About the Team:

This team is responsible for the speed, stability, and operational health of HighLevel. We partner across Backend, SRE, Infrastructure, Messaging, CRM, and Automations teams to ensure the platform runs smoothly under unpredictable workloads and global traffic patterns.

Our mandate is to detect issues early, eliminate bottlenecks at the root, and build infrastructure that stays reliable years into the future.

About the Role:

We’re hiring a Senior Backend Engineer who is passionate about performance optimisation, distributed systems behaviour, runtime efficiency, and platform-level correctness. You won’t just tune endpoints—you’ll design systems and patterns that prevent slowness before it begins.

This is a hands-on engineering role with broad influence across services, architecture decisions, and operational standards. You will work with high-traffic systems, complex micro-services, and global workloads where milliseconds matter.

Improve performance and reduce latency:

Come up with architectural planning for implementing new features around custom objects

Diagnose and remove bottlenecks in backend services, APIs, and message flows

Profile Node.js services (CPU, heap, event loop) and rewrite hot paths for efficiency

Strengthen platform reliability:

Improve resilience via batching, caching, pooling, concurrency controls, and backpressure

Harden services against cascading failures and dependency slowness

Establish rate-limiting, queueing, and circuit-breaker patterns that scale under load

Optimize database queries, indexing strategies, denormalization, and read/write paths

Collaborate on infrastructure & operations:

Work with SRE and Infra teams on autoscaling, capacity planning, quotas, and workload efficiency

Contribute to runtime configuration improvements (GKE, Node.js, Redis, Pub/Sub, Firestore, ClickHouse)

Participate in performance incident reviews and drive actionable root-cause fixes

Build long-lasting performance frameworks:

Define best practices for high-performance microservices, distributed patterns, and observability

Create reusable performance tooling, dashboards, and profiling workflows

Mentor engineers on writing scalable code, interpreting metrics, and designing reliable services

7+ years of backend engineering experience focused on large-scale systems.

Strong experience with Node.js internals (event loop, memory model, async behavior)

Proficiency in diagnosing performance issues using CPU/heap profilers, tracing, and metrics

Solid understanding of Microservices, Distributed systems, High-throughput APIs, Caching strategies, Queuing/Backpressure patterns & Rate limiting/load balancing

Experience with MongoDB, Postgres/MySQL, Firestore, Redis, ClickHouse, or similar DBs

Familiarity with Kubernetes, GCP/AWS, and observability tooling (Grafana, Prometheus, OpenTelemetry)

Possess strong communication skills & are able to explain bottlenecks clearly without finger-pointing

A mindset that treats every millisecond, query, and allocation as something to optimize thoughtfully

Experience with high-traffic Node.js services serving millions of requests/hour.

Familiarity with distributed tracing (OTel), tail sampling, RED/USE metrics, and SLO-driven engineering

Experience preventing and mitigating cascading failures at scale

Background in runtime optimization, capacity planning, or SRE-style operational excellence

Contributions to internal performance frameworks, profiling tools, or reliability toolkits
