Lead Software Engineer - AI
Melbourne | Full-time | Flexible / Hybrid
triniti is recruiting on behalf of a fast-growing SaaS company that's building real, production-grade AI - not demos or experiments.
We're looking for a Lead Software Engineer who wants ownership. Someone who can set technical direction, build critical AI systems hands-on, and lead from the front as the product scales.
This role sits right at the intersection of LLMs, structured enterprise data, and real customer outcomes.
Why You'll Care
You'll own the AI stack end-to-end - architecture, delivery, quality, and operations
You'll build LLM-powered features that actually ship (RAG, tools, workflows, agents)
You'll work on hard problems: reliability, grounding, latency, cost, and scale
You'll help define how AI is done properly inside a growing SaaS business
This isn't research. This is AI in production.
What You'll Do
Lead AI technical strategy and delivery across the platform
Build and ship core AI services, APIs, retrieval pipelines, and workflows
Design grounded, traceable AI outputs that users can trust
Implement hybrid retrieval (structured search + semantic ranking)
Create evaluation frameworks to prevent silent quality regressions
Own LLMOps: monitoring, debugging, reliability, and cost controls
Mentor engineers and raise the technical bar across the team
What We're Looking For
Strong backend-first engineer with a track record of shipping production systems
Tech: C#, Python, Azure, Databricks, TypeScript
Hands-on experience with LLMs (RAG, tool calling, orchestration, prompt versioning)
Comfortable owning systems in production - not just prototypes
Solid data fundamentals (SQL, APIs, data modelling)
Clear communicator who can make smart trade-offs and move fast
Bonus Points
Search, retrieval, or ranking systems
Experience in regulated or data-sensitive environments
LLM cost optimisation and performance tuning
Experience in data-heavy domains (finance, insurance, healthcare, marketplaces)
The Upside
Huge ownership and influence
Flexible working
Real product impact
A team that cares about quality
