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

• End-to-End Product Ownership:
• Translate business goals into working, deployable systems
• Define architecture, workflows, and implementation plans
• Ship and maintain production-grade systems — not demos or prototypes
• Rapid Prototyping & Iteration:
• Turn ambiguous ideas into working demos within hours or days
• Prototype using code, AI tooling, automation, or low-code systems
• Validate through experiments and real user feedback, then iterate to production quality
• Build AI-Native Systems:
• Design and orchestrate LLM agents, retrieval pipelines, workflow automation, memory layers, APIs, and guardrails. Build for resilience against hallucinations, model variability, and quality degradation over time.
• Design for Scale, Cost & Performance:
• Reason through token consumption, inference cost, latency constraints, infrastructure scalability, and system resilience. The goal: systems that work efficiently at scale.
• 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

Minimum qualifications

• 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 building LLM-based or AI-driven products
• Familiarity with evaluation frameworks, monitoring, or instrumentation
• 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
