Founding Engineer

• 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.
