Sr Platform Engineer (AWS)

Description

Ledgebrook is an AI-native specialty insurance platform. When a business needs coverage that is custom and complex, its broker comes to us, and our underwriters give them an answer, often in hours rather than weeks.

We built our technology from scratch, with AI in it from the first line of code. The technology helps price the risk; the underwriter uses their judgment to decide. There are always two hands on the wheel.

We are insurance industry insiders, and we eat our own cooking: Ledgebrook writes the policy and shares the risk through our own carrier, Ledgebrook Specialty, rated A- (Excellent) by AM Best. We work exclusively through wholesale brokers.

Our vision: to make the wheels of insurance spin faster.

At Ledgebrook, everything we do is driven by our culture: Care, Strive, Thrive Together. To succeed in modernizing the industry, we must first succeed in changing the way we do business. Talent density is our north star—fewer, better people working together as one. To that end we’ve replaced all individual incentives with generous equity packages—we play as a team, we win as a team. Everyone benefits handsomely from Ledgebrook’s success.

• Optimize Network & Traffic Control: Configure and manage our service mesh architecture using Istio to ensure secure traffic flow, robust encryption, and advanced routing capabilities.
• Manage AWS Infrastructure as Code: Codify and maintain all cloud resources using Terraform, ensuring environment consistency across staging and production.
