Full Job Description
đź“‹ Description
- • 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.
- • You will be a core contributor to a new backend platform being built from scratch, spanning 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, event-driven processing using Kafka, cloud infrastructure on AWS, data transformation and aggregation layers, REST and WebSocket APIs, and observability and reliability.
- • The platform needs to run 24/7 without on-site support.
- • 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.
- • 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.
🎯 Requirements
- • 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
- • 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.
