Our People:

With over 1,500 team members across 15+ countries, we operate in a global, remote-first environment. We are building more than software; we are building a global community rooted in creativity, collaboration, and impact. We take pride in cultivating a culture where innovation thrives, ideas are celebrated, and people come first, no matter where they call home.

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
