Senior Python developer

About Client

Our client is a fintech startup tackling one of the biggest and most painful 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 tailored specifically for insurance - combining deep domain understanding, robust financial systems, and AI-driven workflows that automate and simplify what was previously manual, slow, and error-prone.

This is a rare opportunity to work on real financial rails, real customers, and real impact - while pushing the boundaries of how AI is embedded into core banking systems.

The Role

We're looking for a Senior Backend Engineer to play a key role in designing and building the next generation of our client'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

Requirements 

• 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)
