Soris

ABOUT SORIS We are a stealth technology company building at the intersection of foundational AI and systems design for real-world impact. Our mission is bold: to reimagine one of the largest and most entrenched industries on the planet, creating an entirely new model that is faster, fairer, and fundamentally better for humanity. Unlike wrapper companies or point solutions, we are building a full-stack AI platform from the ground up; one that is agentic, vertically integrated, and designed for scale. This gives us the rare ability to solve problems others can’t touch, operating with orders-of-magnitude more efficiency than legacy systems. Our founding team has scaled category-defining companies in frontier tech, aerospace, mobility, and AI. We’ve led organizations from zero to multibillion-dollar valuations, pioneered new industries, and built products that reshaped how people live and move. Now we’re assembling a small, fiercely talented team to take on our most ambitious challenge yet. Joining us means working on cutting-edge research with direct application, where your code doesn’t sit in a lab, it changes lives. You’ll be part of an environment that values intellectual rigor, creative rebellion, and the courage to build what others say is impossible. This is a once-in-a-generation opportunity to help design and deploy the infrastructure of the future. We’ve raised capital in record time, and are scaling our foundational team now. If you’re motivated by hard problems, high impact, and the chance to leave a legacy, we’d love to talk. THE ROLE We’re looking for a Senior Software Engineer with backend engineering expertise to join our Engineering team. You’ll work alongside the CTO and other engineers to build Soris’ first MVP. You will be doing foundational work such as building our core APIs that interact with our agentic systems, building a deployment infrastructure that allows rapid experimentation, architecting our RAG pipelines and architecture, and setting best practices for the entire engineering organization. This is a ground-floor opportunity where your work will directly shape the platform, culture, and impact of Soris. Candidates with a good fit for this role: * Want to ship fast, iterate, and own outcomes. * Thrive in ambiguity, asking questions and solving problems across the stack. * Believe in building systems that are secure, transparent, and human-friendly. WHAT YOU’LL DO * Design and build core backend systems and APIs that power our Soris products. * Develop scalable data pipelines and storage systems for high-availability agentic systems. * Collaborate with the product division to integrate agentic workflows into the core platform. * Work closely with early stakeholders to deliver solutions that solve real pain points. * Contribute across the product lifecycle: architecture, implementation, testing, deployment, and monitoring. REQUIREMENTS * 5+ years of experience building backend services from end-to-end. * Strong proficiency in Python, Go, Rust, or a similar language. * Demonstrated expertise in system design and development. * Experience with databases (SQL/NoSQL), cloud infrastructure (AWS/Azure/GCP), and CI/CD pipelines (GitHub actions). * Experience with Infrastructure-as-Code (Terraform is a huge plus!). NICE-TO-HAVES * Strong experience building or integrating AI agents into production systems. * Background in highly regulated industries (HIPAA, SOC2, HITRUST, PCI, etc.). * Experience with payment rails (Stripe, SVB, Square etc.). * Experience optimizing payment flows, financial reconciliation, or compliance-heavy data pipelines. * Contributions to early-stage startups or small teams where wearing multiple hats was key. * Knowledge of security and compliance best practices for handling sensitive customer and financial data. ENGINEERING CULTURE AT SORIS Our values guide how we work: * Extreme Ownership: We own outcomes, not just code. At Soris, we never say “that’s not my job”. * Always Be Curious: Ask questions. Explore new ways. * Go Farther Together: Collaboration beats silos. WHY JOIN US? * Competitive compensation package, including salary and equity. * Benefits include employer-covered health insurance for you, your spouse, and partially for children * Be part of an engineering team with massive influence on product, culture, and direction. * Work with cutting-edge AI agents and modern tech stacks.

Hawk-Eye Innovations

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.
