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 seeking a Senior Software Engineer to spearhead our Core Platform function. In this high-leverage role, you'll design and scale the foundational systems that power our AI-driven lending platform. You'll build scalable, secure, and reliable infrastructure that handles sensitive financial data, integrates AI models for loan processing, and supports high-availability deployments across cloud environments. You thrive on cross-functional collaboration with engineering, product, and compliance teams to deliver velocity, reliability, and compliance in a competitive fintech landscape.

What you'll do:

• Architect and enhance platform features including authentication, auditability, and enterprise integrations across the banking ecosystem.

• Build and maintain high-performance, developer-friendly infrastructure using containerization (Docker), orchestration (Kubernetes, Helm), and cloud-native services across AWS, Azure, and GCP.

• Improve reliability, scalability, and compliance for platform services like permissions management, admin reporting, and customizations

• Develop and optimize infrastructure as code (AWS CDK, Terraform) and CI/CD pipelines to automate deployments, ensuring high availability, disaster recovery, and efficient resource utilization.

• Collaborate with AI engineers to benchmark & integrate models into the core platform.

• Mentor junior engineers, conduct code reviews, and contribute to best practices for building systems that handle high-volume, mission-critical financial workflows.

• Create and maintain comprehensive documentation for architecture, runbooks, and operational procedures.

• Stay ahead of emerging technologies in cloud-native, fintech, and AI infrastructure to drive innovation in our platform.

What you'll bring:

• Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent experience)

• 5+ years of software development experience, particularly in scalable backend and infrastructure systems (e.g., Rust, Node.js, Python, or Go), and modern deployment technologies like Docker, Kubernetes, and Helm.

• Strong experience with major cloud platforms (AWS, Azure, GCP) and their managed services for compute, storage, and networking.

• Proficiency in infrastructure as code tools (e.g., AWS CDK, Terraform, Pulumi) and CI/CD automation (e.g., GitHub Actions, Jenkins).

• Experience with building observability tooling including metrics collection, distributed tracing, logging systems, and monitoring dashboards.

• Experience with enterprise software features like permissions (RBAC), analytics, audit logs, notifications, self-serve onboarding, and provisioning.

• Proven ability to mentor and guide technical teams.

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.

As an early-stage company building at the frontier of AI, we work with high intensity and commitment. While schedules can vary by role/team, many weeks will demand extra focus, flexibility and time particularly during major launches and high impact sprints. We're seeking those who are aligned to and able to commit to that expectation which includes 5 days per week in our San Francisco Office.
