Senior AI Engineer - Growth @ Kraken | Blockchain Capital Job Board
About this role
The Role We’re building an AI-native growth engine — one where agents make distribution decisions, creative is generated and iterated at scale, and the system compounds intelligence across every product simultaneously. This is not automation bolted onto existing workflows. It is a new model entirely. As AI Engineer, Growth, you will be the second builder on this engine. Working alongside our lead architect, you execute — building, shipping, and iterating the agent orchestrations, automated workflows, and system integrations that power every growth work-stream: paid growth, lifecycle, organic search, CRO, incentives, referrals, and beyond. This role is for someone who moves fast, builds from specs without needing hand-holding, and cares deeply about the quality of what they ship. If you’ve spent your career wanting to build systems that actually run growth rather than just support it — this is that role. The opportunity WHAT YOU’LL BUILD • Agent orchestration workflows across growth use cases — automating the decisions and executions that today require human intervention across paid media, lifecycle messaging, organic content, conversion optimization, incentives, and other growth levers • Integrations between our AI reasoning layer, growth execution platforms, data infrastructure, experimentation systems, and analytics tools • Shared agent infrastructure components — reusable workflow patterns, prompt libraries, and integration clients that every growth workstream draws from • Monitoring and audit logging — ensuring every agent action is traceable, versioned, and queryable for governance and continuous improvement • Creative and content generation pipelines — automating the brief-to-variant-to-distribution loop across growth channels WHAT YOU’LL OWN • Build velocity across new growth workstreams — you are the person who gets workflows from spec to production • Integration reliability — connections between systems work, handle errors gracefully, and are maintained as tools evolve • Workflow documentation — every workflow you build is documented clearly enough that a domain specialist can understand, tune, and improve it without your involvement What you bring • 3+ years building automation workflows, integrations, or agentic systems — using AI orchestration platforms, workflow automation tools, or equivalent technologies • Strong understanding of API integrations — REST, webhooks, authentication patterns, and error handling at scale • Experience working with LLM APIs — prompt engineering, structured outputs, tool use, and agent chaining • Comfort working from a spec — you can take a workflow design and build it accurately without the architect in the room • Growth or marketing context — you understand what you’re building toward, not just how to build it • Speed and quality in balance — you ship fast and you care what you ship Nice to haves • Experience with paid media platforms, marketing automation, CRM, or lifecycle messaging systems • Familiarity with data warehouse query patterns and event tracking infrastructure • Background in a high-growth fintech, consumer tech, or multi-product technology environment • Experience designing multi-agent architectures or complex agent-to-agent workflows Unless a specific application deadline is stated in the job posting, applications are accepted on an ongoing basis.
