadmap velocity meets technical rigor of massive-scale API integrations.
Responsibilities
- Architect for massive scale: Own the high-level architecture and scaling decisions for core Phone platform components, including CPaaS abstractions, provider adapters, and shared messaging/voice APIs that support billions of monthly events
- Own Phone Billing end to end: usage metering, rating, reserve/commit lifecycle, idempotency, reconciliation, and audit trails for the Phone and WhatsApp channels - with zero tolerance for double-charging or lost usage
- Lead the evolution of Trust & Compliance systems into a configuration-driven, rules-based platform that adapts to new regulatory and carrier requirements without invasive engineering change
- Work hands-on with technologies like NestJS, Firestore, MongoDB, PostgreSQL, Redis, Queuing Systems, Data Warehousing Systems and Service Mesh-based microservices
- Drive high-concurrency innovation: Lead the design and execution of cross-cutting initiatives to improve reliability, latency, and throughput across time-sensitive APIs and workflows serving millions of businesses
- Drive observability and resilience by evolving our monitoring, alerting (Prometheus/Grafana), and incident response strategies - including the financial invariants that must be alerted on, not just the technical ones
- Leverage LLMs and AI tools to write, refactor, test, and debug code efficiently - while implementing guardrails to reduce hallucination and boost reliability
- Partner with product, infra, security, finance and legal teams to ensure data integrity, access control, and compliance across phone services
- Develop EM I leaders and senior engineers, build leadership pipeline, succession planning and raise the hiring bar
- Participate in design reviews, deep dives, and on-call rotations to support a high-bar culture of accountability and operational excellence
Requirements
- 9+ years of backend engineering experience with 2+ years of leadership, with a proven track record of designing fault-tolerant systems that operate at a scale of billions of hits or events
- Deep expertise in distributed systems, event-driven architectures, and asynchronous job processing
- Demonstrated experience building systems where correctness is non-negotiable - metering, ledgers, billing, payments, or comparable transactional domains - with a working grasp of idempotency, exactly-once semantics, and reconciliation
- Proven experience optimizing availability, performance, and reliability in real-world systems under load
- Strong experience with relational and NoSQL data models (especially with complex transactional data)
- Experience designing policy- or rules-driven systems that evolve with external requirements rather than hard-coding them
- Familiarity with monitoring, SLOs, and root-cause analysis in production environments
- Familiarity with hallucination mitigation strategies (e.g., code constraints, test scaffolding, embeddings, context injection)
- Excellent communication and cross-functional collaboration skills, including with Finance, Legal and external partners
- A pragmatic, hands-on leader who balances long-term vision with iterative execution
Nice to have
- Experience with usage-based billing or metering engines in a high-volume product, specifically managing millions of transactional events per hour
- Exposure to telecom trust and compliance regimes - 10DLC, toll-free verification, TCPA/TSR, DLT, carrier filtering or number portability
- Experience building provider-agnostic integration layers across multiple third-party vendors
- Experience working with AI Tools, Communication APIs (Twilio, Plivo etc)
- Contributions to open-source tools, internal platforms, or engineering blogs
Benefits
- Global, remote-first organization
- Operate at the intersection of cutting-edge product ambitions and Meta's global business platform
- Navigate high-stakes environment where roadmap velocity meets technical rigor of massive-scale API integrations
- Solve for extreme deliverability under bursty load, resilient webhook ingestion, and ironclad tenant isolation
- Lead a world-class team of 8+ engineers
- Own the technical destiny of a product that is scaling faster than the market
