Questom, a Y Combinator-backed startup, is seeking a Founding Engineer to develop its core systems. This role is pivotal for shaping both the product and the company's engineering culture. The position requires a blend of systems thinking, ownership, and the ability to connect complex infrastructures. Candidates should be comfortable with ambiguity and have a strong curiosity for learning new tools, particularly in the realm of agentic workflows and communication platforms.

The ideal candidate will design and build systems that integrate communication tools like voice, SMS, email, and chat with agentic workflows and external systems such as CRMs. This involves stitching together APIs, workflows, and agents into cohesive, production-ready systems. Questom emphasizes the importance of scaling these systems across multiple customers with diverse data sources and configurations. The company uses modern tools and expects engineers to quickly adapt to frameworks like React, TypeScript, and PostgreSQL.

Questom aims to revolutionize B2B sales by merging AI communication with state-of-the-art workflow orchestration. Their agents not only communicate with customers across various channels but also perform tasks within the same tools used by their teams. This approach is designed to build high-quality relationships and deliver value, eliminating the need for manual coordination. With a focus on fast iteration and production deployment, Questom is building systems that can scale to support large enterprises.

As a YC F25 company, Questom is part of a prestigious cohort of startups. The role offers a competitive salary of $125K - $150K along with equity options ranging from 0.75% to 1.50%. Potential candidates should be prepared for a fast-paced, iterative environment where they will be trusted with significant responsibilities early on. This opportunity is ideal for those who thrive in dynamic settings and are eager to shape the future of AI in sales.
