MUST BE BASED IN NORTHERN IRELAND
Have you designed systems that process vast volumes of data at enterprise scale? Have you influenced architectural direction across multiple teams? Are you comfortable operating as the technical authority in complex, cloud-native environments?
My client is seeking a Senior Staff Software Engineer to lead architecture and engineering strategy across high-impact, data-intensive platforms. This role sits at the intersection of hands-on engineering, architectural leadership, and technical influence at scale.
The Opportunity
As a Senior Staff Engineer, you will:
* Shape and evolve architecture across large, distributed systems
* Lead the design of high-volume, data-driven platforms in AWS
* Drive best practice in scalability, resilience, and performance
* Provide technical leadership across multiple engineering teams
* Influence long-term platform strategy and system design decisions
* Stay close to the code while operating at architectural altitude
This is a role for someone who has operated at genuine scale — not just contributed to it.
What We’re Looking For
Experience
* 12–15+ years in software engineering
* Proven experience delivering and shaping large-scale enterprise systems
* Track record of architectural leadership across major programmes or platforms
Core Technical Expertise
* Deep expertise in Java, including performance optimisation and concurrency
* Apache Spark (batch and streaming workloads)
* Streaming technologies (e.g. event-driven systems)
* Amazon Redshift
* Strong relational database expertise, particularly PostgreSQL
* Experience working with large volumes of structured and semi-structured data
Additional Strengths
* Experience building data platforms or real-time processing systems
* Comfort working across infrastructure, application, and data layers
What Success Looks Like
* Architectures that scale cleanly under heavy data load
* Clear technical direction across teams
* Reduced operational risk through strong system design
* High engineering standards embedded across the organisation
This is an opportunity to operate as a true technical leader — influencing direction, raising standards, and building platforms that perform at serious scale.
If you have any further questions on the role, please feel free to reach out to Brendan McCrory directly.
