Senior Fullstack Engineer

CoLoop is revolutionizing the insights and strategy space with their AI-first customer intelligence platform. As a Senior Fullstack Engineer, you'll join a team of 9 based in central London that's experiencing rapid growth with 400% ARR growth in the last 12 months. The company has raised $5M and is already profitable, serving 250+ large agencies & research teams including Amazon, Financial Times, P&G, and Publicis Sapient.

The role offers a unique opportunity to work on cutting-edge AI applications in a highly autonomous environment. You'll be part of a small, cross-functional team of experienced operators, working directly on a product that reduces marketing research time and costs by 70%. The tech stack is modern and well-thought-out, including React with TypeScript, NextJS, Python for AI services, and AWS infrastructure.

What makes this role special is the combination of technical challenges and direct business impact. You'll work on everything from AI implementations to complex system architecture, while having real influence on product direction. The company culture emphasizes hard work, evidence-driven decision making, and continuous learning.

CoLoop is solving a significant market problem - enterprises waste billions on bad decisions due to slow, expensive, and fragmented research processes. As part of the team, you'll help build solutions that make strategic insights fast, comprehensive, and effortlessly accessible. The company's vision is to make every company as customer-obsessed as Amazon by giving the next generation of workers immediate, intuitive access to the knowledge they need.

The interview process is streamlined and practical, including real engineering tasks and team interaction, typically completed within 1-2 weeks. While the requirements are specific, CoLoop encourages applications from diverse candidates who might not meet every qualification but bring valuable perspectives and skills.
