Senior Full-Stack Engineer, Video Team

📋 Description

• • Solink is seeking a highly skilled Senior Full-Stack Engineer to join our dynamic Core Apps – Video Team. This pivotal role involves the comprehensive development and enhancement of Solink’s Video Management System (VMS) and its cutting-edge cloud video platform. You will be instrumental in shaping the entire video pipeline, from the intricate integration of cameras and streams to the delivery of sophisticated customer-facing video experiences, including live viewing, seamless playback, efficient investigation workflows, and robust export functionalities.
• • This position is ideally suited for a seasoned engineer who possesses a strong command of full-stack development, exhibits a deep intuition for backend systems, and has the capacity to significantly influence technical strategy beyond the scope of individual tasks. You will be a key contributor to architectural decisions, provide mentorship to fellow engineers, and ensure the video platform's scalability, reliability, and efficiency as Solink continues its rapid expansion.
• • A core focus of this role lies in optimizing storage efficiency and mastering video encoding/decoding processes. We are actively searching for an individual who understands the critical real-world trade-offs between cost, quality, reliability, and performance inherent in managing large-scale video systems.
• • Your responsibilities will encompass designing, building, and maintaining full-stack features across Solink’s video applications, with a significant emphasis on backend services and systems integration, estimated at 60–70% of your workload.
• • You will be tasked with building and evolving fundamental video capabilities, including but not limited to: stream lifecycle management (ensuring camera connectivity, health, and state), developing engaging live and recorded video playback experiences, creating efficient video export and clip generation workflows, and enhancing investigation/search functionalities that rely on rapid and dependable video retrieval.
• • A key aspect of your role will involve developing and optimizing backend services and APIs that underpin video workflows across both edge and cloud environments, ensuring seamless communication and data flow.
• • You will collaborate closely with both edge and cloud components, including Linux-based edge devices and cloud services, to guarantee end-to-end system reliability and performance.
• • A significant part of your contribution will be dedicated to improving storage efficiency and the cost-performance ratio of video workflows. This includes refining retention policies, packaging strategies, transcoding/processing techniques, and enhancing operational visibility into these processes.
• • You will actively contribute to critical design decisions, meticulously balancing the imperatives of scalability, performance, reliability, security, and an exceptional developer experience.
• • This role requires close partnership with Product, QA, and other cross-functional engineering teams to effectively translate complex requirements into pragmatic, production-ready solutions.
• • You will play a vital role in mentoring and influencing other engineers through constructive code reviews, insightful design discussions, and proactive, informal knowledge sharing sessions.
• • Continuous improvement of team tooling, observability practices, and development processes will be a key objective, including the thoughtful exploration and adoption of AI-assisted workflows where they can demonstrably enhance productivity and product capabilities.
• • The ideal candidate will possess a strong foundation in modern web development, demonstrating proficiency with JavaScript/TypeScript and React (or comparable frontend frameworks).
• • Deep backend expertise, particularly with Node.js or similar technologies, is essential, encompassing robust API design, a solid understanding of distributed systems fundamentals, and a proven track record of ensuring production reliability.
• • Experience within the VMS/video surveillance domain is highly valued, including familiarity with camera systems, VMS concepts, video workflows, and the operational expectations of such systems.
• • Hands-on experience with key video streaming technologies such as RTSP, HLS, and WebRTC is a must.
• • Practical application of FFmpeg in production environments, whether for debugging pipelines, managing packaging/transcoding workflows, or integrating video processing into services, is crucial.
• • A strong grasp of video encoding/decoding fundamentals and their impact on storage footprint, cost, quality, latency, playback compatibility, and seek performance is required.
• • Experience working within Linux environments, particularly with edge devices or performance/IO-sensitive systems, is highly beneficial.
• • Comfort navigating, debugging, and contributing to codebases that include C++ and/or Rust is expected, even if not an expert in both.
• • Hands-on experience with cloud platforms, preferably AWS, and modern deployment methodologies like infrastructure as code, CI/CD, and containerization/serverless technologies, is necessary.
• • Proven experience with large-scale video storage and retention strategies, including tiering, lifecycle policies, segment management, and compaction/repacking, is important.
• • Familiarity with hardware acceleration and performance tuning for video workloads will be advantageous.
• • Exceptional problem-solving skills, a strong sense of ownership, and the ability to influence technical decisions are paramount.
• • Nice-to-have qualifications include experience with Kubernetes, cloud-native operations (observability, metrics, incident response, SLOs), scaling systems in high-growth environments, and an interest in AI/ML applications for product and team enhancement.
