We think this is a rare opportunity to be part of Spotify's groundbreaking journey as we evolve from an audio-first platform to also become a world-class video service. From offline playback to adaptive streaming with optimized video quality, you will be part of a team that defines how video will be consumed by hundreds of millions Spotify users. Our next challenge is to move more of our pre-render video pipeline, things like decoding, timing, synchronization and adaptive streaming from higher-level native integrations down into a performant, portable C++ stack. By driving this space alongside our existing players, you will shape the APIs, abstractions, and optimizations that make video on Spotify seamless everywhere: across iOS, Android, desktop, and beyond. We think you have many years of solid hands-on experience with video in code, from transcoding, streaming, demuxing, to adaptive bitrate selection and presentation of frames and audio samples. With that type of background this is a very good opportunity to expand your impact to help us at Spotify drive innovation in a space that's becoming increasingly vital to our growth. Joining us now will enable you to greatly influence our journey and make a lasting impact for the years to come. You will be joining an environment with a lot of collaboration, innovation and cross-functional teams that deliver seamless, high-quality video experiences. Your role is to provide the right APIs and implementations to allow all of those teams to serve a first class video experience every time. If you are ready to make an impact and push the boundaries of video technology, we would like to get in touch! What You'll Do Be part of a dynamic team focusing on creating a world-class mobile video experience, optimized for low-bandwidth environments and seamless on-the-go usage. At Spotify, we champion the perfect blend of strategy, creativity, and hands-on coding to drive innovation and deliver exceptional user experiences. Being a technical leader means that you are actively coding (in C++ with Swift and/or Kotlin), writing easy to understand documents and presenting for larger groups and key leaders. Debug complex performance issues across operating systems, device types, and networks. Optimise Spotify's AV stack by driving pre-render logic from platform-specific frameworks like AVFoundation into a cross-platform core to reduce duplication and increase consistency and device reach. Design and implement low-level C++ video components that handle decoding, synchronization, and adaptive playback with minimal overhead. Share expertise in low-level video systems, raising the bar across Spotify engineering. Who You Are A seasoned professional with a proven track record in senior roles, bringing a wealth of expertise and leadership to the table. Passionate about coding and hands-on problem-solving, while actively shaping and driving key strategic decisions. Strong understanding of decoding, synchronization, adaptive bitrate streaming, and frame-level control. Over 8 years of deep, hands-on experience in the video playback domain. Experience with platform-level frameworks like VideoToolbox, MediaCodec, or AVFoundation internals and motivated to generalize that work into reusable C++ systems. A deep understanding of video streaming technologies, with expertise in delivery protocols and the nuances of modern streaming ecosystems. Passionate about building foundations that empower Spotify teams to scale video to hundreds of millions of users. Where You'll Be We are a distributed workforce enabling our band members to find a work mode that is best for them! Where in the world? For this role, it can be within the EMEA region in which we have a work location and is within working hours. Working hours?

Mission The mission of Speechify is to make sure that reading is never a barrier to learning. Over 50 million people use Speechify's text-to-speech products to turn whatever they're reading - PDFs, books, Google Docs, news articles, websites - into audio, so they can read faster, read more, and remember more. Speechify's text-to-speech reading products include its iOS app, Android App, Mac App, Chrome Extension, and Web App. Google recently named Speechify the Chrome Extension of the Year and Apple named Speechify its 2025 Design Award winner for Inclusivity. Today, nearly 200 people around the globe work on Speechify in a 100% distributed setting - Speechify has no office. These include frontend and backend engineers, AI research scientists, and others from Amazon, Microsoft, and Google, leading PhD programs like Stanford, high growth startups like Stripe, Vercel, Bolt, and many founders of their own companies What You'll Do Lead the design, architecture, and development of native Windows desktop applications using Windows App SDK, WinUI (or related UI frameworks), C#, XAML, and - when needed - C++. Define and enforce best-practices for Windows desktop development across the codebase: code architecture, performance, memory usage, responsive UI, cross-version compatibility (Windows 10/11+), and maintainability. Drive accessibility efforts: integrate and validate support for accessibility APIs (e.g. Microsoft UI Automation or other relevant Windows accessibility frameworks), ensure UI controls, focus management, keyboard navigation, screen-reader support, and usability for users with disabilities. Collaborate closely with product designers, UX researchers, QA, and other stakeholders to shape feature planning, UI/UX architecture, and long-term roadmap for the Windows platform. Take ownership of full lifecycle of features: conception design implementation testing release maintenance. Ensure quality, reliability, and consistency across releases. Identify, diagnose, and resolve complex bugs, performance bottlenecks, memory leaks, rendering issues, or compatibility problems - and propose robust architectural or design solutions. An ideal candidate should have Required: 3+ in Windows desktop application development using Windows App SDK, WinUI (or similar), C#, XAML - and ideally additional experience with native Windows code (C++, Win32/WinRT/COM). Deep understanding of Windows application architecture, including interop between managed code (.NET) and native code. Proven track record of designing, building, and shipping production-quality desktop applications, with an emphasis on reliability, performance, scalability, and maintainability. Strong experience with accessibility APIs on Windows (e.g. Microsoft UI Automation or similar), and a dedication to building accessible and inclusive software. Excellent software engineering fundamentals: OOP, design patterns, data structures, algorithms, memory management, multi-threading or asynchronous programming (where relevant). Experience leading technical design, mentoring other engineers, conducting code reviews, and making architecture-level decisions. Strong communication skills; ability to articulate tradeoffs, collaborate with cross-functional teams, and drive consensus. A user-centric mindset: focus on building polished, intuitive, and accessible experiences for end users. Preferred / Bonus: Experience with writing automated tests for UI - unit tests, integration tests, UI automation tests; familiarity with relevant testing frameworks. Experience with performance optimization for desktop apps (memory usage, startup time, rendering performance, high-DPI support, responsiveness under load). Experience with localization/globalization, right-to-left UI support, internationalization, accessibility for multiple regions. Familiarity with telemetry, analytics, crash reporting, logging, and error monitoring in desktop applications. Previous experience in shaping CI/CD workflows, release pipelines, and deployment strategies for desktop applications. Demonstrated ability to take ownership of feature areas or modules and drive them long-term, including maintenance, refactoring, and technical debt management. What we offer A high-impact role: you will define architecture, shape the future of our Windows product, and directly influence what millions of users see and experience. A collaborative, flat-structure engineering culture - you are not just a coder, but a builder and a decision-maker. Opportunities to lead - mentor others, steer technical direction, and grow into broader technical leadership (e.g. Tech Lead, Architect). Flexibility, autonomy, and responsibility: you define how to solve problems, own features end-to-end, and contribute to long-term product vision. A purpose-driven mission: building software that's reliable, accessible, and user-centered - making a real difference for people. Think you're a good fit for this job? Tell us more about yourself and why you're interested in the role when you apply. And don't forget to include links to your portfolio and LinkedIn.
