Senior Software 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.

What you'll do:

• Projected Division of Responsibilities: Roughly
• 70% contributing high-quality code and
• 30% collaborating with stakeholders and supporting your team.
• Own the Lifecycle: Take deep pride in end-to-end component ownership, from initial technical scoping and architecture to deployment, observability, and long-term maintenance.
• Deliver with Pragmatism: Act as a "master of scope" by understanding the "why" behind features. You will propose technical shortcuts or alternative implementations to deliver core value faster, avoiding "complexity for complexity's sake".
• Collaborate Cross-Functionally: Work tightly with customers and product managers to break down complex features into actionable tasks, proactively surfacing edge cases and technical trade-offs before writing code.
• Elevate the Team: While primarily focused on independent delivery, you will amplify the team’s throughput through rigorous code reviews, sharing best practices, and actively unblocking peers.
• Build for Reliability: Ensure your updates are robust and integrate seamlessly into the broader Casca architecture. You will implement observability and automated testing to ensure your components run reliably in production.
• Our tech stack: TypeScript, React, NextJS, Postgres with Prisma, Python, AWS.

What you'll bring:

• Seasoned Expertise: 5+ years of software engineering experience with a proven track record of delivering significant projects in production SaaS environments.
• Startup Resilience: Recent experience (last 2–4 years) in fast-paced, high-velocity environments where you had to "lead from the front" and manage high-stakes trade-offs.
• Technical Mastery: Deep experience in web application development using relational databases and a quality-first mentality that results in clear, efficient, and low-defect code.
• Architectural Maturity: The ability to anticipate scaling challenges without over-engineering, building exactly what is needed for current scale while keeping code adaptable.
• Integrity & Alignment: A commitment to the "honorable businessperson" ideal—prioritizing transparency, honesty, and a "team above self" mentality even when stakes are high.
• Mission Resonance: A purpose-driven mindset that views your work as a "noble cause" to positively impact the lives of end-users.
• Operational Grit: Comfort with ambiguity and the ability to maintain high throughput and "operational resilience" in a rapidly evolving organization.
