Role Overview We are hiring a Team of One – Full Stack Builder. This is not a traditional engineer role. This is not a traditional product manager role. You will own a problem space end-to-end — from discovery and strategy to architecture, implementation, launch, metrics, and iteration. You are responsible for outcomes, not tasks. You will think like a Product Manager, execute like a Senior Engineer, and own impact like a Founder. What You’ll Do 1. Product Discovery & Problem Framing Own a clearly defined problem area within the platform. Conduct lightweight discovery: customer calls, support ticket mining, analytics review, win/loss insights, session replays. Write sharp problem statements and define measurable success criteria. Turn ambiguity into structured thinking and validated hypotheses. Identify opportunities to improve activation, retention, revenue, or operational efficiency.   2. Requirements & Product Documentation Define MVP vs V1 vs V2 iterations and define the requirement Goals & KPIs In-scope / out-of-scope User stories & acceptance criteria Edge cases & risks Maintain clear decision logs and documentation. Prevent scope creep through structured thinking. 3. UX & Experience Ownership Design intuitive user flows and information architecture. Think deeply about onboarding, empty states, failure states, and microcopy. Ensure experiences align with platform conventions. Ship functional, usable interfaces even when design support is limited. Advocate for customer clarity and simplicity. 4. Full Stack Architecture & Engineering Execution Architect scalable systems across frontend, backend, APIs, automation, and AI workflows. Ship production-grade code with high reliability and maintainability. Balance latency, performance, scalability, and cost. Build integrations and automation frameworks. Own migrations, backward compatibility, and system resilience. 5. AI-Native System Design Build LLM-powered features, agents, or workflow automation. Design evaluation loops and guardrails. Optimize inference cost, latency, and reliability. Continuously iterate based on real usage signals. 6. Analytics, Instrumentation & Experimentation Define KPIs for every feature shipped. Instrument events, funnels, and telemetry. Monitor adoption, activation, engagement, and failure metrics. Run lightweight experiments or A/B tests. Use data to drive iteration and continuous improvement. 7. Operational Excellence Improve system observability and monitoring. Automate internal workflows to reduce cycle time. Maintain clean documentation and runbooks. Continuously reduce tech debt and UX debt. What Success Looks Like Reduced cycle time from idea → production. Production-grade systems (not prototypes). Measurable improvement in product KPIs. Lower support tickets and improved customer satisfaction. Clear documentation and scalable architecture. Strong ownership and minimal oversight required. 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 Core Technical Skills Frontend frameworks (React, Vue, Angular, etc.) Backend development (Node.js, Python, Java, etc.) API design and system integration Database architecture & optimization Cloud infrastructure fundamentals Monitoring and observability tools Performance optimization Core Product Management Skills Product discovery & customer research Problem framing & structured thinking Roadmapping & prioritization frameworks KPI definition & data-driven iteration UX thinking & experience design Stakeholder communication & alignment Outcome-based ownership mindset Who This Role Is For Builders who prefer ownership over hierarchy and want to own outcomes end-to-end. Engineers who think like product leaders and make strong product decisions. Product thinkers who can ship real, production-grade systems, not just write specs. Individuals comfortable operating in high-ambiguity environments with minimal process. Builders who actively leverage AI tools, automation, and modern development workflows to accelerate prototyping, coding, testing, and product development. Individuals who use AI-assisted development (LLMs, copilots, automation workflows, code generation tools, etc.) to move faster while maintaining high engineering quality. People excited about moving quickly from idea → prototype → production, using AI and automation to dramatically reduce development cycles. Why Join HighLevel Massive scale and real-world impact. Remote-first flexibility. AI-native innovation environment. High ownership and autonomy. Fast decision-making and minimal bureaucracy. Opportunity to build products used by millions.
