Software Engineer/Senior Software Engineer - AI Platform (Agent Cell)
About The Position
The Agent Runtime team builds Workday’s secure execution platform for enterprise AI agents. The team is creating a runtime substrate that enforces policy through architecture, with deterministic controls for data access, tool use, model routing, and auditability. Its work spans runtime isolation, policy enforcement boundaries, model mediation, and observability at scale, in partnership with other Workday engineering and platform teams. The role has Software Engineer and Senior Software Engineer scopes. The Senior Software Engineer designs and builds core runtime capabilities for policy-governed agent execution, owning high-impact areas such as sandbox execution, sidecar interfaces, enforcement flows, and production reliability. The Software Engineer implements key runtime components and services, contributing to design, coding, testing, and operations for systems that enforce policy and reliability guarantees in production.
Requirements
- For Software Engineer: 5 or more years of software development engineering experience, including designing, developing, and deploying software solutions.
- For Senior Software Engineer: 8 or more years of software development engineering experience architecting, building, and scaling robust and efficient software systems.
- For Senior Software Engineer: 6 or more years of software engineering experience with platform systems.
- Strong experience with distributed systems, APIs, and service-oriented architecture.
- Proficiency in at least one systems or backend language, such as Python, Rust, Java, or Go.
- Proficiency with infrastructure-as-code tools such as Terraform.
- Experience building secure systems with least-privilege patterns and policy controls.
- Experience operating production services with strong reliability and observability practices.
- Demonstrated ownership of complex technical projects from design through production.
- Strong collaboration and communication skills in cross-functional environments.
Responsibilities
- 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 observability into runtime behavior, policy decisions, and audit traces.
- Partner with cross-functional teams to integrate data preparation, 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.
- Build backend services and runtime components for cell lifecycle and execution control.
- 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 with senior engineers and partner teams on roadmap delivery.
Benefits
- The role may be eligible for the Workday Bonus Plan or a role-specific commission or bonus.
- Annual refresh stock grants may be included in the total compensation package.
- Workday offers a comprehensive benefits package.
