About FinArb
FinArb is a data-driven analytics and AI consulting firm that builds automated, scalable solutions for complex business problems. We ship production applications and AI-powered products for clients across banking, finance, risk, healthcare, pharma, and education. Our engineering philosophy favors modern cloud-native platforms, robust fundamentals, and a "buy first, build the defensible core" approach — we pick the right tool for each problem rather than forcing one stack.
About the Role
You'll own features end to end — from data model and API to UI and deployment — across our web applications and AI products. This is a hands-on senior role: you'll architect and build full-stack systems, integrate LLM-driven capabilities (agents, retrieval, tool/function calling), and take responsibility for quality, performance, and shipping. You'll work in both TypeScript/Node and Python ecosystems depending on the engagement, deploy to AWS or Azure, and collaborate closely with data scientists, designers, and client stakeholders.
Responsibilities
- Design, build,



and ship full-stack features across frontend, backend, and data layers.
- Build and consume well-designed REST/GraphQL APIs and services; model the data behind them.
- Develop modern, responsive UIs and the server-side logic that powers them.
- Integrate LLM/AI capabilities into applications — agents, retrieval-augmented generation, tool/function calling, and orchestration.
- Deploy, monitor, and maintain applications on cloud infrastructure (AWS or Azure).
- Own code quality through reviews, testing, and sound engineering practices.
- Collaborate with data scientists, analysts, designers, and stakeholders to translate requirements into working software.
- Contribute to architectural decisions and continuous improvement of the team's standards and tooling.

Basic Qualifications
- Bachelor's or Master's in Computer Science, Engineering, or a related field — or equivalent practical experience.
- 3–5 years of ha
