About the role We're looking for a senior full-stack engineer to support our DX team at Atlassian. Someone who's as comfortable diving into a Ruby on Rails codebase and raw SQL as they are crafting thoughtful, accessible UI in React and TailwindCSS. You'll work end-to-end on features: from shaping vague problem statements with product and design, to shipping high-quality code, to measuring impact and iterating quickly. What you'll do - Design, build, and maintain full-stack features using Ruby on Rails, React, and TailwindCSS. - Write performant raw SQL to power complex queries, reports, and data workflows. - Collaborate closely with product and design to shape problem statements, refine requirements, and propose pragmatic technical solutions when specs are incomplete or ambiguous. - Own projects end-to-end: architecture, implementation, self-QA, rollout, monitoring, and iteration based on customer and stakeholder feedback. - Hold a high bar for quality: write clear, maintainable code, comprehensive tests, and robust monitoring/alerting where appropriate. - Contribute to improving our engineering practices, tooling, and standards, especially around data correctness, reporting, and reliability. Your Background: - 5+ years of industry experience working as a Full Stack Engineer - Bachelor's or Master's degree with a preference for Computer Science degree - Experience crafting and implementing highly scalable and performant RESTful micro-services - Proficiency in using Ruby on Rails, React, and TailwindCSS. - Fluency in any one database technology (e.g. RDBMS like Oracle or Postgres and/or NoSQL like DynamoDB or Cassandra) - Real passion for collaboration and strong interpersonal and communication skills - Broad knowledge and understanding of SaaS, PaaS, IaaS industry with hands-on experience of public cloud offerings (AWS, GAE, Azure) - Familiarity with cloud architecture patterns and an engineering discipline to produce software with quality Compensation At Atlassian, we strive to design equitable, explainable, and competitive compensation programs.

About the teamThe Foundations team builds and evolves the application-level infrastructure that powers Hex. We own the shared backend systems, frameworks, and primitives that other teams depend on—helping the company move faster while maintaining reliability, performance, and security. Our work spans APIs, realtime transport, storage frameworks, background processing, and internal tooling. Rather than shipping isolated features, we focus on creating durable systems that scale with the company and make product development easier for everyone. About the roleWe’re looking for a Senior Backend Software Engineer to help design, maintain, and evolve the core systems used across Hex. This role is centered on backend architecture and shared infrastructure, with responsibility for APIs, realtime communication, data access frameworks, job orchestration, and internal admin tooling. You’ll work closely with product engineering teams to understand their needs, then turn common patterns into robust, reusable systems. You’ll help define standards, influence architecture, and raise the quality bar across the backend. Frontend experience is helpful for understanding end-to-end workflows, but this role is primarily backend-focused. Core ContributionsYou will help contribute to and evolve several foundational areas, including: APIs - GraphQL(schema design, performance, developer ergonomics) - Authentication & authorization(security, scalability, correctness) - Multiplayer & collaboration APIs(realtime state, concurrency) Transport - WebSockets and realtime communication infrastructure Storage Frameworks - Postgres (schema design, query optimization, migrations) - S3, DynamoDB, Redis Job & Workflow Systems - BullMQ and background job processing - Temporal or similar workflow orchestration systems Internal Tooling - Internal admin tools for debugging, operations, and customer support What You'll Do - Design and build backend frameworks and services used across the company - Own and evolve critical shared systems, including APIs, realtime transport, and job orchestration - Improve reliability, performance, observability, and security of foundational backend infrastructure - Partner with product teams to turn recurring needs into shared abstractions - Lead technical design discussions and help set architectural direction - Drive refactors, migrations, and system upgrades that reduce long-term complexity - Improve internal tooling to support debugging, operations, and customer-facing workflows - Mentor other engineers and contribute to strong engineering standards and practices What we're looking for - 5+ years of professional software engineering experience with a strong backend focus - Experience working with Typescript/Node.js and SQL - Experience building and maintaining shared backend systems or frameworks used by multiple teams - Strong understanding of API design, distributed systems, and asynchronous workflows - Experience working with relational databases and data modeling at scale - Familiarity with background job systems, queues, or workflow orchestration tools - Comfort operating and evolving production systems over time - Experience with cloud infrastructure (AWS preferred) - Strong communication skills and a collaborative, leverage-oriented mindset Bonus Points - Experience with Python - Hands-on experience with GraphQL, WebSockets, BullMQ, or Temporal - Familiarity with observability tooling (metrics, tracing, logging) - Background in data platforms, developer tools, or collaborative systems - Experience with frontend technologies (e.g. React, TypeScript) for end-to-end context - Open-source contributions, especially in backend or infrastructure projects Our stackOur product is a web-based notebook and app authoring platform. Our frontend is built with Typescript and React, using a combination of Apollo GraphQL and Redux for managing application state and data. On the backend, we also use Typescript to power an Express/Apollo GraphQL server that interacts with Postgres, Redis, and Kubernetes to manage our database and Python kernels. Our backend is tightly integrated with our infrastructure and CI/CD, where we use a combination of Terraform, Helm, and AWS to deploy and maintain our stack.
