Their products combine Java, AI, and modern web technologies to deliver clarity and speed for decision‑makers.

They’re estimated at nearly $30M annually and have 3 offices globally, with the view to grow their UK footprint. Having recently doubled down on AI‑driven tools, they are tackling the biggest pain points stakeholders have: information overload and poor decision‑making efficiency.

What You’ll Do

• Develop and enhance their core services built in Java (Spring Boot).
• Work on full‑stack features using React (or similar modern JS frameworks).
• Collaborate on new product initiatives, including AI‑powered tools.
• Contribute to architecture decisions and help shape the future.

Tech Stack

• Backend: Java (Spring Boot), Ruby on Rails (legacy), Golang, Python (AI services)
• Frontend: React, TypeScript
• Other: Kubernetes, modern CI/CD pipelines

What We’re Looking For

• Strong experience with Java and Spring Boot.
• Full‑stack skills with React or similar frameworks is desired.
• Bonus points for Kubernetes, cloud‑native development, or exposure to AI‑driven products.
• Someone curious, collaborative, and excited to work on modern, evolving products!
