If we jointly decide to move forward, you can plan to (virtually) attend a 45-minute video interview with a member of our Product Team. Next there will be a deeper technical conversation with our Founder and Chief Product Officer. The final stage would be to meet (2-4) other members of the team via video conference for additional conversations about your approach to collaboration, your relevant experience to current projects, and alignment with our values. All in, you can expect the time commitment for this stage to be 3-4 hours of synchronous interaction, scheduled to fit your needs.

The Mission

We're building the first truly intelligent insurance brokerage, transforming a $100B+ Excess & Surplus(E&S) insurance market that runs on pre-internet systems. We are looking for exceptional engineers who can architect and deploy AI systems that make complex decisions at unprecedented speed. This isn't about adding chatbots to insurance - it's about building AI systems that can handle intricate, multi-step workflows autonomously, turning weeks of manual work into automated, instant processes.

You're Our Person If

* You ship features daily and think in weekly roadmaps, not months

Hard Requirements

* Must be in San Francisco during YC W25 batch (Jan-March 2025)

Indicative Timeline Targets

Our pace is ambitious because we know what's possible. Here's what your impact could look like:

First Few Days: Master our data flows while simultaneously shipping your first feature - an AI form generation system with RAG capabilities. You'll be integrating Elasticsearch for intelligent document retrieval, proving we can move at unprecedented speed.

First Week: Transform how we handle customer interactions by deploying real-time voice AI that works alongside our human operators. This isn't just about transcription - it's about building AI that can understand complex insurance conversations and make intelligent decisions in real-time.

Second Week: Build intelligence into our market communications. Create systems that prioritize and route submissions to carriers, monitor for objections, and manage complex data flows - turning what typically takes weeks into an automated, instant process.

Third & Fourth Weeks: Take our AI systems to the next level - from handling complex voice conversations to deploying autonomous agents for payment processing and portal interactions. You'll build systems that can navigate the maze of insurance websites, extract critical information, and feed it back into our workflows.

Your Domain & Impact

You'll be building our core AI infrastructure:

* Decision Systems: Design AI that can handle complex insurance decisions

Evolving Tech Stack

Building for velocity today, engineering for scale tomorrow:

Data & Pipelines:

* Unstructured, Airbyte

AI/ML Infrastructure:

* Embedding Models: OpenAI, HuggingFace

Orchestration & Operations:

* Retool workflows, Temporal workflows

LLM Stack:

* APIs: Claude, OpenAI, Groq

Platform & Frontend:

* Cloud: GCP

How We Execute

1. Make Requirements Less Dumb: Question everything. If someone says \"that's how insurance works,\" that's exactly where we start

Our SDLC

* Boundaries of Separation: Build core IP, leverage existing tools for speed

Our Philosophy

\"Move fast. Break things. Fix them faster.\"

\"Strong opinions, loosely held\"

Join as an Owner, Not an Employee

Base compensation for this role ranges from $100-180K depending on your experience:

* Early Career (1-2 years): $100-125K

But let's be clear - if you're just comparing base salaries, you're missing the point.

We're building something that could transform a $100B+ industry, and we want our early team members to have meaningful ownership in that journey. That's why we offer significant equity packages that make you a true owner, not just an employee. We're looking for people who understand that the real upside comes from building and owning something revolutionary, not from maximizing their base salary.

Think like an owner because you will be one. If you're primarily optimizing for cash compensation, we're probably not the right fit. If you're excited about building something massive and owning a meaningful piece of it, let's talk.

We also use these images in our local development environment allowing coding locally against all of our services. We have a well-documented public API that is consumed by our front-end JavaScript app as well as numerous integrations. Our infrastructure is heavily automated using Terraform, Ansible and other AWS tools.

Our product development process is inspired by Shape Up. We love open sourcing our code and ideas on our GitHub and on The Making of Close, our behind-the-scenes Product & Engineering blog. Check out our open source projects like SocketShark, TaskTiger, LimitLion and ciso8601.
