Data Engineer ( Scale Up )

Data Engineer Location: Belfast Working Model: Hybrid Engagement: Permanent OCHO is partnering with a scaling technology business building a cloud native platform integrated with purpose built hardware. This is a product operating in high trust, real world environments where data integrity, reliability, and security are non negotiable. The platform foundations are in place. 2026 is about scale, robustness, and insight. This hire sits at the centre of that evolution. The Opportunity This is not a reporting layer role. This is production data engineering. You will be responsible for how data moves from edge devices into the cloud, how it is structured, stored, and governed, and how it ultimately becomes usable insight. You will work closely with backend, platform, and firmware engineers to ensure the flow from device to cloud is secure, traceable, and performant. If you care about correctness as much as speed, this will resonate. What You'll Be Doing * Designing and building scalable data pipelines ingesting data from hardware and edge systems * Working with high volume event driven data, time series data, and rich metadata * Ensuring integrity, auditability, and traceability across the full data lifecycle * Defining data contracts and schemas in collaboration with engineering teams * Supporting analytics, operational insight, and reporting use cases * Optimising storage strategy, retention policies, and performance * Monitoring and improving production pipeline reliability * Contributing to data architecture decisions as the platform matures You will influence how the data layer is structured as the business scales. What We're Looking For * Commercial experience as a Data Engineer or in a data focused backend role * Strong SQL capability and sound data modelling fundamentals * Experience building and operating production grade data pipelines * Cloud exposure across AWS or Azure * Understanding of event driven or streaming architectures * Strong focus on governance, security, and data quality * Comfortable collaborating across software and hardware aligned teams Nice to Have * Experience working with IoT or device generated data * Exposure to telemetry, video, or media data * Experience in regulated or security sensitive domains * Familiarity with message queues or streaming platforms Why Join Now The platform is entering its next phase of scale. The architectural decisions made this year will directly impact long term reliability, trust, and product maturity. This is a chance to influence that trajectory.
