As a Principal Full Stack Software Engineer (P60) on Starburst, you will serve as the lead technical anchor for multi-quarter onboarding and cross-flow initiatives across Atlassian's product suite. You will bridge complex frontend micro-frontends with robust backend integration services and experimentation infrastructure.
Working at Atlassian
Atlassians can choose where they work – whether in an office, from home, or a combination of the two. That way, Atlassians have more control over supporting their family, personal goals, and other priorities. We can hire people in any country where we have a legal entity.
What You’ll Do
Lead System Architecture: Define the technical vision and architectural patterns for multi-product Onboarding and CrossFlow experiences across Confluence, Loom, and TWC.
Build End-to-End Solutions: Write production-grade code for high-complexity full stack features spanning React/TypeScript micro-frontends and scalable backend microservices.
Champion Growth Engineering: Architect fast, robust experimentation frameworks and instrumentation (Statsig, telemetry) to power rapid hypothesis testing and conversion optimization.
Bridge Multi-Product Teams: Partner across product boundaries (Loom, Confluence, Platform) to deliver seamless shared surfaces and cohesive API contracts.
Drive Operational Excellence: Safeguard application performance, reliability, and observability while driving down operational toil and defect rates.
Multiply the Team: Mentor senior engineers, author high-impact RFCs/tech specs, and elevate the technical craft across the Growth organization.
1. Technical Architecture & Cross-Product Systems
Architect cross-product surfaces: Lead the technical strategy and architecture for end-to-end user journeys connecting Loom, Confluence, and Jira (e.g., embedding Loom async video capture/preview within Confluence or Jira workflows).
Define clean integration patterns: Design robust API contracts (GraphQL, REST) and modular micro-frontend components that embed seamlessly into disparate host applications without causing performance or latency regressions.
Author foundational Technical Specs & RFCs: Write comprehensive technical specifications, evaluate build-vs-buy decisions, and drive technical consensus across multiple engineering squads and platform teams.
2. Growth Experimentation & Telemetry Rigor
Drive high-velocity experimentation: Partner with Product Managers and Data Scientists to design, instrument, and launch complex A/B and multivariate experiments (using Statsig/feature flags) to accelerate trial starts, activation, and conversion.
Build clean experiment architectures: Structure frontend and backend code so experiments can be launched, modified, and cleaned up quickly without accumulating unmanaged tech debt.
Own attribution & telemetry pipelines: Ensure accurate end-to-end event logging and funnel telemetry to maintain high data fidelity and minimize Time-to-Detect (MTTD) for funnel or attribution bugs.
3. Hands-on Execution & Foundational Prototyping
Deliver complex/foundational code (60–70% hands-on): Build critical paths, shared libraries, and proof-of-concept prototypes that pave the way for other engineers.
Lead platform consolidation & modernization: Decommission legacy flows, unify fragmented onboarding/activation mechanisms, and build reusable patterns for cross-flow journeys.
4. Cross-Functional Collaboration & Triad Leadership
EPD Triad Partnership: Work closely with Product Management, Product Design, and Data Science from early ideation through execution and post-launch experiment analysis.
Partner across org boundaries: Align with core product teams (e.g., Confluence Core, Loom Engineering, Platform/Identity, Commerce) to resolve shared dependencies and navigate host-app constraints.
5. Operational Health, Performance & Reliability
Uphold performance & latency guardrails: Ensure onboarding modals, embedded video players, and cross-flow triggers do not degrade host-page load times or core web vitals.
Reduce operational toil (Run the Business / RtB): Implement automated testing, CI/CD improvements, and proactive monitoring/alerting to reduce on-call burden and eliminate recurring hotfixes.
6. Mentorship, Craft & Team Multiplier
Mentor and grow talent: Coach Senior (P40) and Lead (P50) engineers on system design, technical writing, and growth engineering practices.
Elevate engineering standards: Lead code and architectural design reviews, champion Atlassian engineering values, and contribute to hiring and interview loops.
Senior Technical Leadership: 8–12+ years of full stack software engineering experience, with demonstrated impact at a Staff/Principal level leading large, ambiguous multi-team initiatives.
Growth & Experimentation Mindset: Deep experience operating in growth-focused environments (onboarding, activation, conversion funnels, viral loops, or product-led expansion), with strong familiarity in statistical experimentation (MDEs, power, guardrail metrics).
Modern Frontend Mastery: Deep expertise in TypeScript, React, modern state management, frontend performance optimization, micro-frontends, and accessible component architectures.
Scalable Backend Systems: Strong proficiency in backend service development (Java, Kotlin, Go, or Python), GraphQL / RESTful APIs, microservices, and AWS cloud infrastructure.
Cross-Product Integration Expertise: Experience designing extensible APIs and shared UI components that embed cleanly across multiple independent host applications.
Data & Instrumentation Rigor: Hands-on experience with telemetry pipelines, event tracking schema design, and data querying (SQL/analytics tools) to diagnose funnel drop-offs and attribution.
Collaborative Leadership: Exceptional communication skills with a proven track record of aligning engineers, PMs, designers, and data scientists around complex architectural trade-offs.
