About The Team

The Platform Engineering team at Basis designs, builds, and operates the infrastructure that powers our AI research and products. We’re a lean team that loves architecting large-scale distributed systems from first principles.

We obsess over clarity: clean abstractions, simple mental models, and crisp interfaces that let our AI and product teams move fast without breaking things.

We’re not building features—we’re building foundations for an AI accountant. That means modeling the world the agent lives in (accounting concepts, workflows, and constraints) and providing scalable, observable, and reliable systems that everything else depends on.

About The Role

As a Tech Lead on the Platform team, you’ll hold the technical vision for a core slice of Basis’s infrastructure—how we deploy, model, and serve the data and systems our AI depends on.

You’ll design elegant architectures, make trade-offs explicit, and teach others how to reason about distributed systems with clarity and rigor. You’ll drive coherence across runtime, data, and schema layers—so our systems scale predictably and remain legible as we grow.

You’ll lead by example through code, design reviews, and decision records—ensuring the platform is not just powerful, but beautiful in its simplicity.

What You’Ll Be Doing:

1. Architect and evolve our infrastructure foundations2. Build and standardize our data platform3. Model the domain as a system4. Lead through clarity and technical excellence

📍 Location: NYC, Flatiron office. In-person team.
