This role is part of ourKeyword.comteam, one of our growing brands atsaas.group.
AtKeyword.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 ofsaas.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 expandKeyword.combeyond 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, API integrations (OpenAI, Anthropic, etc.), structured output parsing, and evaluation of LLM responses
- Experience designing and building data pipelines and working with large-scale data processing
- A product mindset: you think about user problems first, not just technical implementation. You form opinions on what to build and why
- Comfort with ambiguity — you can take a vague problem, break it down, prototype fast, and iterate based on feedback
- Strong communication skills — you can explain technical decisions in terms of user and business impact
- Senior-level ownership: you plan meticulously, ship reliably, and proactively identify risks and opportunities
Nice-to-have
- Experience with modern frontend frameworks (React, Vue.js, or similar)
- Experience with web scraping or browser automation
- Familiarity with OLAP databases like ClickHouse for analytical workloads
- Background in SEO tools, rank tracking, or search ecosystems
- Experience with AI agent frameworks or building autonomous LLM-powered systems
- History of side projects, open-source contributions, or founding your own product
