Job summary

MWDN Ltd. is seeking a hands-on AI video engineer to join our international product team. You will build modular, config-driven workflows for avatars, scripts, voices, and video assets, and integrate APIs to manage jobs, retries, and cost tracking.

You will own the SDK architecture and the end-to-end partner experience. The role emphasizes strong Python/TypeScript skills, experience with generative AI models, FFmpeg, and scalable pipelines.

Qualifications

• Hands-on experience with generative AI, fal.ai, and ComfyUI, supported by workflows or applications you have built.
• Strong Python or TypeScript skills to automate workflows, integrate APIs, and handle async processing, background jobs, and errors.
• Ability to build modular, config-driven pipelines that generate multiple variations by changing avatars, scripts, and other creative elements while reusing assets.
• Experience integrating image, video, text-to-speech, and talking-head models, selecting models based on quality, cost, and the use case.
• Practical FFmpeg experience with clip assembly, UI overlays, subtitles, audio mixing, and aspect-ratio formatting.
• Ability to implement reliable job orchestration, retries, resumable execution, and cost tracking.
• Clear, maintainable code and documentation that allows marketing staff to operate workflows without writing code.
• Good English communication and the ability to collaborate with AI-video creative specialists.

Responsibilities

• Build modular, config-driven workflows covering scripts, hooks, avatars or LoRAs, voices, music, UI assets, and aspect ratios.
• Integrate the fal Queue API to manage jobs, rate limits, webhooks, and retries.
• Make runs resumable so failures don’t trigger duplicate generation costs.
• Fetch and cache UI assets, then use FFmpeg to assemble clips, add subtitles and CTAs, sync talking-head audio, and mix sound.
• Produce video ads in 9:16 and 1:1 formats.
• Document the pipeline and provide configuration examples that the marketing team can use without writing code.
