Senior Software Engineer, Creative Ads

KERV.ai is an award-winning company transforming how content and commerce converge in media. They are seeking a Senior Software Engineer to build visual products for their Creative Ads team, focusing on the dynamic video generation pipeline and interactive ad experiences.

Responsibilities:

• Build and maintain our dynamic video generation pipeline — a multi-stage, serverless orchestration system on AWS that produces video creatives at scale
• Develop and improve our video template studio and interactive overlay applications using modern frontend frameworks (React, Svelte)
• Collaborate closely with product managers, designers, and creative teams to translate ad concepts into shippable features
• Proactively design and run A/B tests on ad formats, creative treatments, and user experiences to drive measurable performance improvements
• Help harden production systems: improve observability (CloudWatch, logging), error handling, CI/CD pipelines, and cost/performance tuning across the video pipeline
• Contribute to architectural decisions, weighing long-term maintainability against short-term delivery needs
• Write clean, well-tested code across a diverse codebase — from serverless pipeline orchestration to client-facing ad experiences where visual quality and stability are immediately visible
• Participate in team code reviews, sharing knowledge and learning from others
• Participate in sprint planning, ensuring that realistic plans are set forth and delivered
• Communicate effectively within the engineering team and with non-technical teams
• Have the discipline to shift between establishing new features and maintaining legacy features based on the needs of the business

Requirements:

• 3–7+ years of professional experience developing web-based applications
• Strong experience with JavaScript/TypeScript across both frontend and backend
• Professional experience with React; additional experience with Svelte is a plus
• Experience with Node.js in production environments
• Working knowledge of AWS services, particularly Lambda, S3, and Step Functions — or comparable cloud infrastructure experience
• Comfort working across the stack, from UI components to serverless backend services
• Ownership mindset — you can take responsibility for a slice of the system end-to-end, propose tradeoffs, and collaborate closely with teammates through pairing, code review, and clear communication
• Strong asynchronous communication skills, ensuring efficient and effective collaboration with remote team members
• Experience with or strong interest in AI-driven prompt engineering and AI coding assistants
• Experience with video processing technologies (FFmpeg, transcoding, video playback, MediaConvert)
• Familiarity with Adobe After Effects or the Adobe Creative Suite, particularly Lottie/JSON export workflows
• Experience with browser automation tools (Puppeteer, Playwright)
• Background in animation systems, 2D graphics programming, or creative tooling
• Python experience, particularly in media/video processing contexts
• Experience with the Serverless Framework or similar IaC tools
• Digital advertising experience, specifically with video ad technologies (VAST, VPAID)
• Experience with A/B testing frameworks and experimentation methodology
• Experience developing an enterprise or SaaS product
• Previous experience in a startup environment
