Senior Infrastructure Engineer

Senior Infrastructure Engineer WHY CASCA? Casca is building AGI for banking. We’re replacing decades-old legacy systems with AI-native technology that automates 90% of the manual work humans once had to do. 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 boundarie ...
