About The Position

Our client is building a loyalty platform for mobile gamers that helps users discover games, connect with friends, and earn rewards. As the first dedicated engineer on the SDK, you will own its architecture, public API, releases, and partner experience end to end. The role focuses on building automated AI-video workflows and pipelines for marketing creative production, in collaboration with AI-video creative specialists.

Requirements

• Hands-on generative AI experience with fal.ai and ComfyUI, demonstrated through workflows or applications you have built.
• Strong Python or TypeScript skills for workflow automation, API integration, asynchronous processing, background jobs, and error handling.
• Ability to build modular, configuration-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, and selecting models based on quality, cost, and 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.
• Ability to write clear, maintainable code and documentation so marketing staff can operate workflows without writing code.
• Good English communication skills and ability to collaborate with AI-video creative specialists.
• Be prepared to share your screen and walk through a working pipeline or application, explaining your technical contribution.

Nice To Haves

• Experience with Stable Diffusion, LoRA training, or evaluating character consistency.
• Experience building internal applications for creative teams or scaling automated video production.
• Familiarity with paid mobile user-acquisition creatives and CTR, CPI, or ROAS.
• Experience with agent-driven or AI-assisted video editing.

Responsibilities

• Build modular, configuration-driven workflows for 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 pipeline runs resumable so failures do not trigger duplicate generation costs.
• Fetch and cache UI assets, then use FFmpeg to assemble clips, add subtitles and calls to action, synchronize talking-head audio, and mix sound.
• Produce video ads in 9:16 and 1:1 formats.
• Document the pipeline and provide configuration examples that allow the marketing team to use workflows without writing code.

Benefits

• Flexible working hours.
• 29 days of PTO (18 working days per year plus all national holidays).
• 10 paid recovery days.
• Full financial and legal support for independent contractors.
