Full Stack Builder - Email Builders Team

About the Role:

The traditional model of siloed product managers, designers, and engineers is too slow for modern AI-native development. At HighLevel, every engineer owns a product outcome end-to-end, from idea to prototype to production to scale. You will operate as a Team of One. With AI tooling and strong engineering infrastructure, a single engineer can now build what previously required an entire squad. You are not implementing tickets. You own the product.

What You’ll Do

Feature/Module Ownership:

• Translate business goals into working, deployable systems

• Propose architecture, workflows, and implementation plans for assigned modules/features; refine and finalize through review with Tech Leads and Engineering Managers before execution

• Own modules end-to-end — from design discussion through release, post-launch stability, and iterative improvements

Rapid Prototyping & Iteration:

• Turn ambiguous ideas into working demos quickly, with timelines scoped to complexity

• Prototype using code, AI tooling, automation, or low-code systems

• Validate through experiments and real user feedback, then iterate to production quality

• Integrate email statistics and analytics with internal teams, and drive feature attribution and metrics visibility so a release is measurable on our dashboards.

Scale, Performance & Reliability:

• Build and maintain the Email Template Builder web app — a system powering 30M+ emails/day, directly impacting scalability (throughput at peak load), reliability (uptime and send success rate).

• Optimize frontend rendering performance, component architecture, lazy loading, and state management; tune backend queries, caching (Redis/CDN), and latency at scale.

• Reason through token consumption, inference cost, and infrastructure tradeoffs when integrating AI/LLM tooling

Operational Excellence:

• Instrument systems with monitoring and telemetry

• Build evaluation loops for continuous quality improvement

• Automate workflows that increase engineering velocity

• Maintain clear, repeatable documentation

Tech Stack, You’ll Work With

• Frontend: Vue.js, JavaScript/TypeScript, HTML5, CSS3 (Tailwind/SCSS)

• Backend: Node.js, NestJS

• Data: MongoDB, Firestore, Clickhouse, Redis

• Infra: GCP(Pub/Sub, K8s) Cloudflare

• AI: LLM APIs, LangGraph, AI-aided dev tooling

• Tooling: Git, Jenkins, observability stack(Grafana)

You’ll Thrive Here If

• You bring a generalist, entrepreneurial, startup-friendly mindset

• You enjoy operating with ambiguity and ramping up quickly on unfamiliar parts of the stack

• You’re comfortable stitching together services and systems you haven’t worked with before

Minimum Qualifications

• 4+ years of experience in software development

• Demonstrated track record of shipping production systems

• Strong systems thinking and logical reasoning

• High ownership mindset; operates well with minimal supervision

• Comfortable with ambiguity and fast iteration cycles

• Experience with APIs, automation tools, or AI platforms

• Ability to reason about infrastructure tradeoffs and system reliability

Preferred Qualifications

• Experience with data pipelines, analytics, or telemetry

• Strong UX and front-end sensibility

• Portfolio or GitHub showcasing deployed systems

• Stack: React / Vue / Angular · Node.js / Python / Java

What Success Looks Like:

• Consistently reduces cycle time from idea to production

• Ships production-grade systems, not experiments

• Balances quality, latency, and cost in system design

• Builds evaluation loops that improve product performance over time

Why You’ll Love Working Here:

• Massive Impact: Your work directly affects millions of businesses worldwide

• High Autonomy: We trust builders to own outcomes, not just tasks

• Remote-First: Work from anywhere; we measure results, not hours

• AI-Native Stack: Latest tooling to accelerate building and experimentation

• Builder Culture: We value speed, ownership, clarity of thought, and execution
