Senior Product Engineer

Remote, Europe This role is part of our Keyword.com team, one of our growing brands at saas.group. At Keyword.com, we're a small team with a big mission: helping SEO pros track and boost their Google rankings. Our tool cuts through the noise, showing businesses what really matters when it comes to optimizing their digital presence. As part of saas.group, our team is scattered across Europe and looking for innovative minds to join our journey. As we continue to grow, we're seeking a Senior Product Engineer to own and deliver end-to-end solutions that expand Keyword.com beyond traditional Google SERP tracking into the emerging world of LLM-powered search. You won't just write code — you'll identify user problems, prototype solutions, ship features, and iterate based on real usage data. If you're someone who thinks in terms of user outcomes rather than tickets, thrives on autonomy, and is excited about leveraging LLMs to build entirely new product categories, this role is for you.

Profile Overview

Your immediate impact in the first 3-6 months will be:

• Become a core member of our product engineering team, owning features from idea to production
• Design and build LLM-based scrapers that extract ranking data for prompts across major AI platforms (ChatGPT, Perplexity, Gemini, etc.) — bringing the same visibility we provide for Google SERP into the LLM search landscape
• Develop LLM-driven workflows and integrations that automate data collection, analysis, and insight generation
• Ship user-facing features end-to-end, including frontend UI, backend services, and data pipelines
• Analyze usage data and use those insights to shape what you build next

Your responsibilities

• Own product outcomes end-to-end: from identifying user problems and prototyping solutions to shipping, measuring, and iterating
• Architect and build LLM-powered scraping systems that monitor how brands and keywords rank across AI platforms
• Design and implement LLM-driven workflows — prompt engineering, response parsing, structured data extraction, and result evaluation at scale
• Build and maintain the frontend experiences (React.js) that surface LLM ranking insights to users
• Develop scalable backend services and data pipelines to support new product areas
• Analyze usage data and user feedback to prioritize what to build, fix, and improve
• Collaborate closely with the team on product direction — bring opinions, back them with data, and help set priorities
• Write clear documentation for the features you ship

Our Tech Stack

• Node.js (TypeScript), PHP (Laravel), React.js
• MariaDB, ClickHouse, PostgreSQL
• RabbitMQ, Redis, Debezium, Kafka

What You bring to the table

• 5+ years of full-stack development experience, with a strong track record of shipping user-facing products end-to-end
• Proficiency in Node.js (TypeScript) for backend services, knowledge of other backend languages is a plus
• Hands-on experience building with LLMs — prompt engineering, MCPs...
