Senior Principal Software Engineer, Dev AI

About the role

Atlassian's Dev AI engineering organization builds AI-native developer experiences and autonomous software development lifecycle capabilities for Jira, Bitbucket and the Atlassian Teamwork Graph. It is looking for a Senior Principal Engineer to provide organization-wide technical leadership across its Dev AI platforms and agentic developer initiatives, shaping the multi-year architecture of autonomous developer agents, runtime sandboxes, agent orchestration engines and context-retrieval infrastructure. The role is remote, full-time, and open to candidates located in the United States.

Key responsibilities

• Serve as the senior technical authority across Dev AI, defining multi-year architectural blueprints, principles and roadmaps aligned with Atlassian's AI and platform strategy.
• Drive architectural decisions for complex distributed systems, balancing reliability, scalability, security, latency and inference economics.
• Architect scalable, secure runtimes for autonomous developer agents, including execution sandboxes, tool orchestration, task decomposition and memory systems.
• Guide code-intelligence capabilities such as code synthesis, automated review and semantic search grounded in repository context and the Teamwork Graph.
• Establish shared libraries, frameworks and paved roads that standardize agent patterns across teams.
• Set production-readiness standards for availability, data isolation, latency and responsible AI governance, and shape evaluation, benchmark and telemetry frameworks.
• Act as a senior escalation point for platform risks and major incidents, mentor and sponsor senior and principal engineers, and partner with engineering directors, product managers and architects across the CTO organization.

Required profile

• Significant experience as a senior technical leader for large-scale distributed systems, developer platforms, AI/ML systems, cloud infrastructure or comparable business-critical platforms.
• Demonstrated success setting technical direction and delivering multi-team or multi-organization platform initiatives.
• Proven ability to convert ambiguous business, product and customer needs into architectural direction, roadmaps and executable plans.
• Experience leading incident response and turning operational learning into lasting platform improvements.
• Ability to influence senior engineers, engineering managers, directors and cross-functional stakeholders without direct authority.
• Track record of creating reusable technical capabilities and mentoring senior and principal engineers.

Required skills

• Deep expertise in distributed systems architecture, cloud infrastructure, reliability engineering and production operations.
• Production-grade AI systems, LLM orchestration frameworks, autonomous agent runtimes or modern developer tooling.
• Cloud-native compute, containerized environments, secure execution sandboxes, workload isolation, autoscaling, observability and resilience.
• Beneficial: secure code execution environments (microVMs, gVisor, WebAssembly), vector databases, RAG, graph data systems, automated evaluation frameworks or developer platform APIs.
