About the role

Constantinople’s AI-native platform eliminates the need for expensive infrastructure, and replaces manual operational and compliance processes with AI at scale. By removing the operational complexity of banking, Constantinople enables our client banks to focus on their customers and the business of banking.

The Role

As a Senior Software Engineer at Constantinople, you will be a key technical leader in the engineering team — someone who takes pride in writing excellent code and equally in the systems, culture, and people around it. You will design, develop, and deliver complex software solutions that form the foundation of our banking platform, working closely with cross-functional teams to build software that sets new industry standards for reliability, scalability, and security.

This is a high-impact role for someone who wants to shape how AI-native banking infrastructure is built — at a company where engineering quality is a competitive advantage.

What You'll Do

Design and build critical features across Constantinople's core platform, taking end-to-end ownership from architecture through to production
Drive and deliver architectural improvements across projects, raising the engineering bar for the team
Collaborate with product, design, and data teams to solve complex technical challenges with pragmatic, well-considered solutions
Contribute to cross-team engineering initiatives and help establish best practices across the organisation
Improve internal tooling to enable data-driven analysis and reporting for the wider Constantinople team
Support a secure, performant, and highly reliable platform — and take shared responsibility for keeping it that way
Mentor and support fellow engineers, sharing knowledge and helping the team grow

Who You Are

You have 5+ years of professional software engineering experience, with a track record of owning significant systems in production
You have deep understanding of software design principles and scalable systems architecture
You have hands-on experience with Node.js and TypeScript in production environments
You are comfortable working across the stack — familiarity with React or React Native is a strong plus
You have experience with serverless AWS architectures (Lambda, API Gateway, DynamoDB, etc.) — this is highly desirable
Exposure to Domain-Driven Design or event-driven architectures is a bonus
You bring a collaborative mindset: you know when to lead, when to listen, and how to bring others along
You have experience or interest in fintech, banking, or regulated environments — though this isn't a hard requirement

Why Constantinople

Work on genuinely hard problems at the intersection of AI and financial services
Join a team that takes engineering craft seriously — we build for the long term
Significant scope for ownership and leadership in a high-growth environment
Competitive salary and equity — including participation in our Employee Share Option Plan (ESOP), giving you a real stake in the company's growth.
