Senior Java Engineer - Data Platform and Insights

Hawk-Eye Innovations

Principal Java Engineer - Backend Platform Hawk-Eye Innovations - Budapest Salary: HUF 1.8M - 2.6M per month Contract: Full-Time, Permanent Location: Hybrid - minimum 2 days per week in office, Budapest ABOUT THE ROLE The Principal Software Engineer (Full-Stack, Backend-leaning) is a senior engineer responsible for the backend architecture, data pipelines, and API layer of a new sports technology product, while remaining capable of contributing to frontend development as needed. This role sits within a small, fast-moving product engineering team and requires someone comfortable owning end-to-end technical delivery across the stack, with backend and data work as the primary focus. WHAT YOU’LL BUILD You will be a core contributor to a new backend platform being built from scratch. The work spans the full data journey - from ingestion at the edge through to storage, transformation, and delivery to end users. Key areas of focus include: * Low-latency data pipelines that ingest and process live sports tracking data, with strict latency requirements for time-critical outputs delivered to coaches and analysts in near real-time. * Event-driven processing using Kafka for streaming data and control messages between on-site devices and cloud services, handling both fast-path live outputs and asynchronous post-processing workflows via SQS and AWS Batch. * Cloud infrastructure on AWS, including Greengrass for edge-to-cloud orchestration, S3 for video and data storage, and Lambda for lightweight processing tasks. * Data transformation and aggregation layers that normalise tracking outputs, store them in a data lake, and make them available to downstream consumers via clean API contracts. * REST and WebSocket APIs that serve both a live data product for immediate consumption and an insights portal for historical analysis and performance comparison. * Observability and reliability - instrumentation, logging, and tracing are built in from the start, not bolted on. The platform needs to run 24/7 without on-site support. KEY RESPONSIBILITIES * Design and build backend services and APIs (REST/WebSocket) supporting data ingestion, transformation, and delivery to frontend and downstream consumers, with particular attention to latency and throughput given real-time processing requirements. * Own data storage and pipeline architecture, including integration with streaming/event infrastructure. * Implement authentication and authorisation in line with the team's chosen cloud identity and access management approach. * Provide technical direction and review for frontend development (React/TypeScript), working closely with frontend engineers to align on approach, component contracts, and data shapes - this is a collaboration and oversight function rather than day-to-day frontend delivery. * Collaborate closely with computer vision/data science engineers to define and consume data contracts. * Participate in technical decision-making for a product in active development, including architecture choices with long-term implications for scale, latency, and maintainability. * Contribute to technical leadership of the wider engineering team, given the seniority of this role. SKILLS AND EXPERIENCE * Strong backend engineering background with production experience in Java (required). * Demonstrated experience building low-latency, high-throughput systems - this is a core requirement, not a nice-to-have. * Working knowledge of a modern frontend framework such as React/TypeScript, sufficient to review and direct frontend work rather than deliver it independently. * Experience with cloud infrastructure and event-driven architectures (e.g. Kafka or equivalent streaming technology). * Experience designing and evolving API contracts (OpenAPI or similar) in a fast-moving, still-evolving product environment. * Familiarity with modern cloud identity and access management approaches (e.g. AWS Cognito or equivalent) is a plus. * Strong communication skills - able to work directly with product and cross-functional stakeholders, and to mentor or direct engineers outside their own core discipline. * Comfortable with ambiguity: this is a build-phase product with evolving scope and infrastructure decisions still being finalised. BENEFITS AND PERKS * Annual leave in line with Hungarian labour law * Hybrid working - minimum 2 days per week in office * Sony Group perks - discounted tickets and events * Cafeteria allowance: SZEP Card, nursery/kindergarten support, MOL Bubi Pass * Private medical, life and accident insurance, dental discounts * Seniority awards and Employee Assistance Programme * All You Can Move fitness pass option EQUAL OPPORTUNITY EMPLOYER Hawk-Eye is committed to fostering an inclusive and diverse workplace.
