Technical Lead

About Fairground

Fairground is a B2B GTM data platform. We ingest, enrich, and structure millions of company and contact records across verticals, and turn them into reliable go-to-market signal inside our products. Data is the product - and how well we build the pipeline behind it is the business.

What You’ll Do

Design, implement, and optimize scalable backend systems and AI-driven workflows from spec to production.

• Own the architectural roadmap - making pragmatic, high-leverage decisions that scale with the platform.
• Lead integration of LLM models, agentic frameworks, and workflow automation to enhance sales intelligence features.
• Profile, debug, and optimize the platform for high availability, low latency, and seamless third-party integrations.
• Take high-impact features from discovery through deployment - writing technical designs, breaking down complexity, and iterating on feedback.
• Write clean, maintainable, well-tested code. Champion engineering best practices and lead code reviews.

What We’re Looking For

• 7+ years of software engineering experience, with a meaningful portion in senior or lead roles at fast-paced startups.

• Strong proficiency in Python, Node.js, or similar; proven ability to architect complex systems and navigate large codebases.
• Solid working knowledge of PostgreSQL, MongoDB, or comparable - schema design, query optimization, indexing.
• Hands-on experience on AWS, GCP, or Azure (containerization, CI/CD, observability).
• Experience with AI/LLM agentic frameworks (LangChain, CrewAI, AutoGen) or low-code / workflow automation platforms.
