Role
Who you are
- Things move quickly here. Requirements evolve, new opportunities emerge, and we need someone who thrives in that environment
- If you're an expert Java engineer and already experimenting with Claude, Gemini, and agentic workflows—and you want to do that at scale in a world-class engineering team—this is the role for you
- Deep Java expertise combined with hands-on experience building scalable distributed systems on AWS—you write great code and think seriously about architecture
- Proven experience working on agentic AI systems—you understand how they differ from traditional systems, you've built or led features in this space, and you have a point of view on how to test and scale them
- Technical leadership experience—you've been a tech lead, influenced architecture decisions, and helped other engineers grow; you can communicate complex concepts to non-technical stakeholders without breaking a sweat
- Full stack capability is a strong plus—particularly React, TypeScript, and Tailwind—and familiarity with frameworks like Langchain or Langgraph would be welcome
- Adaptable and fast-moving—you thrive in an environment where requirements evolve, you're comfortable with ambiguity, and you have a genuine bias for action when it comes to adopting and championing new technologies
- We are keen to hear from prospective Matillioners, so even if you don't feel you match all the criteria please apply and a member of our Talent Acquisition team will be in touch
What the job involves
- As a Principal Software Engineer on our Maia team, you'll be at the heart of everything we do: working on agentic AI systems, building new tools and integrations, and staying finger-on-the-pulse with the latest developments in Gen AI. This isn't BAU engineering—this is high-visibility, high-impact work where your decisions shape the product
- You'll be driving architecture, mentoring engineers, and feeding into strategy
- Lead technical architecture and design for the Maia team—working across two squads to define direction, validate proposals, and ensure we're building scalable, maintainable software at pace
- Drive agentic AI feature development—building new tools, integrations, and workflows that push the boundaries of what our Data Productivity Cloud can do
- Stay ahead of the curve on Gen AI developments—trialling new models, tools, and approaches, feeding insights into team strategy and championing new ways of working
- Act as technical mentor and coach to engineers across the team—raising the bar through code reviews, design input, and hands-on guidance
- Collaborate closely with our Product Manager and Data Science team to translate product vision into technical reality, balancing innovation with code quality and delivery pace
