Software Architect - Platform & Applications

About the job Beatgrid is redefining cross-media measurement with breakthrough deep-tech innovation. Built on our own Automatic Content Recognition (ACR) technology – the world’s only hybrid of audio fingerprinting and watermarking – we provide deterministic, privacy-first insights that reveal true ad effectiveness across TV and digital platforms like Netflix and YouTube. Trusted by global leaders such as Google, Amazon Prime, Disney+, and Netflix, we set a new standard for accuracy and transparency in an increasingly fragmented media landscape. As a Software Architect, you’ll play a key role in designing and evolving the technology behind our measurement platform and applications. You’ll work hands-on across the full solution, from designing software architecture and server-side development through APIs and security layers to the multiplatform and native Android/iOS applications, bringing features through to production. You’ll contribute to technical direction, improve our existing systems and build new capabilities using modern technologies and AI-assisted engineering tools. This is an opportunity to have a direct impact on the technology behind an ambitious deep-tech company and help build solutions that no other company has built. About you Responsibilities Design and deploy software architecture across Beatgrid's platform and mobile applications, translating product requirements into scalable and maintainable solutions.Work hands-on across the full technology stack, including backend and platform services, APIs, databases and mobile applications - directly contributing to implementation rather than operating only at an architectural level.Own features end-to-end - from understanding requirements and domain modelling through architectural design, backend implementation, mobile development, testing, deployment and ongoing system, software and application maintenance.Own the connection between the platform and mobile applications, ensuring that features and changes are designed and implemented across the relevant layers, from backend services and APIs through to Android and iOS applications. Develop and maintain backend services and APIs, with a strong focus on clean architecture, security, scalability, performance, reliability and cost efficiency.Contribute to Android and iOS development, working with Kotlin, Swift and Kotlin Multiplatform, including the existing mobile codebase and UI where required. Work closely with the CTO, Chief Architect and engineering teams to make architectural decisions, establish technical direction and continuously improve the platform.Maintain and improve the existing codebase, identifying technical gaps, performance bottlenecks and opportunities to simplify and automate development.Use modern AI-assisted engineering tools to accelerate development, automate repetitive engineering work and improve the quality and maintainability of software.Drive improvements in performance, scalability, reliability and infrastructure costContribute to code reviews, testing, CI/CD and production support, ensuring reliable software throughout its lifecycle. Qualifications Skills and experience Strong experience in software architecture, system design and domain modelling, with the ability to translate business and product requirements into robust technical solutions.Strong backend engineering experience - ideally with Java/ Kotlin and Spring Boot, APIs, relational databases and distributed/cloud-based systems.Experience designing and building scalable and maintainable backend/platform services, deploying and operating applications in cloud environments.Strong understanding of API design, data structures, and distributed systemsExperience working across application layers (Android/iOS development using Kotlin, Swift and Kotlin Multiplatform) and integrating backend/platform services with mobile applications.Strong understanding of performance optimisation, concurrency, scalability and reliability across backend and client applications.Experience with modern engineering practices including automated testing, CI/CD, code reviews and production support.Experience using AI-assisted development tools and automation to improve engineering productivity and software quality.Strong problem-solving and analytical skills, with the ability to balance technical quality, business requirements, performance and cost.Excellent communication and the ability to work independently while collaborating closely with product, engineering and architecture teams. What’s in it for you Perks Shape the architecture behind breakthrough technology that’s transforming the future of cross-media measurement, with opportunities to contribute to innovative projects including our latest work with agentic AI.Have a direct impact on Beatgrid’s technology direction, shaping scalable platform, backend and mobile solutions.Work hands-on with modern technologies and engineering practices across backend, cloud, APIs and mobile development, with opportunities to leverage AI-assisted development and automation.Enjoy a vibrant office in the heart of The Hague, with cafés, culture, and city life nearby.Stay active and healthy with our on-site fitness club and professional instructors.Flexible working with work-from-home arrangements.Competitive compensation + Employee Stock Option Plan (ESOP) — share in the value you help create and benefit from future growth and exit opportunities.
