Descripción de la vacante

ISpeedToLead Inc. seeks a Senior AI Product Engineer to build the AI operating layer behind our marketplace. You will own end-to-end production systems—from problem framing to deployment—delivering measurable business impact with reusable components.

You will ship LLM-powered features, automate workflows, and ensure quality, security, and performance in a fast-moving, AI-first environment. Remote-friendly with strong collaboration.

Formación

• Production-grade software: end-to-end shipping in SaaS/marketplace context.
• Strong Python and/or TypeScript; APIs, databases, auth, testing, deployment.
• Experience shipping LLM-powered features with model APIs, tool calling, retrieval, context engineering, and agent workflows.
• Automation: webhooks, events, queues, retries, idempotency, monitoring, failure recovery.
• Evaluation: test sets, traces, metrics, regressions, feedback loops.
• Daily AI coding agent usage; review, test, refactor, secure outputs.
• English proficiency: C1+ with US-based stakeholders.

Responsabilidades

• Discover high-value product and operational problems by working directly with users, business owners, and internal teams, then frame clear success criteria before writing code.
• Design and ship customer-facing AI features and internal automations across lead quality, matching, prediction, call intelligence, CRM, support, and operations.
• Build agents and workflows that safely use tools, APIs, databases, calls, SMS, email, and other company systems — with human approval where risk requires it.
• Create the context layer around models: instructions, retrieval, memory, structured outputs, tool definitions, permissions, and feedback loops.
• Build reliable event-driven and scheduled automation using webhooks, queues, schedulers, retries, idempotency, audit logs, and graceful fallbacks.
• Create evaluation datasets and automated checks that measure usefulness, accuracy, failure modes, regressions, latency, and cost — before and after release.
• Investigate real production failures and improve the complete system, not just the prompt or the model response.
• Turn successful solutions into reusable components and patterns that support additional iSpeedToLead niches without rebuilding from zero.
• Own architecture, quality, security, and business outcomes — not just the pull request.
