> As a Senior Infrastructure Engineer, you will own and evolve the foundational systems powering Casca's AI-driven lending platform.

## Job Description

## Role Overview
We're looking for a Senior Infrastructure Engineer to own and evolve the foundational systems that power Casca's AI-driven lending platform. You'll build and maintain the infrastructure that enables our engineering team to ship quickly and reliably—CI/CD pipelines, cloud infrastructure, deployment automation, and observability systems. You thrive on making other engineers more productive while ensuring our platform remains secure, compliant, and highly available.

This is a hands-on role. You'll write significant code, debug complex distributed systems issues, and drive technical decisions that impact the entire engineering organization.

## What You'll Do
* Design, build, and maintain CI/CD pipelines and deployment automation that enable fast, safe releases across multiple environments.
* Own infrastructure-as-code (AWS CDK, Terraform or Pulumi) for cloud resources across AWS and Cloudflare
* Build and improve observability systems—metrics, logging, tracing, and alerting—that give engineers deep visibility into system behavior and enable rapid incident response.
* Develop internal tooling and automation that eliminates toil and accelerates developer workflows.
* Drive reliability improvements: capacity planning, failure mode analysis, disaster recovery, and incident response processes.
* Collaborate with product engineers to design systems that are operationally sound from day one—balancing speed of delivery with long-term maintainability.
* Contribute to security and compliance initiatives, ensuring infrastructure meets the requirements of a regulated fintech environment.

## What You'll Bring
* 5+ years of experience in infrastructure, platform engineering, or SRE roles, with a track record of building systems that other engineers depend on daily.
* Strong coding skills in at least one of: Python, Go, TypeScript, or Rust. You write production-quality automation, not just glue scripts.
* Deep experience with cloud platforms (AWS preferred) and their core services—compute, networking, IAM, managed databases, and storage.
* Proficiency with infrastructure-as-code tools (Terraform, CDK, Pulumi) and CI/CD systems (GitHub Actions, BuildKite, or similar).
* Solid understanding of containerization (Docker) and container orchestration concepts, with hands-on experience running production workloads.
* Experience building and operating observability stacks—you've instrumented systems, built dashboards, and used telemetry data to diagnose production issues.
* Familiarity with common failure modes in distributed systems and strategies to mitigate them (blast radius control, graceful degradation, rollback mechanisms).
* Comfortable working in a fast-paced environment where you'll need to balance "doing it right" with "shipping it now."

## Nice to Have
* Experience in regulated industries (fintech, healthcare) where security and compliance are first-class concerns.
* Familiarity with ML pipeline orchestration.
* Experience with multi-tenant SaaS architectures and customer-specific deployment requirements.
* Contributions to on-call rotations and incident response in high-stakes production environments.

## What you'll get:
* **Impact & Ownership:** A unique opportunity to shape the future of banking through AI, owning end-to-end product initiatives.
* **Collaborative Environment:** Work alongside a talented and passionate team that values continuous improvement and knowledge sharing.
* **Competitive Compensation:** Includes salary, benefits, and potential equity in a fast-growing startup.
* **Professional Growth:** Access to resources and mentorship to expand your skill set, influence strategy, and accelerate your career.
* **Culture of Innovation:** We encourage risk-taking, learning from failures, and pushing the boundaries of what’s possible in fintech.
