Senior Software Engineer – Agent Systems

As a Senior Software Engineer on the Agent Systems team at Kraken (Payward), you'll build internal AI-powered agents that interact directly with company systems to dramatically increase execution speed through automation, intelligent inference, and workflow orchestration. This is a 0→1 engineering group operating at the intersection of AI, backend systems, and applied product engineering, where you'll move fluidly between rapid experimentation and shipping production-grade systems.

What you'll do

• Build and ship AI-powered agent systems that automate internal workflows and decision paths
• Design and implement inference pipelines that reason over user interactions across internal systems
• Prototype quickly to validate agent behaviors, then productionize what proves valuable
• Architect backend services that integrate with multiple internal APIs and data sources
• Define patterns for safe, observable, and controllable agent execution
• Collaborate cross-functionally to identify high-leverage automation opportunities
• Improve system speed, reliability, and signal quality as usage scales
• Contribute to foundational design decisions for a 0→1 agent platform

What you bring

• 5+ years of experience building and shipping production software systems
• Strong backend engineering fundamentals including APIs, distributed systems, data modeling, and reliability
• Experience building fullstack systems, with comfort working across backend and occasional frontend surfaces
• Hands-on experience working with AI/ML systems, LLMs, or inference pipelines in production
• Ability to prototype rapidly while maintaining a clear path to production-grade architecture
• Strong systems thinking: ability to reason about orchestration, failure modes, and observability
• Comfort operating in ambiguous, 0→1 environments with high ownership

Nice to have

• Experience building or operating agent-based systems or autonomous workflows
• Familiarity with prompt engineering, evaluation frameworks, or model performance tuning
• Experience integrating with internal enterprise systems such as CRM, support tools, and analytics platforms
• Background in building developer platforms or internal tooling
• Experience designing guardrails, sandboxing, or safety layers for AI systems
