Founding Engineer (AI + Backend)
About the role
About OpenFunnel
OpenFunnel is in the business of connecting buyers and sellers - helping companies discover their potential customers that are in the market for the pain points that their products solve for.
The Bet
We see this shaping up in 2 ways - as it stands currently in the form of humans buying and selling, and in the next few years - agents buying and selling. We are set up for both.
About the Role
We are a team of 3 - in person, in SF. With this lean team, we have ~500K in ARR in the last year, and work with the fastest growing companies like Pylon, Telnyx and WriteSonic amongst others. In this next phase, we are focusing on accelerating our vision of connecting buyers and sellers(humans and agents alike). You will be working on mission critical infrastructure and architecture of our data ingestion, indexing and reasoning layer. We process millions of job postings, websites and people data daily to enable our customers with high quality, timely alerts of buying intent.
What You'll Work On
- Large-Scale Data Infrastructure
You'll build pipelines that process and enrich data across 45M+ companies and 1B+ people profiles - making messy, unstructured B2B data inference-ready, queryable, accurate, and fast. Think: real-time change detection across 1B scale data sources, and pre-computed aggregate insights that power instant answers.
- LLM Systems
You'll design AI systems that go well beyond simple prompting - compound agents that combine web search, structured data, and multi-step reasoning to qualify events, score them, and surface action steps.
- Integrations & Operationalization
You'll build the connective tissue between OpenFunnel and our customers' GTM stacks - bidirectional CRM sync with Salesforce and HubSpot, batch replication pipelines, and signal tagging systems that make our data actionable inside the tools sales teams already use.
You will get access to unlimited tokens to become an elite engineer in this new AI coding world, and an environment that is exciting, fun and extremely challenging at the same time. You will be pushed to your limits, and you will surpass them in the process. If you want to do your life’s work, reach out.

About OpenFunnel
OpenFunnel helps connect great B2B SaaS products to companies who need them.
For all of outbound history, GTM teams have relied on blind outbound automation. With AI in the picture, it has gotten worse, it's turned automation into a slop cannon, destroying helpful and relevant outreach in favor of volume spam.
We believe the exact opposite. AI should narrow the search and sharpen the timing, not flood inboxes.
At OpenFunnel, we are building a Real-time Data Engine for GTM Teams and Agents.
Our goal is to achieve near 100% outbound conversion rate, while the state of the art sits at 4%.
