Ready to take on the challenge?
DX and Performance Team The team’s primary goal is to increase Factorial’s quality, performance, and scalability by continuously improving the way we build our product. We focus on strengthening our tools, maintaining foundational elements, and promoting best practices in close collaboration with the rest of the engineering organization.
Our mission is to equip product builders and business teams with robust, AI-enabled tools and practices to deliver and interpret insights with quality, confidence, and efficiency. We work across teams to improve analytical software patterns, optimize high-scale data queries, and raise the overall data and engineering bar across the company.
Within this context, real-time analytics and intelligent data access are an increasingly important area of focus. As Factorial continues to scale, we want to strengthen how we handle massive-scale data ingestion, build highly efficient OLAP structures, and apply modern LLM workflows to bridge the gap between complex databases and natural language querying.
As an Engineer at Factorial, you’ll be part of a team of 200+ Engineers. We look for people who are curious, proactive, technically strong, and effective communicators. People who enjoy solving complex technical problems, raising standards across teams, and building systems that help the whole organization perform at a higher level.
In this role, you will help shape how Factorial processes, models, and queries high-performance analytical data. You will work closely with product and data teams to design semantic models from scratch, optimize complex columnar data stores, and build modern text-to-SQL or conversational BI capabilities that govern how users interact with data.
You will partner with engineering leaders across product and infrastructure to build robust data pipelines and ensure our AI integrations are grounded, accurate, and secure against hallucinations.
This is a cross-cutting role with broad impact. You will contribute through hands-on technical work, technical leadership, and by helping teams adopt stronger practices around real-time streaming ingestion, semantic layers, and AI-driven analytics.
You’ll work in a multicultural, English-speaking environment where your technical depth, systems thinking, and problem-solving skills will directly contribute to our mission of improving business management processes for companies worldwide.
Factorial serves 15,000+ active customers and 1M+ active users across business-critical workflows. Our current environment includes:
Don’t let unfamiliarity with every part of this stack hold you back. If you have worked in complex data systems, know how to reason about performance at scale, and are excited to help teams build next-generation AI-driven analytics, we want to talk to you.
