Negotiable
I’m looking for a senior, hands-on AI engineer to help build the core intelligence layer of a new B2B SaaS platform. This is a founding role for someone who wants to design and build real AI systems — not demos, not chatbots bolted onto workflows, and not endless CRUD features. If you enjoy solving hard problems around prediction, learning from behavior, and turning messy real-world data into reliable outcomes, keep reading. What you’ll be building You’ll architect and implement AI-driven systems that: • Ingest and reason over structured and unstructured business data • Generate forward-looking predictions and probabilistic forecasts • Learn and improve accuracy over time based on: • Historical outcomes • Individual user behavior • Feedback loops and variance analysis • Interact with users via intelligent, conversational workflows • Ask targeted questions and incorporate responses into real-time predictions • Integrate large language models into production systems (prompting, orchestration, evaluation, guardrails) • Connect with enterprise platforms such as Salesforce and HubSpot • Scale reliably and transparently so users trust the outputs You’ll be making core architectural decisions — this is not an “implement someone else’s design” role. What I’m looking for Must have • 5–10+ years of professional software engineering experience • Strong Python background (or equivalent) for AI/data-heavy systems • Hands-on experience with: • Machine learning models (forecasting, probabilistic, or time-series a plus) • LLM integration (OpenAI, Anthropic, etc.) • Data pipelines and feature extraction • Experience building systems that learn from user behavior over time • Comfortable working in ambiguity and shaping solutions from first principles Nice to have • Experience with prediction, recommendation, or forecasting systems • Familiarity with CRM data models (Salesforce, HubSpot, RevOps tooling) • Experience designing AI agents or multi-step reasoning workflows • Startup or early-stage company background • Exposure to B2B SaaS, revenue operations, or sales analytics How you work • You think in systems, not just features • You care about accuracy, explainability, and trust • You’re opinionated, pragmatic, and comfortable owning outcomes • You like building things that actually get used Why this role • Founding-level impact • Real AI problems, not hype projects • Direct collaboration with a founder who brings deep domain expertise and customer access • Meaningful Equity 📩 Interested? Send a short note on: • Why this role caught your attention • Relevant systems you’ve built (GitHub, products, case studies, or write-ups) If you’re a builder who wants to apply AI to real decision-making — not slide decks — I’d love to talk.
