Senior Software Engineer

Our vision

We’re a small, ambitious team on a mission to redefine personal finance.

Imagine an AI assistant that helps you make big (and small) money decisions with confidence. We’re combining cutting-edge tech with a user experience that feels simple, inspiring, and human - everything a financial advisor should be. That’s our vision.

We’re talking about something that hasn’t been done before – so if you’re into bold, ambitious projects that could change lives, read on.

What you’ll do

As a Senior Software Engineer, you’ll be at the core of making this vision a reality. You'll build and own backend systems. We already have dozens of agents and external services talk to each other to answer complex financial analysis questions. We’re looking to simplify where possible, and continue adding intelligence. Expect to work primarily in Python with some TypeScript/Node.

You’ll interact with cutting edge models, including LLMs, embedding models, and cross-encoder models to deliver smart, nuanced answers. We use a combination of open-source self-hosted models and API endpoints.

Our tech stack

• Backend: Python & Typescript
• Frontend: React & React Native
• Infra: Mainly Kubernetes on GCP, with a bit of AWS and Azure. We love Terraform!
• Databases: MongoDB and Postgres

Who you are

We’re looking for someone exceptional. Someone who loves to create, own, and push boundaries. Your abilities and passion are what matter most to us, not the degrees or years of experience. Here’s what we’re hoping to find:

• You love coding: Like really love coding. It’s a hobby as much as a job.
• You write beautiful code: We care about code quality and doing it right the first time. If you’re a fan of clean, maintainable code, you’ll fit right in.
• Take ownership: You’re not just here to code; you’re here to create something lasting, taking complete ownership over what you build. You know how to take a project from zero to one.
• Strong opinions, loosely held: Confident in your expertise and opinions but willing to adapt to new information.
• Good vibes only: We’re building something awesome and want to enjoy the process together. Low ego, high energy and kindness is what we’re about. No BS, we’re here to build and have fun.

What’s in it for you

• In office work: We believe collaboration is much more effective in office, and way more fun!
• Competitive salary & equity: Starting at $120k–$200k with 0.1%–0.5% equity plus health insurance.
• Be part of something big: This is a rare chance to help shape the future of a product that could redefine how people manage money.
• Freedom & trust: You’ll have the freedom to run your projects and show us the best way forward.

The day-to-day

Our office isn’t just a place to work—it’s a place to connect, create, and have fun. Whether it’s team lunches, Super Smash Bros. tournaments, or hitting the gym together, coming into work feels like hanging out with friends. Our culture is like one big family: we genuinely support each other, building friendships that extend beyond work. From sharing snacks in our fully stocked kitchen to trying out new activities like rock climbing, we’re all about creating a close-knit, supportive team that makes every day enjoyable.
