Job Description
Senior Software Engineer (Web SDK Platform)
Apryse
The Role We are looking for a Senior Software Engineer to serve as a technical pillar for our client-side document SDK. This is not a standard UI/UX role; you will be architecting the engine that powers document rendering, programmatic manipulation, and collaborative workflows for millions of users. As a senior leader on the team, you will steward our "Core" minified engine while maintaining our open-source UI layer. You will be responsible for navigating deep technical ambiguity, writing comprehensive design documents, and making high-stakes trade-off decisions regarding performance, memory management, and API design. If you enjoy the challenge of working with WebAssembly, concurrent workflows (Web Workers), and complex binary file formats (PDF, DocX, XLSX), this role is for you. Responsibilities - System Architecture: Lead the design and evolution of the WebViewer SDK, ensuring a clean separation between our open-source UI (https://github.com/PDFTron/webviewer-ui) and our high-performance "Core" engine. - Technical Leadership: Drive the "Design Doc" culture. You will be responsible for planning and executing complex features, from programmatic redaction to real-time collaboration syncing. - Performance Engineering: Optimize the SDK to handle documents of extreme size and complexity, managing memory leaks, rendering bottlenecks, and expensive programmatic functions. - Cross-Functional Collaboration: Partner with Product, Sales, and Solution Engineers to translate high-level customer needs into robust technical roadmaps. - Mentorship & Quality: Set the bar for code quality through rigorous PR reviews, architectural guidance, and the promotion of strong testing fundamentals. - Developer Advocacy: Our customers are developers. You will ensure our APIs are intuitive, our documentation is world-class, and our SDK is a joy to integrate. - Customer experience is paramount to us. We regularly collaborate with software developers, project and product owners, UI/UX, support, sales, and solution engineer teams to design new features and improve user experience. - Our customers are other developers, so we research and utilize the latest technologies, write concise technical documentation, and informative blogs. Requirements - Experience: 5–10 years of professional software development experience, with a proven track record of shipping complex web-based products or platforms. - Architectural Mindset: Deep understanding of common design patterns and methodologies. You should be comfortable discussing the trade-offs between different state management patterns and API structures. - Web Fundamentals: Expert-level knowledge of JavaScript/TypeScript and how the web client-server model operates at a deep level (e.g., request lifecycles, browser rendering engines, and binary data handling). - Concurrency & Performance: Experience managing concurrent workflows, particularly with Web Workers and Web Assembly (Wasm).You understand how to offload heavy computation without blocking the main thread. - Testing Excellence: Beyond just "writing tests," you have a robust understanding of testing strategy. Experience with Playwright, Storybook, and Jest is preferred, but a mastery of testing fundamentals (unit, integration, and E2E) is required. - Communication: Exceptional technical writing and verbal communication skills. You can explain complex architectural trade-offs to both engineers and non-technical stakeholders. - Navigating Ambiguity: A proven ability to take a vague product requirement and turn it into a concrete, executable technical plan. Preferred Experience - Experience building SDKs, Libraries, or Open-Source projects where API stability and developer experience are paramount. - Familiarity with document-specific technologies (PDF specification, OOXML, or canvas-based rendering). - Experience with low-level languages (C++, Rust, or Go) that compile to Web Assembly. - Deep knowledge of Collaborative Frameworks (CRDTs,WebSockets, or operational transform). - Experience building accessible UIs - Experience with backend(Node.js, PHP, etc.). - Experience with databases (NoSQL or SQL). - Experience with mobile applications (Android / iOS). Benefits: - Competitive salary commensurate with experience & qualifications. - A comprehensive extended benefits package. - A great team environment and resources, supporting you to do the best work of your life and providing unlimited career growth potential. - Highly autonomous and entrepreneurial environment. - Annual recurring WFH allowance for you to purchase items you need for your home office. - On going support for learning development so you can continue to master your craft. - Work with the hardware you're most comfortable with (Windows or Mac) - Diverse and inclusive workplace where we all learn from each other. - Excellent work-life balance with a flexible remote work environment. Company Description As the industry-leading provider of document software development (SDK) technology powering everything from traditional desktop software to innovative web and mobile applications, at Apryse we are committed to delivering cutting-edge technology solutions that empower our clients to achieve their goals.
