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 role is highly

hands-on and involves close collaboration with 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 (e.g. intelligent automation, decisioning,
  • reconciliation, agent-based flows)
  • Work extensively with modern AI tools and frameworks to accelerate development and
  • improve system capabilities
  • Architect APIs and data models that support complex financial and insurance use cases
  • Collaborate closely with frontend engineers on React / Next.js-based applications
  • Take part in technical decision-making and help shape the engineering culture and
  • architecture
  • Ensure high standards for code quality, observability, security, and performance

Tech Stack (and What You Should Be Comfortable With)

  • Backend: Python (FastAPI or similar)
  • Infrastructure & Cloud: AWS (serverless, managed services, IAM, networking)
  • Databases: PostgreSQL (schema design, performance, migrations)
  • Frontend familiarity: React + TypeScript, Next.js (you won’t be a frontend engineer, but
  • you’ll work closely with it)
  • AI & Automation:
    • Experience building or integrating AI workflows
    • Working with LLMs, agents, or orchestration frameworks
    • Strong intuition for where AI adds real value (not just demos)
  • Bonus: Event-driven systems, payments, banking APIs, or fintech/insurtech experience

What We’re Looking For

  • 8+ years of experience as a backend or platform engineer
  • Strong system design skills and experience owning complex services in production
  • Proven ability to work independently and take ownership
  • Curiosity and enthusiasm for AI-native development
  • Pragmatic mindset - you know when to move fast and when to be precise
  • Experience in fintech, banking, payments, or insurance is a strong plus (but not required)
