Actively hiring Posted 2 days ago

Role overview

We're looking for someone with:

  • Strong Python fundamentals and software engineering discipline
  • Experience building classification and NLP systems
  • LLM prompt engineering and optimisation (token efficiency, few-shot design, chain-of-thought)
  • Evaluation methodology: building ground truth datasets, A/B testing, accuracy measurement
  • Production ML experience: model serving, latency optimisation, monitoring
  • Comfort with ambiguity and novel problem domains

Computer Science Background - with caveat. *If you don't have a CS background, you're challenged to beat one of the founders in a 1:1 whiteboard duel on DS&A judged by Hung. Neither founders have formal CS background, but come prepped.

There will be an expectation to stay up to business context, which could involve:

  • Watching key customer calls
  • Interacting with customers
  • Helping with product thinking

What we're looking for

  • Experience with hybrid ML/rule-based systems
  • OCR, document understanding, or computer vision background
  • Cost optimisation for LLM-heavy systems
  • PyTorch or similar framework experience
  • Familiarity with process mining or workflow analysis
  • You've shipped ML systems that operate at scale under real constraints
  • Interesting personal projects that demonstrate depth

Interview process

  • Resume screen
  • 1:1 with founder
  • Technical deep-dive on past ML work
  • Work through a real problem with the team
  • Offer

We strongly encourage applicants from underrepresented backgrounds to apply. Diverse teams build better products - see value #5.

Compensation Range: $150K - $250K
