About Pennant

Pennant is a YC-backed company building software for corporate governance, starting with proxy voting and company engagement.

Institutional investors, public companies and their advisors make consequential decisions using information scattered across filings, policies, research and conversations. We bring that information together so teams can understand the evidence, apply their own judgment and preserve why they made a decision.

Our ambition is a world model for corporate governance: a system that connects institutional knowledge, policies, decisions and outcomes. Getting there starts with reliable data and software customers trust in their daily work.

The role

Own a customer workflow from understanding the problem through repeated production use.

This is a full-stack engineering role with product judgment and customer ownership. You will build on an existing application, connecting interfaces, backend APIs, persistent state and integrations into complete workflows. You should be comfortable tracing a user action from the browser to the database, and owning what happens when only part of that sequence succeeds. You will work directly with customers to observe how they work, challenge assumptions, prototype interactions and follow up after release.

Your likely first assignment is a focused research or company-engagement workflow: help an analyst review evidence, make a decision and follow through. The goal is a useful, reliable sequence, not a collection of disconnected screens or an entire CRM built before a customer can use it.
