What they need
- The Agent Runtime team builds Workday’s secure execution platform for enterprise AI agents
- We are creating the runtime substrate that enforces policy by architecture, not by prompt, with deterministic controls for data access, tool use, model routing, and auditability
- Our charter spans runtime isolation, policy enforcement boundaries, model mediation, and observability at scale. We partner closely with other engineering and platform teams at Workday to deliver a multi-language, enterprise-grade agent runtime
- As a Senior Software Development Engineer, you will design and build core runtime capabilities for policy-governed agent execution. You will own high-impact technical areas across sandbox execution, sidecar interfaces, enforcement flows, and production reliability
- Design and implement core runtime services for secure, isolated agent execution
- Build deterministic enforcement pathways for data, context, tool, and model boundaries
- Define and evolve service interfaces and contracts across maincar and sidecar components
- Improve performance, scalability, and resilience for high-concurrency workloads
- Build deep observability into runtime behavior, policy decisions, and audit traces
- Partner with cross-functional teams to integrate data prep, context assembly, tool gating, and model mediation
- Participate in architecture reviews, incident response, and operational hardening
- Mentor engineers and help raise engineering quality across the team
- As a Software Development Engineer III on the Agent Runtime team, you will implement key runtime components and services that power secure agent execution
- You will contribute to design, coding, testing, and operations for systems that enforce policy and reliability guarantees in production
- Build backend services and runtime components for cell lifecycle and execution control
- Implement policy-aware data, context, tool, and model access pathways
- Contribute to interface development between runtime components and partner systems
- Write high-quality, testable code and participate in code and design reviews
- Develop telemetry and logging capabilities for traceability and operational insight
- Support production operations, performance tuning, and incident follow-through
- Collaborate closely with senior engineers and partner teams on roadmap delivery- Experience building and shipping production services with testing and monitoring
- Proficiency in at least one systems or backend language (for example, Java, Go, Rust, or Python)
- 3+ years of software engineering experience in backend or platform development
- 5+ years experience in software development engineering including designing, developing, and deploying software solutions
- Strong written and verbal communication skills and effective team collaboration
- Working knowledge of security fundamentals, including authentication, authorization, and least-privilege concepts
- Strong collaboration and communication skills in cross-functional environments
- Experience building secure systems with least-privilege patterns and policy controls
- Solid foundation in distributed systems fundamentals, APIs, and data modeling
- Strong experience with distributed systems, APIs, and service-oriented architecture
- 6+ years of software engineering experience building backend or platform systems
- Ability to debug complex issues and deliver reliable fixes in production environments
- Demonstrated ownership of complex technical projects from design through production
- 8+ years experience in software development engineering, architecting, building, and scaling robust and efficient software systems
- Experience operating production services with strong reliability and observability practices
- Proficiency in one or more programming languages used for backend systems
