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.
