Job description:

We’re looking for a **Founding Engineer** to help build the core systems that power Questom. This is not a framework-specialist role. It’s not about perfect abstractions on day one. It _is_ about systems thinking, ownership, and the ability to stitch together complex infrastructure into something that works — fast. You’ll be one of a very small group shaping not just the product, but _how_ the company builds. ## **What You’ll Do** ### **Build systems that connect everything** * Design and build high-performance systems that connect: * Communication platforms (voice, SMS, email, chat) * Agentic workflows * External tools like CRMs and internal APIs * Stitch together APIs, workflows, and agents into cohesive systems that actually run in production * Think deeply about how these systems scale across many customers with different data sources and configurations ### **Build agentic workflows** * Create workflows where agents: * Handle live conversations * Pull context from systems like Salesforce * Log outcomes in tools like HubSpot * Take real actions on behalf of users * Focus on _giving agents the right information at the right time_ and designing systems that make this repeatable across customers ### **Turn ambiguity into working software** * Start from half-baked ideas, rough customer conversations, or incomplete requirements * Ship a 90% working solution quickly * Iterate toward something more general, scalable, and high quality ### **Own what you build** * Take end-to-end ownership: design → build → ship → improve * Break things thoughtfully — and fix them yourself * Make judgment calls without needing constant guidance ## **What Success Looks Like** **In the first 30 days** * Sit in a few customer conversations * Identify a real pain point * Propose a product or feature to solve it * Build and ship an end-to-end solution that delivers real value **In the first 90 days** * Take learnings from multiple customer builds * Start shaping more general-purpose systems * Help lay the foundation for a platform that can scale to many customers — and eventually very large companies ## **How We Build** * We use modern tools aggressively and expect you to learn quickly: * Agentic workflow frameworks * Communication infrastructure * AI agent SDKs * We rely heavily on coding agents and automation — curiosity and systems understanding matter more than syntax mastery * We build fast, then make it better * We’re opinionated, iterative, and comfortable changing direction when a simpler solution delivers customer value ## **What Matters (and What Doesn’t)** ### **What matters a lot** * **Systems thinking** * **Ownership** * **Comfort with ambiguity** * **Curiosity and fast learning** * **Product taste** (what’s worth building vs not) * **Respect for how other people think** ### **What doesn’t matter much** * Deep expertise in any single framework or language * Pixel-perfect UI work * Writing perfect SQL by hand * Knowing our exact stack on day one If you understand how modern web systems, APIs, workflows, and agents fit together — and you’re excited to learn the rest — you’re in great shape. ## **How We Work** * Fast, opinionated, iterative * Disagreements are encouraged and happen openly * We build first, think later — but we _do_ think * You won’t be micromanaged * You will be trusted with real responsibility early ## **Who You Are** You likely describe yourself as: * Extremely curious * Highly independent * Comfortable operating without a map * Someone who enjoys connecting dots across systems * High-EQ and collaborative You want to be deeply involved — not just shipping tickets, but helping build a company. ## **Who Should Not Apply** * If you need clear specs and guardrails to do your best work * If you prefer working in isolation * If you’re uncomfortable with constant ambiguity * If you don’t enjoy discussing ideas, systems, and tradeoffs with a small team * If you want a narrow role instead of broad ownership If reading this makes you feel _slightly intimidated but very excited_, that’s intentional — and probably a good sign.
