Senior Product Engineer (Node)

About the role

ActiveProspect builds products for consent-based marketing, with its flagship TrustedForm certifying over 1 billion opt-in leads annually and its LeadConduit platform connecting lead sellers and buyers. This Senior Product Engineer (Node) role is forward-deployed: you own customer and business outcomes, not tickets, and work across the full stack (Vue/Nuxt and React/Next.js on the frontend, Node.js and TypeScript services on AWS). Work is split between keeping the current platform fast and reliable and building a new real-time engine for ping/post, call tracking and buyer optimization.

Key responsibilities

• Own outcomes end-to-end: frame the problem, design it, ship it and own the metric, distilling to the cheapest version that works.
• Improve the current product (flows, integrations, reporting) and help build the new real-time engine (field mapping, ping/post, call tracking, buyer optimization).
• Shadow sales and support, talk with lead buyers and sellers, join advisory conversations and let customer reality drive technical decisions.
• Own your domain, including interfaces, reliability, performance and security, and cover on-call for the systems you own.
• Ship responsive, accessible interfaces with a strong UI/UX eye, backed by Node.js and TypeScript services and APIs, and keep the real-time, multi-tenant lead and call processing engine reliable at scale.
• Build AI-assisted workflows, adapt to changing tooling (Cursor, Claude Code), and look for product wins AI unlocks.
• Mentor on judgment and product sense, write decision memos and ADRs, and enable Product and Design to self-serve.

Required profile

• A track record of shipping something end-to-end and owning the outcome, not just the code.
• Product judgment: pushing back on bad specs, proposing cheap experiments, descoping and collaborating with Product.
• Comfort embedding with unfamiliar teams and codebases and leaving them better than you found them.
• Strong UI/UX eye, systems design judgment in ambiguous contexts, and a security mindset for sensitive consumer data and compliance.
• Experience mentoring others and clear written and verbal communication.
• 5-10% travel.

Required skills

• Frontend: React/Next.js and Vue/Nuxt, component lifecycle, state management, rendering optimization, JavaScript/TypeScript and modern CSS.
• Backend: Node.js and TypeScript services, RESTful APIs, low-latency, high-volume asynchronous data handling.
• Cloud and real-time: AWS Lambda, EC2, S3, DynamoDB, API Gateway, SQS, SNS, Kafka or similar.
• Fluency building AI-assisted workflows and reading AI output critically, using tools such as Cursor and Claude Code.
• Lead generation or performance marketing experience (ping/post, lead routing, call tracking, TCPA and consent rules) is a strong plus.
