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
