The Role
This is your chance to build software that powers how the world pays. We're looking for a technically strong Senior Software Engineer to join Fulcrum Digital's engineering team on one of our top client engagements — a global leader in payments technology whose platforms help business users everywhere make faster, smarter, data-driven decisions. You'll be at the center of financial services innovation, helping reimagine how mission-critical, cloud-native systems scale to serve some of the world's biggest markets. Based in Dublin, Ireland, with a hybrid working arrangement.
You'll help shape system architecture and non-functional requirements, including scalability, performance, security, and reliability, for platforms that businesses across the globe depend on. You'll work closely with cross-functional teams to solve complex technical challenges, lead team-level design, and ship scalable services, APIs, and analytics-driven capabilities using Java, Databricks, cloud platforms, and modern data technologies. It's a small, agile, high-trust team, where every engineer owns outcomes end-to-end, from ideation through production.
Why This Role
- Work on mission-critical payments infrastructure used by businesses around the world
- Tackle large-scale, high-stakes financial data and analytics challenges

- Grow with Fulcrum Digital's expanding footprint across Banking, Financial Services, and Insurance (BFSI)
What You'll Do
- Lead team-level system design, including high-level design, detailed design, API contracts, data flows, service interactions, integration patterns, and nonfunctional requirements such as scalability, reliability, performance, security, and operability
- Partner with lead engineers and architects to align team-level implementations with broader platform architecture, modernisation goals, engineering standards, and long-term maintainability
- Develop and optimise data-intensive applications and analytics capabilities using Databricks, Spark, and related technologies to process and deliver data at scale
- Serve as a hands-on technical contributor, designing, coding, testing, debugging, and delivering production-quality software across the full engineering lifecycle
- Identify and resolve performance bottlenecks across services, APIs, data processing workloads, and user experiences
- Collaborate with cross-functional teams to translate business requirements into scalable technical solutions
- Mentor junior and mid-level engineers through technical guidance, pairing, code reviews, documentation, and knowledge sharing
- Contribute to a collaborative engineering culture by modelling ownership, clear communication, continuous learning, pragmatic decision-making, and high standards for software quality
- Improve engineering quality through code reviews, design reviews, automated testing, secure coding practices, observability, performance tuning, CI/CD practices, and production readiness
- Troubleshoot complex issues across application, service, API, data, and cloud layers, driving root cause analysis and implementing durable solutions that improve platform reliability and supportability
Requirements
Requirements
- Mandatory: Java, Spring Boot, RESTful APIs
- 6+ years of software engineering experience building scalable, distributed systems and cloud-native applications in an agile environment
- Exposure to TypeScript/React, SQL, and Databricks/Spark/PySpark for data pipelines is a plus
- Proven ability to lead team-level design, evaluate technical trade-offs, and translate business needs into secure, maintainable solutions
- Strong collaboration, communication, and problem-solving skills, comfortable working through ambiguity
- Bachelor's degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience
