Job Description: JOB DESCRIPTIONOur Purpose Title and Summary
Senior Backend Software EngineerOverview
Founded by Mastercard and IBM in 2018, Truata specialises in privacy-enhancing technologies for privacy risk assessment, de-identification, and true anonymisation of data.
We were among the first companies in the EU to achieve ISO 27701 certification — the international standard for data privacy management — through independent accreditation.
In 2023, Mastercard acquired full ownership of Truata, which continues to operate as an independent entity within the Mastercard Data and AI Strategy organisation.
Truata is now seeking a Senior Backend Software Engineer to join our growing Engineering team in Dublin, Ireland.
This is a key engineering role focused on driving the development of innovative, privacy-first data solutions that scale.
Role
As a Senior Backend Software Engineer at Truata, you will architect and build our cutting-edge, GDPR-compliant big data analytics platform, empowering enterprises to unlock actionable insights in real time.
This role demands technical mastery in designing scalable microservices (SpringBoot, Java 17), handling complex data workflows (wrangling, anonymization, analytics), and deploying cloud-native PaaS solutions that prioritize security and scalability.
You'll thrive in a fast-paced, team-first environment, collaborating closely with cross-functional teams to translate challenging requirements into robust and scalable code, while collaborating with peers, and communicating clearly with stakeholders.
A passion for problem-solving, intellectual curiosity, and a high sense of ownership are essential, you'll be expected to adapt to shifting priorities, drive innovation through pair programming and code reviews, and foster a culture of growth where teamwork, proactivity, and high-quality, maintainable solutions are expected.
Why Join Us?
•Own the Architecture, Lead the Team: Influence design decisions, own the software end to end, and foster a culture of growth by collaborating with highly talented engineers.
• Move Fast, Stay Agile: Work in a startup-like environment where rapid iteration meets rigorous quality standards.
• Collaborate Across Functions: Partner daily with product managers, data scientists, data engineers, and DevOps engineers to solve challenging problems.
• Impact at Scale: Build systems processing huge amounts of data, deployed on our cloud-native Azure infrastructure.
• Grow Together: Learn from experts while sharing your knowledge through pair programming, code reviews, and team meetings.
Key Responsibilities
• Architect & Deliver: Design reactive micro-services (SpringBoot, Java 17) and Spark pipelines that balance scalability, security, and speed.
• Write Maintainable Code: Prioritise readability, testing, and CI/CD automation while keeping up to date our systems for performance gains.
• Translate Ambiguity into Action: Collaborate with product and data teams to clarify requirements, then lead technical discussions to align priorities.
• Optimise Relentlessly: Tune code performance, design database storage models (SQL/NoSQL), streamline distributed workflows, and implement observability for high-throughput systems.
• Grow & Learn by doing: Conduct code reviews, share knowledge via documentation, and empower engineers to grow into performant contributors.
Contribute to strategic planning and help shape Truata's long-term technology roadmap.

• 5+ years building enterprise-grade backend systems (micro-services, REST APIs, distributed data platforms).
• Strong and solid knowledge of software engineering principles and practices.
University degree in Computer Science or equivalent is a MUST.
Advanced degree preferred.
• Mastery of SpringBoot 3+, Java 17+, Git, and CI/CD pipelines (GitLab/Jenkins/GitHub, or similar).
• Proven experience designing fault-tolerant systems, optimising queries at scale, and containerising apps (Docker/K8s).
Soft Skills:
• Proven communicator: Explain complex technical concepts to non-technical stakeholders and lead cross-functional debates.
• Adaptability: Thrive in ambiguity, pivot priorities without sacrificing quality, embrace feedback, and take ownership of deliverables.
