Principal Platform Engineer

Location: San Francisco, CA or New York, NY

Hiring Manager: VP Engineering

We’re building a software platform for company builders. Our mission is to enable the next generation of bold, visionary companies to thrive. Each tool is something we choose to invest in to create eco-system reform, a fundamental part of our mission.

Our engineering team is small and you will be a key member, fully participating in the design and evolution of our tooling and practices. Our engineers believe in writing tests, refactoring mercilessly, and that the best code is the code you never have to write. We are a fast-moving startup, but we also prioritize sustainable development, taking advantage of the efficiencies of a small team to have a disproportionate impact.

As a principal platform engineer you will have an opportunity to create the software architecture and services powering LTSE Tools working with other engineers as your customers. These services are key to providing interoperable tools to our end users and in helping us to quickly and iteratively build new feature sets. They provide a common layer for data access and sharing, account provisioning and entitlements, usage metrics and reporting. You will work closely with your engineering colleagues as well as partners and customers to support our mission of providing software for company builders.

LTSE is committed to building the inclusion of women and underrepresented developers in from the start.
