Job description

Senior Full Stack Software Engineer – Trading Technology

Dublin | On-site

Excellent Salary + Bonus + Benefits

The Company

We are partnering with a leading global financial technology organisation to hire an experienced Full Stack Software Engineer for its Dublin engineering team.

Technology sits at the core of the business, with engineers responsible for building sophisticated, performance-critical applications used across global financial markets.

This is a highly technical environment suited to an engineer who enjoys hands-on development, complex problem solving and building software where performance, reliability and usability genuinely matter.

The Opportunity

This is a particularly interesting hire and will be one of the first dedicated Full Stack Software Engineering positions of its kind within the Dublin team.

The role is heavily focused on application development, with approximately 70% frontend and 30% backend engineering.

You will design and build high-performance, real-time applications used directly by trading and business teams. The work spans intuitive user interfaces, data visualisation and analytics through to the APIs and backend services supporting those applications.

This is not a pure frontend position.

We are looking for a strong Software Engineer who has deep application-development experience but is equally comfortable understanding how systems work across the stack.

What You'll Be Doing

• Build responsive, intuitive interfaces for real-time data, analytics, visualisation and reporting.
• Develop highly interactive applications where performance and reliability are critical.
• Contribute to backend services and APIs using technologies such as Java, C++ or C#.
• Design and integrate REST APIs, WebSockets and other real-time data services.
• Work with relational and high-performance databases such as PostgreSQL, MySQL or similar technologies.
• Optimise application performance, responsiveness and scalability.
• Work directly with end users to understand complex requirements and turn them into effective technical solutions.
• Contribute to architecture, system design and technical decision-making.
• Take ownership of features across the full development lifecycle, from initial design through to production.

What We're Looking For

We're particularly interested in experienced Software Engineers who have built complex, data-intensive applications rather than purely content-driven websites.

You should have strong experience across:

• React and modern frontend application development.
• Building complex web-based applications and user interfaces.
• Application architecture, state management and frontend performance.
• REST APIs and ideally WebSockets or other real-time technologies.
• Backend development using Java, C++ or C#/.NET.
• Databases such as PostgreSQL, MySQL or similar.
• Modern software engineering practices, including Git, testing and code review.
• Experience with technologies such as Redux, GraphQL, D3.js or other data visualisation libraries would be particularly relevant.
