## About the Role

We're looking for someone with at least 1-2 years of professional software engineering experience. We care far more about what you've shipped and how you work than years on a CV.
You might be a generalist who's comfortable moving across mobile, backend, and web, or someone with deep strength in one area who's excited to stretch into others. Either way, you're someone who takes pride in clean, production-quality code - and wants the work to mean something.
You'll need:

 * Strong software engineering fundamentals and production-level experience in at least one modern language (e.g. Kotlin, PHP, Python)
 * Comfort moving across different parts of the stack - mobile, backend, and web - rather than staying in one lane
 * REST API design and integration experience
 * A genuine interest in picking up new languages, frameworks, or platforms as our needs evolve

These would make you stand out:

 * Native Android or iOS development experience (Kotlin, Swift, or Kotlin Multiplatform)
 * PHP/Laravel familiarity
 * Exposure to Apple Wallet / Google Wallet integrations or QR-based flows
 * Python familiarity, for crossover with our smart bin codebase
 * CI/CD experience (e.g. GitHub Actions)
 * Experience with payment SDKs or Stripe
 * A background in hospitality, food service, sustainability, or IoT - not required, but a genuine plus

## Description

As an early team member, you'll receive options that reflect the ground-floor stage we're at. We're growing fast - and when Cauli wins, you win with us.
A Note on Our Environment
Let's be transparent: this is a fast-paced, high-demand start-up environment, and it isn't for everyone. We work in a small, tight-knit team where expectations are high, priorities shift fast, and there are no large corporate safety nets or dedicated account support teams to delegate to. We need a true "do-er"-someone who excels in face-to-face client interactions, loves being out in the field, and thrives under pressure.
The Role
You'll be a driving force across Cauli's engineering, shipping new features and improvements across our mobile apps, backend, web, and hardware-connected software.
Day to day, this means:

 * Developing and maintaining the software behind our suite of technology
 * Building and evolving our mobile apps (iOS and Android), including our unified Kotlin Multiplatform (KMP) codebase
 * Building and maintaining backend services in PHP/Laravel that power our core product
 * Building and maintaining our web app and Apple/Google Wallet integrations as part of our container tracking solution
 * Supporting our smart bin hardware software (Linux SBCs running Python)
