Goldcast (a Cvent company) is an AI-powered B2B Video Content Platform that enables marketers to put video content at the heart of the customer journey. We’re building a browser-based, frame-accurate video editor that rivals desktop apps, using cutting-edge tech like WebCodecs, WASM, and Remotion.

Founded in mid-2020 at Harvard Business School, we have 400+ customers across tech, professional services, manufacturing, and finance to deliver engaging video content & digital events.

Role Overview

We’re seeking a highly skilled Senior Software Engineer II (SSE-II) to join our Content Lab — the team pioneering AI-driven video transformation at scale.

In this role, you’ll lead complex backend projects, focusing on distributed systems, real-time video processing, and media pipeline scalability. You’ll partner with product, design, and QA to deliver high-quality, maintainable solutions that enhance our AI-enabled video content platform.

This role requires deep technical expertise in video streaming technologies, backend architecture, and system performance, as well as a passion for mentoring engineers and driving engineering excellence.

In This Role, You Will:

Technical Ownership & Leadership

• Lead large, cross-functional projects involving multiple engineers, driving design, architecture, and execution from concept to production rollout.
• Design and implement high-performance backend systems that support video encoding, transcoding, and adaptive streaming at scale.
• Make architectural and design decisions that balance scalability, maintainability, and performance.

Video Systems Engineering

• Work with frameworks like FFmpeg, GStreamer, or similar to build efficient video pipelines handling multiple codecs (H.264, H.265, VP9, AV1) and formats (MP4, WebM, HLS, DASH).
• Optimize video storage, retrieval, and delivery performance through CDN, caching, and adaptive bitrate streaming strategies.
• Collaborate on integrating cloud media services (AWS Media Services, Azure Media Services, or GCP Transcoder API) into our stack.

Collaboration & Mentorship

• Collaborate closely with Product, Design, QA, and SRE teams to define technical requirements and deliver business-impacting solutions.
• Mentor junior engineers, providing thoughtful feedback during code reviews and promoting best practices in system design and maintainability.
• Partner with engineering leadership to continuously improve development processes, release reliability, and team efficiency.

Operational Excellence

• Troubleshoot and resolve production issues efficiently, performing deep root-cause analyses and implementing long-term fixes.
• Improve observability, logging, and monitoring to strengthen production reliability.
• Champion engineering excellence through documentation, testing, and continuous improvement initiatives.

Here's What You Need:

• 8+ years of backend engineering experience in large-scale distributed systems or video processing environments.
• Strong command of Python, Go, or Java.
• Deep understanding of video codecs, compression techniques, and streaming protocols (HLS, DASH, RTMP, WebRTC).
• Proven experience with FFmpeg, GStreamer, or similar multimedia frameworks.
• Hands-on experience with cloud-native development on AWS, Azure, or GCP.

Preferred Qualifications

• Experience with real-time streaming (WebRTC, RTMP) or AI/ML-driven media transformation.
• Familiarity with containerization and orchestration (Docker, Kubernetes).
• Experience with observability and monitoring tools (Prometheus, Grafana, Datadog).Knowledge of video watermarking, DRM, or media security practices.
• Contributions to open-source multimedia projects (e.g., FFmpeg, GStreamer) are a plus.
