Senior Principal Software Engineer

Technical Leadership & Architectural Strategy

• Serve as the senior technical authority across Dev AI, defining multi-year architectural blueprints, principles, and roadmaps aligned with Atlassian’s broader AI and platform strategy.

• Drive consequential architectural decisions across complex distributed systems, balancing reliability, scalability, security, latency, and inference economics.

• Resolve architectural ambiguity across organizational boundaries, establishing clear ownership, system interfaces, and technical contracts.

Agentic Architecture & SDLC Foundations

• Architect scalable, secure runtimes for autonomous developer agents, including execution sandboxes, tool orchestration, task decomposition, and memory systems.

• Guide code-intelligence capabilities—including code synthesis, automated review, and semantic search—grounded in repository context and the Atlassian Teamwork Graph.

• Establish shared libraries, frameworks, and paved roads that eliminate duplicate effort and standardize agent patterns across teams.

Trust, Reliability & Operational Excellence

• Establish production-readiness bars and engineering standards for availability, customer data isolation, latency, and responsible AI governance.

• Shape technical direction for automated agent evaluation, benchmark frameworks, and telemetry to continuously assess accuracy, cost, and developer adoption.

• Act as a senior escalation point for systemic platform risks and major incidents, driving durable architectural remediations.

Cross-Functional Influence & Engineering Craft

• Partner with engineering directors, product managers, and architects across the CTO organization to align platform roadmaps and resolve critical dependencies without reporting authority.

• Mentor and sponsor senior and principal engineers, elevating the technical caliber and decision-making rigor across distributed teams.

• Remain hands-on with strategic prototypes, architectural validation, and technical hiring calibration across the broader engineering community.

• 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.

• Deep expertise in distributed systems architecture, cloud infrastructure, reliability engineering, and production operations.

• Practical experience designing, building, or operating production-grade AI systems, LLM orchestration frameworks, autonomous agent runtimes, or modern developer tooling.

• Strong understanding of cloud-native compute platforms, containerized environments, secure execution sandboxes, workload isolation, autoscaling, observability, and resilience.

• Proven ability to convert ambiguous business, product, and customer needs into clear architectural direction, roadmaps, and executable technical plans.

• Experience leading complex incident response and turning operational learning into lasting platform improvements.

• Proven ability to influence senior engineers, engineering managers, Directors, and cross-functional stakeholders without direct authority.

• A track record of creating reusable technical capabilities and driving their adoption across multiple engineering teams.

• Strong written and verbal communication skills appropriate for engineers, executives, product partners, and customer-facing stakeholders.

• Experience mentoring senior and principal engineers and raising the technical and architectural capabilities of an engineering organization.

• Experience with secure code execution environments (e.g., microVMs, gVisor, WebAssembly), vector databases, retrieval-augmented generation (RAG), graph data systems, automated evaluation frameworks, or developer platform APIs is beneficial but not required.
