Senior Software Engineer (Full-Stack - Backend Heavy)
Predactiv, Palo Alto, California, United States, 94306
About Us:
Predactiv is a high-scale, high-impact data platform company. We process terabytes of data and billions of events every single day - powering AI-driven insights, audience segmentation, and real-time decisioning for AdTech, MarTech, and beyond.
We're a lean, elite engineering team that moves fast, ships often, and solves hard problems with elegance and speed. We don't have layers of bureaucracy - if you build it, you ship it, and you own it. Our stack blends Node.js, Python, GoLang, React, TypeScript, Tailwind, MongoDB, Elasticsearch, DynamoDB, and AWS to deliver performance at scale.
Responsibilities: * Backend (70%) - Architect, build, and optimize high-performance APIs and backend services in Node.js (primary), with contributions in Python and GoLang. * Work with MongoDB, Elasticsearch, and DynamoDB to design and tune data flows for speed and scalability. * Tackle large-scale distributed system challenges - billions of events, massive datasets, and sub-second response times. * Frontend (30%) - Build responsive, modern UIs using React, TypeScript, Tailwind, HTML/CSS to bring features to life. * Collaborate across product, data, and design to deliver full-stack features from idea to deployment. * Profile, debug, and optimize performance across the stack - no silos, no hand-offs. * Contribute to architecture, code reviews, and technical decision-making.
Requirements: * 5+ years of professional software engineering experience, with a proven track record in backend/API development. * Deep expertise in Node.js (JavaScript/TypeScript) for backend systems. * Strong experience with React, TypeScript, Tailwind, HTML/CSS for frontend work. * Hands-on experience with at least one NoSQL database (MongoDB, Elasticsearch, or DynamoDB). * Sharp problem-solving skills and the ability to figure things out fast. * Familiarity with Python or GoLang (bonus if both). * Comfortable working in a lean, fast-moving, Agile environment. * Bonus: AWS experience and background in large-scale distributed systems.
