Principal Java Engineer - Backend Platform Salary: £76,340 - £100,340 Per Annum Contract: Full-Time, Permanent Location: Hybrid - minimum 2 days per week in office, Basingstoke/London/Bristol 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 * 25 days annual leave (excluding bank holidays) * Enhanced pension scheme with 5% matching * Hybrid working model * Complimentary Unmind wellbeing app * Onsite gym (Basingstoke) * Access to sporting events and tickets * Sony Group Company discounts EQUAL OPPORTUNITY EMPLOYER Hawk-Eye is committed to fostering an inclusive and diverse workplace. We ensure all employees are treated fairly, regardless of gender, marital status, race, nationality, religion, age, disability, or union membership. We value diversity and strive to create an environment where everyone can reach their full potential. APPLY TODAY If you are passionate about building high-performance backend systems and want to work on real-time data products at scale, we would love to hear from you.

Major offices in Sweden (HQ), Greece, India, Canada, Israel, Poland, UK, and Uruguay. The Team: Platform Services At the heart of this technology is the Platform Services team, a highly technical group responsible for maintaining and evolving the foundational aspects of the Etraveli Group platform. Our mission is to ensure we have a robust environment to build, deliver, and run services—from the very first lines of code in a project to maintainable services running in production, whether in AWS or our own datacenters. We manage our CI/CD setup and cloud infrastructure using Infrastructure as Code (IaC), providing project templates and architectural support to development teams and strategically important projects. Today, the team consists of a collaborative mix of cloud infrastructure specialists and tech-focused senior developers. The Role As we grow and expand our support for new teams and projects, we are looking for a Senior Engineer or Hands-on Architect to strengthen our ranks. While the team handles infrastructure, your focus will be on the software side of building services: code, design, system architecture, and CI/CD. In this role, you will certainly draw boxes and arrows on whiteboards to map out designs, but more importantly, you will write and update the code within our templates and CI/CD pipelines to support our developers. You will be a key voice in discussions—both within the team and across the organization—on how to best design and solve complex technical tasks. Requirements To be a good fit for this role, we believe you possess the following qualifications: Experience: At least 10 years as a software developer and/or architect (likely more). Java Expertise: Extensive experience as a Java backend developer, very comfortable in a senior capacity. Polyglot Mindset: Experience with programming languages beyond just Java. Mentorship: You enjoy supporting other developers and can discuss complex software solutions with both teams and stakeholders. CI/CD & Kubernetes: At least some experience with CI/CD (and a willingness to become an expert) and a strong understanding of Kubernetes—including the ability to write and troubleshoot manifest files independently. Broad Technical Interest: An interest in the underlying infrastructure required to run services, as well as a passion for service architecture and IaC (without being "married" to a single tool). Tech Stack Knowledge: Meaningful experience in several of the following: AWS, Linux, shell scripting, Git, Jenkins, Groovy, Typescript, React, Python, MySQL, Couchbase, Kafka, RabbitMQ, Terraform, CDK, CloudFormation, Gradle, Spring Boot, Kubernetes, Helm, OpenSearch, Prometheus, Grafana, observability, security, networking, and testing. Communication: Comfortable speaking and writing in English. Ready to take off from day #1 Thorough On Boarding Process We are building a stellar onboarding adventure just for you, spanning your first 120 days, including access to learning resources, Q&A sessions with our CEO and a buddy program.
