Responsibilities
Architect signal-driven prospecting systems: Define how intent signals, firmographics, behavioral data, and CRM context combine into actionable prioritization and recommendations
Hands-on, high-leverage builder: Write production code, lead complex initiatives end-to-end, and take systems from prototype to scale
AI + systems thinking: Shape how ML and GenAI models integrate into deterministic workflows, balancing automation with transparency and user trust
Product-shaping technical leadership: Influence what the product should be, not just how it’s built—partnering closely with Product to define surfaces, workflows, and tradeoffs
Platform and extensibility mindset: Design systems that work across accounts, buying groups, and regions while remaining extensible and evolvable
Cross-team influence: Work horizontally across CRM, data, AI, and GTM teams to align patterns and avoid local optimizations
Raise the technical bar: Mentor senior engineers, guide architectural reviews, and turn incidents and failures into better system design
Qualification
Required
Proven experience building and evolving distributed systems at scale, where data quality, latency, and explainability matter
Strong architectural instincts and comfort working across data pipelines, APIs, and user-facing workflows
Experience applying ML or GenAI in real products, with a healthy skepticism for 'magic' and a bias toward trust and control
Strong architectural instincts with a bias toward simplicity, consistency, and well-defined boundaries
A product mindset: you care deeply about helping sales teams do better work, not just building clever systems
