Y Combinator-backed Questom is hiring a founding engineer to develop its AI agent platform that automates sales workflows across communication channels and business systems.
Questom, an emerging startup in the Y Combinator F25 batch, is recruiting a founding engineer to help build its AI agent platform for B2B sales teams. The San Francisco-based company (offering remote work for US/India candidates) aims to automate sales workflows by connecting communication channels with business systems through AI agents.
The role focuses on developing systems where AI agents handle conversations across voice, SMS, email, and chat while integrating with tools like Salesforce and HubSpot. Unlike typical engineering positions, this role prioritizes systems thinking over framework specialization. Candidates will design infrastructure that enables agents to pull context from CRMs, log outcomes, and take actions on behalf of users.
Key technical challenges include:
- Creating workflow orchestration for real-time conversations
- Building scalable integrations across diverse customer data sources
- Designing context-delivery systems that provide agents with relevant information
- Developing fault-tolerant pipelines for production environments
The company uses React, TypeScript, PostgreSQL, and Next.js in its stack, but emphasizes that understanding how "modern web systems, APIs, workflows, and agents fit together" matters more than specific syntax mastery. Their development philosophy prioritizes shipping "90% solutions" quickly then iterating toward scalability.
Success metrics for the role include shipping a customer-facing feature within 30 days and developing generalized workflow systems within 90 days. The position offers $125K-$150K salary plus 0.75%-1.50% equity, targeting engineers comfortable with ambiguity who prefer broad ownership over narrow specialization.
Questom's platform targets sales teams burdened by manual follow-ups and data coordination. By automating these processes, the startup aims to shift sales efforts toward high-value relationship building. With two founders and paying customers already onboard, the company is building toward systems capable of supporting enterprise-scale deployments.
