Senior Infrastructure Engineer

Mudflap serves the $800B trucking industry, the backbone of the U.S. economy. Our market-leading payment products help truckers save thousands of dollars on fuel (their #1 business expense), while providing our fuel stop partners with access to new, hard-to-reach customers. We’re a fast-growing marketplace business looking for a new customer-obsessed teammate to join us on this exciting journey.

As a Senior Infrastructure Engineer, you will design, build, and operate the cloud infrastructure that powers our AWS-hosted SaaS platform. You’ll own the reliability, scalability, security, and efficiency of our environments—enabling rapid, safe delivery of new features while maintaining the high level of trust our customers expect.

You will develop and maintain automated CI/CD pipelines, manage infrastructure-as-code deployments, and ensure consistent, repeatable provisioning across environments. You’ll monitor system performance, tune resources for cost and efficiency, and respond to production incidents with a blameless, problem-solving mindset.

As part of the engineering team you will collaborate closely with engineers, product managers, data scientists, and other cross functional team members to implement best practices around observability, reliability, and compliance requirements. You’ll propose architectural improvements, and drive initiatives that enhance system resilience and developer productivity.

Ultimately, you will serve as both a guardian of platform stability and a force multiplier for the engineering organization—building tools, automation, and processes that allow the company to scale confidently and securely.

We value in-person connection and have offices in both Palo Alto and Austin. While we prefer candidates located in these hubs for occasional meetings and team collaboration, we are open to remote team members who can travel periodically if needed.
