Job description

About the company Our client is an AI-native mortgage technology company rebuilding loan origination from the ground up. Its platform already supports more than $85B in home loans, and a top-10 U.S. mortgage lender is on track to go live by the end of 2026. The company has raised $44M, including a recently closed $30M Series B, has approximately 80 employees, and is positioned to become profitable as its flagship customer launches. The role and why it matters This is a senior or staff-level platform engineering role for a hands-on software engineer who can treat infrastructure as a product. You will build the self-service systems, TypeScript libraries, deployment automation, and reliability foundations that let product engineers ship quickly and safely as the company scales. What you'll do • Own and evolve AWS infrastructure using Terraform and Pulumi across compute, networking, storage, security, and data services. • Design and maintain internal developer tooling, TypeScript libraries, shared SDKs, code generation, command-line tools, and reusable frameworks. • Build and optimize CI/CD pipelines in Buildkite and maintain per-pull-request ephemeral environments. • Improve reliability through service-level objectives, error budgets, autoscaling, observability, and incident response. • Solve performance and scale challenges across Aurora PostgreSQL, distributed services, and an AI-native mortgage platform. • Partner with product engineers to make development, testing, and deployment fast, consistent, and safe. • Document complex systems clearly and raise the technical standard across the engineering organization. What we're looking for • Seven or more years of software engineering experience, including substantial platform, infrastructure, or backend work. • Strong experience at a high-growth technology startup. • Recent hands-on experience building and maintaining CI/CD pipelines and per-pull-request environments, ideally with Buildkite. • Proficiency with TypeScript and Node.js, including the ability to navigate and make meaningful changes to a production codebase. • Deep AWS experience across compute, networking, storage, security, and data services. • Strong Terraform and/or Pulumi skills, including modules, workspaces, and CI-driven plan and apply workflows. • Experience with service-level objectives, error budgets, incident response, and production observability. • A track record of shipping production code, not solely administering infrastructure or coordinating other engineers. • Strong written communication and the ability to document complex systems. Bonus points • Hands-on Buildkite optimization experience. • Experience building internal platforms, developer tooling, shared SDKs, code generation, or frameworks. • Experience with Datadog, CloudWatch, Sentry, distributed tracing, or comparable observability systems. Compensation and benefits • $150K-$350K base salary, depending on seniority and experience. Senior-level compensation may reach $300K base, while staff-level compensation may reach $350K base. • Competitive equity. • Medical premiums covered at 100% for employees and their families, plus dental and vision coverage. • 401(k), HSA and FSA options, and flexible time off. • This role is not open to visa sponsorship or transfers. Candidates must already have unrestricted U.S. work authorization. Location and work model This is a full-time, remote role based in the United States. The company operates as a remote-first team.
