Back End Developer

We’re hiring: Senior Backend Engineer (Fintech / AI / Banking Infrastructure)

Location: Hybrid

Company: Advance

About Advance

Advance is a fintech startup tackling one of the most painful and underserved problems in the insurance industry: money movement, reconciliation, and banking workflows that were never designed for modern scale.

We’re building next-generation vertical banking infrastructure for insurance - combining deep domain expertise, robust financial systems, and AI-driven workflows that replace manual, slow, and error-prone processes.

This is a rare opportunity to work on real financial rails, real customers, and real impact, while shaping how AI is embedded into core banking systems from day one.

The Role

We’re looking for a Senior Backend Engineer to play a key role in designing and building the next generation of Advance’s banking platform.

You’ll work on mission-critical systems that move money, manage accounts, and power intelligent workflows with AI as a first-class citizen, not an afterthought. This is a highly hands-on role with close collaboration across product, frontend, and AI engineering.

What You’ll Do

• Design and build core backend services for a vertical banking platform
• Own end-to-end development of scalable, secure, and reliable financial systems
• Develop and integrate AI-driven workflows (automation, decisioning, reconciliation, agent-based flows)
• Work extensively with modern AI tools and frameworks to accelerate development
• Architect APIs and data models for complex financial and insurance use cases
• Collaborate closely with frontend engineers (React / Next.js)
• Participate in technical decision-making and help shape architecture and engineering culture
• Maintain high standards for code quality, observability, security, and performance

Tech Stack (What You Should Be Comfortable With)

• Backend: Python (FastAPI or similar)
• Cloud & Infrastructure: AWS (K8s, serverless, managed services, IAM, networking)
• Databases: PostgreSQL (schema design, migrations, performance)
• AI & Automation:
• Building or integrating AI workflows
• Working with LLMs, agents, or orchestration frameworks (preferably LangGraph/Strands and AWS Bedrock)
• Strong intuition for where AI adds real value (not just demos)
• Large Scale Systems: Event-driven systems, payments, banking APIs, fintech or insurtech experience

What We’re Looking For

• 8+ years of experience as a backend or platform engineer
• Strong system design skills and experience owning production systems
• High ownership, independence, and accountability
• Curiosity and enthusiasm for AI-native development
• Pragmatic mindset: you know when to move fast and when to be precise
• Fintech, banking, payments, or insurance experience is a strong plus (but not required)

Why Join Advance

• Build real banking infrastructure, not dashboards
• Work on systems that directly affect how billions of dollars move
• AI is core to the product, not a side project
• Early-stage impact with high ownership and technical influence
• Collaborate with a small, senior, highly motivated team
