About Us
At Relevance AI, we’re building the home of the AI workforce.
Our mission is simple: empower every team to delegate meaningful work to AI agents that think, act, and collaborate like experts.
With Relevance AI, anyone can create and manage intelligent agents that handle workflows, decisions, and collaboration - all within one unified platform. Our technology already powers industry leaders such as Canva, Databricks, Confluent, Autodesk, Lightspeed, Rakuten, Aveva, Qualified, and Activision Blizzard, helping them scale excellence across operations, marketing, and sales.
We’re backed by Bessemer Venture Partners, Insight Partners, Peak XV, and King River Capital, and raised our Series B in April 2025 to accelerate growth and push the boundaries of agentic automation.
Headquartered in San Francisco and Sydney, we operate on a hybrid model and thrive on curiosity, collaboration, and execution - we move fast, think big, and win together.
In 2025, we were proud to be named LinkedIn’s #1 Startup in Australia.

The Role
We’re hiring for Staff Software Engineers (Full-Stack / Back-End) to work across our core engineering teams in Sydney.
Each team at Relevance AI is tackling a different frontier of the AI workforce — from the core agent and tool builder experience, to the conversational layer that powers real-time agentic chat, to the enterprise-grade platform capabilities that serve our largest and most demanding customers. Regardless of where you land, you'll be building systems that make AI usable, reliable, and production-ready.
Our roles would be ideal for an engineer who enjoys solving deep technical problems, designing robust scalable systems, and owning complex projects end-to-end in close collaboration with product and customer-facing teams.
In return, you'll receive real autonomy and trust: shipping to customers within hours, leading complex projects end-to-end, and shaping how we build as we scale. No unnecessary layers of approval — just high ownership, high impact work.
Our supportive, fast-paced culture fosters collaboration, curiosity, and creativity, making it an environment where innovation thrives and where your ideas and expertise will be highly valued.
Your Impact
Lead the design and implementation of complex, production-grade systems that underpin our platform at scale.
Provide architectural guidance and cross-team technical leadership, ensuring consistency, reliability, and long-term maintainability.
Own significant platform surface areas end-to-end — from system design through to deployment, observability, and iteration.
Partner with product, go-to-market, and engineering leadership to translate customer and business requirements into clear technical strategies.
Mentor and level-up engineers within and beyond your immediate team, fostering a culture of technical excellence and ownership.
Shape engineering standards, processes, and best practices as we scale across the organisation.
Our Tech Stack (so far)
We leverage a modern, scalable, and developer-friendly technology stack to build robust web applications:
Frontend: React, Vue.js, Typescript
Backend: Express.js, Node.js, Typescript
Database: PostgreSQL, MongoDB
Cloud Infrastructure: AWS, Vercel, Terraform, Kubernetes
AI Coding Tools: Claude Code, Cursor, Codex and more
What We’re Looking For
6+ years of hands-on software engineering experience(full-stack or back-end focussed), ideally within fast-paced, high-growth and complex technical environments.
Clear evidence of operating at Staff scope — driving architecture, mentoring teams, and influencing technical direction across multiple squads or projects.
Strong technical foundations in cloud infrastructure and APIs (preferably AWS, Node.js, REST/GraphQL).
Comfortable working with both technical and non-technical stakeholders, translating complex requirements into actionable technical strategies.
Demonstrated ability to own complex, ambiguous problems end-to-end and consistently deliver high-quality, high-impact outcomes.
Customer-centric mindset — you think about reliability, scalability, and the downstream effects of technical decisions on real users.
Deep interest in AI and enthusiasm for building category-defining products.
Actively leverages AI coding tools in your day-to-day workflow and stays current with the latest developments.
Bonus Points if You Have Any Of The Following
Experience building AI features leveraging LLMs, agent workflows, or AI infrastructure.
Experience building enterprise features and systems — IAM, SSO, audit logs, compliance frameworks, or observability.
Experience building integrations ecosystems or native third-party connectors.
Contributions to open-source projects.
